| Water tank with indirect heating:VTI Variants with 100, 120 and 150 liters! | |
The water tanks with indirect heating are heaters, where the heating is produced by a primer warm water from an outer (e. g. a standing or wall-mounted) boiler. The time of the heating is relatively short, that’s why there no temperature variation. This type is very useful with sun-collector systems.
- Long life and quick water heating
- The heating of the water happens with a heat-exchanger on the lower part of the tank and so it is possible to avoid formation of bacteria
- With a very good polyurethane insulation the thermal loss is minimal
- Duplex protection against corrosion: a very good enamelled tank and anodic bar from magnesium
- Easy use and maintenance
- Excellent performance
- It is given the possibility to build in an electrical heater, available on the market
