Product detailed description

Electric boiler with output modulation Thermona THERM EL 14

The THERM - EL electric boiler is designed by its construction for hot-water heating systems with forced water circulation. It can be installed in central and single-storey heating systems with forced circulation, in open or closed systems. It is an ecologically clean operation with no flue-gas discharge requirements. Unattended operation is enabled by an external controller or yesther external control/operating element (not included in the boiler's scope of delivery); alternatively, a simple weather-compensation controller or a room temperature controller built directly into the control automatics, maintaining a preset temperature in the selected room, can be used. The electric boiler can be used as a universal heat source for heating in apartments, small family houses and recreational buildings, as well as an alternative source when yesther main heating and hot-water source is used (even for a transitional period) - for heat pumps, accumulation systems, or in previously installed single-storey and central systems, etc. For higher outputs, the boilers can be linked into cascades.

Main advantages of THERM EL electric boilers:

extremely fine smooth control in 9 output steps
Therm EL 5 • min. output 500 W, rated output 4.5 kW, control step 0.5 kW
Therm EL 9 • min. output 1000 W, rated output 9 kW, control step 1 kW
Therm EL 14 • min. output 1500 W, rated output 13.5 kW, control step 1.5 kW
suitable especially as a supplementary stable source for heating and hot-water preparation (hereinafter DHW) in combination with solar panels, a heat pump, etc., in passive houses or other buildings with lower heat loss
built-in weather-compensation control
smaller internal-tank dimensions - higher flexibility
smaller external dimensions of the whole boiler - high installation-location variability
smaller water volume, and therefore clearly:
faster temperature rise
more flexible and more precise control
option to use a new control method
new, clearer display method - texts, errors, fault messages...
option to optionally connect the boiler to a single-phase or three-phase supply by simply linking the terminals!
intuitive and easier control via a touch display, better menu orientation thanks to replacing abbreviations with full text)
option of language versions - (Czech, Slovak, Russian, English, German)
option to control the boiler via SMS messages and receive status information - optional (additional accessory available only for a standalone boiler)
integrated topping-up (via a hydro-block), integrated bypass
option to connect all boilers (regardless of type) into an intelligent cascade
design finish in stainless-steel sheet
integrated OPENTHERM communication - option to connect intelligent room controllers or, for example, a higher-level Siemens RVS control system...
option to connect a room thermostat, etc.
