Do I need planning permission for a heat pump installation?

In most cases, the installation of an air source heat pump on domestic premises is considered to be permitted development and doesn’t need planning permission, provided that:

  • It is used solely for heating purposes
  • The installation complies with the Microgeneration Certification Scheme
  • Is at least one metre from the property boundary
  • Is not within the curtilage of a Listed Building
  • Is the first installation of an air source heat pump at that property
  • Minimises its effect on the external appearance of the building
  • Installation is not on a pitched roof, within one metre of the external edge of a flat roof, installed on a wall fronting a highway if any part of that wall is above the level of the ground storey.
  • On land within a Conservation Area or World Heritage Site, it is not installed on a wall or roof which fronts a highway, or nearer to any highway than any part of the building.

 

Where is best to place the heat pump outdoor unit?

An air source heat pump sometimes has an indoor unit and always an outdoor unit. The outdoor unit is a rectangular case of approximately 90cm high x 150cm wide x 20cm deep. So where’s best to place it? In the garden? Next to your house? An outdoor unit works best and delivers the best efficiency if it is placed against a wall. Not directly against it, but about 20 cm from it and at least 20cm from the ground. We recommend a height of 30cm, so that you never have problems with snowfall. The space around the outdoor unit, and in particular at the front, must be free (by approximately 1 metre). If a path passes by, bear in mind that the area at the front of the outdoor unit can become damp and can therefore become slippery. We do not recommend placing cupboards or other types of enclosure over the outdoor unit. The reason for this is that it may limit the air flow and then the system cannot run optimally. Ice can also form on the cabinet or fencing in winter, which also disrupts the air currents. Preferably do not place the outdoor unit on a wooden roofs or roofs, as this can cause vibrations. It is also not recommended to position it under a bedroom window. Although the heat pump is silent, it will sometimes have to thaw in the winter and that may make it noisier than usual.

Why a heat pump?

 

Why a heat pump?

Good for the environment and for your wallet

Heating your house with a gas boiler is not ideal in the long term. The UK government is banning gas boilers in all new homes from 2025. Why? Because it is good for the environment, because gas is a fossil fuel that runs out slowly. The use of gas also causes considerable CO2 emissions. And the UK has committed to net zero gas emissions by 2050. For these reasons, gas-fired central heating boilers will be phased out in the longer term and other forms of home heating are becoming more relevant.

When a heat pump is used, the house is heated with energy from the air or soil, and electricity is used instead of gas. Note: you do not have to get rid of your boiler immediately. Indeed, there are also hybrid forms of heating that use a heat pump and gas boiler in combination. As a result, you also use much less gas. It’s nice first step on the way to gasless heating. In addition to contributing to the environment, sustainable heating also provides you with financial savings. Electricity is used in a more efficient way to heat your home instead of your gas-fired boiler. You use less gas and more electricity and, depending on your current heating system, your energy bill is likely to go down.

What is a heat pump?

A heat pump heats your home and provides hot water.

The heat pump installation replaces your boiler and can be connected to the central heating system. By extracting heat from the air, ground, or water source, the installation produces renewable energy. So you can enjoy sustainable heating! Electricity is required to make a heat pump work, so your use of electricity increases. However, gas consumption decreases considerably or even drops to zero. This reduces the CO2 emissions for heating the home.

How can I save energy with a heat pump?

With an all-electric heat pump, you no longer need to use gas for heating your home, and with a hybrid heat pump you reduce gas consumption by up to 80%. It is not for nothing that a heat pump is seen as the starting point for making your home more sustainable.

Find out all about heat pumps and how much you could save on your energy bills.

How does a heat pump reduce my CO₂ emissions?

The heat pump uses energy from the air, ground or water source and electricity to heat a home. Heating a home with gas causes the greenhouse gas CO₂ to enter the atmosphere, which causes global warming. With a heat pump, the house is (for a large part) heated with renewable energy and you use less or no gas - and thus reduce your CO₂ emissions.

 

Is a heat pump new technology?

No actually! Daikin launched the first heat pump into the market in 1957. In the residential sector, more than 400,000 Daikin Altherma heat pumps have been fitted across Europe since their initial launch in 2006.

All heat pumps are essentially based on the technology of the refrigerator in reverse and involve the transfer of heat. Heat pump technology has also been used in air conditioning for many years. 

What types of heat pumps are there?


Depending on the heat source, the heat pump can look different in practice. There is almost always an indoor unit. This often does not look much different than a typical boiler and certain types can be hung on the wall, just like a boiler. The five most common types of heat pumps are:

• Air / water heat pump
• Water / water heat pump
• Bottom / water heat pump
• Hybrid heat pump
Air-to-air, air-to-water and hybrid heat pumps use air as an energy source. The water-to-water and ground-water heat pumps are installed underground: through a system in the ground, heat from a natural water source or the ground itself is used as an energy source for heating the house. Read more about these types of heat pumps.

Do I have to turn my entire garden upside down when installing a heat pump?

There are different types of heat pumps. Air-to-air, air-to-water and hybrid heat pumps use air as an energy source. These types of heat pumps do not require digging into the ground. Only the water-to-water and ground-water heat pumps are installed underground. Through a system in the ground, heat from a natural water source or the ground itself is used as an energy source for heating the house. These type of systems require much greater installation work in your garden than an air source heat pump. Read more about these types of heat pumps.

Where can I buy a heat pump?

For the right heat pump, you need customised advice based on your individual circumstances.

There are several different types of heat pumps. Which type is suitable for you depends on the situation in your home and your wishes and requirements. That is why it is wise to research the possibilities thoroughly before purchasing and to request customised advice. This is possible, for example, with an installer or manufacturer, but also with an independent energy advisor.

To be able to do its job properly and efficiently, the heat pump must be correctly aligned with the other components of your heating system. That is why it is important that your installer knows what they are doing. In most cases, the installation of an air source heat pump takes a day at most. For a ground source heat pump, a borehole has to be drilled into the ground, so the process is more complex and more time is needed.

What does a heat pump cost?

In the long term, heat pumps are often cheaper than high-efficiency boilers.

Heat pumps are more expensive to purchase than high-efficiency boilers. But if the installation is well designed, the energy consumption is considerably lower. That is why a heat pump is often cheaper in the long run. The price of a heat pump installation is not easy to calculate, because it depends on the situation in your home and your wishes with regard to comfort (which areas must always be warm and how much hot tap water is needed). The table below shows target prices for the most important heat pump systems for UK homes.

Type of heat pump Price including install Funding
Ground source heat pump vanaf ca. €12.000 €2.500,- of meer
Air source heat pump €5.000 – €10.000 €1.100,- of meer
Hybrid heat pump €4.000 – €7.000 €1.100,- of meer

FAQs

Is every heat pump suitable for my home?

You need to find out in advance which system best suits your home. Not every type fits every situation. This depends, among other things, on the type of house (terraced house, apartment, new construction), the insulation, the space for the system (both inside and possibly outside) and whether or not there is a ventilation system.

I have just had a new boiler fitted. Can this be used with a heat pump?

A heat pump can be added to an existing central heating boiler.

By adding a heat pump to an existing central heating boiler, a bivalent system is created and considerable savings can be made on gas consumption. With bivalent systems, the user often has to determine whether heating is carried out by the central heating system or by the heat pump, and it is also possible to do this on the basis of outside temperature.

Do I have to insulate my house more?

The better your house is insulated, the better the result.

Without good insulation and low temperature heating, an all-electric heat pump is not efficient. You then have to buy a large heat pump and in many cases the installation will not work optimally. Fewer structural adjustments are required for a hybrid heat pump. But in all cases the following applies: the better a house is insulated and the lower the temperature in your heating system required to heat your house, the higher the efficiency of the pump.

Which heating delivery system do I need?

A heat pump ensures a constant temperature, both during the day and at night. A hybrid system will work effectively with the existing radiators. If you opt for an all-electric variant, you will need either underfloor heating or low temperature radiators.

 

A heat pump ensures a constant temperature, both during the day and at night. With a hybrid you can suffice with the existing radiators. If you opt for an all-electric variant, you will need either wall or floor heating or low temperature radiators.

Does a heat pump add value to my house?

Less energy consumption changes the energy label of your home, so the value of your property could improve!

Because a heat pump uses less energy than a boiler, the energy rating of your home changes. And this could also increase the value of the home.

Is an expert always needed when installing a heat pump?

Not everyone can install a heat pump, as it requires specialist knowledge and expertise from an installer. A poorly designed and commissioned heat pump system may still use a lot of electricity. In addition, if you are seeking funding from the Renewable Heat Incentive for your heat pump, the installation will need to have MCS accreditation, so it's important to work with a suitably qualified and trained installer.

Not everyone can and may install a heat pump. This requires knowledge and expertise from the installer. A poorly tuned heat pump still uses a lot of electricity. In addition, most heat pumps require certification from the installer.

Does a heat pump take up a lot of space?

A heat pump indoor unit takes up a little more space than a traditional central heating boiler. If you opt for an all-electric variant, then a water cylinder must be installed next to the heat pump for hot tap water (for showering, baths etc). Moreover, with an outside air heat pump there is always an outside part that takes up around 1 m².

 

Does a heat pump make a lot of noise?

Daikin staat in de markt bekend als producent van de stilste airco ter wereld.

De buitenunit van een warmtepomp op buitenlucht heeft naast een ventilator en een compressor. Beide produceren geluid. Vanuit de airconditioning-wereld is er echter al veel ervaring opgedaan om deze geluidsbronnen zo goed mogelijk te isoleren. Daikin is hier goed in. In de praktijk is er dan ook geen sprake van 'herrie'. Ja, een buitendeel maakt geluid, een zoemend geluid. Net als een koelkast dat doet. En als de warmtepomp erg hard moet werken (bijvoorbeeld bij koude of grote warmtevraag), dan hoor je hem beter. Maar het stoort niet en is niet hoorbaar in de mix van andere geluiden in en om het huis. De plaatsing van een buitendeel verdient wel aandacht. Bij voorkeur dan ook niet onder je slaapkamerraam.  Daikin staat in de markt bekend als producten van de stilste airco ter wereld, daarnaast zijn de buitendelen compact en op vele manier weg te werken.

Does a heat pump require a lot of maintenance?

A heat pump is not maintenance-free, but it is low in maintenance. Maintenance of a heat pump is preventive and takes place on average once every two years.

Can a heat pump provide cooling?

With most heat pumps, with the exception of ventilation heat pumps, you can also cool.

With this you increase the comfort at home in the summer. There are two different ways of cooling, active and passive. Passive cooling is possible by means of a ground-based heat pump, whereby use is made of the cold in the soil which is pumped through the system through a circulation pump. For active cooling, a compressor is needed, the heat is released to the outside air via the air conditioning principle.
