@ntruby  ok, first to explain the 61deg......eddie will either heat up the immerser until his temperature sensor tells him to stop.....or until the immerser thermal cutout switch cuts it out so either the immerser or eddie has a cut off temp of circa 61deg. This is independent of the heatpump.

 

To check if you are actually able to heat the water in the cylinder using the heatpump you can do the following:

Check the DHW temp on the screen if it is lets say under 40 then the DHW should be heating. Check by following my previous suggestion:

You can also check the status from the front screen by doing the following:

Press the gear button and navigate to operation status.

You would expect to see compressor highlighted in blue to show it's operating and also the water pump in blue. The booster heater should be greyed out as it shouldn't be on.

If the temperature isn't low enough to trigger it to be heating the water you could manually raise the set temperature to encourage it into action, but remember to set it back down later 🙂

Just found a snippet in the Freedom heatpumps documentation which seems to say the hysteresis is set to 7deg so that ties up with your original figure of 50deg set temp falling to 43deg. If you can confirm that your heatpump is actually doing the DHW I think your system might be fine.

Just to check, I take it that you are putting much less cold water in when you are filling the bath? It's kind of a habit to put on both taps at the same time when you have a gas boiler as the water is that much hotter, but with the heatpump water being lower temp you need much less cold water. Sorry if i'm stating the obvious.

@derekdeleon OK right now the water temp is 53.5 and I can't set the desired temp above 60C, so I have reduced it to 45C and will test it out in the morning.

The bath has a mixer tap so I don't think that adding too much cold is the issue.

Thanks!

Thank you Derek and Gary: this has been so interesting and informative!  If only my supplier could have left some simple instructions.

The heat pump is definitely heating the water.   Field setting 3023 is 5C, so I am still not sure how the temp got down to 44C.

If the temp is too low what can I do to force the heat pump to kick in please?
