Just moved into rented flat but completely puzzled by the water heating, perhaps someone can put me right.
The place has a Tempest water tank and two immersion heaters, one wired into something called O/P Immersion and the other wired into something called N/T Immersion. No one seems to know what they mean or what I have to do to maintain a good supply of hot water without running up horrendous electricity bills.
Is there anything I can do, DIY like, to make changes?
