We bought a house last year and the only heat source is an electric baseboard heater. We have to keep it on at least 24/7, since we don’t have central heating. The problem with that is there’s no place around the house where I can open doors or windows without having cold air immediately enter the house from outside – I’m talking all day long! In addition to being extremely inefficient, it makes everything in our home very damp and moist because of all the condensation from the water dripping off toilets onto everything else. Any ideas about how to prevent this?
