hi thanks for that, should i bother getting trvs for the 1st and 2nd floors then or shall i just use normal lockshield valves and just trvs on the 3rd floor, another idea i had was to put full bore isolating valves on the flow and return on the 1st floor just before the manifold and leave...

hi all, i have a town house (3 storrey) just getting ready to install my new combi boiler (vaillant). Im running from the boiler in 22mm to a manifold and from the manifold in 15mm, this is on the 2nd and 3rd floors, But here is the question the ground floor, has 22mm to a manifold then...

gas 4 u, i have chased the gaspipe back to the meter and i feel, if i need to get someone to run another pipe in it shouldnt be too much of a problem, i know where im going to install it now, and i feel with all the help you have given me it has taken a large weight off my shoulders, thank...

gas4u, when you say doubtfull, do you mean the gaspipes need to be a larger size, or the boiler needs to be closer the meter

with calculating the elbows, the boiler will be about 9 meters away from the gas metre and all pipe is 3/4" and i intend on installing a 37kw boiler, am i fine

i have measured the flowrate now from the kitchen tap, and that delivers a good 21 litres per minute so a lot greater than the 14.5 letres per minute i get on the 3rd floor ive also checked my gas pipes and they are 3/4"

i have measured the pressure and flow, so here goes i have static pressure of 4 bar, and a flow rate of 14.5 litres per min open pipe on the 3rd floor coming from a 15mm pipe. i have looked at the vaillant ecotec plus 37kw combi boiler for this house, any ideas

hi i managed to get a pressure tester, but no flow cup, i do know where to get one from so will pick that up next week, i only just put the mains tester on the garden tap so far which is a very short tee off the kitchen tap and the reading is 4.5bar, which surprises me, if that is the case...

going to get both a flow cup and a pressure tester, what sort of result (min) do i need from both pressure and flow thanks

gas As im in a town house i have no loft so the f+e tank is in the top of my built in wardrobe on the 3rd floor, im going to do it today, but what is the best way to measure, so i go out and get a measure or is there a better or madebe easier way,

thanks gas 4you, but from what source is best, shall i get it from the mains to my f+e tank, or shall i run a hosepipe up the side of the house from the mains and measure that way, or any other ideas accepted

hi so after Tony's response, i suppose i do need to worry about the pressure/flow. If im going to measure this properly how do you suggest i do this, i want to measure the flow and pressure on top floor as well as ground, any ideas

so do you think i need to worry about the pressure or flow of the mains coming to the house, if i go for a 37 or 40kw boiler, and just keep the shower electric, also am i forgetting any other important stuff thanks

i want to spend about 1K on the boiler and im going to do all the pipework myself, we mainly have showers, so am i still looking at the 37 or 40kw boiler. also is it worth me measuring the pressure of mains on the 3rd floor, i was going to measure this out of the mains to the current f+e tank

no thats the only shower, and the only bathroom, and kitchen is on ground floor, nothing but 3 rads on 2nd floor

good point, i must add i have the bathroom on the top floor along with 3 rads on each floor. Also i currently have an electric shower plumbed in is it worth keeping that or plumbing that into the combi also

hi all, I've had enough of the indirect system i have with a very old Glow worm boiler, so moving into the 21st century i think its time for a combi as its only myself and my partner in the house. BUT before i start doing anything to drastic, is there anything i really need to do or look into...
