OSO WALLY W
WALLY
Slim diameter and connections underneath for tight spaces
WALLY — W will fit into compact spaces due to its 430 mm. diameter, and is custom designed to be fixed to wall (wall bracket included) with all connections underneath the unit. WALLY's slim design ensures optimal stratification of hot- and cold water, and WALLY boasts high performance, as well as IP class 21. To comply with the ErP directive, the thermostat is factory set at 65 °C for 70 / 90 / 120 L (70 °C for 30 / 50 L), but an increase in capacity is easily done by adjusting the thermostat to 75 °C (NB: follow instruction manual when adjusting.)
WALLY is available in two versions, one version with simply a safety valve and another version with a factory fitted mixing valve with adjustable hot water draw-off temperature (prevents scalding) to the taps.
WHY CHOOSE WALLY?
• Reduce heat loss by 150 kWh* / year with NANOPUR*
• Custom-designed for wall mounting with IP class 21
• 5 year warranty on the stainless steel pressure tank
* Compared to 100 L cylinder with EPS insulation
