Domestic vs commercial boilers

In general terms a domestic boiler has a range up to and including an input of up to and including 70kw net. Above 70kw net the installation is considered to be commercial. For example if you had a 70kw net boiler this would be deemed to be a domestic appliance but if you had two 40kw boilers connected to the same system, this would then be classified as a commercial installation because the total net input is greater than 70kw.

Maintaining a commercial boiler

It is important, not only to comply with legal requirements, but having invested in equipment that should serve a good number of years, to remember the importance of regular maintenance. Any gas fired apparatus should have regular maintenance carried out by qualified and certified personnel to ensure the best running conditions and reliability of the plant. The law requires that such gas fired apparatus should be serviced in accordance with the manufacturer’s instructions at least once a year. In some cases, servicing can be more frequent dependant on the environment and the duties imposed on the plant. We recognise that each customer has their own needs. Some prefer to have an informal approach and contact us on a yearly basis for their annual maintenance.

Others prefer a more a more comprehensive and contracted arrangement. Either way we are pleased to accommodate and tailor our services accordingly. For further information or if you need an estimate please contact us.
