ᐅ The children's bedroom is too warm in the new build.

Hello everyone,

We have finally been living in our newly built house for two weeks now. We have underfloor heating throughout the entire house and a digital thermostat in every room. All thermostats are set to 21 degrees Celsius (70°F) throughout the house, and everything works fine overall. As soon as the thermostats reach 22 degrees Celsius (72°F), they switch off—except in the children’s room. There, we have noticed that the temperature easily rises to 23 degrees Celsius (73°F) overnight, and the floor remains constantly warm compared to the other rooms.

I have already contacted the company that installed everything for us, but it will probably take some time before I receive a response. As a curious person, I would really like to understand what could be causing this or what the reason might be.

Best regards

Is it too cold anywhere? If not, lower it slightly again and wait another 24 hours.

In the guest bathroom, the temperature does not rise above 21°C (70°F) even though the floor feels noticeably warm. I suspect that cold air is entering the room through the Lunos ventilation system.

Does the bathroom only have underfloor heating?

It could be coming from the ventilation, but that wouldn't help. Is the valve in the bathroom fully open?

Maybe your guest bathroom is the room that determines the supply temperature. This makes sense because there is only a small amount of heating surface. You could heat the surrounding rooms more if they are significantly cooler: hallway, utility room, or whatever you have there. If the supply temperature can be lowered significantly without the guest bathroom, then you need to consider how important 21 degrees Celsius (70°F) versus, for example, 20 degrees Celsius (68°F) is there.

When adjusting, it’s better to open valves in the colder rooms rather than throttling valves in the warmer rooms, so that a high overall flow rate is maintained.

Or the area simply isn’t sufficient to heat the room more effectively.
If the flow rate is already fully opened, your only options are to increase the supply temperature overall or to accept the current situation.

I don’t know how long your sessions in the guest bathroom usually are, but I think 21°C (70°F) is warm enough and wouldn’t worry about that room.
