Our Services

Commercial Gas Installations

New LPG installations are growing rapidly in popularity for commercial and industrial businesses as local environmental issues, particulate emissions and New Zealand’s commitment to agreements such as the Kyoto Protocol play an important role in business planning. In addition, the cost efficiencies inherent indirect-fired gas equipment are now being given higher priority in new commercial building projects.

A number of businesses are ‘future-proofing’ by having gas pipework installed at the construction stage. Investment in gas reticulation networks continues as gas is seen as a clean, cost-effective, and low-carbon fuel. Businesses are seeing LPG as a strategically sensible choice for improving operating costs and as part of their contribution to a cleaner workplace and commitment to a cleaner environment as we transition to a low carbon future.

Gas Engineering Services has a team of experienced gas fitters enabling us to assist with most gas fitting requests from the largest industrial bulk tank liquid LPG system to your typical residential installation consisting of water heater, hob/oven, gas fire, and the odd BBQ outlet. We have established ourselves as the leading gas installation company in the South Island and continue to build on our strong working relationships within the construction sector.

Our extensive knowledge base has us working closely with professional consultants to design efficient and safe gas systems for schools, universities, retirements villages, industrial processing plants, and retail food tenancies, right down to domestic installations.

Whatever your gas requirements, we aim to meet your needs and exceed your expectations.

Equipment Servicing

Scheduled servicing of gas installations and equipment reduces disruption to the business from breakdowns and ensures optimum working conditions are attained, providing peak operating efficiency and cost-effectiveness.

The importance of having a properly maintained energy system should not be underestimated. “If a system is properly maintained there are fewer unscheduled interruptions, reduced emissions and an overall reduction in operating costs.”

Gas Engineering Services offers our clients a scheduled maintenance programme of LPG facilities, boilers, burners, and equipment that is tailored to your individual needs. “We service everything from water heaters, school laboratory systems, commercial kitchens, industrial processing plants, and bulk storage sites We also provide maintenance and emergency response for bulk facilities and gas networks for the major energy suppliers. We welcome your enquiry.

With such a diverse client mix, we prefer to work on individual schedules with clients, rather than set service contracts. “That way, our clients are only paying for the services they need, rather than a set annual fee.” The company’s highly qualified team can respond to emergencies such as gas leaks immediately, while we aim to attend to plant and equipment breakdowns within the hour. “We also provide a 24-hour emergency response service for our commercial, industrial, and energy supply companies.

A growing part of Gas Engineering Services business is the fitting of new “condensing” boiler systems and instantaneous water heaters that are returning efficiencies of up to 98%. This compares to 85% being achieved by most standard boilers. There are condensing boilers to fit the smallest domestic dwellings, through to the largest commercial or industrial operations, while condensing systems can also be retrofitted to many existing boiler systems.

The importance of correct maintenance on all gas-burning equipment should be regarded as a clever strategic move by business owners and managers. It will surely lead to fewer interruptions and an overall reduction in operating costs.
