Solar water heater system is an energy saving method that helps the environment by using sunlight to heat water. It can be installed directly or indirectly. There are several advantages of this type of heating system. You can save on your cost of ownership, but the biggest benefit is the savings you can get at every level of demand.
Direct vs indirect
When looking for a solar water heater, you’ll have to choose between a direct or indirect system. Direct systems use a single loop to heat the water and are suited for warmer climates. However, these are not as efficient as indirect systems and are more expensive. They also increase the risk of heating losses in the boiler.
Indirect systems circulate the collected heat from the collector to a storage tank in the basement. This reduces the chances of losing heat through the pipework. Unless you have a very cold climate, an indirect solar system is likely the better choice.
The most basic configuration is the thermosiphon. With this system, a hot liquid is pumped from the tank to a solar collector. Solar radiation heats the liquid and then it is pumped back into the tank.
Passive vs active
If you are considering investing in a solar water heater, you should know the difference between a passive and an active system. Active systems are the more efficient and cost effective of the two. However, they can be complicated to install. Hence, it is best to consult a professional.
