Rolleston is one of New Zealand's fastest-growing towns, rising from about 2,800 people in 2001 to about 28,000 in 2023, so much of the town has been built in the last two decades. Growth sped up after the Canterbury earthquakes because of the town's stable ground and Selwyn District Council's fast tracking of building consents. In late 2020 the council was considering private plan changes to rezone land for a further 4,500 houses. Most homes in Rolleston run on an electric cylinder in a cupboard, the garage or the roof space. We remove the old unit, fit the new one with fresh valves and connections, and test it before we leave.
Rolleston's fast growth and the first wave of cylinder swaps
Rolleston grew from about 2,800 people in 2001 to about 28,000 in 2023, so most homes here were built in the last two decades. Their original mains pressure cylinders, commonly in garages or above them, are now the age where replacements begin. We match the new unit to the existing connections where possible and size it for the current household, which may have grown since the house was built. The Izone business park adds commercial work too, where staff facilities need a cylinder sized for shift patterns rather than a family. With Selwyn the fastest-growing district between 2018 and 2023, newer streets keep appearing, and those homes will reach the same point in turn.
The town is on the Orion network. Where the house is on a controlled hot water tariff, the element can be turned off during peak demand on the coldest mornings and evenings, so we choose a capacity that covers the morning rush through those periods. The stony ground meant no liquefaction in 2010, but the town sits close to the end of the Greendale Fault, so restraint to G12/AS1 still matters on every install.
Selwyn District Council handles building consents and water supply here, rather than the city council, and has chlorinated Rolleston's water since October 2022. Frosts are common across Canterbury in the cooler months, so garage pipe runs are lagged and relief drains are routed to run clear.
Local tip: Check whether your Rolleston power bill shows a controlled hot water rate, because it changes the cylinder size we recommend.

Hot Water Cylinders Rolleston FAQs
Our Rolleston cylinder is in the garage. Should we move it inside when we replace it?
Usually it can stay, with better pipe insulation. Moving it is possible but adds cost, so we explain both options before you decide.
What are the signs my cylinder needs replacing?
Leaks from the base, rusty water, long reheat times and noises from the tank all suggest it is near the end.
Should I get mains pressure or low pressure?
Mains pressure gives better showers and flow, but your pipework must handle the pressure. We check this before recommending it.
