In DHW 'summer mode' we've set it to heat the top of the TS to 65 iirc so the boiler ( which is now a dumb box on the wall set to do as its told and nothing more ( practice differs slightly from the theory as its logic tells it to modulate as it hits the drop off point )) and therefore should just go at full wallop until that stat clicks to satisfied, where it should go into overrun and then standby. Yep, that's what I've observed. Firing on 24kw then straight back to standby. 27 minutes ago, Nickfromwales said: Without picking this apart for its failings, it works, so a result afaic. But its still in the back of my head that we walked away without hitting 100% ( instead we left more than reasonably happy that we did what we could with what was there ). In a PM I called it "polishing a turd", guess ill never make it to the parish council "More tea, Vicar?" I am more than happy with what you achieved here. And the turd is looking pretty shiny from where I'm sitting. I've called it much worse in the past, and who wants to be on the parish council anyway .... 2 Link to comment Share on other sites More sharing options...
SteamyTea Posted April 15, 2018 Share Posted April 15, 2018 Most of Cornwall is a polished turd, why the outer edge looks so good in postcards. Old mate of mine is on the local parish council. He is from 'Up North' somewhere, and I don't mean North Country (look it up on a map). 1 Link to comment Share on other sites More sharing options...

And what does the heat differential need to be between TS temp and the collectcr for the ST to actually heat the TS? I'm afraid it's like how long is a piece of string! Direction of solar panels, type of panel, and angle of mounting, etc. We have a large flat panel, facing SSE, at about 45 degrees. On a full sunny day in summer, it can get our 300 litre tank up to around 60 degrees, but usually it heats up the bottom third by about 25 degrees. That's in Perthshire, so I'm sure others further south will do better. The system is set up so that the solar panel has to be more than 7 degrees hotter than the bottom part of the thermal store before pumping begins. 1 Link to comment Share on other sites More sharing options...

I don’t have much info on that score other than the receipt for the purchase and a photo of them on the roof. They are pretty much south facing I believe (well I am on the coast and they point in the direction of England anyway!). The TS is 475l.

No dopy, its so you can isolate the aav and remove it without draining the antifreeze out. 1 Link to comment Share on other sites More sharing options...
