Heat pumps: 7 top tips for installers
Posted by Cathy Debenham on 22 September 2010 at 9:08 am
"Many heat pumps appeared to be installed incorrectly." reports the Energy Saving Trust in its recent report on field trials into 83 installations of air source and ground source heat pumps. This is disheartening news, and we thoroughly endorse its recommendation that guidance to, and training of, installers is reviewed. In the meantime here are its seven top tips for installers:
1. Keep the design of the installation simple. The research found that the simplest system designs achieve the best efficiencies.
2. Keep controls simple. It is vital that the customer can understand how to use them.
3. System sizing is key. Ensure the system is sized correctly to meet the property’s central heating demand.
4. Be transparent with customers. Discuss system running costs, and the likely performance, as frankly and honestly as possible, so their expectations are realistic.
5. Advise your customers about the need for any supplementary heating.
6. Be aware of the margin of error. If a heat pump is installed even slightly wrong, the outcome for the customer may be very wrong.
7. Manage your subcontractors rigorously, to make sure their work is appropriate for your heat pump. You need to take responsibility and supervise each stage of the installation.
