This is an installation where one Spirflame® is "locked" into a cellar and gas is piped through fix installed stainless steel pipes (inner ø 8 mm, wall 1 mm) to various places distributed over several building levels. Almost since 10 years a well known music instrument retailer with repair facilities operates such an installation in the midst of the old city part of Zurich in an restored historic building prohibited to store pressurized gas sources.

Every working station has its own Booster.

True "gas from plug in socket" is also now found at this companies other two locations. More tech details available on request.
