What are Hot Water Cylinders?

Your reliable source for instant hot water. A hot water cylinder is an essential part of most homes’ plumbing and heating systems. It is an insulated tank designed to efficiently store a volume of hot water heated by an external source—like a boiler, solar panels, or a heat pump—ensuring it is ready for immediate use across all your taps and showers. 

These systems are typically categorised as either vented (connected to a cold water tank in the loft) or unvented (connected directly to the main water supply for higher pressure). At Polar Energi NZ, we help determine the perfect type and size for your home’s unique demands, ensuring efficient storage and quick access to hot water when you need it most.
