A well-designed underfloor heating system uses the self-regulating effect in such a case, so that the heat pump does not become less efficient. Yes, the temperature in the house will rise. From maybe 21 to 24 degrees Celsius, depending on the construction method. This is perceived as pleasant radiant heat and does not necessarily have to be ventilated out.Well, the place is warm even without the fireplace. So the additional heat is actually too much. Or do you want to freeze beforehand? After all, the temperature increase is buffered. But because of this, you have to turn off the underfloor heating and the screed starts to cool down (warm air rises), so the actual heat storage mass of the house then requires the heat pump to do extra work through a temporarily increased flow temperature. A maximally efficient underfloor heating is not regulated and runs continuously. Day and night. The fireplace slightly reduces the total heating demand from the heat pump but makes it less efficient over the year. And it still gets too warm when using the fireplace. Therefore, you partially have to ventilate and increase the heat pump heating demand again. There are now artificial fireplaces that you can't tell apart from real fireplaces. And they don't cost 10-15k€. If the wood is not sufficiently dried, wood even releases more CO2 than coal. There's also fine dust delivered free of charge. We simply have to stop constantly burning things and a fireplace cannot be sugarcoated with reason.
