@jamespa not found the hysteresis to be a problem yet. The house warms up a lot in the sunshine so it’s only back to our desired temperature by later ...
Ours is 1000 starts in 3200 hours running time over 6months. So twice the rate of James, but again nothing I will worry over. Nice discussion from M...
@jamespa use expanded mode! It’s ideal for that, and I’ve just moved back to it.
@gary thanks for that link. A very useful analysis and I’m pleased to read the author’s view corresponds to my quick glance on it being some batches. ...

Nice data set Gary. Tesla clearly had a quality issue with the PW in 2019-20, in that many are showing much reduced capacity even with few cycles. We...
Our Vaillant at present (outside temp 18C and the heat pump is off since internal temperature is above the set point) has a target temperature for wat...
they do allow a volumiser to be used, so the obvious question is could a 4 port buffer be configured as a volumiser and stay in warranty?
@pooneil Hi and welcome. I have to say you are thinking like a gas boiler and heat pumps don’t work well being treated that way. It’s best that you ...
Our solar hot water is now 2C above the set temperature the pump got it to at 1pm. Thats the upside. But solar PV, nominal 6kW was generating 5.6 at n...
Great progress so far, keep going you’ll get there! Your Welsh cottage part will have a very long thermal time constant, as you probably already reali...
Mixer showers need virtually identical hot and cold pressures (or at least our new one did) or you need a high flow to mix properly. Our mains varies ...
