Buying Guide For Solar Heating Floats/Covers for Pools

Type/material Quality: Solar floats feature sheets of heavy-duty and rugged vinyl. This is because it allows it to effectively trap energy from the sun, and an insulating layer ensures that the trapped energy is retained even at night. However, overexposure to direct sunlight often leaves the floats broken and chipped. To take care of this, look for products with durable vinyl layers with UV-resistant properties.

Size of your pool: A simple knowledge of arithmetic should get you through selecting the right float size for your pool. As a rule of thumb, purchase many floats if your pool is large and small quantities of floats if you have a small pool. This means that the size of your pool determines how much heating floats that you purchase. 

Thickness of pool cover: For pool covers, ticker always means better heat retention power. This said thick covers retain heat better than light ones. Also, they stay in place during a storm. However, they are most expensive than thin ones and can be difficult to roll up.

Ring Design and Decorations: Like the ocean, the best solar heating floats for pools often come with a blue layer for easy sunlight absorption. This said they come in different sizes. Shapes, and aesthetic designs. Therefore, based on your aesthetic taste, choose a float that meets your preference and style. 

Types of Solar pool covers: For better decision making, there are different types of solar pool covers. This includes bubble pool covers, solar sun rings, and liquid solar covers. The bubble pool covers feature thermal bubbles that are responsible for trapping heat in the pool. They also supply up to 15 0 F to the pool and reduce up to 95% evaporation. The solar sun rings, on the other hand, contain a UV-resistant vinyl layer to reduce evaporation and help heat retention. Lastly, the liquid solar covers reduce up to 40% evaporation. Like most liquid, they are used on the pool surface to form an invisible cover.

Benefits: Solar pool covers increase heat retention by trapping energy from the sun. They also act as a barrier between water and air in your pool. This way, you enjoy seamless energy conversion without any physical input. Since the covers not only retain heat but keep it trapped, it reduces evaporation by up to 95%. Besides, if evaporation is taken care of, it ultimately reduces the amount of chemical needed and less cost of replenishing the chemicals.
