Termo Extra is 100% energy efficient electric boiler for central heating available with wide power range (6 kW up to 96 kW). Termo Extra boiler is suitable as reserve or parallel source of heating in central heating system, but it can be used as independent heating source also. Termo Extra boilers are not equipped with pump nor expansion vessel.

Termo Extra boiler can be connected in cascade system. Boilers are equipped with automatic deaeration system and low voltage system. In case of industrial usage for powers larger than 36 kW, it is possible to connect the boiler to central controlling and managing system (when ordered control system’s characteristics must be specified). Boilers have only upper pipe connections, silent operation and modern design this boiler is very easy to blend into living space.
Electric boilers Termo Extra do not need chimney connection and additional maintenances are not necessary and that is a reason for choosing this kind of heating in front of other heat sources in central heating systems (gas, heating oil, solid fuels).
Boiler can be used in open and closed central heating systems, for underfloor and radiator heating. Usage of electric boiler can be even easier when room thermostat (230V) is connected to it. 

Options, as electronic control panel with outdoor temperature compensation, control panel with possibility of heating domestic hot water or cascade power limiter enables even more benefits and savings.Boilers are delivered in white color; they can be delivered in other colors according to special order.

Warranty period for boilers is 36 months.

Options

Option	Description	Picture
E	Digital control panel enables user more precise control over temperature inside boiler and step by step activation of heaters. For additional comfort room thermostat can be connected.
C	Digital control panel with external temperature compensation enables optimal use of boiler by lowering energy cost and «set and forget» type of functioning. Outside temperature is monitored over provided temperature sensor. Regarding to outside temperature and selected correction curve software in control panel will decide how much temperature is needed. User can offset selected curve or even limit maximal power of boiler. For additional comfort room thermostat can be connected.
W	Digital control panel with external temperature compensation and domestic water gives user all above mentioned plus precise control over temperature in domestic water cylinder. For this to be functional water cylinder must have heat exchanger. Water cylinder in not delivered with boiler it must be purchased separately.
