TECHNOTHERM electric storage heater 14 Duo 8+

Series Electric storage heater TTB-E 14 Duo 8+

Room storage heater with static heat output and efficient heat distribution.

Technology and housing made in Germany—for reliable warmth without complex installation.

High-quality technology – developed and manufactured in-house by TECHNOTHERM in Germany.

Safe and EU-compliant: Our systems meet all European safety and environmental requirements.

Long-lasting feel-good warmth

The fireclay storage core absorbs a lot of heat and releases it evenly over many hours. This keeps the room pleasantly warm, even when electricity rates are high.

Low heating costs thanks to favorable tariffs and PV

The room storage heater charges in defined time windows at low electricity prices and automatically adjusts the charging time to the heat demand. Ideal in combination with dynamic tariffs and your own photovoltaic system.

Comfort through smart control

The electronic, internet-enabled thermostat with weekly programs and app connectivity regulates heating output precisely. Features such as adaptive control, charge indicator, and open-window detection increase comfort and save energy.
