ThermoPower: Silicon Solar offers pre-packaged solar hot water heating systems for both the do-it-yourself customer and the professional installer. Each system includes the primary components required when installing a solar hot water heating system. It is our goal to keep our product cost low in order to ensure that we are making renewable energy products more affordable to the community.

All systems have been tested under the highest quality standards in order to ensure the longevity of your solar heating system. If you are unsure of where to start or if you require guidance with your solar hot water heating system please feel free to contact a solar hot water specialist at 1-888-SOLAR-11.

Vacuum Tube Solar Collectors are extremely efficient and cost-effective particularly in colder climates where other Solar Collectors suffer from limited performance and other problems due to their lack of freeze protection. Vacuum Tube Collectors unlike others are extremely freeze protected leading to efficiencies of over 70% even in freezing temperatures. The unique design and collection properties of these collectors make them exceedingly efficient even in low-light conditions which is another definite advantage during winter.

SunMaxx Vacuum Direct Flow Solar Collectors are among the most affordable cost-effective solar collectors available on the market today.

Replacement Parts & Safety

Item Qty Description
ThermoPower-A-VDF-TUBE-18 1 Package of 18pcs; ThermoPower-VDF tubes, 47x1600mm. Replacement glass.
ProtectMaxx-GLYCOL-FG-50PCT-5G 1 High temp solar glycol, required to not void collector warranty. Pre-mixed to 50%.
XMaxx-HW-BUSHING-3/4IN-1/2IN 2 Adapter from ½” to ¾” (female NPT), makes easy to interconnect with line set quick connects.
FlowMaxx-A-3/4IN-3/4IN-PF-M* 4 FlowMaxx line set quick connects. Note, we connecting evacuated tube collector to ridge pipe, a thermal expansion compensator must be used to prevent unnecessary thermal expansion stress on the collector field connections. This can be accomplished be using a small section of FlowMaxx line set + quick connects, to build flexible connector. Note, if using all stainless steel pipe to connect the collector field; additional thermal expansion joint not required.
XMaxx-HW-UNION-1/2IN-F 1 For interconnecting multiple collectors together. Maximum number of interconnections without expansion joint (3 VDF20).
