Gas Boiler Repair Tips for Heating Engineers

For repairing a natural gas boiler the heating engineer must first identify the gas inlet pipe and shut off the gas supply at the safety valve.

The heating loops connect to the hot water tank where the water is heated using a coil. There may be more than one of these.  The pressure gauge should indicate between 12 and 15 PSI; anything below 12 PSI can cause problems and reduce the boiling point of the water.

A puddle of water by the boiler can be an indication that a problem with the pressure tank has activated the pressure release valve.

If the pressure is too low, the condition can often be rectified by the use of a manual pressure feed switch. This is sometimes all that is required and further gas boiler repairs may not be necessary.

The control panel on some heating systems can detect problems and shut down the gas boiler. If this happens the heating engineer should check to see if there is an error code to indicate the cause of the problem. One way to deal with this problem is to use the reset button on the control panel and restart the heating system.
