Steel hot water boilers EKO-CKB (nominal heat output 20 - 50 kW) are engineered for solid fuel, pellets, oil or gas firing. They are members of the EKO-CK boilers' family.

Their special distinction is that the stainless steel water heater is situated inside the boilers' water, which makes this product very interesting, because it guarantees constant temperature of domestic hot water without additional investments.

This product can be easily recognized by its modern design, by the synthesis of modern technologies and the quality of material, as well as through their simple and easy assemblage and control. The wide application of double-checked technical solutions, make these boilers safe and reliable. Simple connecting to the burner and boiler regulation, are evidence of their particular value. Produced in compliance with the European norm EN 303-5.

Characteristics of EKO-CKB boilers:

- Hot water boiler for central heating systems is produced for all kinds of fuel (solid fuel, pellets, oil or gas) and has a nominal heat output 20 - 50 kW.

- Domestic hot water heater is made of a high quality stainless steel, which guarantees its high hygienic standard. Its position inside the boiler water allows the whole domestic water quantity to be hot in a short time.

- The built-in hot water heater does not require the application of an additional circulating pump, which otherwise would be connected outside the boiler.

- Accordingly dimensioned combustion chamber, 3-passes flue gas flow and additionally ribbed surface for better temperature exchange assure the operating of the boiler with high efficiency rate. This makes it very "economical".

- The combustion chamber is made out of high quality 5 mm thick steel sheet.

- Ecologically acceptable, which has been proved by very demanding certificate of the Austrian County Styria (FanlG). - The big door enables firing with big peaces of wood, as well as easy cleaning and maintenance.

- The pump thermostat is included in basic delivery.

- A thermal protection can be implemented through appropriate holes.

- The body of the boiler is delivered separately from the casing with thermal insulation which enables easier transportation and assemblage without unnecessary risks.

- For an easy and simple casing assemblage no screws necessary.

- In basic delivery is also included the thermometer and also the cleaning set and the ashtray.

- For oil/gas firing of the boiler a hole on the lower door is accordingly prepared. Quick and easy assemblage.

- The basic boiler regulation of the burner (oil/gas) can be delivered separately. It can be connected on the upper casing lid of the boiler.

- The boiler is tested and certified according to the European norm EN 303-5 and EN 304 at the Faculty of Engineering in Zagreb production in compliance with ISO 9001/2000 norm.

Additional equipment:
Obligatory (solid fuel firing) - draught regulator, manual 4-way mixing valve if the boiler connected to the closed central heating system - thermal safety valve, safety-air vent group (2,5 bar) and expansion vessel; for sanitary water- safety valve (6 bar), expansion vessel and irreversible valve.
Obligatory (pellet firing) - Cm Pelet-set, if the boiler connected to the closed central heating system - thermal safety valve, safety-air vent group and expansion vessel; safety valve for sanitary water (6 bar), expansion vessel and irreversible valve.
Obligatory (oil/gas firing) - boiler regulation, oil/gas burner and for closed central heating system an safety-air vent group (2,5 bar), expansion vessel and for sanitary water an safety valve (6 bar), expansion vessel and irreversible valve.
