They do seem to have a mixed reception .... couple up the road from us installed a heat pump (compulsory on their brand new build) ... after the first winter they had it pulled out and a boiler installed ... hard to know why some swear by them and some ditch them .... is it down to the competence of the installers a bit? .... we used to laugh when the renewables thing really kicked off .... there were people who were installing double glazing and garage doors suddenly re-inventing themselves as 'Renewable Enegy Experts' running about doing questionable installs all over the place. I wonder if heat pumps are suffering the same thing now they're flavour of the month.
