The Winnerwell Wood-Burning Hot Tub and Pool Water Heater is a high-efficiency, off-grid water heating solution designed specifically for outdoor hot tubs and pools. It utilizes the natural thermo-siphon principle to circulate water without the need for electricity or a pump. The heater is placed externally, which not only frees up space inside the tub but also enhances heating efficiency. Crafted entirely from durable stainless steel with a double-wall water-jacket structure, it transforms the entire firebox into a powerful heat exchanger for consistent and effective water heating.

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 litres 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.
