Ravenheat condensing boilder not keeping rads hot


Postby msc1306 » Fri Mar 14, 2008 10:19 am

:( Please help - my ravenheat boiler comes on fine but after all rads reaching required temp the boiler keeps coming on/off every minute or so, thus, not giving the water in the system enough time to keep the temperature in the rads. The hot water also doesn't stay hot. Any ideas.

msc,

Could be lots of things!

lets start with: -

Does the boiler rapid cycle occur in response to rapid switching of room themostat?
(faulty stat or positioned in wrong location)

Any air or sludge in system?
(vent air. drain/flush/refill).

Try to establish if pump is circulating the heated water away quickly enough.
(if adjustable, increase pump).

System balanced including bypass?

(balance system)

Lets see how you get on with these first!!!
