Built to pair with an Econergy heat pump
These stainless steel cylinders are made to connect to an Econergy HP4000LT or THD3500 heat pump water heater with insulated pipes and cables. Temperature sensors are built in at the top and bottom, and each cylinder has a 3 kW element, so the heat pump’s controller can switch to the element when needed.
Sizes
EC180L, EC250L and EC300L (180, 250 and 300 litres). Econergy makes larger custom cylinders on request.
Indoor or outdoor
The outside of the cylinder is weatherproofed, so it can go indoors or outdoors. Econergy recommends indoors where possible, to reduce heat loss and keep it close to where you use hot water.
Warranty and standards
A 10-year manufacturer’s warranty. The cylinders meet or exceed New Zealand’s Minimum Energy Performance Standards (MEPS) under AS/NZS 4692.
Look after your water
Like any cylinder, these last longer on balanced, filtered water: see how your water affects your hot water cylinder.
