We viewed a house last week that we really like. We did notice that almost every room had a plug in portable heater of some kind. They weren’t switched on though. The house has central heating and lots of new looking radiators, the central heating was on and the house felt lovely and warm while we were there. But my husband is worried that the portable heaters being there is a bad sign, that there must be something wrong with the boiler, or the house has got damp or something . We were told that the owners don’t live there full time.
