Gas boilers are designed to heat water flowing through pipes that pass through the rooms of the house with steel radiators or cast iron radiators. If you're not sure which one you have, keep in mind that newer homes usually have steel radiators, while older homes have heavier and bulkier cast iron versions, unless, of course, the homeowner has replaced them. 

Boilers can use natural gas, propane, or fuel oil, also called naphtha. Although gas boilers courses are quite complex in terms of components, they tend to be reliable and require very little or no gas maintenance. 

As mentioned earlier, boilers don't require much maintenance, but when something happens, one of the following problems usually arises: boiler not generating heat, poor heating performance, excess water, insufficient air and water leaks, to name a few. To prevent this problem, regular annual maintenance of gas boilers should be scheduled. Due to the complexity of the system, it is always best to hire a qualified and registered heating installer to perform maintenance.

What is included in the gas boiler service? It checks whether the heating system has been professionally installed and complies with current regulations. They also carry out tests to ensure that the boiler is working properly and safely according to the manufacturer's instructions prior to departure.

Gas services usually do not include a gas safety check and this must be done by the landlord or landlord. The duration of a service call can range from 30 minutes to over an hour, but depends on how much work has to be done during gas service.
