Northwood is one of Christchurch's newest suburbs, developed from 2000 as a subdivision of Belfast on land that was previously apple orchards. The wider Belfast area saw only minor liquefaction and little damage in the Canterbury earthquakes. If your cylinder has failed, we can usually have hot water back on in Northwood within a day. If it is still working but showing its age, we can plan the swap at a time that suits you.
Northwood's first-generation cylinders are coming due
Northwood was developed from 2000 on former apple orchards, so most homes still have the cylinder they were built with or have only recently replaced it. At over twenty years old, many of those first units are past the 10 to 15 year guide from Consumer NZ, and the usual warning signs are rusty water, a leak from the tank shell and a relief valve that drips constantly. Because the houses went up over a similar period, when one cylinder on a street fails, the neighbours' units may not be far behind.
Most Northwood homes are on mains pressure already, which makes a replacement simpler than in older suburbs. The work is usually draining and removing the old unit, fitting a new cylinder with fresh valves, including a tempering valve to keep bathroom water within Building Code limits, and restraining it to G12/AS1. If the original strapping is loose or incomplete, we bring it up to standard. Homes near Styx Mill Conservation Reserve and The Groynes are on open plains where frost settles on still nights, so garage pipe runs are lagged.
Because the houses are of similar age, a replacement is a chance to rethink the type rather than repeat the original. A heat pump water heater or an LPG system can suit, and we compare them with you, including how a controlled hot water tariff on the Orion network affects the size you need.
Local tip: Northwood owners can read the manufacture date on the cylinder label to see whether it is still the original unit.

Canterbury frosts can freeze and split exposed relief drains and pipework near the cylinder. We lag what is exposed and check the valves after a hard winter.

Hot Water Cylinders Northwood FAQs
Should we replace our original Northwood cylinder before it fails?
If it is leaking, discolouring the water or not keeping up, planning the swap avoids an emergency. If it is working well, a valve check may be enough for now.
How long does a cylinder replacement take?
Most straightforward replacements take a few hours. Upgrading from low pressure to mains pressure can take longer.
Can you replace an LPG water heater?
Yes. We install and replace LPG continuous flow and storage water heaters, including the gas connection and certification.
