Big Fin-D™ Double Plate Absorber

This product is an indoor water heater that can be configured both PASSIVELY (solar application) or ACTIVELY.

Big Fin-D™ Double Plate Absorber (Patent applied for) is the new version of the extruded Big Fin™ Absorber Plate that Zomeworks began selling in the ‘70s.

Parts

• Tank
• Tubing
• Aluminum fins manufactured by Zomeworks (see pdfs below)

The new Big Fin-D Double Plate Absorber consists of two paintable aluminum plates formed to be bolted together over a copper tube. The resulting absorber is 8” x 48”, 2.67 sq.ft.

Configuration

Big Fin-D™ is intended to be installed behind or beneath south facing glazing inside a greenhouse or building. It can be arranged behind any type of glazing to heat water for domestic use, space heating, greenhouses, or for hot tubs or swimming pools. Configure the Big Fin-D in one or two long lines, many short rows, and horizontally or vertically. This flexibility allows the collector to be designed to suit the space available.

Sizing & Purchase

In sizing a system, a simple rule of thumb to use is: approximately one square foot of Big Fin will heat one and one-half gallons of water per day in a sunny climate.

FREEZE PROTECTION is entirely the owner’s responsibility. Zomeworks assumes no liability. Inside collectors can freeze even when air temperatures about them are above freezing. To monitor fin temperatures, rest thermometer against outside of absorber, the glazing side (or use an IR scanner). Check temperatures before the sun strikes the glazing. Drain if temperatures are likely to fall below 40ºF or provide freeze protection bleed valve. (Available at Therm-Omega-Tech (www.thermomegatech.com).
