Is hot and cold water put into a washing machine,or just cold and then heated up in the machine?

Answer 1

mine can do either if i press the economy button it takes hot water from the hot water system of my house or if not it only takes cold and then heats it up itself.

Answer 2

Assuming you have a regular washing machine it should be connected to both the hot and cold water. If you put the selector on warm then both hot & cold should go in. If you put it on hot then just hot and cold, just cold. Some machines do have a selector for cold where the machine will warm up the cold water to the best temperature for cleaning. I hope this helps.

Answer 3

Depends on the type of machine.

Hot + Cold fill is better because your house water heating system is likely to run much cheaper than a washing-machine element. This type will also work when there is no hot water available. Cold fill only machines are generally cheaper to buy and are simpler to install.

Answer 4

Originally, most machines only had cold fill. Then most changed to hot and cold fill. Replaced ours last week and couldn't find a hot and cold fill machine anywhere. Searched the net but finished up buying cold fill only.
I dont know why tho. The water heater in most machines uses a huge amount of electricity. I'd have thought it would be cheaper to use water heated by your home hot water system.

Answer 5

I have read with interest all the answers, and they all seem to be correct .if conflicting.
Some are from USA ,some from UK
I will answer for UK only. In the past it was thought prudent to supply H & C to all machines, trouble was that by the time the hot got to the machine the hot was cold anyway.
Manufacturers are now aware of this and are fitting machines with cold only, Also they argue that not all houses have stored water anyway.

Answer 6

That has to be the most ignorant question in this post... Washing machines dont heat the water... That is why there is a hot cold line going to the maching, and different temp settings... Put the maching on hot and let it fill a minute then stick your hand in the stream of water, let us know if it burned you. As far as some machines having onlly one input line being efficient because of a built in heater thats ludicris.. It waste more money heating the water than if you use the hot water that is already there in your home..

Answer 7

had this question yesterday...

(UK answer)

Most modern machine are cold fill only. They haven't made hot and cold fill for a few years.

Go into any high street white-goods shop and you will not find a hotfill machine. "spiko" ( above) has it the wrong way around, no dis intended.

Apprantly its more ecomonical to heat it up internally. Which cannot be true for all applications - our washing machine sits next to 210 litres of redhot water in a megaflo.......Actually, I guess thats the reason, whats the point in bringing in hot water at 70 degrees and cooling it to 30 degrees.

Answer 8

Depends entirely on the washing machine. Mine is a cold fill and is not hooked up to the hot water tap in any way. I think most new washing machines have cold fill.

Answer 9

The washing machine is hooked up to a hot and cold faucet. When the machine is turned on using the Hot setting, it automatically uses hot water. Next time you wash, turn it on and you can see that it comes out hot.

Answer 10

the back hoses on your machine are hooked to a cold water and a hot water connection. you choose cold, warm and hot and it comes into the machine already at that temperature. the machine does not heat the water.

Answer 11

You can buy machines which use either system though the trend these days seems to be for cold fill only with internal heating. I have a Bosch which has just the cold water supply and it works very effectively. Easier to connect up too, with only one supply - and you don't have to have a separate hot water system switched on either!
