THERM EL 14

Due to the low minimum output and modulation option, the THERM EL 14 boiler is recommended for heating modern buildings and low-energy passive houses. The boiler’s compact dimensions rank it among small boilers. The water can be heated in an external reservoir after the boiler is fitted with a three-way valve. The boilers are supplied with an elegant stainless design.

The boiler must be installed and connected by a professional company. During installation, it must be remembered that the electric boiler must be allocated additional power - i.e. suitable securing must be ensured in the switchboard or the building to prevent disconnection of the main circuit breaker during operation. The maximum current is monitored for this purpose, which can be installed into the switchboard to monitor the amount of current required for a particular time and in the case of exceeding a certain limit, part of the electric boiler output is disconnected. The electric boiler also operates with a rate switch, which runs the boiler in the reduced rate.
