Moving into a new house in a couple of days and trying to figure out the layout and plan the resulting chaos.
On one wall is a boiler with a cold water feed, is it possible to insert a t piece and take water from the feed pipe to route to washing machine etc.
Current layout of kitchen means this is, in theory, a more sensible approach than taking water from sink area.
I'd take it from the sink, unless its a refil pipe for a combi system
basic layout, sink on right wall, boiler on left wall, no space currently on right wall for dishwasher and washing machine, lots of space on left wall.
Yes i know i also have to think about the drain as well, just trying to get my head round options.
I can't see a problem with that, even if not a combi. It's all cold water coming directly from the mains. IANAP.
Not an expert at all but the boiler will probably require a minimum flow rate/pressure to allow it to run.
I expect you will be able to find the specification for the size of pipe relative to the length for the boiler online or in its manual.
Potentially your boiler may cut out when your washing machine is filling with water. A bodgy option might be to have a pressure reducing valve by the washing machine and dishwasher as it really doesn't matter if it takes a few minutes longer to fill the post ride washing load if it stops your shower going cold everything the machine tops up the water level!
If I recall there has to be 1m copper pipe and fittings connected to the boiler, so if you are using plastic fittings consider that.
Ianap but
If you utilise the cold mains feed to the boiler for the washing machine you will not be able to shower when a wash is on.
The way a wm valve pops open and fills is quite sudden and will rob your dhw ( the hot side) of flow and pressure.
Enough to unbalance a thermostatic mixer.
Plus probably enough drop to actually switch off the combi, unless you hugely throttle back the wm inlet. Alot of combis use a hall effect semsor on a spinny wheel, when its spinning the combi knows there's dhw demand. No spinny, no hot water , angry wife, unhappy life.
thanks for the comments, I'll have to get a plumber in to discuss options at some point. If anyone can recommend any Gloucester way appreciated.
We did 25 years in our old house with what you describe - combi on wall with washing machine underneath - tee off cold feed approx 500mm before combi. Shower with thermostatic mixer in the room behind and never gave any problems (with both ancient and modern Worcester Bosch combis). Would occasionally be running washer and shower together e.g. just back from an MTB ride.
