SOLAR HOT WATER PRODUCTS

Butler Sun Solutions Solar Heat Exchange Wand

1. Solar Heat Exchange Wand (Patent Pending)
The Butler Sun Solutions Solar Wand allows readily available, standard hot water tanks to be adapted quickly and easily for solar heating. The Solar Wand is a double walled heat exchanger that fits into any full size, 40 gallon and up, domestic hot water tank. It screws into the outlet port of a standard hot water tank. It provides a new hot water outlet and new solar collector fluid input and output connections. The Solar Wand has about two square feet of heat transfer surface inside the tank. The solar collector fluid, usually a mixture of propylene glycol and water, is isolated from the hot water by two copper walls and the space in between is vented outside of the tank. SRCC OG-300 Certification still pending.

The Solar Wand allows the solar system installer to use the existing hot water tank and a single pump to circulate fluid from the solar collector to the Solar Wand. Hot water tanks with built in heat exchangers are not usually available at water heater retail outlets.

When the hot water tank fails after many years of normal use, a new tank will be installed and the Solar Wand transferred from the old tank to the new tank during installation. Homeowners can install the Solar Wand and solar collectors themselves saving money. Professional installers will save time and effort.

1a. Sparco Anti-scald Valve
Keeps hot water out of system at 120-deg F maximum. Meets new building code requirements. A must for solar systems.

2. Integrated Over Temperature / Over Pressure System (Patent Pending)
The unit includes its own radiator and fluid overflow and recovery tank. Compression 3/8-inch tube fitting to the collector is on the left end. Finned Copper radiator provides for heat removal from collector if pump stops. A standard automotive radiator cap is used to vent into and recover fluid from the bottom of the fluid overflow recovery reservoir tube on the right end. A filler plug in the reservoir allows the fluid level to be checked and filled if needed.

3. Collector Umbilical and Split Pipe System
The collector, 3/8-inch copper tubing, fluid out and return lines are run together inside a single insulating layer of split rubber foam insulation. The electric control wires are taped to the outside of the foam insulation. The entire umbilical is protected by 2-inch inside diameter standard ABS drainpipe. The pipe is split and spliced to easily snap together. The picture shows the split pipe on the lower right, coming up into a 2-inch ABS pipe coupling. A 90-degree split elbow is used to turn the umbilical 90 degrees. Another ABS pipe coupling is used to connect the next straight section of ABS pipe, which has the top ABS pipe half removed to show the wiring, insulation, and tubing inside. The ABS pipe protects the umbilical from UV radiation from the sun, and can be painted to match the roof. It is weather resistant, but not sealed, so holes must be drilled to prevent water accumulation in the umbilical.

4a. Fireball 2001 Solar Collector
At 18-inches by 12-feet, each of the two 20 square feet (each) solar collectors comes in a variety of colors to match your roof! Double polycarbonate glazing, selective coated all copper absorb, aluminum frame. SRCC Rated.

4b. Multiple Tube Solar Collector
Thermomax Evacuated Tube collectors installed in Victoria, BC. The Solamax Collector is a highly efficient and works especially well in the northern latitudes, where there is a lot of cloudy weather. SRCC rated.

5A. Hot Water Tank, Wand, Pump, Wiring View
Collector fluid from the wand is plumbed to the pump inlet, with 3/8-inch copper tubing. A 1/4-inch fill valve is also on this pump inlet line. The pump outlet goes to a pressure gage and then to the collector via 3/8-inch tubing. The collector return line, also 3/8-inch tubing, runs with the collector outlet line in the same insulating foam jacket. The collector return line goes to the top inlet of the wand. Control wires fit outside the insulation. The hot collector return line goes to the upper wand connector.

5B. PV Pumped Hot Water System
Note the compact size of the PV pump. PV panel mounts on the roof and wires run down with the umbilical.
