Hi Guy's, I am moving into a property that currently has storage heating and no gas supply. The hot water system is a vented set up with tank in the loft and cylinder in a cupboard under the stairs. I have arranged for a gas connection to the house but am left wondering what to do for the best for a new water/heating set up? the house is a standard size 3 bedroom semi with one bathroom/toilet. Would a combi suffice and provide ok water pressure to an upstairs shower? as I have read a shower pump cannot be installed with a combi. If a combi is installed would the cylinder come out or stay as a hot water back up? Or would a system boiler with the cylinder be a good option? Sorry for all the questions!!!
