How do Solar Pool Heaters Work?

Pool Solar Panel

It's a frequent but true mistake to believe that solar heaters for swimming pools appear like photosynthetic (PV) solar panels for rooftops and utilizes similar technology. Both utilize the sun's radiation or solar energy to operate, however, they operate in different ways. We will show you how a solar pool heater works.

Solar heating systems for pools consist of a variety of types of equipment:

  • Pump and filter the pool.
  • Solar collector.
  • Control valve for flow.

Pump and filter for the pool

A majority of swimming pools have a filtering system in place and high-powered pumps already in place which makes it simple and less expensive to set up solar pool heating systems. The pumps collect the water from one side of the pool and transfer it to the solar panel heating. Once the filter is set up, you will feel secure knowing that the water is pure and will not be able to fill the interior of the tank with leaves or other debris of plants falling into your pool.

Solar collector

A solar panel heater, also known as a solar collector acts as the primary element of the system of solar heating for pools. It is responsible for heating the pool's water. From a distance, it appears like solar panels made of PV however, closer inspection will observe that it's made of tubes in a string that runs across the length of one end and another These tubes of heating tubing for solar heaters absorb solar energy to heat the pool water.

When cold water is delivered to the solar panels for the pool and then through the lower end of the tubes and absorbs the heat generated by the sun's rays while it moves upwards. Once the water has completed the entire process within the solar collector departs with a higher water temperature before moving to the next stage, where the control valve controls the flow.

Control valve for flow

A flow controller determines the proper speed for the water to return to the pool with a higher temperature. This is a great device in situations where the water flow rate of the pool exceeds 45-55 g.p.m. the ideal water flow rate for solar heaters for pools. It is possible to increase the temperature of your pool by opening the valve to direct flow to the collector or reduce it by reducing the water's flow.

The efficiency of the solar pool heaters

The effectiveness that the solar heating system produces will depend on the location and method you place the collector. It is recommended to place it in the south to the most optimal angle to get the maximum benefit from the solar energy. The level of radiation in your location can also impact the amount of heat that the solar heater generates.

What Should You Consider when choosing the best solar Pool Heaters

Pool Solar Panel

There are several essential aspects to be considered when choosing the best solar pool heaters, such as the size and type of pool in addition to the heater's longevity and the method of installation. Before you go, learn more about these and other crucial features of solar heaters for pools.

Type of Pool

If you're looking for an above-ground pool heater pool or an inside-ground pool is an element that can limit the choices. Solar heaters for pools are made for both above-ground and in-ground pools, and some are used with both. A small, freestanding solar heater could suffice to provide enough heat to an above ground swimming pools. However, in-ground pools of a larger size may require a larger solar heater that is attached to the roof of a house.

Since the best solar pool heaters work through a connection to the pump that is already in place It is essential to buy one that's rated to function with the pool's type. The majority of pool pumps are designed to work with above or inground pools but not both. The majority of inground pools utilize fittings of 2 inches, whereas the majority of above-ground pools utilize 1.25 or 1.5-inch fittings.

The types Solar Heating Systems for Pools

Another way to narrow the selection of a pool heater is to choose which type the solar-powered pool heater will be most to be used in the pool.  Best solar pool heaters are available in three types that include flat-plates, evacuated tubes, or batch collectors.

Flat-plate

  •  It is the most popular solar heating system for pools. A flat-plate collector is an enormous flat sheet of black polypropylene or hard plastic that absorbs solar's heat. The panels are usually affixed on rooftops of houses or on a rack that is placed in the ground. There are also freestanding units, which are mounted on a frame that has an appearance of glass or plastic with a clear top, and two legs. These permit the user to alter the angle of the heater. These panels connect to the pump of the pool through pipes and tubes. The water is pumped through channels that pass through the panels, warming the water as it flows through the panels before it is returned into the swimming pool.

Evacuated tube

  •  It is composed of two glass tubes, which contain an iron heat pipe connected to a fin that absorbs the solar heat. The fin is then able to transfer heat to the fluid inside the collection tube made of metal and then warms it. The name of this type comes because of the glass tubes that also vacuum because air is evacuated from them.

Batch

  •  Batch collector comprises a water tank or tubes that are encased in an enclosed box. The water inside the tube or tank is heated by sunlight before being recirculated back into the pool.

Size of the Pool

Since it requires longer to cook up a larger pool than a smaller one so the solar heating system must be big enough to be able to adequately warm the volume of swimming pool water. The typical space of the solar heater must be 50-100 percent of the surface of the pool to efficiently warm it.

Areas in which it is cooler or more cloudy require an area at or near 100 percent of the area of the pool while a smaller unit can be used in warmer climates and more sun-drenched. Solar pool heaters that have bigger surface areas are more likely to extend the season of your pool by keeping the pool's temperatures warm throughout the late fall.

The Mounting Type as well as the Install

Solar pool heaters are available in a wide range of ways to mount them. Small models comprise a square or round frames that can be attached to a roof or installed as standalone units. Most solar heaters made of rigid material come with adjustable legs that permit users to position the unit to soak up as much sun as they can.

Solar pool heaters that are large comprise of panels that have to be attached to structures that are usually erected rack directly on top of the floor or the roof of a house. The majority of large solar pool heaters require that the owner purchase racks and installation kits in separate purchases, which makes the total cost more expensive.

Thermo-Efficacy and Temperature

The ability of a solar pool heaters to increase the temperature of the pool water is contingent on several variables, such as the surface area of the heater and the number of minutes of sun direct that the heater is exposed to regularly. In the event of a cloudy day, the solar heater won't affect the temperature of water in a pool.

Typically, the capacity of a heater to alter the temperatures of a pool water is determined by the dimensions of its surface. If properly sized the solar water heater can raise the temperature of a pool to 10 degrees in many days.

Materials and Durability

If you're asking, “How much is a pool solar heater?” It's crucial to consider the long-term durability of the materials and the design. Most solar heaters comprise black polypropylene. It excels at taking in the solar heat. Polypropylene is also flexible and light, making it much easier for DIYers to install it on an overhang than a solid solar panel.

Although polypropylene is not abrasive to pool water, it can be damaged by UV radiation. This is why high-quality solar heaters are made of polypropylene coated with a stabilizer that shields it from harmful UV rays. This layer of protection gives it a typical lifespan of between 15 and 20 years.

Smaller models that be placed on the ground are made of polypropylene tubing or plastic wrapped in a weatherproof container with a frame made of metal and a translucent or glass cover.

Solar pool heaters have been regularly cleaned to keep debris from accumulating over or around them. It's also crucial to empty the solar heater before the temperatures begin to drop in winter or fall to avoid damaging the pipes.
