“Why does the floor need digging up?
You really have no idea what you're talking about.”
Heat pumps work best with ground source and underfloor heating that is expensive and disruptive to install in an existing house. It’s best suited to new build houses on a fairly large plot, smaller estate houses would use air source heat pumps which are much less efficient, in fact they have to use heater elements in very cold weather. If underfloor heating is not used then double the number of radiators are needed, in all cases a high level of insulation is needed.
So although Heat Pumps “can” be efficient and cheap to run, often they are not if they are not installed properly
Yes, I know they work most efficiently with underfloor heating systems. However, they're not essential.
There should be a high level of insulation with double glazing anyway.
In my post, I was referring to bringing a house up to EPC C level, for which a heat pump isn't even necessary. EPC C isn't that high.
It's a disgrace that landlords can make a profit from offering properties, which don't have efficient heating systems.to renters, who often have no choice.
