Is the unit noisy?The Energy Saver has been optimised for quiet operation. The indoor unit's noise level is between 21 and 40 dB(A), measured one metre in front of and one metre below the unit. 21 dB (A) compares to slightly less than the noise you would hear in a theatre when nobody is talking, 40 dB (A) compares to a residential area at night.Do I need to maintain the unit?It is a good idea to regularly clean the air filter in the indoor unit, otherwise the efficiency of the unit with decrease. Full instructions are provided when you purchase the unit. Also see our maintenance page.How long will the unit last?We expect the unit to last approximately as long as a domestic fridge.Will the unit work when if the temperature drops below -5º C?This is an important question to ask when considering an air source heat pump (ASHP). The majority of ASHPs on the market have been designed for cooling or air conditioning purposes, and to be installed in climates with a relatively high ambient temperature. In such a location there would be little need to a) have an efficient heating capability, and b) design the unit so that it works at low temperatures. Non Energy Saver ASHPs are always designed to work down to an ambient of -5º C. The unit's electronic controls will shut down the unit to protect it when the temperature drops below -5º C. Further, the efficiency drops off very quickly once the temperature falls below + 7º C, with only 50 % of the total capacity at - 4 º C. With other words, non Energy Saver ASHPs do not provide sufficient heating when the heating is needed.In contrast, the EHS Energy saver retains 80 % of the total capacity at - 4 º C, and is certified to work down to minus 15º C, where it still retains 65-70 % of the total capacity.
