UKY/Y Series Boilers
Product Code: ÜKY/Y

Ünmak ÜKY/Y series automatic solid fuel boilers are designed to burn coal, prina, pellet and nutshells with diameters up to 25mm. The boilers have different capacities with high efficiency. The boilers are user friendly and provide comfortable heating.

ÜNMAK ÜKY/Y series automatic fuel feeding heating boilers are designed to burn coals between 10 - 25 mm in the market, known as brass coal, hazelnut coal, in the crucible. It is produced in various capacities with its high efficiency. Thanks to its superior features; It provides comfortable heating and is very easy to use.

Produced with superior technology, ÜNMAK automatic fuel feeding boilers have a longer lifespan than their counterparts with their production in accordance with EN 303-5 standard. Special flame tubes reach the desired temperature in a short time and switch to the regime with the 3-pass combustion system that increases efficiency. With this feature, fuel consumption is minimized.

Thanks to the modernly designed electronic control panel, all functions of the boiler can be easily controlled. The fuel is sent to the combustion pot in sufficient quantity within the set time and burns extremely efficiently. The temperature can be adjusted according to the desired temperature.

The high-capacity fuel tank does not require fuel feeding for a long time, and thanks to the round pot, the ash is automatically poured into the ash bucket, so it does not require long-term labor.

Ideal combustion: By feeding the fuel from the bottom, a continuous and good combustion is achieved on the combustion pot and fuel consumption is minimized. With this feature, clean and smokeless combustion is achieved. Waste polluting the environment has been minimized.

Combustion delay: The boiler can be turned off from the control panel if the outside temperature is high, regardless of the temperature. In this case, when the fan and flap are closed, the burning fuel will darken and combustion will be delayed. When the need for heat arises again, the boiler will be turned on from the control panel and will continue to burn without the need for ignition and will reach the desired temperature in a short time. (combustion delay can be done up to 24 hours depending on coal quality)

It is easy to use; It is sufficient to ignite it once at the beginning of the season. Thanks to the round burning crucible, the ash pours into the ash bucket automatically. The ash bucket can even be emptied weekly. This feature requires less labor than its counterparts.

Thanks to the Automatic Stop Feature, the fan and circulation pump automatically stop when the fuel runs out. This feature provides energy savings.

Economical: It is possible to heat economically due to the ability to burn cheap fuels.

It is possible to obtain hot water by adding a hot water storage tank.

Assembly: Boiler and stoker can be shipped separately if desired. Thus, it can be easily placed in boiler rooms with narrow entrances.

Warranty: ÜNMAK automatic loading floor heaters are guaranteed for 2 years against production defects.
