TOMGREEN413 said:l used to maintain them back in the day and pulling the fans and filters was a horrible job, especially if the house had cats n dogs, the dust levels were beyond!!! They also were responsible for lots of breathing problems. Fortunately the last one I serviced was over 20 years ago.TitanTim said:The bungalow I live in was built in 1971 and the heating system was warm air, think it was a thing in the 70s so you had ducting in the floors and walls with grills and a small gas burner. It was an awful heating system being noisy as it relied on a fan to push the air around and was an all or nothing warmth, dog used to like sleeping over the grill in the floor thoughThey were basically just a large fan heater as soon it switched off the temp would drop like a stone.

I mentioned the old heating system when having the boiler serviced back in Feb and the chap said there's still houses on the estate with the original warm air system
