If the pressure is lower than this, the boiler won't work and you won't have any hot water or central heating. Low boiler pressure is one of the most common boiler problems and it can have many possible causes.
Read MoreSystem and heat only boilers will continue to heat up the radiators, and you might even get a bit of hot water out of the cylinder, but that will dry up pretty quickly when there's no pressure or new water entering the system. Unless you turn on a hot tap, the system will carry on running as if nothing has happened.
Read MoreThe improper warm-up of a steam boiler is one of the most severe hardships a boiler must endure. Going through the cycle of start-up, operation, and shutdown for any boiler creates higher equipment stresses and, consequently, much more maintenance-type issues than continuous operation at maximum rated capacity.
Read Moremodule will modulate and shut down the boiler if flue gas temperature gets too hot. This protects the flue pipe from overheating. 7. Boiler outlet temperature sensor This sensor monitors boiler outlet water temperature (system supply). If selected as the controlling sensor, the control module adjusts boiler firing rate so the outlet temperature is
Read MoreModern gas and oil boilers tend to be very reliable, but occasionally they may need to be reset. For example, your boiler might shut off because of a fault that prevents it from working effectively or safely. In cases like this, it's useful to know how to restart the appliance so that you can get your heating and hot water back.
Read MoreThe solution there is to bleed the radiators to allow the trapped air to leave the system. If your central heating system is still not turning on, despite having hot water, it may be that the boiler or heating system is faulty. A Gas Safe registered engineer will be able to investigate the fault and find the source of the issue.
