WALLY – W – has all pipe connections elegantly hidden underneath, and a slim diameter makes it especially suitable for hanging on the wall.WALLY can also be placed on the floor thanks to its unique design. WALLY can be placed close to the ceiling and save floor space with the wall bracket. Capacity can be increased by raising the temperature in the water heater to 75 °C, by using the externally adjustable thermostat. Outgoing temperature 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 resembling 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 features low heat loss with 40 mm. PUR insulation, in combination with class-leading storage temperature for unbeatable performance and more hot water.
