THERMOWATT RTM-300 Thermostatic Resistance Heater 2000W 1 1/4″
Precise, energy-efficient water heating for tanks, boilers and solar systems.
The THERMOWATT RTM-300 Thermostatic Resistance Heater brings precise temperature control to domestic and industrial water heating systems. In addition, its integrated RTM-300 plug-in thermostat works in full harmony with temperature control systems. Therefore, this copper heater delivers reliable hot water service across a wide range of installations.
A 2000W (2 kW) rating at 220V drives efficient heating, while the 28 cm (280 mm) straight copper body transfers heat quickly to the liquid. Moreover, the brass threaded head resists corrosion and seal deformation. The 8.5 mm tube accepts 8 mm to 8.5 mm sensor pockets, and the unipolar thermostat switches at 20 A / 250 V with 8 °C ± 4 °C hysteresis. Maximum ambient temperature is 105 °C, and the electrical connection uses 6.3 mm x 1.0 mm quick faston terminals.
