Hi, looking for any suggestions that might help me here. Moved in to a new house a couple months ago and have noticed that the water in the water cylinder is always hot no mater if the heating or immersion is on or off.
For example the other night I went to bed:
Boiler was set to 0
Heating switch was set to off
Termostat was set to 0 degrees
immersion switch was set to off, with no red light on
When i got up the next morning, water tank is still hot and hot water is coming out of the taps.
I had the boiler serviced today and said it to the chap, he was an Airtricity callout though and hadn't a clue unfortunately.
I'm afraid it's costing the energy bills a fortune. Any ideas?
