Hello All,
Please can anyone offer some advice re the above? I have an older combi W/Bosch 28cdi which is fine if we use the shower either very early in the morning or later in the evening when the water flow/pressure is O.K. If we use it in 'normal' hours (6.30-9.30am) we get fluctuating water temperatures and god forbid anyone uses any other tap or toilet in the house.
We've had the boiler serviced and had various parts replaced (heat exchangers etc) and a decent thermostatic mixer shower is fitted. Hot water to the taps is fine for a combi. I know combi's suffer if pressure/flow rates are poor so I want to try and improve the water supply before either getting a newer high flow rate combi or getting an unvented cylinder setup. We only have one shower (because of the problems above) but I would like a second shower in the downstairs bathroom that we could use at the same time as the upstairs shower, eventually.
I've read through lots of threads advising on how to improve flow rates and pressure, I've got about 2 bar static pressure and about 15l flow rate at the very best. At worst I'm looking at about 1.1 bar pressure and about 12 lpm flow rate (pretty much the top limit of the combi boiler anyway). I'm not sure how to work out the dynamic flow but I'm assuming it's bad?
I've got a 15mm incoming copper water main in the kitchen of a mid 50's built bungalow, 2 bathrooms and 5 adults. The question is will a new mains pipe guarantee improved flow rate or pressure or should I get an accumulator or even a pumped accumulator?
Many thanks for any input.
