Who is this for?

This guide is specifically for tradespeople. It covers what you need to do before and during installation.

Heat Pump (1)

Advantages of a heat pump installation

  • Cheaper to run than oil and gas boilers
  • Reduce carbon emissions by using renewable heat from the air or ground
  • Highly efficient conversion rate of energy to heat
  • Options for cooling during the summer, making it an air conditioner

Step 1 - Choosing the right system for the property

How well a property is insulated plays an important role in the size of heat pump you select and how efficient it's going to be as, compared to a gas or oil boiler, heat pumps produce heat at a lower but more constant temperature. Things to consider include:

  • Cavity/wall insulation
  • Loft insulation
  • Double glazing

Also look at how well floors are insulated if you're dealing with a much older house.

If insulation or the age of the property is a concern, choose a hybrid system; this combines a heat pump with a small electric boiler to give a higher heat output.

Step 2 - Complete an Electricity Supply Enquiry (ESE) form

Complete the ESE form to ensure the home's electricity service and local network can accept the additional load. This important step protects you and your customer!

The ESE form is an editable PDF. You can complete it using a computer, or print it and fill it out by hand.

Step 7 - Installation

Air source heat pumps are usually positioned on the ground. They include an outdoor unit (the heat pump) and an indoor module connected to your heating system

Firstly, you need a suitable place to place the outdoor unit with reasonable clearance around it. This ideally needs to be sheltered from the elements and safe from tampering by passers-by.

Once both units are fitted on to their mountings, water or refrigerant and drain hose pipes are connected and insulated, inside and out. You can then connect the heat pump to the indoor heating system.

Step 8 - After installation

We recommend an annual inspection of air source heat pump and controls.
