i need to know if a uv flame detector is better than a infra red detector because with the uv sensor i keep having to replace them every 2 to 3 months i get 5.0 readings when new then it starts getting lower readings to the extent of shutting the boiler down on flame failure im keeping the tube clean and the eye clean also thanks
