That's what I was worried about. But doesn't fifteen litres storage mean it's going to have to be on, heating water all day, just so people can wash their hands when they want? Isn't that going to be really energy inefficient?
Hi, thanks for reading this, hope you can help!
Basically we've had a bit of a nightmare with the plumber we chose and have had to rip out all the work he did because he used the wrong pipes etc.
We now think he may have given us the wrong info about the hot water heater he was going to...
