A heat pump from The Sustainable Boys

Sustainable heating and cooling

A heat pump extracts heat from the outside air and converts it into comfortable heat for your home. The result is a pleasant indoor climate in winter and, with many systems, cooling in summer.

Our heat pumps are whisper quiet, compact and extremely efficient. They use 75% renewable energy. That means significant savings on your heating costs and much lower CO₂ emissions. In addition, you are ready for the future: more and more residential areas are (partially) switching from gas.

Do you combine a heat pump with solar panels? Then you heat largely with your own generated electricity and save extra on your energy costs.

Custom sustainability advice

Every home is different. That’s why we always start with a personal consultation in your home. Do you want to completely get rid of gas, or do you want a hybrid solution where the heat pump works together with your central heating boiler? We look at your home, consumption and future plans. This way you get a sustainability plan that really suits you.

Heat pump products

A heat pump comes in different types. Which type is suitable depends on your home, energy consumption and requirements. Whether you want to completely get rid of gas or opt for a hybrid solution, we will provide a heat pump system that fits.

Generating energy

All-electric heat pump

Completely off the gas

The all-electric heat pump completely replaces your central heating boiler. You heat and cool your home electrically and also provide hot water. The perfect match with solar panels and a home battery for maximum independence.
No more need for gas
Heating and cooling in one system
Ideal for well-insulated homes

Hybrid heat pump

The smart intermediate step

A hybrid heat pump works together with your central heating boiler. Most of the heat comes from the heat pump, for peak moments the boiler jumps in.
Up to 70% less gas consumption
Lower investment than fully electric
Ideal for less well-insulated homes

Measuring energy

Smart combining

With solar panels, you generate your own renewable electricity, which you can use directly for your heat pump. If you also choose a home battery, you will store this energy and use it at your convenience. That way you maximize the benefits.

Heat pump subsidy

A heat pump is an investment in sustainable comfort and a lower gas bill. Thanks to the Sustainable Energy and Energy Saving Investment Subsidy (ISDE), you also receive a substantial financial contribution from the government. This makes switching to a heat pump not only good for the climate, but also attractive for your wallet.

ISDE subsidy for homeowners

The Sustainable Energy Investment Subsidy (ISDE) is for homeowners who are going to make their homes more sustainable. Measures for which you receive a subsidy include insulation (glass, roof, floor, facade and walls), heat pumps and solar boilers. The subsidy amount depends on which measure and how many measures you implement.

02 Combining grants with funding

The ISDE can often be combined with financing options, such as:

– Energy Savings Loan from the National Warmth Fund – with low or even 0% interest (for income up to €60,000)
– Sustainable mortgage – extra borrowing space or interest rate discount when making your home more sustainable
– Municipal incentive loans – some municipalities offer additional financing In this way, you spread the costs, while immediately benefiting from lower energy costs.

Heat pump installation

The value of a heat pump is not only in its smart technology, but also in the way it is installed. Careful installation prevents malfunctions and guarantees years of efficiency. With The Sustainable Boys, you can count on craftsmanship, security and a system that works perfectly from day one.

Heat pump warranties

Investing in a heat pump is a big step toward a fossil-free future. A reliable installation and long-term warranty is indispensable. With The Sustainable Boys, you get the assurance that your system will last for years.

Product warranty heat pumps

Heat pumps typically have a 2 to 5-year product warranty from the manufacturer. Some brands (such as Vaillant or Daikin) offer the option of extending that warranty to 7 or even 10 years, often provided regular maintenance is performed by a licensed installer.

Installation Warranty

In addition to the product warranty, The Durable Boys gives you a 20-year warranty on installation. This ensures a safe and competent installation.

Product warranty optimizers

For systems with optimizers, you often benefit from longer warranty periods. For example, SolarEdge offers a 25-year warranty on their optimizers.

Power guarantee solar panels

Manufacturers guarantee that your panels will still provide at least 80-85% of their original output after 25 years. So you can be sure that the yield will remain at the same level.

Installation warranty on assembly

In addition to product warranties, The Durable Boys gives you a 20-year warranty on installation. This assures you of a safe and competent installation.

Service & maintenance

A heat pump runs intensively and requires regular checks. Proper maintenance extends the life, keeps efficiency high and prevents breakdowns. During a maintenance check we check refrigerant and pipes, filters and heat exchangers, fans, pumps and electronics, among other things.
– Hybrid heat pump: maintenance once every 2 years
– All-electric heat pump: annual maintenance recommended
– Service contract: automatically scheduled, so you have nothing to worry about

Heat pump costs

A heat pump provides immediate benefits: lower gas costs, increased comfort and a home ready for a fossil-free future. The final costs depend mainly on the type of heat pump (hybrid or all-electric). Thanks to the ISDE subsidy, you receive a substantial allowance, often between € 2,000 and € 4,000. This makes the investment immediately more attractive.

Generating energy

What affects costs?

The price of a heat pump system depends on a number of factors:
The system itself – the heat pump and necessary components
Installation – labor, materials and modifications to your home
Any extras – such as a boiler, buffer tank or underfloor heating

Frequently Asked Questions

Reviews

1. What is a heat pump and how does it work?

A heat pump uses energy from the air, soil or water, which is converted into heat (or cooling) via refrigerant and compression. This allows you to heat and/or cool your home in an energy-efficient manner.

2. What type of heat pump is right for my home?

It depends on your living situation, insulation, heating system and your wishes for the future. We assess your situation and recommend the right solution.

3. What does a heat pump cost including installation?

Costs vary by brand and type. With a hybrid heat pump, the costs are lower than with an all-electric system. We will be happy to calculate it for you in a quote.

4. How much will I save with a heat pump?

On average, you can reduce 50-70% of your gas consumption (or even become gas-free), depending on insulation, energy prices and system choice.

5. Does my home need insulation for a heat pump?

Good insulation helps tremendously: less heat loss makes the heat pump more efficient and cost-effective. In poorly insulated homes, a hybrid system may be a better fit.

6. Can I get a subsidy for a heat pump?

Yes, through the ISDE (Sustainable Energy Investment Subsidy) scheme you can receive thousands of euros back, depending on type, capacity and home.

7. Is maintenance mandatory and what does it cost?

Maintenance is often required to maintain warranty. Ask about our customized service contracts to get an idea of costs.

8. How long does a heat pump last?

With proper maintenance, a heat pump can function excellently for 15 to 20 years. Some components can last even longer.

9. Do I get a warranty on the heat pump and installation?

The product warranty is usually between 2-5 years (extending to 7-10 years is possible with maintenance), plus a 20-year installation warranty with The Sustainable Boys.

10. Can I combine the heat pump with solar panels?

Absolutely. You can use solar panels to power the heat pump, further reducing your energy costs.
