STS+

Solar collectors with cylinder - natural draft
READ MORE

STS+ solar collectors exploit solar energy for domestic hot water production.

STS+ is a range of vertical natural-draft solar collectors, ideal for combination with other Baxi productsfor the creation of highly energy efficient integrated systems.

STS+ is supplied with a 150, 200 or 300-litre storage tank and can be installed either on a flat or pitched roof.

Characteristics
  • Pre-assembled natural circulation solar systems for DHW production made of solar collector "Mediterraneo Slim", solar cylinder, universal frame and hydraulic connection kit
  • Ease of installation and maintenance: "Mediterraneo Slim" is the thinnest panel on the market (46 mm) and extremely light weight (only 26 kg for STS+ 200  and 32 kg for STS+ 250) 
  • Hydraulic connections with insulated copper pipes and compression fittings connections to the cylinder included
  • 150, 200 or 300-litre enamelled steel cylinder included
