Thermal Hot Water

Solar Water Heaters use solar evacuated collectors to capture the sun’s radiations and converts it to thermal heat. The solar heat is then either transferred to usable energy or stored in a heat sink such as a large solar water tank. There are many types of solar thermal systems but the most advanced and efficient system is a closed loop system. Closed loop system allows the suns energy to be stored and released when needed by using controllers and pumps that allows home owner the comfort and control with virtually zero energy costs.

hotwater1Solar collectors produce significant amounts of heat energy and advanced high temperature solar system should be properly engineered. Spectrum Solar Solutions provides pre solar heating systems that are proven successful throughout the world. Caution should be used with “Home Made” Solar systems as they can lead to serious damage especially if using high efficiency vacuum tube collectors. Our systems are engineer with to provide maximum performance and safety.

 

Solar water-heating system has four main parts: (1) a solar evacuate tube collector and (2) a solar storage tank (3) Solar Controller and Pump Station (4) Special Solar Piping. Most common collector used in solar hot water systems was the flat panel collector. However with the advance in technology, solar vacuum tube technology is rapidly becoming the method of choice as its energy output is much higher and takes up less space area per square foot. Mass production of solar tubes has driven the cost down to allow widespread use of vacuum tubes.

Solar water heaters use the sun to heat either water or a heat-transfer fluid in the collector. The pumping station and controller causehotwater2 this hot fluid to circulate through the specially insulated solar piping and the into a solar storage tank that normally contains an internal heat exchanger which indirectly heats the mass of water. The tank can be as simple as a modified standard water heater, but more specific solar water tanks are recommended for better performance. Most solar water tanks will also feature a back up electric element built into the unit.

The main part of every solar water heating system is Solar Controller and Pump Station. This includes all items required to make the system function optimally and safely. Items such as temperature controllers, pumps, expansion vessels, pressure safety valves, fill and drain spouts are all part of a properly installed solar system. Spectrum Solar Solutions uses engineered and designed  pump stations with integrated  controllers. These systems are the core of any of solar systems, whether heating your house or a hot water tank, the solar controller & pump station is an important component. This pump station is a self contained pre-plumbed system that contains everything needed for a complete solar system. The System simply attaches to the hot and cold fittings at the collectors and attaches to the hot and cold fittings on your solar storage water tank. All specialty components are included and you simply plug the Solar Controller to a 110 VAC power outlet.

Perhaps the most over looked part of any solar heating system is the solar piping or “solar line sets” that tie the collectors, pump station, and solar storage tank together. Unlike Hydronic or radiant floor heating, solar thermal heating system gets much hotter and can quickly reach temperatures of 400 Fahrenheit. As such plastic tubing’s such as can never be used on the solar loop side. Proper solar line sets are critical to a trouble free installation. Spectrum Solar Solutions Kits use stainless steel flex able 3/4″ piping with a special high temperature insulation (3/4″). Also included on the line sets is a durable water proof membrane that stops the elements from damaging the insulation. One of the line sets will contain a pre installed temperature sensor wire that is used to communicate the collector temperature to the controller station. All our pre solar systems come complete with high temperature fittings that simply thread into place without the need for any soldering, which greatly reduces the assembly time and leaks.
