Electric boiler Ardesto EHB-15PS

Simple and convenient control

The boiler is equipped with a hydraulic group based on a circulation pump with a pipe for filling in the coolant, an air release valve, a sensor for limiting the maximum pressure to 0.3 MPa, a pressure gauge, and a built-in 7-liter expansion tank.

The boiler supports a three-way valve to connect the circuit of the hot water supply system. The boiler has a high level of protection against emergency situations: protection against breakage or absence of grounding, protection against the excess temperature of the coolant, protection against "freezing" and protection from "sticking" pump (summer mode). Graphic liquid crystal display is equipped with an optimal number of control buttons and a structured menu. It has 16 display positions, each of which corresponds to its function. The LED-display of the boiler provides information about the current state of the boiler and the values of the set parameters, which significantly simplifies the setting and controlling the boiler.

Modes for comfort and safety

Summer mode (protection against sticking of the pump). Helps to avoid the deposition of salts (scale) in the system by turning on the pump once a day for 5 minutes.

Winter mode. This mode allows adjusting the operation of the boiler i.e. the heating system, HWS and the "warm floor" system.

Weekly and daily programming mode (48 time intervals, 8 programs for 7 days of the week). It makes it possible to program the operation of the boiler for each day of the week with an interval of 30 minutes.

Weather-compensated control mode according to equipotential curves. The boiler automatically adjusts the mode in accordance with the changing temperature of the ambient air; for this, an outside external temperature sensor must be connected. Locking buttons against false pressing (child protection). Eliminates accidental pressing of buttons on the control panel.

Frost protection mode. This function ensures the operation of the boiler and the pump to maintain at least 7 °C temperature of the heating agent, which allows you to easily restore the operation of the boiler to full capacity, after a long period of non-use during the heating period.

Boiler protection systems

• Protection against breakage or lack of grounding. Increases the electrical and fire safety of the boiler.
• Protection against an emergency increase of the coolant temperature, above + 95 °C. Provides protection against boiling of the coolant, in turn, guarantees protection against failure of the heating system.
• Protection against coolant pressure decrease in the system. Allows you to protect the heating element from fire and boiler failure.
• Protection against pressure increase above the maximum 0.3 MPa. Protects the system from breakthrough and failure of the coolant.
