Does The Heat Exchanger Get Serviced During A Routine Boiler Service?

I had a service on the boiler about three months ago and had to call them back as the water was not running hot on my combi boiler. The fault was rectified by cleaning the internals of the heat exchanger with acid. Would this be done during a service as I am now being expected to pay over 60 pounds for this. Any help would be appreciated

Its just bad luck i’m afraid,whoever is doing the repairs for you is not trying to rip you off as they could have charged a lot lot more.

No it is not part of a normal service, in fact many companies only do an annual inspection (look at it), and don’t clean the outside of the heatex, you are very lucky with £60, most would have flushed the complete system at between £250 and British gas at £180 per radiator plus vat.

Acid flushing of a heat exchanger is not part of a service. £60 for an acid flush is cheap, no gas jobs are cheap. Average boiler service costs £75.

I don’t think this would be included.
The heat exchanger is where all the deposits form if you have hard water, as it is exactly the same fur that’s in your kettle.
Because the channels of the exchanger are narrow, it makes a big difference.
Designed to fail = more money to them.

It is not part of the service and are prone to blockage.
My service engineer volunteered to remove it at each service and wash through under the tap. That would keep most of the blockages at bay. If you have it done at service you are not paying for call out and as it is not a difficult job, need not cost much extra.
Ask the engineer to fit a Boiler Buddy. They cost about £80 and fit in the supply pipe. They magnetically attract the iron particles from the rads and you can see if they need cleaning. At which point you isolate at each end, remove, wash out and put back.

Would have thought this was one of the important checks to be carried out on a routine service, make a complaint to them

i think £ 60 is cheap but that is not normally done as part of a service, i would have thought a good engineer would have replaced the diaghram first, or checked flow switch , there are a few variables here age of boiler etc . as a point of note i will repair boilers if worthy but i do give my customers the choice to replace the boiler of it is more beneficial the reasons for this approach is because EG: say the boiler needs parts and labour which could be £300-00 and it only replaces one or two parts and solves problem in the short term, it may be a model prone to breakdowns due to age / usage etc. then for i will say a few quid more have a new condensing boiler economical , guaranteed and customer are left happy . or do you keep wasting money on repairs.
