Heat helps bacteria grow. Ever had surgery and notice how the surgical room is so cold? Keeping a room too warm will only help the spread of any bacterial bugs that come into the house.
If you are comfortable, the pigs are perfectly comfortable as well. Give them a couple cozies or something warm to snuggle in.
Make sure the heat lamp, if you decide to keep it in the cage, is higher than the cubes. I have pigs here that stretch up and can reach up a few inches over the cubes. I'd hate for any of your pigs to suffer a burn. We have a reptile guy that comes into speak at our school every quarter, he's brought in a few reptiles that have lasting burn wounds on them from those bulbs.
