The barrel heater is a heater designed to keep water melted and heated. The easy-to-use heater can be immersed directly in water and placed on the edge of the container. The surface temperature of the heater is low, so the risk of burning is almost non-existent. The heater resistance pipe is made of stainless and heat-resistant material. At least 40 cm from the resistance tube must be submerged in the liquid. The heater has an adjustable thermostat 30 ° -90 ° C and 0.6 m connecting cable and a plug.
