TimberIN advice & guides

An external wood-burning stove can heat a hot tub simply and efficiently, provided water can circulate correctly between the tub and stove. In a natural-circulation installation, there is no pump to force the movement: the temperature difference and gravity do the work. Stove position, connection direction and pipe gradients are therefore essential.

Check whether each part of a wood-fired hot tub needs power: heating, circulation, filtration, jets, lights and controls, including power-loss behaviour.

Recognise electrical hot-tub warning signs, stop use safely and preserve useful fault details for an electrician. Avoid repeated resets and DIY repairs.

Build a hot-tub cost-per-use estimate from measured fuel, electricity, water and care costs. Includes an illustrative calculation with clear assumptions.

Check water level, circulation, fuel, flue clearances and supervision before heating a wood-fired hot tub, with clear stop-use signs.

Roof runoff needs more than a leaf filter. Check catchment risks, source testing and treatment compatibility before filling a hot tub.

Tell deposited rust marks from possible metal damage. Record the location, water readings and cleaning history before choosing a compatible remedy.
