What are Gas Boilers? 

Gas Boilers produce hot water and heat the home, like mini fires. These central heating systems continuously heat water, pump it through pipes and radiators, spreading heat around the property to heat the house. The hot water is either pumped to taps and showers directly, like in the combi boiler or stored for future use in a water tank. The boiler works on either bulk LPG, stored on-site, or on the on-grid gas. This gas is then burned in the boiler’s combustion chamber that raises the water temperature to around 70°C using a heat exchanger.

●        Diaphragm expansion vessel – these are pressurised water vessels to expand and absorb water pressure that surges during heating

●        Exhaust Pipe – it is usually a thin plastic pipe pulled through the chimney to remove traces of carbon monoxide produced as a by-product of the gas boiler heating process

  1. Re-pressurise your boiler - First, make sure to turn off the boiler, and check if the end of the hose is attached to the valves. Now, look at the water pressure indicator on the front of your boiler. If it is below one, then the boiler pressure is too low. Open the valves until the pressure indicator reaches 1.5. Close the valves and switch the boiler back on.
  2. 2. Resetting your boiler - Press the Reset button and push it for 10 seconds. The boiler should start working again after a few minutes. Repeat it the second time if the first reset doesn’t work.

After seeing the problematic radiator, turn off the central heating and turn the radiator key anti-clockwise to allow the gas to escape. You should hear the pressure leaving the system. Close the valve once all the gas has escaped.

What Causes Low Water Pressure?

Low water pressure can occur when the water is not constant. The demands during busy morning and evening periods may reduce water pressure in the mains network.   Low pressure can occur when the pressure in the water main is not enough for water to reach the top of the house. A significant drop in water pressure can be rare and may only happen in the event of an emergency, e.g. a burst water main. How Does Water Pressure Work:   The water provided to your home is pumped through a series of underground pipes from the water treatment centre. Once in the house, the water will generally flow to water tanks placed at elevated heights such as in the loft. Gravity induces pressure, so, by the time the water reaches your taps or showers, the water should be at full force. In certain situations, the water pressure maintained across the water lines through the use of booster stations. The water tank in your home will keep the water pressure within a specific range. The ideal range of ...
