Hello everyone,
I have a general question.
We moved into our new build four months ago. The living area on the ground floor has three large floor-to-ceiling windows facing south. We have underfloor heating and an air-to-water heat pump.
It provides a really comfortable temperature inside the house, but we have a problem – whenever the sun is shining in winter, even if it’s -2°C (28°F) outside, the temperature suddenly rises to 24°C (75°F) in the living room. It gets uncomfortably warm in here, and the underfloor heating can’t be turned down quickly.
Should we assume that the large floor-to-ceiling windows are responsible for the heat gain? A photo of the south-facing side of the house is attached.
What would you do – always lower all the blinds as soon as sunlight is forecast? That seems quite annoying...
We have motorized blinds controlled by Somfy. Would you consider buying a sensor that automatically lowers the blinds at a certain temperature?
Thanks in advance for your replies.

I will check the pipe later.

Is there a pipe connected to the storage tank where you marked the upper green circle? How many seconds does it take until you have hot water at the faucets or shower? I think there is a pipe for that.

chewbacca12323 Dec 2019 21:04I just checked – it was set to continuous operation. I have now set it to a timer with specific times, will test it out.
That should also reduce the kilowatt-hour consumption per day, hopefully…

Daniel-Sp23 Dec 2019 21:17Good move, the circulation pump should run as little as possible. For example, in the evening when the children are showering or bathing. As briefly as possible, but at least once a day!
