A/W Heat Pump Recommissioning/Optimising

    There are plenty of stories of early adapters of A/W heat pumps negatively affected by poor design/install/commissioning/workmanship. I was wondering if there suppliers (North leinster preferable) that will review a system design and recommission a system, if required, to optimise performance. I expect this would come with a few caveats attached as some reasonable assumptions would be made around emmitters etc. However with electricity prices over the past 12months some may have looked closer into this.

    I looking at this as a prospective buyer of a 18yr old house that had a Daikin Altherma installed in 2013 to replace a OFCH. UF heating installed during construction. Unfortunatley there are zero records available of the system design and commissioning.

    In an ideal world something that would satisfy BER requirements would be great but aware of the challenges with that.

    I’m looking to have a heat pump retrofitted in the same area and it is very difficult to find companies who have the time to do it, the building trade is just so busy at the moment and renewable energy stuff even moreso. I’d guess recommissioning an existing system where they won’t make anything selling kit and are being asked to stand over work they didn’t do, even with caveats issued.

    What I would say though is that there’s no rocket science to much of this, if you have the time and interest to spend time learning about it I’d say you can figure it out yourself. This has the added benefit that you will be living in the house so can see day-to-day what’s happening and how you like the house.

    I could be wrong but I don’t think you need to do anything to satisfy a BER survey, they’ll just look at the unit and stick the spec into their spreadsheet. What they do need some info on is the insulation put in the floor under the UFH, which unfortunately a heatpump engineer cannot help with anyway.
