The dehumidifier warms mine up too.

A basement basically has a R value = to O. Should stay pretty constant. When AC isn't running I notice mine heats up a bit due to a dehumidifier.

Ours also heats up from the furnace and the dryer.

Normal. Basement is surrounded by soil (vs. air) so it's less susceptible to temperature swings.

In our house our basement is often warmer because the boiler in the basement puts off a fair amount of heat.

This makes sense now that I think about it. Thanks.

I thought basements were always cooler than the main and upstairs levels of homes. We've been in our current home (1970s era) for almost a year and that seems to have been the case for this calendar year. During the hot temperatures this year, the basement was regularly 2-3 degrees cooler than the rest of the house. Now with the milder temperatures, and the a/c not running as often, the basement is 2-3 degrees warmer than the rest of the house.

I'm not complaining because it makes the basement pretty comfortable (you don't have to wear a sweatshirt like usual) but I've never been in a home where that's the case and I'm curious if anyone else has experienced this?
