Thank you for your replies. Yes Iv watched a lot of the videos , including the one for separate timer on hot water , should it not heat , this is set as advised 3pm and 3am. But I can check that . On the water law I set for 3011 and for Scotland , I can’t remember the secondary figure for that.
the hot water is suppose to be as I see it on a high of 48 deg., but never reaches that , so I set it for 50 deg.It doesn’t reach that . It barely reaches 42/43 and was the same before I raised the bar , so to speak. Before water is taken , bath wise in the evening , and the circulating temp is sitting at 52.5 the other night, this three hours after any hot water use, the water was still only 42deg. I’m wandering if it’s scavenging the hot water.
A separate Danfoss thermostat which is moved about controls the heating. It’s set at 20 c just now , generally it’s not too bad but sometimes it has I have to waken up the heat pump by increasing the setting and dropping again. The pump doesn’t respond well to .5 , so by the time you realise there is a lot of making up.
Presently, I pay 390 a month at 19p/kw, but was higher until I put in underfloor insulation. Not good.
The probe sits about a foot above the immersion.
