Air Source Heat Pump Installation - ASHP in Chelmsford (22)

Air source heat pumps are an alternative and sustainable way to keep your home warm. They work by taking heat from outside your home and transferring it to your central heating system.

Your air source heat pump will be made up of tubes filled with liquid refrigerant. Air from outside your home is blown over the tubes, increasing the heat of the refrigerant until it becomes a gas. Next, this gas goes into a compressor where the pressure increases. A heat exchanger is then used to transfer the heat from the refrigerant to the water in your home.

Once you’re sure installing an air source heat pump is the right choice for your home, it may help to know average costs. This should help you budget for this job. Before you can estimate the cost of a pump and installation, consider the following factors:

• Home insulation: Without proper insulation, you’ll need a stronger pump which will cost more.

• Size of your home: Larger homes require powerful, more expensive pumps.

• Efficiency of pump: More efficient pumps are more costly to buy.

• Brand: Different brands of air source heat pumps will cost different amounts.
