I have a Worcester Bosch 230 combi boiler which has just developed a problem heating tap water if the volume running is more than a trickle and even then its not what I would call HOT! The water to the rads seems fine as these get plenty hot enough. I just had a new kitchen fitted around the boiler which is around 7 years old new dishwasher plumbed in as part of the new kitchen. Any help would be much appreciated as I know nothing about these things.
Thanks,
