The importance of boiler and water heater commissioning and maintenance

The importance of boiler and water heater commissioning and maintenance

Date: 11th September 2020

Many boilers will have been out of action for some months during the coronavirus lockdown, and with imminent cooler weather a certainty, and the reopening of businesses and institutions already underway, now is a perfect time to consider the importance of getting your boiler checked.

Modern gas-fired boilers and water heaters are designed with energy conservation in mind, with many products achieving efficiencies from 95% and even higher. System design and control are also important factors if high levels of efficiency are to be realised in operation. Two further elements, which are sometimes neglected, are ‘commissioning’ and ‘maintenance’ both of which are crucial in terms of system efficiencies and for other important reasons.


The commissioning procedures carried out by our experienced service technicians include various tests designed to ensure that boiler or water heater installation works at the expected high levels of efficiency. These initial ‘set-up’ tests can also identify potential issues, allowing them to be quickly resolved and save considerable money and heartache in the future and provide peace of mind for building owners and occupants.

The same benefits apply to re-commissioning of such equipment, which may have been out of use for a period of time, as may have been the case with many businesses during recent months.


Most of the benefits of product commissioning also apply to regular maintenance, and as with many mechanical products, evidence of a good service history is a warranty requirement. Routine maintenance can also identify problems that were not apparent at commissioning.

For example, any problems caused by poor water quality. This is a particularly important aspect for direct gas-fired water heaters, where even a small amount of scale build-up can cause a disproportionate reduction inefficiency. If left untreated it can also result in premature failure of key product components.

DRS are happy to assist clients by providing service packs for various products; these include parts, which should be replaced during an annual service. Our Service technicians can also carry out a routine maintenance visit if required.
