Wood burners/fire places not enough to keep sims warm
If you have ever spent time in a house heated with wood burners and fire places you know they can get pretty hot. Still, in the Sims4, sims keep need a thermostat heated house to take off their outdoor clothes. Irl one wood burner centrally placed in a small house heats up the whole house including the top floor as heat rises upwards. I live in a country, Sweden, where a lot of people heat their houses with wood burners. In a bigger house it's usually enough if a wood burner/fire place is placed in each end of the house to heat the whole area. Absolutely not in every room.
Please make fire places and wood burners adequate for heating a house so that the sims4 can change into everyday clothes. This will be great also for offgrid lots, old castles etc which are heated this way. Don't make it necessary to have a wood burner in every room, that is not a reality. Have you ever seen chimneys go up on the roof from every single room? No, one in small houses, 2 in big houses and 3 in huge houses is enough. Maybe make a red big circle around every wood burner/fire place in build mode at placement to show how big the area is that it will heat.
I also have a suggestion regarding the AC unit. Over here where I live those are common although I live in a country where the winters are cold. That is because they work both for heating and for cooling (when set to run in reverse). As they are so common for heating houses in the north, please make an option to choose heating or cooling when clicking on the AC unit. Same with them, one rather centrally placed is often enough to heat/cool a whole house but a bigger house might need two for each half of the house.
