Alarko combi boilers and thermal equilibrium tanks were designed because of the increasing day-to-day production of hot water using renewable energy and because the classical auxiliary devices in the hot water installation do not respond to the needs of these methods.
Renewable energy heat pumps and hot water producers such as solar collectors can not act as liquid-gas boilers and can not meet the demand immediately. In this case, the hot water must be stored and ready for use for immediate demands.Combi boilers and thermal balance tanks are the products that answer this need.
Kombi Boiler and Serpantinli Kombi Boiler
Kombi boilers save space locally by carrying out the storage of the water coming from the heating system and the production of the hot water which goes to the shower and the taps in a single device. At the top level heat insulation is done. While the boiler water and the working water do not mix, the heat is transferred to each other. In the serpentine combi boilers, solar energy also contributes to the whole system.
The water circulating in the solar collector is connected to the coil. Thus, this water, which is specially added, does not interfere with the waters of other heat producers. There are 9 types between 500 liters and 2000 liters. The pressure resistance on the heating side is 3 bar and the hot water side is 10 bar. The surfaces that come into contact with the use water are enamel, the other inner surfaces are black steel sheet.
Thermal Balance Tank
The thermal equilibrium tank is heat-insulated at the high level, and is a pressure resistant water tank. Accumulation has a similar function to our tank. The differences table is below;
| Accumulation Tank | Thermal Balance Tank | |
| Internal surface coating | Enamel | No Overlay |
| Pressure resistance | 10 bar | 3 bar |
| Water connection | 4 pcs | 9 units |
| Sensor / thermometer connection | 2 units | 4 pcs |
• A solid fuel boiler or heat pump can not respond immediately to sudden heat demands from the heating system. This need is eliminated by the hot water stored in the thermal balance tank.
• Provides the collection and distribution of hot water in a single volume, where multiple heat sources will feed the installation.
• Efficiency in condensing systems increases as the return water temperature decreases. This is achieved by removing the return water from the coldest part of the temperature stratum formed in the thermal equilibrium tank.
• There are 10 types between 100 liters and 2000 liters. The pressure resistance is 3 bar. The inner surface is black steel sheet.
