I have to set up a new connection point for a washing machine.
Is is worth providing a hot input for washing machines any more ?

My current machine I have a Y connector connecting hot and cold inputs to a single cold supply. With a combi boiler the machine would rarely get any hot water anyway.

Cheers,
Simon.

My last 2 machines have been cold fill only, so I guess not.

I have not seen a hot supply for a washing machine on a new build in the
last 15 years.

Don't bother IMHO.

I wouldn't bother unless the pipe run from the combi is very short,
and the combi supplies hot water very quickly, and it was little
effort to connect it.

Like everyone else said, new machines don't have hot fill anymore
anyway, so you won't need it after this machine is pensioned off.

Indeed, part of the reason for the change. Also modern machines use very
little water, so quite often will be about full by the time you have
drained the dead leg on the hot pipe!

Many machines also start off with cool water, and then heat it as the
wash progresses to allow the clothes to pre-soak without setting any
protein stains in hot water before the powder has chance to shift them.

Machines are generally cold fill only now because most washes take
place at 40 or even 30C, cooler than a decent ho****er supply, even
that from a combi... I think the emzymes get destroyed if they even
briefly come into contact with hotter water.

That's correct.

My old Hotpoint had the intelligence to start with cold, and then
mix in hot to get to an initial 30C max. It would switch hot and/or
cold feeds on and off under microprocessor control.

My new machine uses significantly less water anyway, and the amount
of hot needed to do the same thing would be miniscule, so it has
no hot feed at all.

That's the first time I had heard of that (and others here have
confirmed your comment).
Useful to know.

Unless their design changes no point in any of that including putting them
together. many machines seem not to like hot water and just sit there if its
over the temp for the selected wash.

Some old machines did a hot-only fill for the hot washes (60C, 90C),
and if you don't connect the hot inlet, they won't be able to fill.
Depends how old the OP's current machine is (and if the OP ever uses
the hot washe programmes). Today's detergents will work better with
cooler initial wash anyway (no more than 35C), even for a hot wash.

Only really a good idea where the machine is located next to and fed by a
combi boiler so the hot water arrives straightaway. I'd be suprised if the
detergent drawer etc were designed to cope with hot water. I know a couple of
cases where people have created a "warm" connection for their washing machine
by using a thermostatic mixer set to 30 degrees in conjunction with a nearby
combi. I wouldn't set it any warmer than that.

Complete waste of time. I haven't seen a machine that takes hot water
in years.
Back then wwhen there were, it was a complete waste of time, most of
the water that went in was cold anyway from the standing water in the
pipe.

Yes, but... I'm allergic to enzymes; they make me itch, so we use
non-bio powder. Towels and sheets, in particular, don't feel right
unless they're washed at 60C (though it doesn't bother my wife) and
don't get me started on on fabric conditioner which should never be used
for towels (it makes them waterproof!).

Perhaps it's just my fad but I like the feel of pure cotton, simply hot
washed. I sometimes wonder if the prevalence of nits is because
low-temperature washing doesn't kill them and their eggs.

Does that mean they use warm water for all the rinses?

To turn the question on its head - it is very hard to find a current w/
m WITH a hot fill option.

Domestic ISS 10yr £899 has hot-fill "for solar usage".
I am not certain hot-fill works due to the small volume of hot water
used against the initial "cold volume". The pipe run would need to be
short, well lagged.

Launderettes conversely do use hot-fill, supplied by several thermal
stores off a big gas boiler.

We've done a 90C wash occasionally to clean the machine out, and it has worked fine with just a cold fill, connected to both hot and cold inlets.

Oddly enough, fabric softener should never be used on water-proof or
-resistant clothing because it *reduces* the resistance.

For hygiene, I think it's a good idea to wash bedding at 60°C, and
towels at that temperature at least some of the time.

The manual for our current washer-dryer recommends using the 95°C
programme once a month to blast any cack out (paraphrased).

I guess so. I suppose it means the clothes will air dry a little quicker...

Its about washing machines in general, not a particular model. As someone on the thread said, new builds now don't supply a hot connection for washing machines and most new machines apparently dont have a hot input.
So I'll save a few minutes plumbing up a connection that will never be used.

Cold supply only gets them a higher energy rating. When yo think about
it the most energy efficient [1] way to heat water is by an electric
immersed heater.

A couple of years ago I gave my old wachine machine to a friend who had just
moved into a new build and she could not afford a washer. When I asked on
this group what to do with the hot inlet the consensus on the group was to
split the cold supply with a Y connector to feed both the hot and cold
inlets. Doing this served two puposes. It would stop water coming out of the
hot inlet (although that should not happen) and it would allow water into
the hot inlet if the machine demanded it.

I have a 10 year-old Bosch that has both hot and cold supplies - it works
very well with a Combi boiler. With my normal cool wash (40C) it alternately
uses hot and cold to fill to the required temperature. No electricity is used
for heating the water which must be more economical, surely?

The washing machine and the boiler are in the same room so I know when the
combi is firing. When it's filling, the WM uses hot water for a bit (boiler
fires), then stops and continues with cold (boiler doesn't fire).

I was told that the time taken to heat the cold water coming in was part
of the timed cycle so a hot connection would seem to circumvent that.
