We require the correct flow rate to the various gas appliances, so we calculate the correct pressures required and the correct pipe sizing through property to ensure all installed gas equipment or appliances can operate at the same time. Sounds easy but it is a skill often overlooked.
The single largest gas installation we have undertaken was earlier this year with 3490mj/hr being sent into a commercial laundromat at 7kpa pressure. This equates to 966kw/hr. As a comparison your hot water cylinder will Use 3k/hr and your whole home may peak at 12 or 15kw/hr if you have all the heatpumps going. As a result gasfitters on the whole are a cautious bunch and go around spouting regulation and test themselves constantly with regulations always at forefront of mind.
Commercial gas fitting often requires us to work with specialised equipment that is new to the industry. New appliances are being created all the time. We had a recent opportunity to install commercial pasta cookers that require double-check valves for backflow compliance and copper waste to drain, working with mobile food trailers installing full gas supply with deep fryers and grillers and LPG bottles mounted securely at the front of the trailer.
Another challenging recent project was to convert an entire motel over to natural gas supply, run large diameter polyethylene pipework around the motel with gas pressure at 70kpa pressure servicing 14 Rinnai Infinities and a pool heater. This involved shutting down Cameron Road at one point and thrusting a gas main under t
