Winnerwell® Wood Burn Stainless Steel L-sized Hot Tub and Pool Water Heater          Patented Design

● 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.

As a rough guide, we recommend using the Winnerwell Wood Burn Stainless Steel L-sized Hot Tub and Pool Water Heater for pools with a volume of up to 10m³, and Winnerwell Wood Burn Stainless Steel XL-sized Hot Tub and Pool Water Heater for pools up to 20m³.

The water circulation between the heater and the pool can be done by gravity; in this case, the connection pipes must not be longer than 50cm.

If the distance is longer than 50cm, it's recommended to use a pump. But the flow rate of the pump should not exceed 2000 liters/h, or it should be able to be regulated with a valve or ball valve. A pump with a low operating pressure (<1 bar) is recommended to minimize the risk of pressure increase in the heater.

The water circulation between the heater and the hot tub or pool can be done by gravity, in the case that the connecting hoses/pipes must not be longer than 50cm.

If the distance is greater than 50cm, it is recommended to switch a pomp between, but this should not exceed a flow rate of 2000 liter/h, or can be regulated by means of a valve/ball valve. A pump with a low operating pressure (＜1 bar) is also recommended to minimize the risk of an increase pressure in the heater.
