The benefits of Solar Pool Heating System

To run a heating system with the help of solar energy is definitely a future changing idea contrived by the scientists and the technologists who understand the galore of the possibilities captured in the Solar Heating system. As the concept was to use the solar energy through the conversion devices which has sent off a buzz in the market, where the solar heating has become the obvious and an easy choice for the general consumers who are seriously stressed out by the energy consumption bills at the end of every month.

The solar heating system offers an oodles of benefits that has made the technology a million dollar invention. 

Solar pool heaters run by the solar absorber which is tub on the roof to transfer solar heat into the pool water through passing the tubes. The solar system is a reliable system for all round the year. It works by making an availability of the lukewarm water in the pool by raising its temperature for 3 to 5 degrees above the usual temperature, by allowing you to relax in the pool for a bit longer and extend the summer season for several months. Since the systems are running under the solar heat, the water temperature will going to be warmed for the longer period of time. 

The sunlight is an energy resource which is free for all where the monthly expenditure of the devices used in the solar system are relatively very low. The initial solar pool heating cost is the same as the electronic versions, but the recurrent cost is far lower than the other electronic versions. Now we can say that warm water in your pool is available to you at the cost of running a solar pump. 

Some of the benefits are listed beneath that are reserved for the solar pool heating system. 

It will allow you to extend your swimming season up to 9 months of the year

It allows you to have a low running cost other than electric or gas

It adds a huge value to your home and pool

If you have installed with a coexisting filter pump then there will be no power needed to heat the pool

You can enjoy an automatic or the manual temperature controller for the pool water 

It will be an extremely quiet during the operation

It can easily install for the North, East or the Western roofs as well 

It can also be used with any supplementary heating system as well 

Its life expectancy is around 20-30 years. 

Which one is better PV or Thermal?

The solar thermal water heating is now a temperamental thing. Water has a lot of weight, it expands when it freezes and it caused a severe damage to the pipes when it boils. On the other hand, the solar thermal systems are wonderfully efficient and many of the systems are able to work perfectly for over the decades but if the regular inspection is given to them. When the solar thermal system fails and it has been clear to some point of time that the solar thermal water heating is expected for the very-low heat usage like the solar pool heating companies are offering. 

For a long time, the wisdom has been shown the relative efficiency advantage of the solar thermal technology for the water heating which outweighs availability of the electric water heating. The capacity of the solar thermal to collect more energy is powering a conventional electric water heater alone with the solar thermal system.

There have been reductions in the solar electric (PV) costs and there has been a maturation of air-to-water heat pump technology as well, which have provided a new model which is solar-electric assisted heat pump water heating that has the fewest drawbacks other than the solar thermal. 

PV Advantages 

Lower cost – we have seen that the lowest cost has open the system with a proven results for the domestic water heating where the installation cost of the solar thermal has to based on the closed loop with the two tank system and has to be fully installed as well. The average cost for this system has to be designed for the family of four in a minimum range of the price tag for the residential applications.

The use of a heat pump water heater with an efficiency factor for about EF of 2.5 and an 1,800 kWh per year rating where the grid of 1 to 1.3 kW of PV has been added to an existing installation system in a region. 

Easier to install – A water heater can be replace by another single tank and you can add three to five additional modules in the PV system is really convenient instead of replacing the two tanks and the pipes, where the heat transfer fluid to the heavy rooftop should be pressure tested and has to be charged after installation. This can be result in less opportunity for the installation errors to be taken place. 

Less space usage – the solar thermal system requires a backup source where the two tanks are required, the one for the backup and the other one is for the solar system. You cannot save the space, while eliminating the usage of tank heaters as long as the tank heater can regulate the heat flow to the really low point as well in order to meet maximum demand. 

Low maintenance – Even when the solar thermal system has stopped working, but it does not fail to produce the energy. The electronic controller and the circulator pumps have to be inspected on the yearly basis, which assure that they are functioning properly and there should not be any scale of the system corrosion which may lead to the system failure.

Solar System Services for water heating

In order to keep solar energy system operating efficiently, they need to be periodically inspected and maintained. For the period of the time, the components are required to repair and replaced. The precautionary measures should be taken to prevent freezing, scaling and corrosion. 

There would be some initial level of maintenance and inspection that can handle by yourself as well, but many people require qualified technician for that as well. Try to estimate the cost of the project before starting the work. In many of the projects it can be effective in terms whilst replacing them either you can shut off or remove the entire solar system than to have it repaired. 

There need to be a periodic inspection list which has to be done in order to make the working of the solar system service efficient. 

Collector Shading – check the shading of the collectors during the day either the mid morning or mid afternoon annually. Shading can greatly affect the performance of the solar collectors. The growth of vegetation over the time can also affect the shading of the solar system. The new construction can also be another factor for affecting the shading.

Collector Soiling – a regular cleaning is required for the soil collector in dry and dusty climates in order to prevent them from grime and dust.

Glazing and seals collector – examine if the cracks are there in the collector glazing, and see if the seals are working in a good condition or not. Plastic glazing, if it has gone excessively yellow then it has to be replaced. 

Wiring connections and plumbing – examine the pipes for the fluid leaks and check the duct connections as well. Ducts has to be sealed with a compound called mastic. The wiring connections should be tight as well. 

Wiring installation and piping – examine for the damage or any kind of degradation of the insulation compound covering the pipes, wiring and ducts. 

Roof penetrations – the roof penetration has to be in good condition while to examine the flashing and sealant around the roof. 

Support Structures – the nuts and bolts should be tight enough when attaching the collectors in order to provide a support structure for tightness.

Pressure valve – assure that the valve is not stuck closed or open

Dampers – assure that the dampers are close and open properly 

Pumps and blowers – verify the operation of the distribution pumps and blowers. Check if they come on while the sun is shinning on the collector after mid morning. If you cannot hear the pump or the blower after the mid morning then there might be the cause of malfunctioned either the collector or the blower. 

Heat transfer fluids – The antifreeze solution has to be changed periodically in the solar heating collectors in order to make them work properly and effectively. This task can be best done by the technician. If the water has reached the high mineral content whilst circulating in the collectors. This mineral build up has to be removed from the pipe by adding a mild acidic solution in the water in every few years.
