Hoping the ST hive-mind can help me with this one!
We have moved into a house with a combi fitted, first time I've had one.
I'm a bit disappointed with the performance of it, tbh. CH is ok, but DHW seems lacking.
I've went round all the hot-water taps in the place and they all seem to be the same- I get an output of about 5.5 litres of hot water per minute. Bath fills, but takes a while.
I'm going to call in a professional soon, but a friend noticed something he thought odd- the boiler is on the 1st floor, and seems to fill from a cold-water tank in the attic. The tank is definitely filling up, and has fresh cold water in it.
Is this unusual?
