Well found out why dhc was cycling Stupid me assumed that the microswitch on the diverter was working because I could hear it click We have hot water!!! Now to figure out the heating, pcb arrives tomorrow

Good call, ive got the schematic, and the pcb appears to be well labeled. So checking continuity of most sensor wires whilst fiddly shouldn't be too difficult. It would explain some of the random behaviour I'll report back

I can watch the pin from the diverter move out as a hot tap is turned on and operate the microswitch. The burnerscignite but go out after a 2 or 3 seconds cycling about every 10 to 15 seconds Im at work atm but I did put my hand into the flow of water from the hot tap, whilst it was not hot or...

I for my sins have a ravenheat csi 85 combi boiler and it has been a pig for years. Recently the pump has been making lots of noise and last week I woke up to a cold house, but the hot water worked. So a refurbished wilo pump was ordered and I replaced the old one (head unit replacement) the...

My skill is up to the job you describe (if not overkill for the situation) thinking about it logicaly I assume that the thermostat is powering a relay and that probably the contacts have stuck, I will hunt for that today. failing that i may aswell replace the fridge, they are very cheap. the...

I have a beko larder fridge and recently it has been way too cold so i replaced the thermostat, even on the warmest setting (1) it is -3.5 any other ideas?

when i bought the house i was told that it had run radiators in the past but had been disconnected when "modern" heating was installed and had been run for a few years without It is all cast iron, it is either water tight and preasure safe or not but as just a log burner it is rubbish, I am...

I have an old multifuel burner in my lounge, it is a coalbrookdale severn I believe it is 14.5 kw ! it has the ability to heat water but this is not being used so essentialy it is a metal box sat inside another metal box, not great for radiant heating. I have a couple of thoughts for the summer...

capacitor ordered if its still flaky ill look at going the whole hog and getting nest or hive !! I already have programable stats on the bedroom radiators (all houses should have them!)

yep it's a drayton wireless stat and if i short out the stat conections on the boiler it springs into life :) ill google and see if i can find the fix you are talking about thanks for your help

Its a wireless stat and the receiver has a led to show its receiving a signal to ignite, complete with an overide button. the led lights when the stat calls ill diss ravenheat to the grave!!!! one day when i have the money i will replace it, take the old boiler outside and make a youtube video...

My ever unreliable ravenheat combi is playing up again DHW is fine and hot, the preassure vessel has recharged great and water preassure is constant but the CH is unreliable at regular interval (at least every other day, if not every day) when the thermostat calls for heat the boiler sits and...

just so im prepared, should i need a new expansion vessel, ive been looking at the zilmet range. I believe this should be plumbed into the ch return to the boiler and they come pre charged. afaik the ravenheat csi85 has an 8 litre vessel, do you replace 8 with 8 or would going to 12 be of any...
