Wetback Log Fire

A wetback fire provides considerable utility and energy savings in the cooler months. They’re a perfect complement to solar water heating systems and are essential for any off-grid home.

Reliable, Carbon-Neutral Water Heating

Many of us have access to firewood – trees grow relentlessly on lifestyle blocks in the sunny Tauranga area and across the Bay of Plenty. Modern, high-efficiency wood fires are carbon-neutral when the firewood comes from locally-grown trees.

Modern fireplace technology has reached record-low emissions for wood burning, and fireplaces with wetbacks have the same low emission profiles while efficiently delivering heat to your hot water system. A well-matched wetback is able to heat your hot water cylinder in about an hour.

The Perfect Complement to Solar

Considering solar hot water systems operate the least efficient in the winter, and wetback fires are mostly used in the cooler months, the two systems are made for each other.

Still, things aren’t that simple. The size of the hot water cylinder needs to be chosen carefully to suit the size of wetback installed in the fire. A tiny 2kW booster in your fireplace can’t properly heat a large 300-litre hot water cylinder – it’s just not powerful enough.

However, that same 2kW wetback would be adequate for a smaller 130 to 150-litre hot water cylinder. For a high-performance system, the hot water cylinder also needs to be located as close as possible to the fire, with the shortest pipework run possible.

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.
