TECHNICAL FEATURES AND DIMENSIONS
2.1.
Technical features
The ENERDENSE boiler is a high efficiency steel boiler, with horizontal condensing heat
exchanger, function for liquid or gaseous fuel.
The heat exchanger is made of special stainless steel, corrosive resistant, which ensures
optimal heat transfer from flue gas to the water.
It functions on the principle of reversed flame, and then guidance of the flue gases towards the
third pass, positioned at the upper part of the boiler, where they are further cooled until the
condensing temperature. The heat absorbed by the condensation preheats the water entering
the boiler. Flue gas temperature at the exit of the boiler is 55
o
C.
It is appropriate for function with pressurized burner for light oil or natural gas.

Function principle
ENERDENSE is a high efficiency steel boiler with condensing heat exchanger, for function with
liquid or gaseous fuel.
The heat exchanger is made of special inox steel, with high corrosion resistance, which ensures
optimal heat transfer from the exhaust gas to the water.
The function is based on reversed flame in the fire chamber, the exhaust gases are then
guided to the tubes of the third pass positioned at the lower part of the boiler, where they are
further cooled down until they reach condensing temperature. The heat obtained by the
condensing heat exchanger is used to pre-heat the water entering the boiler. The final
temperature of the exhaust gas is 55
℃
.
The unit is designed to function with liquid or gaseous fuel burner.
In a conventional boiler, the water is heated through the heat of combustion, and the resulting
flue gases are guided to the chimney. As a result, the energy contained in the flue gas is lost.
Condensing technology exploits these gases, which consist to a large extent of hot water
vapour. It extracts the flue gas heat and feeds the energy obtained into the heating circuit.
In order to extract this energy, water vapour must condense. It does this at a temperature of
below 55°C. The condensing boiler cools the steam through a specially designed heat
exchanger. The energy gained is used to preheat the cold heating water. The hot water then
passes into the primary heat exchanger where it is heated further to reach the desired
temperature. During this process, small amounts of waste water occur which must be disposed
of at the drainage.
Condensing boilers must be connected to a plastic pipe for the flue gas.
