Product Announcement?- Vitosol DHW Solar Pack

Domestic Hot Water Rain or Shine with the Vitosol S-Pack

Viessmann’s DHW S-Pack (Solar Pack) is ready for both hydronic and non-hydronic heating applications with the introduction of the Vitocell CVSA solar tank which utilizes an electric element for the backup hot water. The S-Pack is an SRCC certified, single tank Solar Water Heating System that comes with preassembled components for a simple, quick and easy installation. The pump station, solar controller and expansion tank are pre-mounted on the 69 gallon tank and require only two final connections. The solar array acts as a primary heat source, and the high capacity 4500 watt electric element helps to make up the difference in times of high usage or low solar exposure in every region of the U.S.
