Solar heaters are a great way to trim down the heating costs of a swimming pool. These cost effective pool heaters have very low operating costs and are available in the variety of gas pool heater and also heat pump pool heaters.
As a matter of fact, solar pool heating is the most profitable usage of solar energy and can be accomplished in most of the climatic conditions.
Some of the fundamental components and their key function in a solar pool heating system is explained below:
1. A solar collector is used to circulate the pool water in a strategic manner, in front of solar rays, so that it can absorb the heat and get warm.
2. Water pumped through the collector is passed through a filter to remove any kind of wreckage present in water.
3. A pump is used to push the water collected from the filter, back into the pool.
In order to pass the pool water through the solar collector, a flow control valve is used so that the water doesn’t flow back into the pool without passing through the whole solar pool heating system.
This system of solar heating works efficiently for pools during the cold winter months by running the water through collectors and filters during the sunny day. However, this system can also be used to cool down the water during hot summer days. You just have to reverse the cycle and pump the water through the collectors at night instead of day.
Most of the solar heating systems for pools are automated and contain a sensor or a valve, which redirects the pool water towards the collector, as soon as the pool temperature falls below the collector temperature. Once the temperature equalizes, the valve is turned off either manually or automatically and the water is returned to the pool without passing it through the collector.
Solar pool collectors come in a large variety and varying design structures. Your climate and usage of a solar pool collector significantly define the type of collector you will need. For using the pool in an above freezing temperature point, you will only need a non-pressurized pool collector system. A non pressurized collector system is made up of simple, inexpensive parts and mostly consists of a glass vacuum tube that has a selective absorbing coating on the outer layer. There is no copper heat pipe involved and therefore non pressurized collectors are economical and inexpensive as compared to pressurized collectors.
On the other hand, pressurized collectors consist of both glass vacuum tube as well as a copper heating pipe and so they are relatively expensive. Moreover, pressurized collector systems carry heat exchangers and transfer fluids which allow them to absorb more heat and work effectively during the extreme cold weather conditions. Pressurized collector systems can also work for domestic water heating while different climates and weather conditions do not affect their efficiency as there is no circulation of water in the collectors.
