Hi I have a Greenstar heatslave 25/32 external boiler. For quite a while now the hot water has been losing temp after less than 5 minutes. The water drops right down to not even lukewarm. However if the heating is on, the water temp is better but still not as hot as it used to be. The CH works fine, I have had the sae firm that service the unit out to look at it but they have so far replaced the PCB and the DHW stat and neither have Mae a difference.
Wondered if there is a problem with the secondary heat exchanger? I also wondered about the diverter valve but I thought that would stop us even getting as much hot water as we get.
We had a leak on the main water line going to the boiler underground requiring putting in a new pipe to the boiler, could this have caused an issue with debris having got into the system.
Any help much appreciated.
