The Solahart Free Heat Series

... taking the best and making it better

That was the simple philosophy behind the development of the NEW Free Heat Series. Solahart has taken the tried, proven, super efficient and ultra reliable K Series and made it even better.

That's right, the 'K' Series is even better. By using some of the latest technology and materials Solahart as lifted the performance  of the whole system. Improved insulation in the storage tank and the collectors has dramatically reduced the heat loss from both. Increased surface area of the glass exposed to the sun allows more sunlight to hit the absorber plate, thereby increasing the heat energy transferred into the water. The standard Solahart anode was replaced with a long-life heavy duty version and we are offering the Free Heat with a conditional 10 year warranty (10 Years on the Cylinder and Collectors, 5 Years parts and labor).

The Free Heat makes a quantum leap in performance and reliability over other systems on the market. It delivers premium performance in areas with low to medium solar radiation, areas with poor water qualities, or areas with frost or snow conditions.

So what does this means to you? Unparalleled performance! Extraordinary reliability! And lots and lots of steaming hot water, heated free by the sun!

So in areas where there?s heavy winter conditions you can be confident that the Solahart Free Heat series will deliver piping hot water, and, depending on where you live and how much water you use, the Free Heat series could deliver 50% to 90%* of your water heating energy consumption, free from the sun.

The secret to the Free Heats outstanding performance is Solahart's revolutionary multi-flow collector panel and our superior Black Chrome Selective Surface. Traditional fin and tube collector design means that there is a limit to the number of risers that can be effectively incorporated in the panel, generally 14 or less and typically less than 10. Therefore, there is a limit to the water way surface area exposed to the sun's energy.

Not so with our multi-flow design!  We have pioneered, and patented, an advanced collector design that uses a huge 35 risers to extract the maximum amount of energy from the sun. A cross section view (left) shows that our fully flooded multi-flow collectors (top) expose far more water to the sun's radiation, meaning this energy has a relatively short distance to travel to reach the water, when compared to traditional fin and tube designs (bottom).

The color and physical properties of the surface of a solar panel are significant factors in its performance. It is no surprise then that the secret to the Freeheat's outstanding performance is its Black Chrome selective surface.

Solahart uses two electroplating processes to apply the selective surface. The steel absorber panel is plated with nickel, and then with chrome, in a process much like any other standard metal plating process. The nickel plating provides a corrosion proof finish upon which the Black Chrome surface is electroplated for high efficiency energy absorption.The electroplated Black Chrome is superior to other selective coatings which are typically based on stick-on films.

This means Solahart collectors are heating the water faster and more efficiently than ever before, saving you more money, faster. In fact, so efficient is the Free Heat that in areas with high solar radiation the summer performance is so good that we recommend fitting a heat dissipater unit to control the water temperature inside the tank.

And remember, no conventional hot water system pays for itself, like your new Solahart does.  Your savings with a Solahart continue year after year. After you recover your initial investment, the savings are yours to spend on yourself and your family.

Not only will you save money with a new Solahart, you'll be playing an important role in saving the environment.  Your new Solahart gives you a practical way to reduce the greenhouse emissions in our atmosphere by up to 4 tons per annum. That?s like removing a small car from the roads every year!

The Free Heat Series Explained

The Free Heat series is a closed circuit system, utilizing a jacketed tank and heat transfer fluid; water is only held in the storage tank. The fluid in the collectors and jacket forms a closed circuit, and is a mixture of Solahart Hartgard® and water. The Hartgard® is what gives the anti-freeze and anti-corrosion properties to the fluid. The fluid uses the Thermosiphon Principle to transfer its energy into the storage vessel to heat the water.

The superior construction of the Free Heat system along with its  conditional 10-year Warranty (10 Years on the Cylinder and Collectors, 5 Years parts and labor), give you the peace of mind that your new Solahart is built to last and that it will be supplying you piping hot water for many years to come. Not only that, but with the standard electric, or the optional gas booster, you'll have hot water even on the cloudiest days.

The storage tank is constructed from 2.5mm steel, has 2 coats of Solahart's proven Primaglaze® enamel and a heavy duty sacrificial anode. This combination is a major breakthrough in Corrosion Control that protects your new Solahart tank from the harshest water.

To ensure your water stays hotter, longer, Solahart uses a thick layer of pressure injected Polyurethane, CFC free, insulation between the premium marine grade aluminum outer case and the tank. In the collector panels Solahart insulates the absorber plate from the outer case with an insulation batt, not unlike those used in household roof insulation. These two measures work to minimize heat loss from the entire system, saving you money and giving you piping hot water 24 hours a day, all year round.

The Free Heat collectors have been developed over many years and provide excellent solar absorption. The absorber panels are made from pressed steel plates formed into a fully-flooded multi flow pattern. This means that the fluid that travels through the collector is in direct contact with far more of the absorber plate than open circuit collectors greatly enhancing the systems performance. The surface is coated with a Black Chrome selective surface and housed in a marine grade aluminum case, with glasswool insulation, and low iron tempered glass.

This unique arrangement provides a number of benefits: since the collector circuit is filled only once, it is not susceptible to clogging or corrosion as a result of poor quality water supplies; since the collector fluid will not freeze, the waterways are not susceptible to rupture even under the coldest conditions.
