Wood-fired · Jacuzzi heaters

Hot water, no power run.

A coil that brings a tub up on wood alone — no pump, no element, no electrical service to the pad.

The line

A wood-fired jacuzzi heater brings a tub up on wood alone. There is no pump, no element and no electrical service to run out to the pad, which is the whole reason people put one on a property where power is a trench and a permit away. Heat moves by convection: cold water leaves the bottom of the tub, passes the fire, and returns hot at the top. We are building the line now. Nothing is orderable yet.

Bought on

Tub capacity

Tub capacity
The litres the heater is sized for. Run it under capacity and heat-up drags; run it over and the water stratifies.
Heat-up time
From cold, at a stated ambient. A figure without an ambient temperature attached is not a figure.
Coil specification
Grade and wall thickness of the submerged or external coil, which is what decides how long it survives treated water.

Coming soon

The jacuzzi line is in development.

We are building it and we are not going to put figures on this page before we have measured them.

Tell us the tub you are heating and the property it sits on, and you will hear from us when the line is ready — with real numbers, not an announcement.
