Good day,
first some data about the timber frame house: Kfw 70, heated area (including parts of the basement) approx. 200 sqm, underfloor heating everywhere, brine heat pump, controlled residential ventilation/heat recovery, consumption in 2012 approx. 2500 kWh, location cold region.
I am now considering whether a slight night setback might bring a consumption advantage, even if this is small. I was thinking of a night setback of, for example, 9:00 pm to 5:00 am by 1 degree, controlled with respect to the target return temperature.
What do the experts among you think? Are such considerations worthwhile? Or does the increase/compensation of the target return temperature reduced by one degree in the morning ultimately cost more energy? Are there any experiences/opinions/calculation examples here? Effects on the heat pump, source?
A significant night setback is probably less useful.
Best regards
