SUN-LITE® THERMAL STORAGE TUBES

Question: Is your greenhouse or sunspace too hot during the day and too cold at night?

Answer: Add thermal mass with Sun-lite® Thermal Storage Tubes.

Water contained in low cost, non-pressurized cylinders has proven to be the most practical and effective approach to the capture and storage of thermal energy for space and hot water heating. With over 35,000 units in use worldwide, Sun-Lite® Solar Storage Tubes are the most efficient and cost effective way to store solar thermal energy.

Proven, Low Cost Solution

Low cost containers designed to be the most economical per gallon of storage; Containers transmit natural daylight; Wide selection of diameters and heights available to compliment any design; Corrosion free fiberglass construction; Faster usable B.T.U. gain in 60% less space and 80% less weight than with rock or masonry; Self supporting containers require only flat, level floor; Easy to install or remove; largest tubes weigh less than 20 lbs. empty! The Solar Storage Tubes can be used in residential, commercial, industrial, and agricultural applications. Designs based on the following concepts have been proven to provide up to 100% of space heating and hot water needs depending upon climate and site conditions.	Direct Gain Clerestory
Direct Gain Water Wall Installed adjacent to a solar window, the tubes absorb solar energy, store the energy, and transmit natural daylight. The tubes temper both the heat and light from the sun by removing the wide temperature fluctuations common to other direct gain systems, and by reducing glare from the solar window to workable levels. The tubes may be filled with dyed water to increase absorption efficiency and to provide design versatility.	Direct Gain Vertical Wall
Controllable Passive A direct gain design can be modified to separate the Solar Storage Tubes from the adjacent heated space to provide more control over heat gain. movable or fixed, opaque or light transmitting partitions are employed, depending upon design requirements. Heat built up in storage is extracted by natural convection and/or a low power fan Wall application: Solar Storage Tubes are positioned adjacent to a multi-layered solar window with high solar transmision and good insulation such as our Sun-Lite Glazing Panels. In very cold climates, movable insulation should be considered, analyzing the trade offs between additional costs and B.T.U.'s saved.	Direct Gain Sloped Wall
The Solar Storage Tubes are normally filled with black dye in this configuration and placed vertically. Air for heat extraction flows either horizontally or vertically over the tubes. A wall application provides natural shading in the summer to reduce overheating.	Controllable Passive Wall
