Hello, just purchased a new front loading washing machine. It only came with one water inlet which i plugged into the cold water tap (i have two hot/cold taps). Question is, why only one? My old washing machine had two.???? Does new machines now heat the water automatically via the cold inlet? Pls help????? This is perfectly normal.
It's more efficient for the machine to heat it's own water. Ours only has the cold inlet.
The reason being that since the whole cycle (wash and rinses) uses only about 60L of water, then the actual wash cycle would only be about 10-15L if that, so it's cheaper for the machine to heat that. Also you can set the temp of the machine to upto 95 degrees, so say you are doing a wash with 60 degrees, the Hot Water System would draw the water into the machine at 45-50 degrees, and then the washing machine would still have to heat it up to 60degrees. At the same time the Hot Water System then has to reheat the tank. So it's more expensive. Also more precise temperatures can be gained by the machine heating it's own water.
Stair Designer Rus . Say for example that you want 30 degrees water, it's more precise if the machine brings in cold and heats to 30 degrees, rather than guessing how much hot to mix with cold. I know myself, when we bought out machine 3 years ago, being surprised at only one cold water inlet. But our electricity bill has not gone up noticeably even though the machine heats it's own water, when our old one didn't. There is also considerable variability in how much cold 'hot' water from the pipes is drawn in depending on whether your hot water system is sitting right outside your laundry or at the other end of the house or whether the hot water has recently been run in the laundry, how well the pipes are insulated etc.
This variability becomes more of a problem as the amount of water used by the machine decreases (as pointed out front loaders use considerably less water than top loaders). A better and more consistent outcome will be achieved if the machine heats the water itself. It's got absolutely nothing to do with anything being more economical.
It's about reducing the build price. Removing hoses, filters, solenoid valves piping, is much cheaper with the simple addition of a thermoblock for heating cold water. They may tell you it's more economical but that doesn't' mean it's true. My washing machine is right next the electric hotwater system, as most people's would be as that's generally where the the washing machine and hotwater system are - in the laundry. Electric hotwater systems are connected to a different power tariff, their supply cost is 1/3 cheaper than the plug in power of a washing machine.
And ofcouse gas is a hell of a lot cheaper again. I urge all to think for themselves and not become a product of marketing conditioning and lies. New Washing machines have only one cold water input because they are cheaper to build and save the manufacturer money. They are not more economical. My washing machine is right next the electric hotwater system, as most people's would be as that's generally where the the washing machine and hotwater system are - in the laundry. I beg to differ.
Get to know your appliance with Bosch instruction manuals. Complete documentation is available for all Bosch appliances which includes valuable information about.
The last three houses I have lived in have had it a fair distance away from the laundry, closer to the bathroom which makes sense in my books - a couple of loads of washing per week vs. A couple of showers every single day, I'd rather it be next to the bathroom (or kitchen for that matter). Also, a lot of these machines are from European manufacturers (Miele, Bosch, Asko, etc.) and in a lot of these houses the washing machine is located in the kitchen. Controlling for where the how water system is located is going to be pretty hard. Back to my house - when I fill a bucket full of hot water for a mop or to clean the car or whatever, I would come close to filling an entire bucket (probably around 4L) before the water is up to temp. My Asko uses around 9 - 11L per wash.
