Safety Features

UKO heaters are designed with essential safety features in mind. The main body of the heater remains cool to the touch, as the inner fire chamber is surrounded by a water heating chamber. This means the outer surface only heats up to the temperature of the water inside.
Additionally, the lower part of the chimney is equipped with a thermal guard for extra protection.

However, users are responsible for following basic fire safety guidelines, such as maintaining a safe distance of at least 2 metres between the chimney and any roof or flammable materials, and avoiding placing flammable items near the heater.

Best Types of Firewood for UKO Heaters

The most suitable firewood for UKO heaters is hardwood—such as oak, ash, birch, maple, or beech. These dense wood types burn slower and hotter, producing more heat with less smoke and residue compared to softwood.
Hardwood is more efficient at maintaining a steady temperature over time, making it ideal for heating UKO heaters.

For optimal combustion efficiency, it is important to use well-seasoned wood with a moisture content below 20%.

Why Choose UKO Heaters?

Fast Heating – Efficient heat exchange system enables quick and effective water heating for your hot tub or water tank.
