Hi,
Can any one help me?
I moved into my house 2 years ago and was always surprise that we didn't need to put our water timer on for long but always had hot water.
Now over the last 3 month due to the hot weather we haven't had our water or heating on at all but still always have hot water. The only way to turn it off is by the mains switch. As far as I'm aware we don't have an amursion button. We have a large water tank on our top for and what I take as a gas boiler (which is set at 5) next to our timer on our first floor (townhouse).
Any Ideas?

I would ask the question in the plumbing dept,, this is hvac,although I`m sure someone will come along sooner or later that can help you
