Solar Water Heating

When designing a new home there are several Solahart options available, which will seamlessly incorporate into your plans and ensure the solar water heater does not interfere with the aesthetics of your new home.

Option 1 The Kf and Free Heat Series
The standard unit is the 300 litre 302Kf (5 year warranty), or the premium 302K Free Heat Series (10 year warranty) with two panels, suitable for family sized homes with up to 5 or 6 people. Alternatively the 180 litre 181Kf or 181Kf Free Heat with one panel is recommended for small dwellings with 2 or 3 people. All have a 3Kw element as a backup for prolonged periods of overcast cold weather.

This can be fine tuned to your particular hot water usage with a time switch or solar monitor if required. Alternatively gas boosting, wetbacks or other alternative fuels may be used.

The horizontal Solahart cylinder is located either on the roof, or inside the roof if there is sufficient space and above the level of the top of the solar panels to allow the thermosyphon to operate.

New houses, subject to roof pitch criteria, may have the horizontal cylinder concealed inside the roof out of sight.

No pumps are required on these Solahart models, which ensures they are unaffected during unexpected power cuts or off peak power restrictions.

The Solahart cylinder is the only hot water cylinder you need. No other is required, freeing up valuable floor space inside your house.

Option 2 The Streamline Series
Instead of having a storage tank on or inside the roof, the streamline tank is installed out of sight at ground level. All that remains up top is Solahart’s unobtrusive low profile solar collectors. This allows you to enjoy the benefits of Solahart's advanced solar technology—the efficiency, the savings, the environmentally friendly attributes, all without having to interfere with the aesthetics of your home.

Wetback Connectivity
Wetback connections can be added to boost the Solahart Kf series during the winter months. Note the Streamline and Free Heat Series are not suitable for wetback connections.
