Do washing machines use hot water or heat cold water internally?

Question

Really just want to know if the use of the washing machine contributes to my gas bill or just the electric!

Answer 1

Depends some use hot water from the tap and others heat cold water, you can tell which is which by checking if your machine has a hot and cold or just a cold connection.

Answer 2

They usually have a hot and cold feed.

All washing machines have a heater to heat the water to the temperature that you have set the machine on. The cold water will cool supplied hot water..if too hot..

Now if your hot water is not up to temperature you will use electricity via the machine to heat it up and the whole wash cycle will take longer. But if your hot water is not on timed hot water but on constant hot water your boiler will be using gas trying to catch up to speed. So you need to look at the whole thing

As gas is less expensive, I always make sure that the water is piping hot before I start a wash..the whole cycle is quicker and I perceive you use less electricity.

Answer 3

Yes they do. The newer ones are cold fill only and heat the water to the correct temperature for the wash selected. The older ones were hot and cold fill and they took the hot water from your domestic hot water and mixed with cooler water if needed and heated if water was not hot enough. In USA/Australia/Canada and New Zealand their washers do not usually heat the water - they only use the domestic hot water (which could have been run cold from a lot of showers etc.).

Answer 4

Water enters a building structure via a main water line at a cold temperature. This cold water then branches off through water pipes that are constructed throughout the building. One such pipe leads to a hot water heater or boiler. If working properly, the hot water heater/boiler distributes hot water through a pipe to the destination in need of hot water at that time ie. washing machine. The hot water heater can be set to deliver hot water at varying temperatures. Without a hot water heater/boiler, a washing machine will only be able to wash at a cold water temperature. The hot water heater is also connected to the gas line. thereby, gas usage results in an increase in gas bill. You may want to consider washing more often with cold water. Also, keep in mind the other uses you have for hot water ; bathing, cooking and dish washing.

Answer 5

Depends on the machine and how the hot water is heated in your home.

Most older and even new machines have dual connections to the hot water and cold water and draw each for "warm loads", hot only for hot, cold for cold rinse, etc.

So if your machine matches that configuration, then it depends on whether or not you have a gas hot water heater. Otherwise, or if it is one of the newer machines that heats internally, all electric.

Answer 6

Every washing machine I have ever seen or owned has had two separate water hoses....hot and cold. Obviously, the hot water used by your washing machine uses hot water supplied by your hot water heater. They do not heat their own water. It could probably be done, but it would really slow things down while the water was heating.

Answer 7

It depends on the model of washing machine you have... If it's connected only to the cold water pipe, it contributes only to your electric bill, as the water will be heated internally. if you have one of those who are connected both to the cold and the warm water pipe it would contribute to your gas bill, as it already takes warm water directly from your circuit. ;)

Answer 8

They often use both, as most people have said; if yours is plumbed in to the hot and cold pipes at the back it will use the hot water unless that runs out; then it will use the built in element to heat the cold.
They only use a mix of hot and cold to wash, they use cold to rinse.
If yours has a manual on/off switch (clicks like a light switch, not an electronic switch) then its worth getting Economy 7 put on and running it after midnight, using a 24 hour timer switch. You get 3 nightime loads for the same price as one daytime load.

Answer 9

Most new machines only have a cold water feed at the rear so the cold water is heated to the correct temp making them more efficient

Answer 10

most modern washers use a cold water feed and heat it internally during the wash cycle, though this may seem more expensive it generally works out a little cheaper for some odd reason, probably because washing nowadays is done at much cooler temperatures than it used to be. ie 40 degree wash
