Electric Water Heaters (Hot Water Cylinders)

Mains Pressure Electric Water Heaters

Designed and manufactured to meet New Zealand's energy performance standards, Rheem mains pressure electric water heaters (hot water cylinders) are top performers under a wide range of water pressures and conditions. Models are rated at a maximum of 1000 kPA water pressures respectively (depending on the model). They not only operate on mains pressure but are also suitable for unequal or equal low pressure uses. The electric storage water heater (hot water cylinder) can deliver more than 40 litres of hot water a minute, enough to meet the needs of most households. Due to their insulation qualities, the optimum water temperature is maintained longer, saving energy and ultimately saving on your water heating account.
