Can any one help
The hot walter runs hot then cold about 30 seconds
I have replaced thermistors
overhauled the diverter valve
replace over heat stat
checked gas perishers
Cleaned out secondary heat exchanger
represhrised expansion tank
The water preshure is high
checked the fan
checked the pump
The only way to keep it running hot is to restrick the flow so it is very slow
could this be the heat exchanger , but i did clean it with caustic soda but did not get much out .
is there any thing else to clean it with
I have checked other threads but can not work this out
wolud be grate if some one can help
