EKO Line boilers provide a convenient, safe and environmentally friendly way to heat your home and domestic hot water with wood. EKO boilers assure the independence and self-reliance that heating with wood provides. Because the Eko-Line boilers use wood gasification combustion, they give unusually high overall heating efficiency. They use substantially less wood than conventional boilers and outdoor water stoves with no visible smoke when fully operating.

EKO-Line boilers
are equipped with RK 2001 UA enabling:
Interaction with circulating pump,interaction with room temperature
sensor, installed in the room and connected with the boiler regulator
by two-strand wire, modulation of fan rotation, boiler output adapting to actual weather conditions, 9nteraction with
EUROSTER room thermostat. Each boiler is able to work without room temperature
sensor as well.
Basing information about boiler assembly
1. Boiler placement. Boiler can be placed in the heating room, basement,
or in an outside wood storage building. There should be enough space
to accommodate fuel storage for the whole heating season.
2. Boiler start-up rules. Each boiler should be connected to the heating
system of which the heating capacity equals that of the boiler output.
To protect the boiler against low-temperature corrosion the end-user
should assure return temperature does not reach lower than 120F. It
is possible by installing a four way mixing valve.
Boiler has to
be connected to the chimney duct in the smallest distance possible.
Chimney duct should be insulated to prevent condensation (low exhaust
temperature). The chimney should have the section and height assuring
required chimney draught (see table).
Options8" Draft Booster
This optional unit will
increase your draft if your chimney is not producing enough draft.
Danfoss Thermostatic Mixing
Valve is a boiler by-pass valve that prevents cool return water temperatures
in a hydronic heating system. The purpose is to safeguard conventional
non-condensing boilers against corrosion from condensation that would
result if a minimum flue gas temperature is not maintained.

Features
Gasification Nozzle - made of refractory concrete, mixes wood gases with the secondary air and a flammable mixture is produced that undergoes self-ignition at about 1000°F.
Sealed Wood Gasification Chamber - used simultaneously as a loading chamber. When appropriate amount of primary air supplied by the pressure fan is delivered, wood gas is generated.
Exhaust Reheat Space - the main combustion chamber, where temperature reaches about 2000°F serves as an ash pit. Very little ash remains, reducing maintenance.
Smoke Tube Heat Exchanger - (flue gas to water) heats up the water for heat transfer, cools the exhaust temperature virtually eliminating chimney fires!
Combustion Fan - linked to the microchip controller, monitoring the quality of the whole burning process, increasing burn efficiency.
Safe Guard Thermostat - each boiler is equipped with an additional safe guard thermostat, which switches off the fan while the water gets up to 180°F.
Boiler Body - boiler casing is made of welded boiler plate steel sheets that are 6mm thick, whereas the remaining walls are 4mm thick.
Heat Exchanger- smoke tube heat exchanger made of tube with dimensions 57 x 4mm.
Insulation - boiler thermal insulation is composed of glass wool of Nobasil 20mm thick, while the external casing consists of metal sheet panels 0.8mm thick (powder painted).
Nozzle- ceramic element made of refractory concrete (working temp. up to 2100° F).
Chimney Flap - made of high quality steel. Tight flap adhesion to the combustion duct assures the burning chamber tightness.
Boiler Regulator - placed on upper boiler cover. The regulator is fixed to the boiler cover by stuck catch.
Chimney Flue - made of 4mm steel tube.
Ash Pit- steel bottom of the burning chamber, ceramic ash pit added (working temp. 2100° F) and additionally covered by refractory concrete.
Boiler Door - produced of high quality steel, insulated with Nobasil thermal insulation and inside covered by refractory concrete layer.
Also protected with heat-resisting fiberglass cord.
