It can be quite expensive to heat your home with gas or electric. People are starting to look at the alternatives to help save them money. Solar water heating systems are a nice alternative. An added bonus with a solar powered system is that it is using a renewable, non-polluting energy source. Choosing a solar water heating system just makes a lot of sense.

A solar water heating system can be passive or active. This refers to how the water is heated within the system. As the names suggest, passive systems require less equipment then active systems. Passive systems also do not require a lot of water movement, where active systems move water more often.

A passive solar water heating system does not contain moving parts and requires nothing more then the solar energy to operate. The water system is mainly a tank on the roof. It should be in a spot where it will have good sun exposure. This tank is usually painted black and made of a metal that will conduct the heat. The tank is where the water is heated and it is then pumped out as needed to wherever in the house.

An active solar water heating system requires the use of an additional energy source, such as electric. It uses solar panels to collect the solar energy and stores them in a battery block. As the energy is extracted from the battery or the panels an electrical heating system is needed to help warm up stored water.

Both passive and active system will help reduce energy costs. However, with the unreliability of solar energy, passive systems can require some type of back up in case there is just not enough solar power. Additionally, active systems may require more maintenance since it has many more parts to it then a passive system.

Overall, any type of solar water heating system is going to help reduce reliance on energy sources that are quickly becoming depleted. It is solar energy that seems to be the most promising choice as a replacement form of energy that is abundant, free and easy to use. The purchase of either an active or passive solar water heating system is going to be a good buy. You will be happy with your purchase because it will pay for itself over time, unlike any electric or gas water heating system.
