Still NO Hot Water to Rads...
Any ideas would be appreciated...Thanx
Domestic hot Water Fine..
But CH fires up Hits 80C in 5 secs & trips out until temp drops to min 30C & then fires up again(3 mins later approx) then hits 80C in 5 secs...trips.... & repeats this cycle???
Ch heating thermistor mate, its a £3 part which you can change yourself and if (when) it works insist that your divertor is changed back and do not pay for a bad repair job.
How easy is it to fit this "Thermistor" ??? & where is it located on boiler.
Many Thanx
It a little plug with a wire to it on the flow, its dry (no drain down needed) and will come out with a 13mm spanner
