Yes! There are two main types of air source heat pumps, 'air-to-air' and 'air-to-water'. Most air source heat pump installations in the UK are what’s known as ‘air-to-water’ types.
'Air-to-water' air source heat pumps
Most air source heat pump installations in the UK are what’s known as ‘air-to-water’ types.In these systems, the heat is transferred into a conventional ‘wet’ heating system. And this set-up gives you hot water and central heating.
'Air-to-air air' source heat pumps
A minority of UK air source heat pumps are ‘air to air’. And, as their name suggests, these transfer the heat into the air, which is distributed around the home. They don’t provide hot water, though.
Hybrid air source heat pump
Because air source heat pumps give out less heat than a boiler, they’re not always suitable as a straightforward boiler replacement. Especially because there are still a lot of older, poorly insulated homes in the UK.
But heat pumps can often be combined with an existing central heating system and boiler. In these hybrid air-source heat pump systems, the heat pump provides a ‘base load’ for the day-to-day heating and hot water. With the boiler only firing up to provide hotter water. Or a quick heat boost during a particularly cold snap.
