Hi All,
more by way of a query really, we had an Iboost (immersion heater proportional controller for diverting excess solar power) installed when our panels were put in last october and the thermostat recently failed on the immersion heater - in such as way as the Iboost keeps providing power to the immersion until the secondary safety cutout trips. THis happened initially on the one sunny day in january and i reset the thermal cutout, to see if it was a one off, and the next sunny day it tripped again (so i have left it off for now until the thermostat can be replaced by a competent person.)
It is a new house and so still under warranty and talking to the guy that came to look he said that the only other person on the estate that had a failed thermostat also had a immersion diverter. and that as we had modified the system it wouldn't be covered by the warranty. Not that concerned about the warranty aspect, but was wondering if anyone had any thoughts on whether the iboost and similar proportional controllers do lead to failure of the thermostats. or is it simply that the thermostats are simply prone to failure.
The system is a pressurised hot water system - heated by gas condenser boiler normally, so i figured that the only people likely to use the immersion would be people with this type of proportional controller as gas is inherently cheaper. so could either be unreliable thermostats and most aren't being used or something about the proportional controller is leading to early failure. I have read a few forums where people say they have had to have the thermostat replaced but only one or two.
The immersion and iboost are off at present i figured that was the safest until i can get someone to change the thermostat.
while everything was operational it appeared to work well so i am hoping i have just been unlucky and i might get more than 4 months out of the next thermostat.
Any thoughts welcome
