Washer dryer - h&C inlet - use only one

Jan 24, 2006 39 Replies

I am buying a washer/dryer with hot & cold water connections. Unfortunately I only have a cold supply - will it be ok to put a Y piece in the cold supply and split it to both h&c inlets?



Erm! Nurse.

No you cant.

-- Sir Benjamin Middlethwaite

Yes. I would advise doing this even if you had a hot supply available.

Do whatever it says in the instructions - bound to mention it. I'd assume you simply connect the cold & blank off the hot.

No I would'nt do that as some cycles call for hot only and if you'ved blanked that off the inlet it will sit there wating for water and possibly damage the hot water valve as it will stay on till switch the machine off. Connect cold to both hot & cold inlets and allow the machine to heat the water to the required temp. Trevor Smith

They almost invariably tell you to supply cold to both inlets. They often even supply a Y-piece in the box for this purpose.

More modern machines have only cold fill, as modern machines use so little water that by the time the hot comes through the pipework, the machine is already full, so it was a waste of time.

On 40C washes, which are the most common programmes these days, it might not even attempt to draw hot even if it has hot fill available.

Christian.

Can i ask why you have no hot water?

-- Sir Benjamin Middlethwaite

If you do that and set it on hot wash it will open the blanked-off valve and sit there forever waiting for water. If you tee it off the cold feed it will fill up okay, and then heat to the required temperature anyway.

That rather depends on how long the dead leg to the machine is. If this is short then hot water will arrive almost instantly.

Some relatively modern washing machines seem to take as much hot water as possible, blending in cold if necessary to reduce the temperature. That seems very sensible.

Why say you can't, when of course you can? Did I miss a joke?

Yes you can!

Mine has been like this for the past 20 years and works just=20 fine.

I have got hot water, just don't have any where I want to put the washer Thanks for all the replies.

The Nurse has just been and she gave me a good seeing to!

So therefore your electricity bill will be high depending how often you use the washing machine.

How many watts is a heater in a WM? chaps.

-- Sir Benjamin Middlethwaite

Often 2.2kW.

In a modern machine it isn't on very much, as it doesn't heat much water.

Christian.

You an buy longer hoses, you know.

-- Sir Benjamin Middlethwaite

Besides, the majority of washing is done at 40C these days. Much hotter, and you will destroy the enzymes in a biological powder. These are most efficient at 37-40 anyway. Many of the latest machines seem to be cold fill only, I guess partly for this reason.

Thats a lot of money wasted? why heat water within the WM when you already have HOT water?

-- Sir Benjamin Middlethwaite

I'm sure you're going to give a good reason for the above, but how come? I'd rather the hot water was heated by my gas boiler than full-price electricity.

David

Oops, replied too soon: you answered this elsewhere...! Personally, I always run the hot tap in the adjacent sink until it gets warm, before firing up the washer (still trying to train SWMBO to do so). But even without that, I don't see why it's *better* to connect both inlets to the cold supply.

Typical modern machine uses 50-60L of water. The vast majority is cold water for rinsing. Typically what will happen with hot fill is that the majority of the 'hot' water used to fill is actually cold. You just wind up heating the pipes. So you pay twice -- once to heat up the replacement water in the cylinder or whatever, and agin for the washing machine to heat up the cold water you've just put in it.
