This water heater is a precision-built, high-efficiency water heater designed specifically for hot tubs. It circulates water using the principle “thermosiphon”-hot water rises and creates low pressure, which sucks water from below.


●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.

●Every detail of the Winnerwell® hot tub water heater has been engineered for maximum efficiency, utilizing a sophisticated heat exchange design.The stainless steel body surrounding the firebox is actually a double-wall water-jacket, making the entire firebox a heat-transferring surface.

For pools up to 10m³, opt for the Winnerwell Wood Burn Stainless Steel L-sized Heater. If the pool is up to 20m³, the XL-sized Heater is recommended. When the distance between the heater and the pool is less than 50cm, gravity can handle water circulation. However, if it exceeds 50cm, a pump is advised. The pump should not exceed a flow rate of 2000 liters per hour and should have a low operating pressure (<1 bar). It’s crucial to regulate the pump with a valve or ball valve to prevent pressure spikes in the heater. The same guidelines apply to hot tubs.
