Hi
Just installed a thermostatic shower and noticed it runs hot for maybe 30 secs then goes cool for maybe 10 secs , then hot for 30 secs and continues on this cycle.
I hadn't noticed this before and thought the new shower was at fault but when running the kitchen hot tap the same cycle happens , boiler cuts out after 30 secs or so then re fires.
The boiler runs constantly when the heating fires in the morning but hot and cold water still occurs.
It's an Ariston Genus boiler about 12 years old.
Any ideas as to possible fault ?
Thanks.
