Hi all just after a little bit of advice.

just had a worcester bosch greenstar 15ri installed but since its been fitted the only way to turn the heating off is to turn the temp right down on the thermostat.
even when the programme controller is off it will still fire up.
Do you think the boiler as been wired up incorrectly or is it just a coincidences that it as developed fault straight away?
the old boiler was a potterton envoy 40g, programme controller is potterton ep2002 and the thermostat a prt100.
thanks in advance.
 
Do you trust your installer?

Hi, I have a Vailant EcoTec Boiler with a Megaflo. These are controlled by a Honeywell controller. I have one 3 port diverter, where one of the outputs goes to a 2 port diverter prior to the Megaflo (I believe this is some safety feature). I have run into an intermittent problem where some...
