* Required fields
- DOUBLE HIGH OUTPUT HEAT EXCHANGER increases the efficiency of low-temperature heat sources.
- Decreased hydraulic resistance (pressure drop) of the heat exchanger with a larger diameter of the inlet
and outlet on G1 1/2. (160 L model with inlets/outlets on G1). - Heat exchangers with large surfaces for connection to heat pump or condensing gas boiler systems.
- Suitable to operation with low temperature heat sources.
- High quality ENAMEL COATING with TESY CrystalTech PRO technology.
- MAGNESIUM ANODES PROTECTION of the inner tank surface for extended product life.
- Highly efficient REMOVABLE POLYESTER INSULATION for models 800 L and 1000 L.
