What to consider
Heat pumps explained
Property suitability
Design starts with room-by-room heat loss, available space, emitters, hot water and the electricity supply.
Installation costs
A quotation should separate equipment, design, emitters, controls, electrical and building work, and any grant.
Running costs
Compare delivered heat, not only fuel unit prices. Seasonal efficiency and heat demand are important.
Alternatives
Compare a heat pump with boilers or oil heating on cost, comfort, emissions, disruption and practical constraints.
