I've just had some bathroom taps replaced which necessiated draining down the hotwater tank.
Now I've gone to heat up the hotwater but the boiler does not ignite. I tried the central heating (turningup to 30C) and the boiler does ignite and heats up the radiatiors. Any ideas as to what's happened.
I've tried contacting the plumber who installed the taps but am not getting a reply at the moment.
I've switched on the electric immersion (never had to use it before) any ideas how long it will take to heat the tank?
