Hot water cylinder SAGA EXPANSION – SE – is specially designed for homes with a non-return valve in the form of a water measurement (required in many municipalities), pressure reduction valve (should be installed at water pressure> 5 bar) or similar. Water that expands during heating is absorbed in the fully integrated expansion vessels and prevents loss of approx. 2,300 liter of hot water per year and drip from the safety valve. Pre-pressure on vessels must be set 0.2 bar below water pressure. EXPANSION should be selected over STANDARD if the home has a non-return valve installed.
SAGA is Norway’s best-selling water heater for several decades. Modern and practical design hides all pipes and connections. SAGA is easy to install with all pipe connections on top and is directly suitable as a replacement for OSO water heaters from 1980 without changing the pipe layout. The mixing valve lowers the outgoing water temperature and prevents the risk of scalding. SAGA has the market’s lowest heat loss in combination with high storage temperature for unbeatable performance and more hot water.
