Hi,
We have poor mains pressure (2.5bar and 10l/min at the best). We currently have a Baxi combi boiler which, while fine for central heating, suffers from poor pressure when creating hot water. It will merrily produce hot water from one tap, but if a cold tap is turned on at the same time, the hot water flow stops to a trickle. Now, we are planning on having a new bathroom installed and hope to have a good, powerful shower. To this end we talked to a friendly plumber and he suggested the following:
1) Install a copper hot water cyclinder
2) Install a cold water header tank
(we have room in the loft for both the cold and hot water tanks but he suggested putting the hot water tank either in the bathroom or a bedroom and the cold one in the loft)
3) Install an Aqualiser Quartz Digital concealed with 105mm Harmony head - Gravity Pumped shower which has a built in pump (1.5 bar)
4) Install an imersion heater into the hot water tank
5) Feed the heating pipe from the combi boiler into the indirect inlet of the hot water tank, thereby heating the water in the tank whenever the central heating is turned on and using the immersion heater when we need a top up or the heating is turned off
My questions are really about the planning of this setup; is it reasonable, sensible and logical ? Will the combi really heat the water, and will we get a good shower ?
Many thanks
Andrew
