Indirect systems water is heated directly into solar collectors and circulating in your home.
Solar water heating system types.
In an indirect system solar energy is collected and held in a special antifreeze fluid.
However passive systems can be more reliable and may last longer.
The antifreeze is circulated into your hot water storage tank which heats water for use in your home.
Passive solar water heating systems are typically less expensive than active systems but they re usually not as efficient.
Passive solar water heating systems.
Collector based systems the first two types both use a solar collector that is placed on your roof.
An estimated one million residential and 200 000 commercial solar water heating systems have been installed in the united states.
An active solar water heating system consists of 3 major elements a flat plate solar collector and a solar energy hot water pump.
Although there are a large number of different types of solar water heating systems the basic technology is very simple.
Integral collector storage passive systems.
There are two basic types of passive systems.
Active solar heaters are primarily of three types direct indirect and drain.
There are 3 types of solar hot water system to choose from.
The water tank of a thermosyphon system itself usually does not require any pumps and controllers to operate in its simplest form using the pressure of the water connection in house would allow the system to operate effectively as an on demand hot water system heating the water in the tank to well over 60 degrees under fair conditions.
It is best suited for cold or freezing conditions where the absence of heat exchangers means that cold cold water cannot be heated effectively.
The 3 types of solar hot water.
This system is used if the tank is bellow the collector e g when concealed under a slanted roof.
The main difference between direct and indirect solar hot water is the type of fluid used to collect heat in the system.
