Hi Matt
Thanks for all the advice. I've installed the isolation valves and perfect pump valves and replaced the faulty 3-way valve - all seem fine. Filled up the system and fired up the boiler. Have not yet fed in inhibitor as only just done the job and wanted to check everything ok. Bled all...
Hi Matt
Many thanks for the advice - really helpful. Yes, heating and hot water controlled as you say. No disrespect taken at all - I feel pretty confident that I can drain down and change the three-way mixing valve (this is controlled by an automix controller) and cutting in the isolation...

Forgot to say, the pipework is all 28mm and copper. Changes to plastic running to house from just after the pump on C and from the T at D. There is a drain valve/tap on the pipework at the bottom of the thermal store.
Cheers

Hi Matt
Thanks for the reply. I'm not at the house at the moment but from memory the boiler is a Kunzel PL25, the store is also made by Kunzel and is 500L. Heating in the house is just by radiators. Not at house as I said so can't give piccies at the moment, but which bits in particular?
Cheers

Hi
Looking for a bit of help/confirmation of my thinking (as a novice). I've got a wood pellet boiler and thermal store in the garage, that feeds the central heating and hot water. Hot water storage tank and header tank in loft. A three-way mixing valve needs to be replaced so I need to drain...
Hello all
Managed to roughly map what is going on - hope it makes sense. Have not managed to map whole system, just the boiler and thermal store. These then link to system in loft (header tank, hot water storage tank). Could not see any isolation valves other than those on either side of the...
I think the pump is fine (it's just some crud stuck to the front). So, no other way than to drain everything down? Assume that means thermal store, radiators and water to the hot water tank?
Hi All
My first post here but I'm looking for a bit of advice (I am a willing novice). I've a wood-pellet boiler and thermal store in the garage. It provides hot water through the radiators in the house and feeds the hot water tank in the loft, where the header tank is. There are no other heat...
