Advantages
Modern technology
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.
The automatic coal boiler is exactly for those, who seek a combination of the most modern methods and conventional fuel.
Easy Operation
- The container lasts up to 3 days in winter without the need to refill fuel
- It can also be set to self-regulation based on the outdoor temperature, so it balances the temperature differences
- 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
- It's also suitable for small boiler rooms with low ceilings
- Boilers with an output of 15 kW and 24 kW can also fit through a 60 cm width
- The burner can be placed from the right or left side
Automatic boilers long service life
- Cast iron retort burner
- Warranty 5 years
- Double protection against fuel burnout and automatic boiler overheating
