Hi,
I am in the situation where the water pressure at the outside stopcock is 4 Bar with a 30 LPM flow rate. However inside the house I do get 4 bar pressure but through timing how long it takes to fill up a 10 litre bucket I only get 8.2 LMP downstairs and 6.6 upstairs (not sure if this is a very accurate way of ding this). On top of this I have an old boiler that in the first quarter cost me £160 in gas bills on top of the £49 I am paying a month. Also the boiler I currently have heats water in a tank (i.e. its not instant water when I pull on the hot tap), and the new boiler is a gas combi (i.e. no need to use the immersion tank any more). The plumber who has sourced the boiler has told me that the minimum flow rate has to more than 11 LPM.
So my question is can I use a single impeller pump to increase the flow rate of the cold feed into the new boiler? My reason for asking is because I am aware I have a 15mm supply from the outside stopcock and I am looking at extending the house so I will replace the pipe when I come to do the extension but that will be in a few years. So is this an acceptable short term solution?
Thank You,
Nathan
