If you are either fitting your heat pump yourself or having it installed by a registered installer, you need to make sure that it is fitted in the correct location. Incorrect installation is one of the main reasons for heat pump failure.

If I’m honest, the vast majority of heat pump installations are normally carried out by a professional installer.

They will have the experience and expertise to ensure that your heat pump is fitted correctly.

There are however a small percentage of people who choose to install their heat pump themselves.

If you are one of these people, then it’s important that you take the time to research and understand where your heat pump needs to be located.

In this article, we will take a look at the important factors that you need to consider when choosing the location for your heat pump.

Where Is The Best Place To Put A Heat Pump?

A heat pump condenser is most effective when it is placed in a shaded area and not exposed to direct sunlight.

The condenser should also be positioned on the side or back of the house, out of the reach of trees or vegetation (which might obstruct airflow.)

If the heat pump is going to be installed on a rooftop, it’s important to make sure that there’s enough clearance for proper airflow and maintenance.

Other factors to consider when choosing the best location for your heat pump condenser include:

  • Noise level
  • Aesthetics
  • Accessibility

Noise level

If the outdoor unit is going to be installed near windows, bedrooms, or other areas where noise could be an issue, make sure to choose a model with a lower decibel rating.


Some people don’t like the look of heat pumps and prefer to keep them hidden from view. If this is a concern for you, make sure to choose a model that can be installed in a discreet location.


The unit will need to be accessible for maintenance and repairs, so make sure it’s not installed in a difficult-to-reach spot.

Once you’ve chosen the best location for your heat pump condenser, it’s important to have it installed by a professional.

Incorrect installation can lead to a number of problems, including decreased efficiency and increased noise levels.

There are Two Types of Domestic Heat Pumps

Best location for air source heat pumps

Ideally, an air source appliance should be placed in a space that isn’t too confined. For instance, one side of your home may have a tight alleyway, but the other side may be entirely parkland.

It would be better to position it on the garden side rather than in the narrow alleyway.

This is because the heat pump needs to take in large volumes of air in order to function properly.

If it’s placed in a confined space, the air will be restricted and this will limit the heat pump’s ability to work properly.

In addition, the heat pump should be placed in an area that gets plenty of sunlight. This is because the heat pump uses the sun’s energy to help heat the air that it takes in.

If the heat pump is placed in a shady area, it will have to work harder to heat the air and this will reduce its efficiency.

Best location for ground source heat pumps

When planning a GSHP, ground loops are the most popular option. The heat pump draws heat from the earth through collector pipes that are buried at a one meter depth and then released into your home.

The benefits of installing a GSHP are that they can provide an efficient and cost-effective solution for both domestic and commercial properties.

In addition, they can be used in a wide range of applications including underfloor heating, space heating, domestic hot water and cooling.

What Climates Do Heat Pumps Work Best?

Heat pumps are now used in temperatures far below freezing. Some heat pumps functioned better in cold weather prior to than others in the past.

However, owing to technological advancements, most heat pumps on the market nowadays can keep you and your family warm on even the iciest of winter days.


Do air-source heat pumps work at low temperatures?

While air-source heat pumps may function down to -20°C, they lose efficiency as soon as the temperature drops below 0°C. This is due to their reliance on natural air and the fact that as the temperature falls, the overall heat output of the pump falls.

Does geothermal work in extreme cold?

Yes, geothermal heat pumps can and do function effectively in cold winter environments. This is possible because while we have a significant rise in temperature above the earth’s surface a few feet below the surface, the temperature remains fairly constant.
This means that a geothermal heat pump can extract heat from the ground even when it’s freezing outside.

Are heat pumps best with underfloor heating?

Yes! Heat pumps are most efficient at lower temperatures, making this technology perfect for use with underfloor heating (UFH), which operates at a significantly lower flow temperature than radiators.

Can a heat pump be replaced without having to replace the air handler?

Yes, but there are some restrictions. You must ensure that the units you choose correspond to one another. It’s not enough to go shopping and pick out the first condenser you find in order to match it with your air conditioner.
It’s also important to get a unit that’s properly sized for your home. A unit that’s too big or small will not work as efficiently as one that’s the right size.
Finally, you need to make sure the new condenser is compatible with the air handler in your home. Not all units are compatible with all air handlers.

Can I use a heat pump with my existing furnace?

Yes, you can! However, you’ll need to get a professional to install it for you. Heat pumps are not “plug and play” devices. You’ll also need to make sure the units you have match appropriately and that the new condenser is compatible with the furnace in your home.
