Are air source heat pumps always the best use of the budget in a modern, low heat loss home?
Their efficiency is not in question. But when heat demand is already low, the real issue becomes whether the extra capital cost delivers enough saving to justify it.
In our latest article, we compare an ASHP with an EHS Heat Only electric boiler over 15 years and ask a different question:
What if some of that capital was invested elsewhere in the home instead?
We look at:
* installed cost
* servicing and parts
* solar PV
* waste water heat recovery
* hot water cylinder sizing
* the point at which ASHP efficiency starts to win financially
The result is not an argument against heat pumps.
It is a reminder that the best-performing home is not always the one with the most efficient individual appliance.
For low heat loss properties, system design and capital allocation matter.
