Everything You Need To Know About Air Source Heat Pumps

An air source heat pump uses innovative technology that allows you to harness the air outside to heat your home. This means that not only can they save you money, but they are also completely renewable!

Read on to find out more about how air source heat pumps work, what kind of houses they can be fitted in, and how you can benefit from having an air source heat pump installed in your home. We’ll also tell you about a new government scheme that will allow you to get an air source heat pump installed at a fraction of the cost!

What is an air source heat pump?

Air source heat pumps are a completely renewable way of heating your home. They work by converting heat in the air outside your home, into heat inside your home!

They’re at their best in mild temperatures, but advances in technology mean that they can even work well in locations with sub freezing temperatures. Plus, they’ll still save energy!

Air source heat pumps can be used in conjunction with an efficient gas compressor boiler. This is known as a hybrid heat pump. The hybrid heat pump knows automatically what combination of energy will be best at any time. For example, it knows whether it will be more efficient to heat your home using the air, a combination of the air and the boiler, or solely the boiler. It always chooses the cheapest and most efficient option.

How does an air source heat pump work?

An air source heat pump works by extracting heat from the air outside, and converting it into energy that is used to heat your home or your hot water. The pump does this by using a compressor and two sets of copper coils (one inside your home and one outside). It works almost in the same way as your fridge does, only the opposite way round.

When using a hybrid heat pump, the system chooses the most efficient way to heat your home based on the temperature outside, and the current cost of gas and electricity. It will always choose the method to heat your home which is the most efficient, and the cheapest.

For a great explanation of how hybrid heat pumps work, you can watch this video by Daikin.

How much does an air source heat pump cost?

When considering the cost of an air source heat pump, you need to think about two things. First, the cost of the pump itself along with the installation. Then you need to think about how much the energy needed to run the pump will cost.

Hassle Free Boilers are currently able to offer installation of Hybrid Heat Pumps in conjunction with the Government’s Green Homes Grant. This means that you could get your hybrid heat pump and a brand new intergas boiler installed for as little as £2,500. That’s the same cost as a new boiler!

Your air source heat pump runs on electricity, but because they are extracting renewable heat from the air outside the heat output is more than the electricity input.

Can an air source heat pump replace an oil boiler?

In many cases it is possible to heat your home entirely using an air source heat pump, so yes, you could use one to replace your oil boiler.

Air source heat pumps heat at quite a low level, so where very hot water is required (eg. for things like doing the washing up) you may need to get an additional electrical heating element installed.

What type of home is an air source heat pump suited to?

Air Source Heat Pumps are usually either fitted to a wall or placed on the ground outside, so you will need to be sure that you have the space. If your home is a listed building you may need to get permission to have the pump installed.

It’s also worth noting that air source heat pumps are designed to heat consistently at a low level, so to be at maximum efficiency it’s important that your home is well insulated to keep the heat in.

What’s the difference between an air source heat pump and a hybrid?

The difference between an air source heat pump and a hybrid is that while an air source heat pump works as a standalone unit that is used to heat your home, the hybrid system also gives you the option of using a boiler or a combination of boiler and heat pump.

This is useful for times when factors like the temperature outside and the cost of electricity mean that to achieve the greatest level of efficiency, the pump could benefit from a little support from the boiler.

Benefits of an air source heat pump

The biggest benefit to getting an air source heat pump is that it will save you money. Air source heat pumps generate more renewable energy than it takes to run them, so you will be spending less on your energy bills. Not only this, but it means that you will be using less carbon, and doing your bit to save the planet. Find out even more ways of reducing your gas bills, in our handy guide.

Opting for a hybrid option is a great way to gain all the benefits of an air source heat pump, while still having a gas boiler as a back up. This means that you can be sure you are always heating your home in the cheapest and most efficient way.

Another reason to consider an air source heat pump is that the government has indicated that they are going to begin phasing out the installation of new gas boilers from 2025, in an effort to make the country more carbon neutral. It makes sense to opt for a lower carbon option for your home now, so that you can be prepared for this.

What is the cost saving of an Air Source Heat Pump?

According to the Energy Saving Trust you could save the following annual savings if you replaced your existing system with an Air Source heat pump:

  • Gas boiler = £400 to £465 saving when replaced
  • Oil boiler = £460 to £545 saving when replaced
  • Electric storage heaters = £800 to £990 saving when replaced
  • LPG boiler = £1,145 to £1,350 saving when replaced

Get an air source heat pump under the Government Green Homes Grant

The Government Green Homes Grant scheme has been extended to March 2022, and air source heat pumps are listed as primary measures under the scheme.

If you are eligible for the scheme (check eligibility) the government will pay up to £5,000 towards the cost of our renewable heating package (or up to £10,000 if you’re on benefits). Our package includes:

  • A top of the range Intergas condensing boiler.
  • Outdoor Smart Unit which allows the hybrid system to turn the air into heat.
  • Daikin Comfort and Altherma controller to control your new system.
  • 10yr Government backed HIES warranty.

All you’ll need to pay is £2,500, which is the same as the cost of a new boiler! You can even pay this using interest free credit at £68p/m. Get your renewable heating package now.
