## Long description

The BT-S 50 water heater is a compact, wall-mounted electric boiler designed to provide reliable hot water for small households, kitchens, showers or hotel rooms. With a 50-litre enamelled steel tank and anti-corrosion protection, the unit supplies stable water temperature and continuous operation while reducing energy consumption through effective thermal insulation.
Advantages
The BT-S 50 features a two-layer titanium enamel coating on the tank interior, a magnesium anode to limit corrosion and scale, and a 2 mm insulating gap between the tank and the steel casing to lower heat losses. An ANTI-MIX system prevents cold and hot water mixing and sudden temperature swings. The heater uses a high-quality Italian copper heating element rated 1200 W that ensures consistent performance even with voltage drops and includes corrosion-resistant properties and overheat protection. The adjustable Italian thermostat provides automatic operation, temperature control and safety.
