Answer 2

My parents have a wood/coal fire. They have the chimney swept twice a year because the wood causes a resin build up, and the coal leaves soot in the chimney which blocks it. Years back I remember trying to finish my homework as the fire brigade were putting a chimney fire out (that was the before they had regular sweep visits!). Also, depending on which way the wind blows, they get 'smoke blow backs' into the house. Usually when all the doors are shut! So good ventilation is a necessity.
There are a lot of UPVC cleaning materials for the frames, it's a hazard of having real fires!. Keep warm.
