flow rate

I have a Samsung Gen6 8KW air source heat pump. It works very well, but I noticed that my flow rate is between 28 and 31 l/m and I wonder if this is too high? The circulating pump is a Grundfos UPS2 (8m head I think) on setting 3 which I understand is suitable for larger heat pumps than mine. Is...

Hi, I currently have a combi boiler which drops flow rate when a second tap is turned on. I'm also looking to add a second shower. The flow rate i have is 12 ltr per min and i cannot install a blue pipe because a i have a shared mains with the neighbour. I have a couple questions: If i place...

Hi my really old large house used to be a real mess in terms of several old heating systems that were cobbled together and extensions to it. Not to mentions redundant pipework from Back boilers and a Rayburn/Aga style device in the kitchen. Now - I have the original gravity fed Potterton...

The rising main in my downstairs bathroom looks like galvanised steel- 27mm by my measurements, which eventually joins to 15mm copper in the kitchen. I'm looking to tee off somewhere to feed an unvented cylinder, so need the best flow rate possible. My question is, would the flow rate be better...

Hi All Please can any one assist with an issue with a Mira Sport Airboost 9KW electric shower that’s been newly installed however the flow seems much poorer than the old Gainsborough E 8.5kw electric shower it’s replaced. The power supply wiring has been upgraded to 10mm as part of the...

Hi I have pressure of 1.5bar about 14L/min flow rate with 2 thermostatic showers and so was thinking Ill get a a combi that heats about 14L/min. Worst case is Ill get 2 showers 7L/min which is okayish. However someone suggested unvented cylinder if 2 showers but how will this give me more L/min...

We've just installed a new Mira Coda Pro ERD shower as part of our bathroom re-fit. Our oil fed boiler is a Worcester Greenstar. I was worried that the flow rate wouldn't be that good, but it's the opposite. The shower waste is just about coping with the amount of water and I think I need to...

Bit of a long saga*, but today the water company came out and fitted a new stopcock at the roadside, because they said the old one might be leaking. The chap said it would be much better to have a new stopcock anyway because the new kind are much easier to turn on/off than the old ones. Anyway...

Hi all. OK, I know you get this a lot and I apologise. I've read a lot of posts regarding the 'best' boiler and I'm not asking for that, only some advice on who to believe and your own boiler preference. The situation: A three storey town house. Gas enters at ground floor front door, rises to...

Hi all, we have just bought a new place and the water pressure/flow rate out the hot taps is very low. There is a Condensing Combi boiler, Worcester Greenstar 28i Junior that is in the loft. So there is a ground floor and a first floor in the house and then above that is the loft. I have had...

Hi, We have recently had our kitchen taps replaced as part of a refurb. The work was done while we were away and the plumber replaced my existing tap tails (which had integral stop valves) with separate stop valves and new tap tails. Therefore the stopcock was turned off :-) On our return, the...

Hi, I am new to the forum, I have a query about the megaflo eco plus unvented indirect cylinder, if anyone could advise me. My mains is 32mm and I think I have a flow rate of around 30l/min (whilst my mains are 32mm, all my house pipes are 15mm which will be replaced when the system is...

So I replaced my bathroom sink tap a couple of weeks ago due to my old one breaking. (The plastic square protruding part of the mixer cartridge on the old tap snapped, could not source a suitable replacement.) Got my new mono mixer tap from ScrewFix and since fitting it, I have noticed an odd...

I have the above boiler and am getting a flow rate (measured from 2 different taps) of just over 7 litres / minute. The quoted flow rate (with a 35 degree rise) is 14.6 litres / minute. I realise with outside temperatures (and therefore water input temp) low that I wont get 14.6 l/m but should...
