Heat pumps can pretty much be installed to any house as long as there is enough space outside for the compressor and a source of power.

The main thing to consider when installing a heat pump is the size of the unit itself.

One of the great things about installing a heat pump is that it can save you money on your energy bills.

A properly sized and installed heat pump can save you up to 40-50% on your energy costs.

That’s a huge saving!

Another benefit of heat pumps is that they are very efficient. They use less energy than traditional heating and cooling systems, which means they have a smaller carbon footprint.

Heat pumps also have a longer lifespan than HVAC systems, so you won’t have to replace them as often.

In this article, we’ll discuss the installation of heat pumps in old houses specifically. We’ll go over some of the benefits and some of the challenges that you may face.

Installing A Heat Pump In An Existing Home

If you are thinking of having a heat pump retrofitted into an existing home, there are a few things you should know.

First, it is important to have a professional assess your home to see if it is a good candidate for a heat pump installation.

There are a few factors that will be taken into consideration, such as:

  • The size of your home
  • The climate you live in
  • And, the type of heating and cooling system you currently have.

Once it has been determined that your home is a good candidate for a heat pump installation, the next step is to choose the right heat pump for your needs.

There are many different types and sizes of heat pumps on the market, so it is important to do your research to find the best one for your home.

Air source heat pump in an old house

You can install a air source heat pump in an old home, but one of the first things to consider is how well insulated your home is.

The better insulated your home is, the easier it will be to heat and cool with a heat pump. If your home is poorly insulated, you may want to consider having some insulation installed before you have a heat pump installed.

Another thing to consider is the type of heating and cooling system you currently have.

If you have an electric furnace, for example, you will likely need to upgrade your electrical service in order to accommodate the new heat pump.

You should also have your ductwork checked to make sure it is in good condition and that there are no leaks.

Leaky ductwork can cause your heat pump to work harder than it needs to, which will decrease its efficiency.

Ground source heat pump in an old house

You can install a ground source heat pump in an old home, but one of the things to consider is the size of your property.

The ground source heat pump needs space to install the underground piping, so if you have a small garden, it may not be feasible.

One final thing to keep in mind is that ground source heat pumps are more expensive to install than air-source heat pumps.

Do you feel you will be getting a good return on your investment?

That is something you will need to decide for yourself.

Best Heating System For An Old House

You probably guessed it? An air-source heat pump is the best heating system for an old home.

Not only are they more efficient than traditional heating systems, but they also have a longer lifespan.

Air source heat pumps are also less expensive to operate than other types of heating systems.

If you live in a climate that is not too cold, an air source heat pump may be all you need to keep your home comfortable all winter long.

Do Heat Pumps Work With Old Radiators?

If you’re going to the trouble to install a brand new heat pump system in an old home, you’re probably wondering if it will work with your existing radiators.

The answer is, yes! Heat pumps are designed to work with all types of heating systems, including radiators.

In many situations, existing radiators are capable of dissipating a greater quantity of heat than standard designs.

For example, if the energy efficiency of the building envelope is improved at the same time, existing radiators may be larger enough to accept a lower flow temperature.

In other words, your old radiators can probably be used with a heat pump, but you may need to have them replaced or upgraded if they are not large enough to work with the lower flow temperature of the heat pump.

When retrofitting an old home with a heat pump, it is always best to consult with a professional to ensure that your home is a good candidate for the installation and that you choose the right type of heat pump for your needs.


Should I get a heat pump?

If you have the budget and space for it, a heat pump can be a great addition to your home. They are more efficient than traditional heating systems and have a longer lifespan.
Can I install a heat pump myself?
Unless you are a professional, we recommend that you consult with one before attempting to install a heat pump yourself.

Can you put underfloor heating in an old house?

Yes, underfloor heating can be installed in both new and old homes. However, you may need to make some modifications to your home in order to accommodate the new heating system.

Can you fit underfloor heating in an old stone house?

Yes, as long as the house is not listed and the vast majority of the flooring is not original stone flags, you should be able to install underfloor heating. If you do, you would need to lift the flags and relay

Can heat pumps use existing pipes?

No, you can not use existing pipes. You will need to have new ones installed by a professional. Unless we are talking about the pipes connected to your existing radiators, in which case, they might be able to be used.

Can you install a heat pump in a flat?

Yes, you can install a heat pump in a flat. It would need to be an air source heat pump and you would need enough external space to install it.
