Yes that can be done, but why do it? If you want a pint jug of water at 40 degrees C, there's no need to boil a kettle, and then dilute the 100 degree...
Welcome to the forum! This is getting too hot - you might end up cooking one of the nippers (if they are nippers). The showers might be OK - unti...
@transparent - here's the page with more details and images on what my heat pump has.
@transparent - I summarised the results here. What we actually found were wiring diagrams showing the PWM control cable (in addition to the power cabl...

If you know when it will go into DHW heating mode (because it is on a timer?) then it won't take much to get useful readings, say flow rate, LWT/RWT (...
There is also enough info there to calculate calculate power output, which is LWT/RWT delta t x flow rate/3.6 x circulating fluid specific heat (the d...
If you get this in time, can you do some more screen grabs as the water continues to heat. It would be particularly useful to see what the heat pump c...
I think that is a very good idea. Point out gently that doing these tasks will make life easier for everyone/what if the heat pump does destroy itself...
@burtis - another, more worrying point occurred to me. I think at some point you may have said you asked your installers not to add antifreeze, becaus...
That's interesting. I don't think I've ever seen a flow rate that low. My problem is the flow rate tends to be fixed at around 1.4m^3/h, and that cons...
It has been said that Latin is the last refuge of the linguistic scoundrel, but putting that aside, how about a recaleferator? If they got away with g...
