Hi,
Any help, advice or personal experience appreciated.
We are supplied by a lead pipe but on a shared supply. I am about house 4 out of a run of 6 or 7. When tested by Affinity Water no other houses seemed to be drawing water. If you were to run a hose and another house draws water the pressure drops to almost a trickle then builds up again.
Affinity Water Test.
Pressure at Outside tap = 2bar
Flow at outside tap = 13 litres per min
Flow at kitchen tap = 11 litres per min
Current water system consists of a cold water tank in loft and copper hot water cylinder in 1st floor bathroom. Cold water tank feeds bath,toilet,sink. All cold water downstairs that’s toilet,hand basin, garden tap and kitchen sink are fed by mains water. All hot is fed from hot water cylinder.
Heating.
There are 7 radiators fed from a separate radiator cold feed tank in loft. The pump is in the airing cupboard connected to cylinder and water system using a three port motorised valve. The boiler is a 29 year old Bali Solo power flue and the overheat cuts out when it wants. It has always been temperamental like this but has got worse.There is a gate vale on some 15mm pipe work between the flow and return to provide bypass.
Bathroom.
The bath has a set of mixer taps with shower hose and head. As explained before this is fed from copper cylinder for hot and cold water tank in loft. The pressure was appalling so I fitted a Stuart hot and cold shower pump under bath and this gives a lovely shower. One you have showered it seems to take a fair while for the cold and hot cylinder to complete re filling.
We don’t mind if we replace bath for large shower cubical and have to reconfigure bathroom we just want to achieve a nice pressure that provides a reasonable shower that does not result in pressure reduction or temperature difference when other houses draw water. (Also not keen on electric power shower fed by mains as we have also experienced flow drops when other taps turned on)
I have been looking at replacing the boiler and am now confused which would be the best option.
During my re search I have contacted water board for new water main out of the question at £5000.
Looked at mains pressure accumulator tanks that fit in kitchen cupboard. With additional ones able to be fitted in bathroom or loft. But would this supply enough flow for shower?
Pressurised hot water tanks but looked quite large.
Can anyone suggest a solution that will guarantee consistent water pressure and offer the best boiler choice along with a reasonable shower pressure.
I do not want to be in a situation where I go for a combi boiler which provides poor water pressure performance and then be bolting in additional things to try and resolve. Would like to make the right choice from the beginning especially as most of the pipes are under the kitchen floor so means removing some of the units. This will need to be done anyway as I also believe the gas to new boilers now needs to be 22mm which stops under the kitchen floor where it T’s off to the cooker and boiler in 15mm runs.
Obviously budget is important so not interested in mega expensive shower solutions that take your skin off and don’t want to spend 1hour in shower wit hot water but one that provides a reasonable normal performance with good pressure.
Appreciate any advice and possible solutions.
Many Thanks

- Combi boiler advantage no cold, hot water or heating tanks.( possible poor pressure and believe you can’t use pump on shower.
- Replace with similar boiler and keep existing setup however water pressure in bathroom fed by cold tank is still not the best hence the pump under bath.
