Domestic Heat Pump Selector

Follow the simple step by step guide below to select your heat pump.

Disclaimer: Please note that this tool is not intended to replace a full heat loss survey and must not be relied upon for any final determination of your heating or hot water requirements or final design of your heat pump system.

Please note that from April 2022 the RHI will be replaced by the Boiler Upgrade Scheme which will offer an upfront subsidy of £5000 to qualifying Air Source Heat Pump installations.

To confirm suitability of the selected equipment it is strongly recommended that a site survey is carried out by ourselves to advise on any improvements to the existing heating and hot water system such as (but not limited to) pipework and radiator upgrades and/or additional insulation works for the efficient operation of the system. There are instances where a heat pump is not the most cost effective solution in terms of installation and ongoing running costs. We will make this clear to you if this is the case.

To generate a formal quotation will require a site survey to determine the heat loss of the property, including a room by room heat loss calculation to determine suitability of existing heat emitters and any necessary modifications. We charge £250 + VAT to carry out the survey which includes the full heat loss calculation and system design. This amount is deducted from the quotation should you decide to proceed.

1 Any costs are merely indicative and are based on a basic installation where minimal modification to the existing heating and hot water system is required. Any prices listed do not represent an offer by Heidi Air Conditioning Ltd to sell you or provide you with any goods or services.

2 Eligibility requirements for the Boiler Upgrade Scheme are as follows:

- the maximum allowable capacity for the heat pump system cannot exceed 45kWth.
- commissioning date for all systems must be after 1st April 2022.
- systems must meet the full heating and hot water requirements of the property.
- heat pumps must be MCS approved.
- installation must be new and for the replacement of a fossil fuel boiler or direct electric heating.
- any EPC recommendations for loft or cavity wall insulation must be fulfilled and evidenced with a new EPC.
