Advantages of black coal boilers
Modern Approach
Today’s technology goes hand in hand with quality.
Small boiler size
The H8 boiler product line are small in size and highly efficient.
Czech tradition
Since starting boiler production in 1959, we have gained generations of experience.
Cost Saving
The solid fuel boiler’s high efficiency saves heating costs.
You seek to combine the most modern methods and conventional fuel.
H8-C black coal boilers will not burn your time, the environment and their operation es easy on your wallet. When you add modern accessories, you can further increase the comfort of heating.
Easy Operation
- It can also be set to self-regulation based on the outdoor temperature, so it balances the temperature differences.
- The container lasts up to 3 days in winter without the need to refill fuel.
- You can add GSM and an Internet module for control via a mobile phone or PC.
Economic operation
- Efficiency up to 92.8 %.
- Low fuel and electricity consumption.
- Belongs to emission class 4 and 5 and meets ecodesign conditions.
Small size
