Solar Power Hot Water Heating Freeze Protection Kit GH (Glycol Closed Loop with Stainless Steel Heat Exchanger) 

If you live in an area with freezing temperatures in the winter, look no further than the GH system. It offers freeze protection to -17o F so you'll always have ample hot water for those relaxing hot showers in the cold winter months. However, if you live in an area where it doesn't freeze, check out the EZ-Connect kit

The kits include EZ-Connect panels, a stainless steel compact heat exchanger, and glycol, which is a heat transfer fluid. The panels only take minutes to install, and the kit uses a standard 1/2" Copper, CPVC, or PEX pipe for connecting to your existing water heater.

The GH System uses a Stainless Steel Heat Exchanger with a special food grade heat transfer fluid (DOWFROST) to create a system that can operate trouble free year round. Please use the Glycol Calculator to determine the dilution ratio for winter conditions in your area as well as the total amount of glycol concentrate you need (2 Quarts are included).

The panels are relatively light, weighing a little over 12 lbs. By using this kit you DO NOT have to solder at all!

Each kit comes with:

  • EZ-37 Panels (Kits available from 2 to 10 panels)
  • 1 Grade A 20W PV panel to power the pumps - NO grid connection required - plus wire and PV mounting kit
  • 1 TopsFlo TS5 15PV Pump for the Glycol Side
  • 1 TopsFlo TD5 Stainless Steel Pump for the Water Side
  • 1 Heliatos Glycol Fill Valve
  • 1 Heliatos Bottom Feed Connector
  • 1 Compact Stainless Steel (Alloy 316) Heat Exchanger
  • 1 Extrol Expansion Tank
  • 1 Complete Set of Fittings and Adapters
  • 2 Quarts DOWFROST Food Grade Propylene Glycol Heat Transfer Fluid
  • Installation Instructions Booklet

How many panels do you need?

  • 1 panel for every 10 gallons of water heater capacity. You can select the number of panels above the "Add to Cart" button. This kit is available up to 10 panels - enough for a 100 gallon water heater. 
  • If you have a good south facing site for the array that is also very close to the water heater (15 ft or less) you can also go with one panel for every 12 gallons of water heater capacity.
  • We recommend adding one more panel if the panels will be placed at a long distance (25 feet or more) from the water heater. For example, if you have a 50 gallon water heater that is 40 feet from the panels, we recommend getting 6 panels.

All You have to supply is:

  • Your choice of 1/2" Pipe from the panels to the water heater (Copper, CPVC, or PEX)
  • Fasteners to attach the panels to the roof, and the parts to feed the pipes through the roof if needed. You need to make sure you know how to mount the panels to whatever surface you have and get whatever hardware is necessary for the particular mounting style you have in mind (screws, rails, mounts for metal roofing if applicable etc.). This is meant by fasteners.
  • Insulation for the pipes.
  • Your existing Water Heater
  • Tools needed for installation

This product fits any existing water heater with a "boiler drain" near the bottom. This includes almost all gas and electric powered residential units. 

Please Note - Will NOT work with Marathon Non Metallic (Plastic) Water Heaters.

When the shipment arrives, the driver will ask you to sign for the delivery. This is a legal document stating that the package is being delivered in good condition without damage and that you are waiving any additional claim from the shipper. Before signing, inspect the package(s) closely on all sides. Note any damage, including scuffs, dents, tears, punctures or creases on the delivery receipt. If you sign for damaged goods without making a damage notation, we may not be able to help you persue a damage claim. Your signature on a shipping receipt is a legal release of claim for damage unless noted at the time of receipt. So check your delivery carefully.

If there is anything unusual with the package, you have the right to open it to inspect the contents. If the driver is unwilling to wait while you inspect all of the items, you may mark on the delivery receipt “Concealed Damage Possible”. If there is damage to the shipment, then you must contact SolarTech Direct immediately.

Order Cancellation Policy:

A $50 administration fee will be applied if you cancel your order after 48 hours regardless if your order has been shipped or not.

QUESTIONS & ANSWERS

Ask a Question
  • With the GH freezes protection system, how efficient is the supply cold and return of heated water in the same location? Can you run the return heated water to Cold water inlet line at the top of the tank?

    The bottom feed connector is a specifically designed part to make the connection of both hot and cold very efficient. They are not really the same connection as they are internally separated. However if you want to use the classic "top connection" method you can. It is slightly less efficient than the connection through the bottom feed connector. We should also note that while returning the heated water to the cold connection is possible in the classic top connection scheme it is far more common to connect it to the hot side. Commonly the feed to the panels is taken from the cold port on top or the drain at the bottom and the hot is returned to the hot port on top.

  • How many panels do I need for a house with 3 full bathrooms and kitchen ??

    It depends on the size of your water heater. The recommendation is 1 panel for every 10 gallons of water heater capacity. If you have a good south facing site for the array that is also very close to the water heater (15 ft or less) you can also go with one panel for every 12 gallons of water heater capacity.
