So, before I throw money away on a new boiler that will put a dent in my finances, better ask here and then look for a boiler engineer willing to repair rather than replace.
Worcester Bosch Greenstar 28i junior, 17 years old.
Central heating works perfectly, all 10 radiators get very hot very quickly and boiler doesn't make any weird noise (in fact, hardly any noise) when running central heating.
However, turn hot water on and I get hot water for about a minute, then hot and cold rapidly, 10 seconds intervals.
Boiler makes a ticking noise when doing this.
This happens with every tap in the house.
7 out of 10 radiators are new, installed in March, flushed before installation and always worked perfectly.
When system was drained, there were no debris, water was clean and of a very pale yellowish colour (inhibitor?).
2 plumbers looked at it and suggested a new boiler due to age (they don't know each other), but as said, I would prefer to repair if possible.
What could it be?
The 2 plumbers wouldn't say.
Thanks
