2.3 OPERATION PRINCIPLE OF THE DEVICE
MAKTEK Omega LCD electric combi boiler provides central heating with the use of panel
radiators or underfloor heating pipes. The primary heating circuit water is heated in the
main heat exchanger with the heating elements. The hot water circulates the installation
with the help of the circulation pump, delivering hot water to the radiators or underfloor
heating pipes.
The boiler also produces domestic hot water to be used in sinks and showers in the house.
The DHW is generated by the plate heat exchanger located inside the boiler.
Electric combi boiler senses the DHW demand when the water tap is opened and the 3-way
valve actuator motor changes postion to divert the hot water to the plate heat exchanger
automatically in order to produce DHW. In winter mode operation, DHW supply is always
prioritized.
The above mentioned combi model (heating + domestic hot water) is the standart
production. Besides this model, Maktek Omega LCD boiler is manufactured in different
configurations depending on capacity and customer requirements.
Boilers manufactured for only heating (in standart 50-100kW models) do not provide
domestic hot water (DHW), only operates to heat up the closed heating circuit for space
heating.
External hot water boiler model is available for all capacityies (6-100kW) This is
manufactured on demand of the customer. In this model there are two additional outlets to
be connected to the external hot water boiler instead of the built in plate heat exchanger.
DHW temperature NTC sensor is supplied alongside the boiler with a long cable so that the
sensor can be placed on the external hot water boiler for monitoring and modulation of the
DHW temperature.
The external hot water boiler model is demanded by users who require a high rate of DHW
flow for their multiple baths, or for users who want to use the high capacity boilers for CH
and DHW supply at the same time.
Maktek Omega LCD boiler has a built in weekly timer function, optional room thermostat
and ambiant temperature sensor operation features for advanced automation and comfort.
