KF boilers from the manufacturer. Water heating, Poltava region.

KF boilers are intended for heating individual residential buildings and utility buildings, equipped with a water heating system with natural or forced circulation. KF boilers are designed for operation on solid fuel DSTU 3472 (anthracite, stone and browncoal) and firewood according to GOST 3243-88.
The thermal power of the boiler depends on the calorific value of the fuel!
The technical characteristics given in the table below show the highest thermal capacities of the boilers, which are possible when using only anthracite.

It is possible to manufacture cauldrons according to the Customer's individual dimensions.
Boilers that work on briquettes,coal, firewood can be equipped with a draft regulator. The boiler consists of two placed one above the other, the upper chamber is intended for the combustion of gases, in the lower chamber fuel is burned. Heating chambers are made of steel with a thickness of at least 3 mm, it is possible to order a heating chamber from steel with a thickness of 4 mm. The original design of the firebox without grates (the bottom of the firebox is a water jacket and is also cooled by water). This design dramatically increases efficiency and reduces fuel consumption, unlike other boilers. The dimensions of the loading door are 350/350 mm, which allows you to burn large pieces of wood. Heated premises up to 250 sq.m. Each solid fuel boiler undergoes the following tests: test of the boiler furnace for the absence of leakage; testing of the boiler body for the absence of leakage at high pressure; testing of the water heating circuit at high pressure These boilers are characterized by high reliability, high efficiency, simple installation, operation and maintenance, these boilers can be used in conjunction with a gas boiler. PAYMENT WITH VAT IS POSSIBLE for legal entities.
The service life is said to be 10-15 years.

It is possible to manufacture cauldrons according to the Customer's individual dimensions.
It is possible to additionally equip cauldrons with electric heaters 220-380V, power from 2.5 to 7 W.
