10 years ago i installed this unloved Daikin air source heat pump. 4 bedroom semi detached. 7kw so got the sizing about spot on with no wizardry heat loss software. The unit not missed a beat apart from the electrical isolator filling with water within 6 months because the electrician didn’t seal the box (one job!) Just needs the fan coil cleaning, expansion vessel recharge and check the settings.
