I've got a question regarding water pressure before i fit a new combi boiler. I'm hoping you can help.
I'm looking to fit a boiler on the first floor of my house (outside the bathroom), with the flue vented through the roof. This, for me, is the best position in the house.
The problem that i have got is that the water pressure upstairs halves when the kitchen tap is turned on. The main stoptap is next to the kitchen sink.
I measured the water pressure and got the following readings:
Only kitchen sink tap on: 11-12ltr flow rate/ just over 2 bar.
Only upstairs bathroom on: 10ltr flow rate/ just under 2 bar.
With the kitchen sink tap on full:
Upstairs bathroom drops to 4ltr/ 1 bar.
Would i be able to fit a combi boiler or am i better opting for a system boiler and tank?
Your help would be much appreciated.
