HEAT EXCHANGER??

[FINLM]

few months ago my water started running hot and cold then after a few weeks my heating shut off I called out a plumber and he replaced the heat exchange this worked for about a month now it has started again and then the heating went I was advised to click the overheat button underneath which I did and the heating came on but water still hot then cold and if run for too long i.e. A BATH the heating shuts down..The plumber I used gone into liquidation..Can you give me any ideas what may be wrong so I don't get taken for a fool again??

did you flush the system through before changing the HEX?

if not then its blocked again

sorry

I think the con man I used just changed it, never actually cleaned anything!

 

[corgiman]

well then

clean the system and replace the HEX

not cheap but worth it

Thank You, how much will it cost to have the system cleaned, roughly?? Us women tend to get ripped off.
