What do we mean by the efficiency of a heat pump?

The efficiency of a heat pump is usually expressed in:

• COP (Coefficient of Performance) – the efficiency at a given time
• SCOP (Seasonal COP) – the average annual efficiency over all seasons

What exactly does COP say?

COP 4 means that for 1 kWh of electricity, you receive about 4 kWh of heat. The higher the COP, the lower your energy bill.

What does SCOP say?

SCOP looks at:

• outdoor temperature in all seasons
• moments of use
• start-up and defrost cycles

Modern air-water heat pumps often achieve a SCOP between 3.5 and 4.5, even in the Netherlands.

Why does outside temperature have so much influence?

A heat pump extracts heat from the outside air. The lower the outside temperature, the harder it becomes to extract heat. As a result, the heat pump has to work harder and its efficiency drops slightly. Nevertheless, a modern heat pump remains efficient and reliable even in freezing temperatures.

COP at different outdoor temperatures:

These values vary by heat pump type, home and installation quality.

Up to what outside temperature does a heat pump operate?

Many people wonder up to what temperature a heat pump works well. The good news is that this is not a problem. Air-water heat pumps typically function down to -15 °C, while modern systems even work down to -20 °C. A hybrid heat pump automatically switches to the boiler when needed. This keeps your home comfortably warm no matter the weather.

Heat pump efficiency in winter: how big is the difference?

The efficiency of a heat pump drops in winter, but not nearly as dramatically as is often thought. Even at 0 °C, a heat pump still delivers 2 to 3 times as much heat as it consumes in electricity. This keeps a heat pump:

• cheaper than gas

• more sustainable

• stable and reliable

Why heat pumps perform better and better in cold weather

Modern heat pumps become more efficient every year due to powerful modulating compressors and improved refrigerants. Smart, economical defrost cycles and an optimized heat exchanger provide additional efficiency. High-performance monoblock and split technology further improve performance. Thanks to these innovations, heat pumps work extremely well, even in the relatively mild Dutch climate.

How does a heat pump defrost cycle work?

In humid and cold air, ice can form in the outdoor unit. The heat pump then briefly switches to a defrost cycle. You may see temporary plumes of steam or experience a brief drop in heat production. This is normal and usually lasts only a few minutes.

Hybrid heat pump: smart at low temperatures

Do you want security and savings? Then a hybrid heat pump is an excellent choice. You save up to 70% of gas. In extreme cold, the system automatically switches to the boiler. So you always enjoy high comfort and heat guarantee. Moreover, the investment is lower than with a fully all-electric heat pump.

What does this mean for your energy bill?

Even if the efficiency drops slightly in cold outdoor temperatures, a heat pump is still very attractive financially. This is because you benefit from significantly lower energy costs and a sharp reduction in your gas consumption. In addition, the energy label of your home increases, you reduce CO₂ emissions and you often qualify for attractive ISDE subsidies.

ISDE subsidy for heat pumps

Government encourages sustainability. Indicative amounts:

• Hybrid heat pump: €2,400 – €3,000
• Air-water heat pump: €2,550 – €3,750

We will, of course, help you with:

• grant advice
• required documentation
• proper placement (required for grant)

Choose a heat pump that fits your home

Our advice is to always choose a heat pump that fits your home. No two homes are the same, so it is important that the heat pump fits your situation perfectly.

On this basis, we advise you personally and take the entire process off your hands, so that you are completely relieved.

Modern heat pumps work efficiently even at low outside temperatures. Don’t let cold weather deter you. They are designed to perform reliably, economically and quietly, even in freezing temperatures. At The Sustainable Boys, we are happy to help you with clear and honest advice. That way you will know exactly which heat pump suits your home and what you can save annually.

What exactly do the BENG regulations entail?

BENG requirements focus on three main indicators that determine a building’s energy performance:

• The maximum energy requirement per square meter per year for heating, cooling and ventilation;
• Primary fossil energy use, which indicates the maximum amount of fossil fuels that can be consumed;
• The minimum proportion of renewable energy that the building must provide.

These regulations ensure energy savings and reduced CO2 emissions in homes. Since 2021, these requirements have applied to new construction, and starting in 2026 the regulations will be further tightened.

Is a home battery safe? The facts about home battery safety

Modern home batteries are designed according to strict European safety standards. They are extensively tested for fire safety, voltage, temperature and shock resistance. Most home batteries use lithium iron phosphate (LiFePO₄), a battery technology known to be particularly stable and thermally safe. These cells have a low risk of overheating, even under prolonged use or high loads.

Many people think that home batteries can easily explode or catch fire, but that is a misconception. Such incidents occur almost exclusively with poorly installed or outdated systems. If you choose a licensed installer and a certified brand, the chances of problems are minimal.

How the safety of your home battery is truly guaranteed

The safety of a home battery is the result of multiple layers of protection. Each battery is equipped with a Battery Management System (BMS) that continuously monitors voltage, temperature and charge status. This system automatically intervenes when values fall outside the safe range, such as by stopping charging or discharging.

In addition, most home batteries have integrated fire protection and temperature sensors. Some models feature a cooling system that prevents overheating. Also, the housing is made of fire-resistant materials that can withstand high temperatures. Regular maintenance and software updates keep the system functioning optimally and safely.

Where may a home battery be located for maximum safety?

Where you place a home battery is important for both safety and efficiency. The best location is a well-ventilated, dry room where the temperature remains stable. Popular places include the garage, storage room or an indoor technical area. Make sure the battery is not directly exposed to sunlight, moisture or extreme cold.

Avoid small enclosed spaces without ventilation and never install the battery next to flammable materials. Current safety guidelines require sufficient clearance around the battery for air circulation and inspection. Some manufacturers provide specific instructions on minimum distances from walls or other equipment. Always follow these carefully for maximum safety.

Installing home battery without fire hazard: here’s how to do it

Installing a home battery is not a do-it-yourself job. Installation should always be performed by a licensed installer familiar with applicable standards. During installation, all electrical connections are checked and fused, and the battery securely mounted against vibration and impact. Important points of interest for safe installation:

Why WTW ventilation in an existing home is a good idea

A good ventilation system is important for healthy and energy-efficient homes. WTW ventilation (also called balanced ventilation) removes polluted air and brings in clean, pre-heated air. This provides multiple benefits. You benefit from a healthier indoor climate because moisture and harmful substances are removed, which prevents mold. At the same time, you lose less heat, saving energy and increasing living comfort. Especially in well-insulated houses WTW is an ideal addition.

How does a heat recovery system work in an existing home?

A heat recovery system (WTW) extracts heat from the exhaust air and uses it to heat the incoming air. This keeps the temperature in the home stable without drafts or energy loss. The warm air from inside flows through a heat exchanger where the energy is transferred to fresh outside air. That warmed air is then distributed through ducts throughout the house. This reduces the need for heating and keeps air quality consistently high. The system works fully automatically, making it maintenance-friendly and energy-efficient.

Installing a heat exchanger in an existing home: where do you start?

Installing a WTW in an existing home requires careful preparation. The first step is to determine if your home is suitable. A well-insulated home with adequate space for ductwork is ideal. The installation consists of a central unit, air ducts, grilles and filters. Often the unit is placed in the attic or in a technical room.

Key points of interest are:

• Air duct space: in existing homes, ducts may need to be cleverly concealed in ceilings or cabinets.
• Proper air sealing: to prevent drafts and maintain efficiency.
• Sound insulation: modern systems are quiet, but proper placement prevents resonant noise.
• Professional installation: have a licensed installer calculate capacity and properly adjust the system for optimal performance.

With proper preparation, a WTW system can be installed within days, often without major remodeling.

What does it cost to replace mechanical ventilation with WTW?

The cost of WTW ventilation in an existing home depends on the type of home, the desired capacity and the complexity of the installation. On average, the costs are between €4,000 and €7,000, including installation. When existing ductwork can be reused, the costs are lower.

On the other hand, there are structural savings on energy bills as less heat is lost. In addition, subsidies are available through schemes such as the Sustainable Energy Investment Subsidy (ISDE). These can significantly reduce the total investment. An installer can calculate exactly what the best balance between cost and return is in your situation.

Questions about WTW ventilation installation in an existing home?

Want to know if your home is suitable for WTW ventilation and what it costs in your situation? Then contact the specialists at De Duurzame Jongens. During a no-obligation consultation, we discuss the possibilities, provide insight into the costs and advise on the most efficient approach. In this way you can turn your existing house into a comfortable and energy-efficient home.

1. Set to ‘Heat’ instead of ‘Auto’

It sounds logical to leave the air conditioner on Auto, but then the system may cool unnecessarily. By choosing Heat, your air conditioner focuses entirely on heating. That way you use the system optimally and your home feels more comfortable faster.

2. Keep the temperature realistic

A comfortable set point between 19 and 21°C is usually sufficient. Every degree higher costs up to 7% extra energy. By heating realistically, the indoor climate remains pleasant without unnecessarily high energy costs.

3. Use eco or economy mode

In mild cold, the eco mode is ideal. The system then uses less energy, but still provides a pleasant temperature. This saves costs and keeps your home comfortable, even during intermediate cold spells.

4. Clean the filters regularly

Clean filters improve air quality and efficiency. Dirt or dust obstructs airflow, causing your air conditioner to have to work harder. Clean the filters regularly or have this done at a maintenance service by The Durable Boys.

5. Check the outdoor unit

Leaves, twigs or debris can block the airflow. Make sure the outdoor unit remains free and have it checked by us if necessary. This will ensure optimal operation and prevent the system from consuming energy unnecessarily.

6. Close cracks and doors

Retaining heat starts with good insulation. Close doors to unused rooms and avoid drafts through gaps. That way the air conditioner won’t have to work as hard and your home will feel comfortable faster.

7. Deploy the fan smartly

A low, constant fan speed spreads heat evenly throughout your home. This prevents peak consumption and allows you to take full advantage of the heat generated.

8. Program with zones and timers

Heat only the rooms you use. With timers or zone settings, you decide when and where heat is needed. This saves energy and increases comfort: for example, warm bedrooms in the morning and warm living room in the evening.

9. Schedule annual maintenance

Regular maintenance keeps your air conditioner in top condition and extends its life. This keeps your system performing efficiently, preventing breakdowns and getting the maximum return on your investment.

Getting your air conditioner ready for fall

An air conditioner has long since ceased to be useful only in summer. With the right settings and proper maintenance, it can also heat efficiently in the fall. That means more comfort in your home, lower energy costs and less dependence on traditional heating. Would you like us to fall-ready your air conditioner? Contact us and schedule your appointment right away. That way, you can be sure your air conditioner is working optimally during the colder months and you’ll get the maximum benefit.

Why are my solar panels not providing power?

When solar panels stop providing power, it can have several causes. Sometimes it is due to temporary bad weather or an electrical grid failure. Often, however, something else is going on. Technical components such as the inverter or cabling play an important role in the functioning of the system. Dirt, shade or wear and tear can also significantly affect performance. It is therefore important to systematically identify the cause before taking action.

Common problems with solar panels listed

There are several reasons why solar panels don’t work properly. Below are the most common causes, with explanations and practical tips for recognizing and fixing them.

1. Contaminated or shaded solar panels

Dirt, dust, leaves or bird droppings can limit the light absorption of solar panels. Even a thin layer of dirt reduces yields, as less sunlight reaches the solar cells. Shadows from trees or dormers can also affect some of the panels, reducing overall efficiency. Clean your panels regularly and prune overhanging branches to avoid this problem.

2. A broken or malfunctioning inverter

The inverter is the heart of your solar panel system. This device converts the generated direct current into usable alternating current. When the inverter is broken or malfunctioning, you usually notice it immediately because the yield drops or disappears completely. Often an error message appears on the display or in the monitoring app. Check the status and reset the device if possible. If the error message persists, call in an installer to have the inverter tested.

3. Loose cables or poor contact in the connection

A loose contact or damaged cable can interrupt the power supply. Vibration, moisture or wear are common causes. Check regularly that connections are tight and visually inspect for wear or corrosion. Even a small interruption can result in a large loss of efficiency. Always have electrical connections checked by a professional to avoid risks.

4. Obsolete solar panels with reduced efficiency

Solar panels lose some of their efficiency over time. On average, efficiency decreases by about 0.5 percent annually. Older panels can therefore generate noticeably less energy than new ones. If you notice that production lags structurally, it is wise to have an inspection performed. A specialist can assess whether replacement is cost-effective, especially given the technological advances of modern panels.

5. Faulty microinverters or optimizers.

In systems with micro-inverters or optimizers, a failure in one component can affect multiple panels. These small devices ensure that each panel individually performs optimally. When one of them malfunctions, the power output of the linked panel or group of panels drops. Through the monitoring app, you can often see exactly which component is malfunctioning. An installer can replace the faulty part so the system is back to full power.

6. Poor installation or maintenance.

Improper installation or overdue maintenance is a common reason for problems with solar panels. Panels that are at the wrong angle or have inadequate ventilation produce less energy. In addition, poorly concealed wiring can lead to short circuits or malfunctions. Regular inspection and maintenance are essential to extend the life of the system and prevent failures.

How do I know if my solar panels are working as they should?

There are several ways to check if your solar panels are still functioning properly. The simplest way is through the inverter. On the display or in the app, you can see the current yield and any error messages. Also compare the monthly energy yield with previous periods or with your energy bill. A sudden drop may indicate a problem. In addition, check that all panels are clean and free of shade. Regular monitoring allows you to detect problems early and prevent them from growing.

Detecting faulty or broken solar panels: here’s how to do it

If you suspect one or more broken solar panels, you can investigate step by step.

1. First, check the inverter and note any error codes.
2. Then see in the monitoring app if there are any panels that are not providing power or less power.
3. Visually inspect for visible damage, dirt or loose cables.
4. If possible, use a multimeter or have an installer measure the voltage for each panel.

When in doubt, it is always wise to call in a certified installer. This will ensure that the problem is solved safely and professionally.

Hybrid solutions are available for many homes, allowing you to make a gradual switch.

3. Generate your own power with solar panels

With solar panels, you generate renewable electricity that directly contributes to lower energy costs. The investment usually pays for itself within a few years thanks to savings and possible feed-in compensation. When purchasing, pay attention to factors such as roof orientation, slope angle and panel type for optimal efficiency. Solar panels not only reduce your carbon emissions, but also make your home less dependent on fluctuating energy prices.

4. Future-proof your home with small habits

Increasing sustainability does not always have to be on a large scale. By making small adjustments in your daily behavior, you can save a lot of energy. Consider taking shorter showers, turning off appliances in standby mode or using a smart power strip. Even lowering the thermostat by one degree can make a noticeable difference on an annual basis. This is how you make sustainable living a natural part of your routine.

How can you make your home more sustainable without major remodeling?

Not everyone can or wants to invest in major measures right away. Fortunately, there are plenty of practical solutions that allow you to preserve without remodeling. Heat strips, radiator foil and crack sealing prevent heat loss. A smart thermostat helps to better regulate energy consumption. In addition, energy-saving habits, such as conscious ventilation or washing at lower temperatures, already make a visible difference. So you can become more sustainable step by step, with minimum effort and maximum impact.

You will receive a clear report with an estimate of the possible savings, so you can make choices with confidence.

There is also a comprehensive business energy scan for entrepreneurs and companies, which complies with specific energy legislation and targets larger properties.

Energy scan business: smart scan for business energy benefits

For businesses, an energy scan can make a significant difference in both cost control and sustainability. A business scan comprehensively maps out where energy is lost unnecessarily within the premises, such as lighting, climate control, production processes or outdated installations. In addition, the scan helps entrepreneurs comply with legal obligations, such as the energy savings obligation and the information obligation. The result is a clear report with concrete measures that lead to lower operational costs, improved efficiency and future-proof business operations.

A business energy scan also provides valuable insights for strategic choices. Think about determining investment priorities, preparing for sustainability projects or providing insight into subsidy opportunities. For many organizations, the scan forms the basis for a broader sustainability strategy that focuses on both financial and environmental gains.

What does an energy scan cost?

The cost of an energy scan varies by type of home or commercial building and the depth of the survey. For private homes, the price usually varies between 100 and 300 euros, depending on the scope of the inspection and the level of detail of the report. In some municipalities, energy scans are (partially) subsidized or even offered for free, making the investment extra attractive.

For business energy scans, the costs are higher because they are often more extensive and include multiple building parts, installations or processes. This should include amounts starting at around 400 euros, rising to several thousand euros in the case of large business complexes. In many cases, however, subsidy schemes are available, such as the EIA or other tax breaks, which can significantly reduce the investment. Thanks to this financial support, an energy scan usually pays for itself quickly.

How do you request an energy scan?

It sounds logical to wait, but it’s not. Right now, a home battery is a smart investment in your home. What’s more, you’ll be prepared. We explain why.

What is offsetting again?

When you have solar panels, you can offset power you feed back into the grid against power you later take back. This is called net metering. This makes solar panels attractive, but the scheme will be abolished after 2026. In the end, you will receive less for electricity you feed back.

Why a home battery offers benefits now

A battery allows you to use more of your own solar power directly. During the day, your panels often generate more than you use. Without a battery, that excess goes to the grid. With a battery, you store that power and use it at night or during cloudy times.

This provides immediate benefits:

• Less dependent on the energy grid: you use your own power whenever you want.
• Lower energy costs: purchasing less power during expensive peak hours.
• Better utilization of solar panels: less feed-in at low rates.
• Prepared for the future: later when net-metering stops, you are already prepared.

Calculation example

Suppose your solar panels generate 10 kWh on a sunny day and you use only 4 kWh during the day.

Without a battery, the remaining 6 kWh goes back to the grid. With a battery, you store that 6 kWh and use it later in the day.

The result is that you don’t have to buy extra power from the grid in the evening. That saves directly on your energy bill, even with net metering.

The real benefit? Independence

With a home battery, you take control of your energy use. You choose when to use your power, which gives peace of mind and less worry about rising prices or changes in regulations.

The statement “A home battery doesn’t make sense until net-metering stops” is a fable. Right now you already benefit from a battery, you use more of your own generated power and are less dependent on the grid. There is no need to wait. With a home battery, you save immediately and are prepared for the future.

Solar panels as roofing

Solar panels are no longer just flat structures that you simply install on top of your roof. In fact, today there are innovative products available that act as both roofing and solar power generators. These so-called “integrated solar panels” are specifically designed to replace traditional roof shingles or tiles. They offer a sleek design and are often less noticeable than traditional panels because they are subtly incorporated into the roof. In addition, they are a good solution if, for example, you fear bird nests under solar panels.

How does using solar panels as roofing materials work?

When you choose solar panels as roofing, you choose panels that are placed directly on the roof structure. So there is no intermediate roofing involved. The panels are designed to be waterproof while capturing solar energy and converting it into power for your home. They have special seals and joints to ensure that no leaks occur. This is similar to regular roofing so it works just as well.

Solar panels as roofing on barn

You may install solar panels on the roof of your barn. In most cases, this does not require a permit. However, it is wise to check with your neighbors beforehand so that they are not surprised. During installation, make sure that the panels do not protrude above the roof and that the roof of your shed is sturdy enough to support the weight.

In addition, it’s smart to check your municipality’s zoning ordinance. Sometimes it contains specific rules about what you may and may not modify outbuildings, such as a shed or garage.

In practice, a permit is often not necessary, but it is always good to check this via the Environment Counter. There you can use a quick online check to see if your situation might require an environmental permit after all.

Can you install solar panels as roofing on a carport?

Solar panels on a carport offer a smart and sustainable total solution. Not only do they generate clean energy, they function as a full-fledged roofing material at the same time. Instead of traditional materials such as bitumen, which are less environmentally friendly, the panels provide a tight, watertight finish. This way you make optimal use of the available space and reduce your dependence on fossil energy. The result: a carport that contributes both aesthetically and functionally to lower CO₂ emissions and a more sustainable living environment.

Advantages and disadvantages of solar panels as roofing materials

Choosing solar panels as roofing can have both advantages and disadvantages. In fact, installing solar panels is always a good idea. Nevertheless, in your situation it may be better to opt for regular solar panels, for example. Therefore, we have listed for you the biggest advantages and disadvantages of solar panels as roofing. Then you can make an informed choice yourself.

Advantages

Aesthetic design: solar panels as roofing offer a sleeker and more integrated look than traditional solar panels.

Space-saving: because they are placed directly on the roof structure, they make optimal use of the available space.

Sustainability: by choosing solar panels as roofing, you are contributing to a more sustainable world by generating green energy.

Cost savings: in the long run, these panels can lead to savings on energy bills. In addition, you will save the cost of laying roof tiles.

Increasing home value: homes with integrated solar panels may have a higher market value.

Cons

Initial cost: the purchase and installation of integrated solar panels may be more expensive than traditional panels. However, in the end, it will still save costs compared to regular power supplies.

Complexity of installation: replacing the entire roof can be more complex than simply adding solar panels on an existing roof. In new homes, on the other hand, it will be easier because the roof tiles do not need to be installed first. Do you already have solar panels but want to integrate them into your roof structure? Then beware, as there are costs associated with removing and replacing solar panels.

Maintenance: potential repairs can be more complicated, since you are dealing with both the roof and the solar panel.

Still relatively new: The technology is still relatively new, which can lead to minor problems or limited knowledge among installers. Therefore, look for the right professionals to help you with this.

Limited choice: fewer brands and models may be available compared to traditional solar panels.

5 tips for installing solar panels as roofing materials

Choose experienced installers

Installing solar panels as roofing requires specific knowledge. Therefore, it is essential to choose an installer with experience in this specific technology so that you can be assured of properly grounded solar panels. Look for the right professionals in the field of solar energy to ensure that the installation goes well.

Consider orientation and inclination

Make sure the roof is optimally positioned relative to the sun. The slope angle and orientation can affect the efficiency of the solar panels. So look into this before deciding where to have the solar panels installed. Read all about it here.

Integrate with a home battery

Consider adding a home battery to store the generated energy and use it when the sun is not shining. This home battery does cost extra and you won’t get a subsidy for it (yet). Ultimately, however, it will save you money. After all, you will always have enough power for your own household or still be able to quickly go into the Jacuzzi – which is also solar-powered – regardless of the weather or time of day.

Keep in mind local regulations

Check with your local municipality to see if specific rules or permits are required to install solar panels as roofing. This is because this is not always allowed everywhere and sometimes there are certain rules or conditions attached to it. So read up carefully before you opt for it!

Think about the future

Technology is evolving rapidly. Therefore, it is wise to choose a system that can be upgraded or expanded in the future. Get information from professionals about the possibilities. In addition, make sure you maintain the solar panels properly so that they last as long as possible. Then you can continue to enjoy the benefits in the future.

So solar panels as roofing are an innovative solution that offers aesthetic and functional benefits. As long as you educate yourself and see what is possible for your own home, you will be just fine. Good luck!
