Demrad Adonis B-24 is a double-circuit wall-mounted boiler, intended for heating and supplying domestic hot water to homes and apartments in buildings with chimneys or special fireplaces for chimneys. It can also work effectively with low temperature systems such as underfloor heating. The covered heating surface can reach up to 240 m².
The principle of operation
The main distinguishing feature of the "Adonis" series boilers is that this boiler takes the air required for combustion directly from the room in which it is installed. Also, waste gases are discharged through a special chimney, which generates the natural traction necessary for gas combustion.
The advantages of these boilers compared to those with a turbocharger consist of simple construction, lower costs and reduced electricity consumption, as well as low noise level during operation. It is important to remember that, due to the constructive features (open combustion chamber), boilers of the "Adonis" series must be installed in well-ventilated rooms. These boilers are ideal when replacing old equipment, which generally had a smoke exhaust system.
The boiler is controlled by a reliable and efficient controller. It is responsible, among other things, for the direct ignition (from the electrode) of the burner and the continuous modulation of the amount of gas supplied to it. This allows for a significant reduction in fuel consumption while maintaining a stable water temperature in the system. Thanks to its improved construction, a high efficiency of heat exchange is obtained, with an efficiency of up to 91%, and the instantaneous heating of water for several points of use (eg kitchen sink and shower). The control panel is equipped with an LCD display, which allows monitoring of temperatures, pressure in the system and displays error codes in case of incorrect operation. By means of a manual function switch, the boiler can be set to operate in one or two modes: domestic hot water only (summer mode) or domestic hot water and central heating (winter mode).
Domestic hot water mode. When hot water is requested, the boiler is switched on automatically. Power is then supplied to the built-in pump and hot water from the boiler's primary circuit is routed through the secondary heat exchanger, allowing the heat of the incoming cold water to be instantly transferred. The secondary heat exchanger is protected against internal scale formation by limiting the maximum hot water temperature to 64 °C. Hot water will continue to flow through the faucet until the demand is met. After there is no more demand for hot water, the built-in pump can continue to run for a short time to disperse the excess heat inside the boiler.
Domestic hot water and central heating mode. When hot water is requested, the boiler is switched on automatically. Then the power is supplied to the built-in pump, and the hot water from the primary circuit of the boiler is directed to the pipes and radiators of the heating system. The heating output of the boiler is automatically adjusted by the built-in control system to suit the heating needs. As the water temperature in the heating system rises, the gas supply to the burner is reduced, saving energy and increasing boiler efficiency. When the heating demand stops (or the temperature set on the room thermostat is reached or the heating period ends), the burner stops and the boiler goes into standby mode until the next heating demand. After the burner is turned off, the built-in pump can continue to operate for a short time to disperse excess heat inside the boiler.
