We need an urgent advice, we have a gravity water system and we are in a middle of loft conversion. We are adding an en-suit in loft and prefer to have a good water pressure there.
What we want, is to either be able to run multiple showers at once, or if one person is having a shower, other people can run taps/use water within the home. But we are not sure if it is achievable due to limitations. At the moment we can only use the water for one thing in the home, which is making it very difficult on our growing family.
The water supply from the main is shared so there is no option to replace the water pipes. Here are the readings;
Static Flow: 16-18 l/m (using garden tap)
Dynamic Flow: 1 l/m
Static Pressure: 2 to 2.3 bar (using garden tap)
Dynamic Pressure: 1 bar (garden and toilet taps)
We had a discussion with different plumpers and they all had different opinions. Here are the options which we got from different plumpers for running multiple showers;
1- 35kw to 40kw combi boiler
2- 210L unvented cylinder with existing 18kw boiler
3- Unvented cylinder with DAB pump using existing boiler
4- Unvented cylinder with system boiler
5- Stick with the gravity system and include water pump ( hot water cylinder and pump will have to go in bedroom due to lack of space and we are worried about the pump noise). The water tank in loft will have separate mains and multple showers can be run at the same time.
We would really appreacite if someone can give us a professional advise here as we don't want to spend money on a system which is not going to work at the end.
