Wood Fired Burning Log Burner Hot Tub Spa Swimming Pool Stove External Heater

Our hot tub water heater has been engineered for maximum efficiency, utilizing a sophisticated heat exchange design. The stainless steel body surrounding the firebox is a double-wall water-jacket, making the entire firebox a heat-to-water transferring surface. The stove is made from 2mm thick AISI304 Stainless Steel which has excellent corrosion resistance and can withstand exposure to chlorine and saltwater.

This wood burner is a precision-built, high-efficiency water heating stove designed specifically for hot tubs and swimming pools. It eliminates the need for a circulating pump and electricity, making it possible to heat the water in a hot tub with the heater placed externally. A big advantage is that there will be more space in the tub, which in turn means a smaller model can be selected. 

It circulates water using the principle of “thermosiphon”. Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates the water without the necessity of a mechanical pump. Hot water rises and creates low pressure, which draws the water from the bottom inlet. 

The stove will work/exchange the water without circulating pump (with natural convection) but only if it's placed on the same level/height as the hot tub and within the maximum distance of 50 - 60cm.

Circulating pump would need to be connected if, for any reason, you need to place the stove on a different level (e.g. hot tub is situated on the decking or any other raised construction but the stove is placed lower on the grass) or if there is no free space for the stove around the hot tub and the stove needs to be placed far away from the hot tub.

For use with swimming pool rather than a hot tub a low-speed electric pump is always suggested or even required to assure a smooth flow of water.

Hot water central heating circulating pump or swimming pool filter pump with a flow rate of 1500 - 2500 L/h would be ideal and recommended. 

Please note that if the pump is installed it must be switched off and disconnected from the mains electricity before entering the pool / hot tub. 

The chimney is 215 cm high and comes in two parts, the bottom pipe with the heat shield and the top pipe with flue cowl / cap.
