SOL 25 PLUS Flat Plate Solar Collector

Maximum efficiencies
The SOL 25 PLUS is a highly efficient thermal collector. The net absorber surface of almost 28 sq feet results in a maximum output of 30,000 btu/clear day per panel. The SOL 25 PLUS also offers features such as a high selective absorber coating, low-iron, tempered solar glazing, and very effective insulation around the absorber plate. The internal fluid tubes are copper.

Appealing design
The SOL 25 PLUS has less depth than other panels, making it visually less obtrusive and compatable with exsisting architectural designs.

Installation time is minimized
The large panel size and the availability of a full complement of custom designed mounting accessories minimizes the installation costs.

Lasting and reliable energy saving investments
Stiebel Eltron uses only the most durable materials. The SOL 25 PLUS is the culmination of over 30 years of experience in the thermal solar business.

Features:

• High selective Bluetec CERMET ceramic/metal coating
• Copper absorber with copper fluid tubes
• Low iron tempered solar glass
• Durable corrosion resistant aluminum frame
• Low profile at 3" thick
• Complete line of accessories and mounting hardware is available
  

Applications:

• Residential water heating
• Commercial water heating
• Space heating
• Swimming pools

Single or dual heat exchangers
The Stiebel Eltron SB/SBB series water heaters are indirectly fired and are equipped with either one or two large heat exchangers. The heat exchangers are heavy gauge steel with procelain enamel coating.

Flexible options
The models with a single heat exchanger can be used for solar applications with some form of external backup heater. On the models with dual heat exchangers, the upper coil is typically connected to a space heating boiler fired by any fuel and the lower coil is connected to the solar panels.

Multiple uses
All Stiebel Eltron SB/SBB series water heaters can also be used as high capacity indirectly fired water heaters in conjunction with any type of heating boiler.

Features:

• Low standby heat loss
• Heavy gague steel with porcelain enamel coating
• Superb quality results in long service life
• Fitted with one or two large heat exchangers
• Sacrificial anode rod with wear indicator
