Hi all
Please help me. I have a glow.worm combi 30ci boiler. The water doesn't get very hot ...only warm. Not very good for bathing a baby. Any advice to what to check?

run the tap slower... it may just be you have very cold incoming mains water. if this fails then 'get someone in'
again all combination boilers have a set temperatur rise that is related to the temperature of the cold mains and the flow rate. check that the hot water stat is turned up for winter. if the boiler cycles on and off with the hot tap running then could be the heat exchangers suffering from scale.
