Last zone with heat demand remains open
With the Plugwise zone control, the last zone that had a heat demand always remains open by default. After all, the boiler / heat pump is switched off and no heat flows through the heating system.
This has several advantages:
- Saves batteries with a Tom radiator valve. It is possible that this zone will soon be the first to have a heat demand again. Tom has not closed and opened unnecessarily, which saves batteries.
- Works better for the boiler and heat pump. Some boilers and heat pumps run for a while after a heat demand in order to lose heat. If all radiators / underfloor heating are then closed, the boiler / heat pump pumps against a possibly closed system, which can be unfavorable with some boilers / heat pumps.
Always close the last zone with heat demand (district heating)
If desired, you can adjust that the last zone that had a heat demand is always closed. However, this is not preferred for boilers and heat pumps for the two reasons mentioned.
With district heating and other systems where hot water flows continuously, it is necessary to always close the last zone. With these systems, hot water always flows around, even when there is no heat demand.
To do this, go to settings > heating system > advanced settings > uncontrolled heat source. Turn it on and click save.
