Buffer LEMET HPDS 250/100
Catalog number: 27.250SE|
Advantages:
- High heating power - thanks to the implementation of a spiral coil pipes, with large heating surface area, which guarantee fast water heating
- Dedicated - to heat pumps and gas-boilers. Water can be additionally heated up by an electric heater which can be optionally installed.
- Durability - is ensured by a magnesium or titanum anode and ceramic enamel, fired at 850 °C
- Insulation - made of polyurethane foam.
- Aesthetic Housing - made of leatherette. Available in 3 colour versions: grey, red and dark blue
