Solar Power Hot Water Heating Freeze Protection Kit 

If you live in an area with freezing temperatures in the winter, look no further than the freeze protected water heater 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 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.

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 25W PV panel to power the pumps - NO grid connection required - plus wire and PV mounting kit 
  • 1 Heliatos HS-17 Pump for the Glycol Side 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 Amtrol Expansion Tank
  • 1 Complete Set of Fittings and Adapters
  • DOWFROST Food Grade Propylene Glycol Heat Transfer Fluid. 2 quarts for kits 4 panels or less. 4 quarts for 5 panels or more. 
  • Installation Instructions Booklet

How many panels do you need?

  • Cold Climates: 1 panel per 6 gallons (Ex: A 40 gallon tank would require 7 panels)
  • Warm Climates: 1 panel per 10 gallons (Ex: A 40 gallon tank would require 4 panels)
  • Distance between panels and water heater over 10ft: Add 1 panel

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.

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.

      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.

      • Any reason these can not be ground mounted? If so do you sell a frame kit?

        According to the manufacturer, the panels can be mounted on the ground. They should be mounted at or near the optimal angle for your latitude facing south and should not be shaded during prolonged periods of time daily. Ground mounting is actually preferable as the wind loads are typically lower and maintenance (cleaning etc.) is easier. We do not sell a frame kit, but most people just make a rack or frame from standard lumber.

      • I live in St Petersburg, Florida. We can get one or two frosty nights a year 32-37F. Do i still need the freeze kit?

        You can get the non-Freeze EZ-Connect Kit, but you will have to drain the panels before any freeze occurs.  Drained panels will not be damaged by cold weather, snow, etc. If water remains in the panels during freezing temperatures, they will be severely damaged. If you have a freeze protected system, there is nothing you have to do.

      • Can you please let me know what is the solar fraction of this device?

        We checked with the manufacturer, and here is the response: "We can't really tell anybody what their solar fraction is because while we could tell the customer what amount of energy to expect from our system (given the specific system they are thinking of and the location and details of the installation) we cannot assess any other energy sources they are using. This is a frequently asked question because tax rebates depend on it. Our system by itself has a solar fraction of 100% since it is not grid connected, but using that number for the tax collector will probably get you in deep trouble because that isn't what they are asking for."

      • There are periods when there is no sun in my area. What can I use as a backup source to keep the kit running?

        All our kits hook up to an existing standard water heater so whatever original heat source they had will remain intact and can work as a backup. So if they currently have an electric water heater and there is a prolonged period of no sun the electric elements will heat the water until it is sunny again.

      • Can I still have my electric water heater hooked up to the grid in the event that I need to switch over from solar (like during several rainy days where there is no sun?) and will that affect either system?

        Yes most people leave their tank connected to the grid (or gas). The Heliatos solar water heaters do not interfere with whatever other source of heat you have already. Most people leave the grid off during the sunny months of the year, but then turn it on as a backup when it is less sunny.

      • 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.
