Plumbing in washing machine

[i4got]

Anyone seen a setup like this before. Was expecting a hot and cold in feed.

What I seem to have is a black isolator tap and a cold feed only. Not sure why the cold feed seems to be tee’d off and not sure where the other side of the pipe st the floor goes.

Assume isolator is off as no water is flooding out.

Is it normal to have only a cold feed and are there washing machines that heat the water?

Yeah, they’re all cold fill now.

Is the pipe in the wall going to an outside tap?

[i4got]

Yes !! Thats it. Did not know they were cold fill only. Its years since i fitted one. Thank you.

Pretty sure that even when they had a hot feed they still heated the water

[Freakuk]

Yup, modern washing machines just have a cold feed.

I think… the pipe under the floor maybe the mains supply and the tee heads off to an outside tap perhaps?

The black isolator is on (open). The blue tap at the appliance connnector is off.

Ebac (UK made) do dual fill machines (scroll down the page a bit): https://ebac.com/washing-machines/range

Only if the hot water wasn't hot enough.

As others have said its normal to be cold feed only these days.

Unless the pipe run from heat source to the washing machine is very short, it won't pull enough water through for anything warm to arrive, hence most being cold fill only

We had a hot and cold fill Hoover machine for donkey's years and our practice was to run the nearby hot tap until it ran warm so that the machine didn't need to heat the water with full price electricity. From my days at Hoover I remember that continental machines were always cold fill and I suspect it was a side effect of being in the European market from early EEC membership that caused the rationalisation to take place. There's not a lot of water in the wash cycle so the cost to heat it is relatively small anyway. Most of the water is used in rinsing.

We used to do the same. Our current machine is cold fill and seems to take a lot of water so I think hot fill would help a bit.

Completely pointless having hot fill on machines these days!

With a gas boiler the cost of heating is about 50% of that by electricity. Admittedly washing detergents are now claimed to be competent at lower temperatures which minimises the benefit but certain categories of laundry still need 60ºC. "Completely pointless"? Not quite. Of less benefit perhaps.

There are no hot fill any more because the design of houses means that it takes a while for hot water to get to the washer drum, which has already 1/2 filled with the cold water preceding it.

Three posts up offers the solution.

What if you plumbed a cold feed washing m/c into a hot feed ? Would it wait for the water to cool ??
I have a BIG cylinder full of Hot water

You'd have an expensive rinse cycle!

Isn’t that a solution that sees you waste the water that has already cooled in the hot water supply pipe and leave more hot water behind to cool after the machine has filled?
