My apologies. R32 is not the combustible refrigerant so the isolator is ok under the unit. I also relised the antifreeze valves are upside down so going back to change that.

Dread to think the cost of all that lot even before you arrived ! Think i would go down the electric boiler route when the time comes.

If the heat pump was sized correctly the buffer would not be required. Could have been a lot cheaper

Hi AM, what a bodge job that was. Did the client call you in or the original contractor and was there any obligation by them to make good?

The client called me but the instalation company agreed to pay.

Man,they look like an absolute nightmare to work on.Thats a joke having products of that size in those locations.

The antifreeze valves are upside down?

Yes i noticed that tonight. Going back on thursday. Dont tell any one its our secret

Andrew, you fitted the AFV valves the wrong way around - they are upside down! Also, no need for that PRV, there is one inside the unit.

Ive already corrected the freeze valves. On the schematic i could not tell if a prv was inside. The schematic seemed to suggest external. As the original instaler fitted one outside og the pump.i played it safe. Not my chosen position either i just couldnt fond space inside. Do you absolutely know ome is inside?

Hello, I have a question that is not related to this clip. If you can tell me what to choose between Wiessmann Vitodens 100-W BIKF 25KW Combi and VAILLANT ecoTEC plus VUW 26CS/1-5, 21 kW, for a 4-room apartment. I am not interested in the price difference, but in performance, quietness and durability. I'm not from UK, I'm from Romania.
