Has anyone got montly performance figures for air source heap pump space heating 0-35 and hot water 7-55 degrees. see attached for analysis of heat pump versus LPG boiler solar combination tank hybrid. see attached

Hi A, how will allow for seasonal/low temp HP issues? I suppose that's why you want the data, but I guess much of it depends on it being linked to an external temp

I believe that there is a move to quoting heat pump performance in terms of Seasonal Performance Factor (SPF) rather the more ambiguous Coefficient of Performance (COP). I think there will be a new European Norm if agreement can be reached.

The UK website of one of the major Japanese car heat pump manufacturers has live and historical data from a number of referance sites which may prove helpful BP.

They (ASHP) should be tested to BS EN 14511: 2007. I havent got this norm, so I dont know what ambient temps are used, but its usually 7 degrees. I want to break it down to monthly COP's to see how th epump is performing in december and january.

Thanks Do-more, I havn't seen the data, can you PM me a link.
