Multi Energy Water Cylinder

Large or remote homes can benefit from more water heating flexibility. A multi energy source hot water cylinder can draw heat from heat pumps, boilers, solar water heaters, and wetback fires.

The Heart of a Stately Home

Multi energy source hot water cylinders are becoming more common in large new homes and off-grid homes alike. Put most simply, they treat a large hot water cylinder like a battery or storage device for heat. They solve the problem of integrating many different energy systems for heating your home’s hot water, pool water heating, hydronic underfloor heating and radiator heating.

With multiple connections and heat exchanger coils inside the hot water cylinder, it transfers heat from a range of sources to a range of outputs. Solar hot water heating arrays, gas boilers, solid fuel or wood boilers, large wetback fireplaces, hot water bore heat exchangers and hot water heat pumps (HPHW) are among the many possible inputs to these systems.

Large home versions often have capacities of 500 litres, and in some cases 1000 litres. Smaller versions are available for linking wetback fireplace water heating systems with solar water heating systems.

We wish to acknowledge the awesome service provided right before Christmas Eve. Very grateful for your willingness to accept the job and get it done – which meant our son and family could enjoy a well-deserved holiday with running water!!! Please pass on our appreciation to the staff as well. We will be recommending your business.

We have had Dale to our place three times - underfloor heating problems, gas hot water issues and a stove service. Each time he arrived at said time and explained everything as he fixed the issues. Great communication and would highly recommend. Thanks.

I booked Eco Plumber to relace a shower rose. Due to a change with one of their appointments. They came the same day I booked them. Brilliant service. Prompt. Took all the discarded bits with them. Very fair charge. I will use their service again.
