Hello all, I am looking to replace my old Radiant gas fire with something a little more modern. Ideally something else gas-based as I'm not a fan of the fake flame electric fires. The existing one looks like this: http://www.bhl.co.uk/images/products/64847/detail/valor-brava-4-oxysafe-fire-teak.jpg , there is no chimney in the house so I'm guessing the existing fire vents through a pre-cast flue (there is a small plastic chimney/vent on the roof above the wall where the flue would run). I've heard that there a number of issues associated with these flues, particularly if installed in the 70's (which was when the house was built), and that I may be limited in the choice of fire I can use as a result. I am also considering building a false chimney breast where the fire surround is currently, so would also need to consider this as part of the requirements. Can anyone give me any advice as to my options? I'm not looking to spent a huge sum as this is likely to be for occasional use rather than the main source of heat for the room.
