Gas boilers Termotechnik TT 100 is designed as a three-pass gas-tube boiler.
Most users of independent control systems undeservedly do not trust technology domestic production. Domestic equipment is considered incapable of performing the required tasks and when choosing, all devices where the manufacturer is the Russian Federation are avoided. Termotechnik gas boilers do not pretend to be serious competitors with Czech, German, Italian and other European models, but in operation they show themselves to be quite high level, and their cost is several times lower than the budget.
The main advantages of gas boilers
The main advantage of all national products is considered to be budget cost, easily replaceable spare parts for repairs and readiness to work in difficult conditions, which not every imported gas boiler can withstand. Among the main advantages of cast iron gas boilers are:
- Gradual decrease or increase in power
- Quite simple and intuitive controls
- Preparation process hot water
- Increased security
- Minimum heat loss
- Low level of heat loss
- Simple service
- Unit durability
Principle of operation
Termotechnik gas boilers are standard devices that do not have any unique design parameters. There is a continuous supply of methane to the burner into the working chamber, which burns and releases thermal energy. Next to the burner there is a heat exchanger where the temperature is transferred to the coolant. Then the heat exchanger constantly circulates through the system so that the batteries do not cool down, maintaining a suitable microclimate.
Computerized automation is responsible for the control process and takes readings from control sensors, depending on the received information, which controls further actions. The performance parameters cannot be compared with well-known world-class manufacturers, but for the domestic market they are at a fairly high level. A gas boiler made of cast iron is suitable solution the creation of all existing heating systems of the home, since its use is related to the connection of an already specified cycle. Usually a cast iron gas boiler is connected to the old heating system indoors, due to increased reliability and increased power.
