Heating comparisons

Heat pump comparisons, without the marketing spin.

Heat pumps are not always the right answer. These comparisons tell you when they win, when they tie, and when a different system still makes sense.

The decision facing 23 million UK homes. We model install, running and 10-year totals — and tell you when a boiler still wins.

Off-grid homes save the most. With BUS, payback against oil typically lands in 4–8 years.

Combi-to-heat-pump means a hot water cylinder — and that needs space. Here's when it works and when it doesn't.

Higher efficiency vs lower install cost. We do the maths on whether the upgrade is worth it for your property.

They are not alternatives — they are complements. Modelling combined install cost and payback.

A heat pump IS air conditioning, in reverse. Why this matters when comparing US-sold and UK-sold systems.
