We have a extremely old boiler in our rented accommodation. It basically uses gas to heat air and blast it round the house, and uses gas to heat the water. The hot water has no timer so I have to manually light / extinguish the gas light. I've noticed burn marks around the funnel (where the gas burns and blast heat upwards) and today I noticed that the flames are rolling out of the funnel occasionally.
We're due to get the boiler replaced but should I be pushing for this to be done sooner rather than later - I've never had one of these boilers before so I'm not sure if it's in the realms of normal?
