What Heat Pump Have You Got? The RHH Members' Roll Call
With more and more members joining Renewable Heating Hub, I'm finding it increasingly difficult to remember who's running which heat pump, particularly when we're discussing particular brands, models or troubleshooting problems.
So I've put together this running list of members' heat pumps, organised alphabetically by manufacturer. The idea is to make it easier to find other homeowners with the same or similar equipment, compare experiences and share advice.
If your heat pump isn't listed, please reply with your username, manufacturer, model and capacity in kW. Feel free to include any additional details you think might be useful, such as your controller, cylinder or whether you're running multiple units.
I'll add your details to the main list and remove your original reply to keep everything organised. Equally, if I've got your details wrong or you've changed your heat pump, please let me know.

Hopefully this will become a useful reference for everyone, particularly when we're comparing performance, troubleshooting problems or looking for somebody with experience of a particular system.

Wouldn’t you also need the heat loss estimate for the house, or the W/m2, to take into account the construction/insulation?
If Homeowners are prepared to provide the information, then maybe a spreadsheet containing the following information would be of most use from the comparison, and highlighting of possible problems, point of view.

Am I the only person here with a cascade system?
I think you might be. How much energy do you use when it's cold, i.e. as in mid-December? Have you got near your 16.5kW design power?
03/01/2023 9:06 am
@kev-m Hi Kev. Not sure how to calculate that. In the cold week at the start of December (0 to -8 C all week) the HP system drew an average of 70 KWh per day peaking at 105 KWh. The house was reasonably warm all that time and I did not have the sense that the ASHP were near their limit to supply energy (though some rads should probably be upgraded) One of the issues I have is that there does not seem to be a measure of output energy in this system. The standard Ecodan system does show output but apparently the cascade does not!
03/01/2023 10:38 am
I didn't know the cascade system didn't give you the numbers. 105kWh at a COP of 2.5 (what I got in the cold snap) is a constant 11kW (105*2.5/24) over 24 hours.
What flow temp are you using?
03/01/2023 7:10 pm
Ok So here is where I need a better manual. The Summary Settings screen says 45C. Melcloud says the flow temperature is 50C when the room thermo is calling for 20C (actual 18.5), but then drops to 42 When thermo at 18C (actual 18) and 25 when the thermo at 16 (actual dropping towards 17).
If I try to get to the point to set the flow temperature by working my way through the screens on the controller I get to a point when the controller asks if I want to shut the system down. Should I say yes at this point?
