Nice and quiet heat pump. Going through planning was a bit frustrating

Here goes.  I will do what I can!

@squarepeg77

Welcome to the forum.

The value given for 'Total Output of Heat Emitters: 7.4kW' seems rather low. Is this at the standard 50C Delta T?

@derek-m 7.4kW is the sum of the “output at design temperature” figure from my radiator schedule.

@derek-m 7.4kW is the sum of the “output at design temperature” figure from my radiator schedule.

The standard way of denoting the thermal energy output capacity of radiators is at a Delta T of 50C.

Ah, sorry. I don't have that figure to hand.

Although from memory I think the output at Delta T of 50C is a bit less than 2x at our design temp of 50C max flow.

An update on my system:

Im in the process of updating the heat pump roll call. Can you please visit the first post of this topic and see if you and your heat are on it. If not, please simply leave a reply with your heat pump size, model and brand. You don’t have to the extensive detail if you don’t want to.
