We recently bought an older house, and when I tell you it's Baltic I am not joking. It's warmer outside then inside sometimes. Any way, the house is getting wrapped after Christmas and new windows but in the interim any ideas how I can maintain heat in the small fellas room the heating obviously is on all the time but the heat isn't retaining once it's turned off. I have the electric blanket in there & timing the heating on and off during the night, but the condensation on the windows is crazy in the mornings and I'm genuinely concerned he's going to get sick once it gets very cold coming into Xmas. Any tips would be welcome. He's 13 so hes saying he doesn't feel the cold. But my Jesus tids Baltic In there
