Two gshp horizontal slinky systems were installed in Council owned premises. The first was a retrofit to the existing air handling unit serving a meeting room. The requirement was not only for heating but also cooling. The second system was installed at a recreation centre and provides underfloor heating to a restaurant and toilet block as well as the warden's first floor flat.
