Hi been in my house for a year but do not have any hot water just tepid.In the last week had a problem with a couple of radiators that were cold took some advice by turning off the good radiators and just leaving the cold radiators on which seemed to clear it but now have no hot water.
Can it be an airlock as water runs fine just cold?
The boiler in the kitchen looks fine the pilot light is alight.
Any advice would be great to sort the problem
