Halstead Ace DHW heat exchanger needs cleaning Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

[MattHarding]

I have deduced through working through the forums that I need to clean the DHW Heat Exchanger in my Halstead Ace Boiler.

The hot water comes on, then after 30 seconds / 1 minute it goes cold, then after a while will go hot again, before going cold.

Can anybody suggest how to go about cleaning the DHW heat exchanger?

Thanks in advance
