Advantages
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.
Easy Operation
- Easy control of the automatic boiler control unit.
- 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 94.2 %.
- Low fuel and electricity consumption of automatic boilers.
- The boiler belongs to emission class 4 or 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 door width.
- The burner with cast iron retort can be placed from the right or left side.
Automatic boiler long service life
- Cast iron retort burner
- Warranty 5 years
- Double protection against fuel burnout and automatic boiler overheating.
