Looking over the Dakin range of heatpumps, the greater the output, the lower the energy star rating. A 6.2kw output unit receives 5 Stars, while the 9Kw unit only 1 Star.

Any idea why?

Thanks.............John in cold Mosgiel.

465344 2006-06-23 02:50:00 A bigger unit should be more efficient. ;) See if you can undersand the criteria (www.energystar.gov/ia/partners/prod_development/revisions/downloads/ac_ashp/Final_CAC_ASHP_Eligibility_Criteria.pdf). Graham L (2)
465345 2006-06-23 04:41:00 In theory heat pumps are meant to be the most efficient form of heating useing electricity. EG A 1kw bar heater only gives out 1kw of heat where a 1kw heat pump gives out 5kw of heat.
