Why is my boiler not giving me hot water?
Low pressure may be the reason for your lack of hot water. For your boiler to work at its best, your ideal water pressure should be between 1 and 1.5 bar, which is usually displayed on a gauge known as a ‘Manometer’, usually located where the water supply pipes are connected to the boiler.

Would a boiler explode?
While historically, boilers would over-pressurise and explode with alarming regularity, modern boilers are manufactured to be able to withstand excessive pressure, and can typically handle an operating pressure of 20 PSI. When pressures increase beyond this level, the boiler can fail, which can lead to an explosion.
Can a hot water heater catch on fire?
