Also want to keep the heatpump volume low to reduce antifreeze required.



My understanding was that there was a min quantity of water required to prevent too much cycling. Perhaps you have taken accont of this.

 Very neat indeed George
        I give you 11 out of 10 for that. I had chaps shoot the face of the surrounding brickwork that took half a day to put right. You have the knack.👍

Looks like a cool project.

3kW output? How much did it cost and how much power does it consume? I couldnít find anything that small when I was building the garden office a few years back. Ended up with resistive heating will switch to storage heaters and a ToU tariff this year if I can. I even thought about butchering a heat-pump tumbledrier!

That heat exchanger looks pretty small, how much power can it dissipate with a 10 degree difference?

Not a lot more achieved - pipes into house installed.  More planned tomorrow but allotments call and  have to shear a few sheep am.........





When I installed my heatpump I knocked out a whole brick so,

a) It was actually easier than drill a large hole.
b) So I could cement in a couple of lengths of plastic pipe which would accommodate fully insulated pipes to reduce heat losses to the wall.

Now to the wiring ........ lets take the cover off .....


ok -mains is easy .
-sensors one labelled hot water tank and one labelled buffer tank ?  hmmmm
Trying to avoid a buffer tank and not heating dhw only radiators.....
Attach hot water tank sensor to heat pump output pipe and buffer tank sensor to heat pump return .
Struggling with manual and operation -manual doesn't seem to match my heat pump ? but have it running -quickly up to 47c with no load on heat exchanger .
