How can i fix my Revenheat boiler hot water problem ?

my ravenheat boiler. It heated the radiators fine, but not the water - unless the radiators were already on.

There is a water stat in the pipe to the left of the heat exchanger which senses the temp of the incoming water. Easy to replace - pay about £20 for it. Beware, it is MAINS water so turn the supply off before you remove stat
