Does the SCOP figure on this site include DHW or is it just for space heating?

[MdeP (MichaeldeP)]

Good Afternoon.

I have had a 5 kW Vaillant Arotherm Plus heat pump installed since August 2021 and have achieved a SCOP of 3.5 in both heating seasons. But my PassivSystems monitoring doesn’t allow me to easily separate DHW use from space heating use. I have looked at the awesome SCOPs achieved on this site and I just wondered whether these figure of 4 and above included DHW, or were just for space heating only?

Does anybody know?

Thanks

Does anybody know?

The ones that have DHW do include that in the SCOP as the system cannot yet differentiate to record separately.
To me it seems that all systems have DHW apart from 4+1

If you open the systems and look at the graphs you will notice the DHW cycles

Welcome Michael!!

We have a Arotherm thread here.

Vaillant Arotherm Owners Thread

I thought it might be useful for the Vaillant Arotherm heatpump and its owners to have their own thread. So any questions, queries, things we’ve learnt and performance chatter can go in here. For starters, anyone looking for in depth performance information, this technical document from the Czech Vaillant site is gold. edit: I have uploaded the PDF rather relying on website links that sometimes change. For example, here are the COP and heat output charts for the 5kW model at various flow tem…

Thanks Mick: It’s a little overwhelming here: so many options. My intention is just to see what people are up to and try and learn how to operate teh heat pump better.

We’re just about to have our first cold night so it feels like were getting into ‘heat pump season’.

All the best
