Just wondering if there is much work involved in putting in a hotwater connection for a washing machine. We got a new one and there is only a cold water connection there at the minute.
A hot water feed is wasteful and costs more to run.
When I run the hot tap at my kitchen sink I get 6 litres of cold water before it's hot. When I turn off the tap I leave 6 litres of hot water in the pipe unused. Most likely a dishwasher will take in 6 litres of cold water and heat it up leaving 6 litres of hot water wasted in the pipe.
Even if the hot water cylinder is close to the machine the water might be too hot and the machine let's it cool or ads cold water.
A dishwasher or washing machine with only a cold feed is the most efficient type of dishwasher or washing machine. They are A energy rated.
I'm guessing you have solar & are looking at ways to use the hot water. This isn't one of them I'm afraid
