hi folks,
info 1st: old house, mains fed everything, combi (bungalow , upstairs converted, no room for tanks up there even if u wanted them) and known low water pressure in the area (also made worse by a mains lead pipe from pavement to house, yes I'll replace when I get round to digging a very long trench in very steep garden...! But won't solve low pressure completely..just flow rate a bit maybe..)
So... I plan to install an upstairs en suite soon and know the additional height won't make for good pressure (probably?) and would like to improve things so a tap can be turned on in the kitchen for example without the electric shower in (existing) bathroom cutting out due to low pressure and make use of the combi to power a shower in the new ensuite upstairs which would only be possible with better mains pressure. (no plumbing upstairs just now easily added though..)
Plan so far:
Install cold tank in cellar with fast fill type valve from mains and feed entire house (cold and feed to combi for hot) from a single pump out from the tank. (At present the mains in just splits off to feed all cold taps etc and boiler in for HW near cellar anyway. Plenty space, easy fit..)
Questions
1. Does this sound an ok set up? Any better suggestions? eg: more than one pipe out of tank hot & cold twin pump instead etc??
2. What size tank? (i should measure mains flow rate right? i will when my dishwasher turns off later!! to work out how fast my tank would fill?)
3. What pressure of pump? Does a 1.5bar pump keep 1.5bar no matter what is turned on, or does it drop when a shower is used and a toilet is also flushed? so therefore you really need 2 or 3 bar etc...?)
4. Make of pump? (noise not an issue in cellar, reliability & up to the job does..) I'm pretty good with plumbing etc but no experience of choosing pumps...
5. Am I right that my combi (an ideal mini 24kw flow rate 10l/m 35C rise) will power a shower ok if I increase the mains pressure fed into it doing the above?
EDIT-- forgot to say yes i know already to have kitchen cold tap mains fed not from tank and perhaps the loo too just to decrease pump going to when not needed.... --
Any input on all or bits of above appreciated!!!
thanks folks..
