>Back home, we had electric accumulative heaters. The power was cheaper overnight, and between 12:00 and 15:00, so these would crank up the heaters and would warm up heavy bricks around the hot wires - when it was cheaper. Then when it went higher rate, these would shut off, and only a fan would blow the air through the hot bricks and thus distribute the accumulated heat.

I knew about the fan ... as in when the s..t hits the fan



We also have cheaper electricity
(1) day - most expensive
(2) if you install another meter, you can capture the pulse. It then switches to the other meter (21:00 >> 06:00). At about 06:00 it receives another pulse to switch back to the day meter (1)
All electricity is then a bit cheaper
(3) only night (21:00 >> 06:00). They only supply the electricity between those hours. That is used for the brick-electric-accumulative-heaters (also three phase). Got some of them too

Didn't know about the boiler. I have a clock on my water heater. It switches on at 21:15 an switches off at 05:45 so that I can use (2)
