Ravenheat DHW probs

[Vinno]

I have a Ravenheat CSi 85T and the CH works fine. DHW heats up gets hot and then boiler cuts out and then restarts - heats up, gets hot, cuts out etc

Have replaced the DHW thermistor but no success. Anybody any idea what next?

Many thanks.

Sounds like your plate heat exchanger could be the culprit

Nope Ravenheat=B+Q B+Q=some DIY knowitall Numpty Nuts = Hard working RGI going short= affects us all

balls to him

The clue is in the name of the web site

As long as he ain't messing with the gas then its fine with me.

Your in a bad mood tonight CM..Tough day at the coal face

Plate heat exchanger blocked???

 

[werewolf]

c/h sensor faulty.It acts as overheat as well.Could also be partially blocked venturi or faulty aps.Is heating going up ch pipes when on dhw.If so new diverter.Ravenheat cheap crap in my opinion.What i would class as a throw away boiler.
remember if you break the case seals you are responsible for checking for spillage and the flue efficasy afterwards.If you don`t know what you are doing phone local RGI.

The obvious cause is a blocked plate HE.

The "one post" DIYer has not apparently bothered to check that. Its usually because they dont understand how they get blocked so easily when the system is not cleaned.

So if Vinny is still there the first part to check with that symptom is the plate HE.

Normally I would be inclined to agree but this is a Ravenheat. The first rule of Ravenheats is to renew, test or otherwise eliminate the CH thermistor.

Perhaps its the reactor core that faulty? You nasty boys!

flux capacitor on that model

was the flux capacitor fixed as standard on this one, I am sure its probably the coal chute thats become uncalibrated, which in turn has misaligned the giggly pin which has throw out the timing of the selubricator

very comman fault
