Our house has cast-iron radiators, so when it’s very cold out, the boiler runs for a while and the radiators get very hot and continue to radiate warmth into the room. But when it’s just a little cold out, the boiler doesn’t need to run as long, so the radiators don’t build up a lot of heat.

Why is my house hot when it’s cold outside?

When your room is hotter than the outside, it’s possible that the room has poor ventilation. Proper ventilation allows hot air to exit while cool and fresh air enters the room. South-facing rooms also heat up from more sunlight, while upstairs rooms will experience the Stack Effect as heat rises through the building.
