Tado vrs ASHP

Hi @PastGasman and welcome to the forum.

@PastGasman

Dread subject: Volumiser/Buffer. I appreciate that most readers will be anti-buffer. I’m convinced too. The problem is that most installers are pro buffer. Now, given that our circulating volume will change as TRVs open and close, is that somehow an argument in favour of a buffer (rather than a volumiser)?

This may just confuse you further but have a look at Just a thought on bigger buffer tanks (including the links referenced from it).

Simplest: has anyone experience of the Panasonic M series? (Rather strange: its data suggests it pumps out the same heat regardless of conditions- for eg, whether its 7 or -7c, 12kW comes out, either at 55 or 35- can that be true?)

I suspect that this is not unusual. The table Samsung publishes for my 8kW HTQ series ASHP shows that energy output is 8kW (or more) over a wide range of ambient temps and LWTs, and the only area where I’d get <8kW is at very cold ambient conditions (below -20degC). What does change significantly is the energy input to the compressor, hence the variety of CoP values.
