So I have a gas geyser, and usually in winter, when turning on the hot water tap, sone gas bleeds for a while then it ignites the flame. I've noticed that this only happens in winter. Problem is that when it bleeds, and the flame is ignited, there is an explosion of some sort every time.
Now with an explosion, it obviously affects the air in the room, there is some pressure/force or whatever and the result is that my ceiling cornices become loose. I replaced my bathroom ceiling twice within a time period of 4 years. The cornice nearly fell on my head this morning.
Is there perhaps a strong ceiling board and cornice that can withstand this problem? Does anyone experience the same type of explosion during winter?
