Hi My response 100 heat exchanger is leaking, losing pressure in the CH system, any idea how much and where's the best place to obtain a replacement heat exchanger or would I be better replacing the whole boiler? if replacing can anybody recommend a suitable boiler that can be fitted without modifying the existing pipework?
Regards.
Can anybody offer any help/ideas.
Are you sure it is the heat exchanger? If so a new boiler is the best way. Is it in a cupboard? Is there restriction around to put in a bigger cased model? What are you DHW needs? How old is the combi?
It looks like it is the heat exchanger leaking, I removed the burner and it was soaked in water!! It is in a cupboard but there is some space for a wider unit 580mm Normal DHW needs 2 bed semi with shower. the combi is just under 7 years old.
Thanks.
These boilers either last or fail early. Get a boiler like Worcester Bosch Greenstar or Glow Worm high flowrate models - 38-40kW. You will not be disappointed. Get the dimensions and make sure it can fit.
Thanks for that Doctor.
