Why this happens
Although different rooms are controlling an maintaining the same temperature, you feel warmer in one than another.
The interesting thing about this is understanding that rooms need to be at very different temperatures to have the same perceived comfort levels. People often set each room to the same (for example 20ºC) in every room initially. Then they find that the kitchen is too warm at 20ºC and the living room is too cool at 20ºC. The bedroom is too warm at 20ºC in the evening but not warm enough at 20ºC in the morning. What is happening is that we just all want the rooms to be a different temperatures depending on what we are doing. In rooms where we are active, we want them cooler. Rooms where we are sitting down, such as studies and living rooms, we want warmer.
Rooms can also have differences caused by droughts from windows or doors making them cooler in that part of the room, or solar gain from sitting in the sun making you feel warmer. The great thing about zoning your home is that you can now have just the temperature that you want in every room. You may have to experiment a little to get just the temperatures you want.
- Temperature close to the target temperature but the boiler does not come on or the boiler stays on
- Turning The Genius Hub Off In The Summer
- Rooms feel like different temperatures
- Boiler is firing when the heating is turned off
None of the rooms of the house needs heat, all of the heating zones on the app are blue, but the boiler is still firing unnecessarily. Some combination boilers (made by companies like Vaillant and Worcester Bosch) have a setting where the boiler could be set to maintain hot water in the system for the taps. For example, this boiler can have two programs, one for heating and one for hot water built into the front of the boiler. The heating program needs to be left on 24/7 as this is being controlled by the Genius System via the thermostat terminals on the boiler. However, if the hot water timer is left on, it will cause the boiler to come on intermittently during the day because a thermostat in the small hot water cylinder in the back of the boiler is triggering the boiler to make more hot water. When this timer is turned off for the hot water the boiler will stop turning on intermittently to heat this water, but the boiler will still provide hot water on demand. Many boilers have an overrun feature whereby the boiler continues to run after the heat demand has been satisfied. This is to distribute the hot water around the system both to areas where the hot water may be needed and to reduce the temperature of the water in the boiler.
