OSO WALLY W

Wall-mounted hot water cylinder with all connections below

WALLY-W – has all pipe connections at the bottom and a slim diameter makes it especially suitable for hanging on the wall, although it is also possible to place it on the floor. Because all installation takes place under the water heater, WALLY can be placed close to the ceiling and save floor space. Increasing capacity can be done by raising the temperature in the boiler to 75 °C, using. the externally adjustable thermostat. Temperature at the tapping point will be approx. 10 °C lower than the thermostat setting due to the patented and integrated mixing function. Practical flex hoses for easy installation included. The supplied safety valve must be mounted on the cold water inlet.

WALLY has a stylish design in the family with the SAGA series, which hides all pipes and connections. The patented mixing function lowers the outgoing water temperature and reduces the risk of scalding. WALLY has the market’s lowest heat loss in its class, in combination with high storage temperature for unbeatable performance and more hot water.

WHY CHOOSE WALLY?

  • Save floor space with a slim diameter and all connections below
  • Save approx. 250 kWh / year in relation to good, insulated boilers (100 L)
  • Wall bracket included
