We will be installing an air source heat pump system as there is no gas in the village and replacing an oil boiler. I have had two quotes both specifying a 14kw heat pump. One supplier would only fit Daikin split system and the other is wanting to install Mitsubishi Ecodan monobloc. The price difference is 2k with the Daikin being more expensive. Is the Daikin worth the extra cost? Looking around at what the systems cost the installers are charging 3-4K to install and commission the system on top of what the heat pump and cylinder costs. (My builder will be doing the underfloor heating work). Is that going rate? Not sure if that’s excessive for 2 to 3 day’s work. I understand the cost will be more to get MCS certified so just checking that I am not overpaying. Any advice would be helpful.
