Air-source heat pump refers to one type of heat pump that is designed to extract heat from the air outside and convert as energy. Even if the temperature is cold, heat extraction is possible. This eco heating uses the external air to heat water in the hot water tank or radiators.

Unlike the gas-fired boiler that produce hot water, this eco heating require you to keep your living space warm enough by running the system longer. Besides, you also need to increase or adjust the size of the radiators.

You may find the heating fans a bit noisy. The eco heat pump tend to be busiest during winter since the weather is cold and you want to stay inside most of the time.

Cost of Air Source Heat Pumps

If you plan to get an air source heat pump installation as your eco heat source, then you should budget anywhere from around £7,000 to £15,000 plus depending on the size of your property and size of the area that needs to be heated. This heat source system will help you save approximately ₤500-£1000 per year or more, depending on the supplier.

Air Source Heat Pumps Pros:

  • An air source heat pump uses about 1 unit of electricity in producing 3 units of heat
  • when installed right, this heating system is dependable and provides efficient heating results.
  • This eco heat system uses less fuel to heat your living space.
  • You can take advantage of various government grants.

Air Source Heat Pumps Cons:

  • Some air source heat pumps can get noisy due to the fan heater but recent models are always getting quieter
  • Some require long hours of operation during winter months.
  • Heat pump systems may require you to install bigger radiators.

As you try to use solar panels and heat storage battery system, you can produce your own energy and heat source and then store the excess energy. So, during peak periods, you have energy to use.

You can heat storage battery system to produce instant hot water for your baths, showers, and radiators. When the carbon intensity or price of electricity is low, you are free to use the solar panels and heat batteries.

Solar and Heat Battery Storage System Pros:

Using solar panels, you can use renewable energy and it has no impact to the environment (apart from their initial manufacture). You can also save on monthly bills. As for the heat batteries, they are compact and more efficient at storing heat compared to a hot water tank.

Solar and Heat Battery Storage System Cons:

Installation of solar panels and heat storage systems comes with high upfront cost. Not only that, solar panels are dependent on daylight (not necessarily weather), requires space, and you cannot take it with you should you need to move house.

We cover the advantages and disadvantages of solar energy in more detail in a separate post.

Spray Foam Insulation

Since 1986, spray foam insulation has been available to many homeowners. This eco heat retention system is widely used due to its energy efficiency and heat retaining benefits. You should have less issues with heat loss if you have adequate insulation.

With high quality spray foam insulation, rest assured that you can save from your utility expenses while eliminating retrofit crawl spaces and make your living space feel more like a home.

The way this eco heat system product works is by creating limited air movement, which means the amount of energy loss is being reduced.

Spray Foam Insulation Pros :

While you need to invest in high quality external-wall insulation, windows, and doors, spray foam insulation can cut your heat and energy bills in the long run.

With this kind of eco solution, you can enjoy an extra “layer” of comfort at home.

Spray Foam Insulation Cons:

Getting a spray foam insulation means you may need to deal with a large upfront cost. Other than that, you can also encounter mess and disruption. To minimize internal-wall insulation issues, you should ideally get it done room by room during the renovation or decoration process.

We created a more detailed guide looking at the pros and cons of spray foam insulation and how it compares to other types of insulation.

German Electric Heaters
