About Solar Hot Water

Through the installation of Sun King Inc.’s products you can create a system to heat and transport water for a variety of commercial and residential uses including:

The sun’s energy is harnessed through both active and passive means described below.

Passive Solar Water Heating/Collection
Passive systems differ from their active counterparts as they utilize gravity to deliver and circulate water throughout the system. They include both direct and indirect systems. Based on their simplicity in design and lack of mechanical or electrical parts, they tend to be easy to repair and overall less expensive to operate. 
Active Solar Water Heating/Collection
By incorporating pumps to circulate, heat, and collect water active systems also include direct and indirect designs that take advantage of electricity. While active systems are more efficient than passive ones, they are more complex when it comes to repair and installation,  which means they tend to have more maintenance.
The Solahart L Series is a roof mounted, open circuit solar water heater specifically designed to provide economical service in medium to high solar gain areas.
The L Series is ingenious in its simplicity. The black polyester powder coated aluminum or copper absorber collects the sun’s heat and transfers it to the water in the risers. Copper is used for the risers for its high thermal conductivity ensuring the maximum amount of heat energy is passed to the water. As the water in the risers is heated, it rises into the tank to be replaced by cooler water from the tank. The solar heated water is then stored ready for use - hot water free from the sun.

The L Series has a double coated ceramic lined tank with a protective sacrificial anode. The L Free Heat features additional anode protection.
L and L Free Heat systems can be installed with an optional TRV over temperature protection system to prevent over performance during periods of higher solar radiation and lower hot water draw off.

The Solahart MDV series is an open circuit split system solar water heater with roof mounted slimline collectors and a tank that can be installed discreetly on the ground. It is suitable for use in low to high solar gain areas.
The MDV solar storage tank systems provide an increase in solar energy savings. Solar energy is transferred directly to the water as it is moved through the collectors by an electric circulator and the heated water is stored in the ground mounted tank.
This system is available with two types of solar collectors to harvest the sun’s heat and transfer it to the water. The higher efficiency CSA2007 Envelope collector with its sputtered selective surface copper absorber plate is suitable for use in lower solar gain areas and the L collector with its polyester powder coated copper or aluminum absorber plate provides economical service in medium to high solar gain areas.

Copper is used for the risers in both types of collectors for its high thermal conductivity, ensuring the maximum amount of heat energy is passed into the water.
The MDV series electric boosted models are equipped with an in-tank element to ensure a supply of hot water during periods of poor or no solar gain. Alternatively, this system can be installed as a preheater with an inline Solahart gas booster water heater.
