5 Types Of Solar Water Heater in Florida

It is estimated there are currently over one million domestic and 200,000 commercial solar water heaters installed within the United States. Though there are different types of solar water heating systems, their basic technology is quite simple. It begins with sunlight striking and heating an absorber area within the solar collector or storage tank. Solar heaters are typically roof-mounted and can supply 80% of the required hot water for your home. The portable will flow via the tubes attached to the absorber surface. The heat is collected from it. Systems using a different heat-transfer loop have a heat exchanger which will heat up the potable water. This heated water is then stored separately in a preheat or conventional water tank until required. If the water requires additional heating, fossil-fuel energy or electricity can be applied.

If you’re shopping for a solar water heater Florida, learn the different types that are out there. These include:

#1 Thermosiphon Systems

This system heats an antifreeze fluid called glycol. This fluid will rise via natural convection from the collectors to the storage unit, which is typically placed on a higher level. Pumps are not required in this system. Fluid movement and heat transfer increases as the temperature rises. Thermosiphon systems work best in areas with large amounts of solar radiation.

#2 Direct Circulation Systems

In this system, water is pumped from the storage tank to the collectors during sunny periods. Protection from freezing is obtained by recirculating the hot water from the tank or flushing out the collectors. Since the recirculation system requires increased energy use while the flushing component reduces hours of operation, this type of solar water heater Florida is best used in areas that do not receive freezing temperatures.

#3 Drain-Down Systems

This is an indirect heating system. Untreated/treated water is dispersed via a closed loop. The heat is transmitted across a heat exchanger. If solar heat is not available, the collector fluid drains by gravity to prevent freezing.

#4 Indirect Water-Heating Systems

Freeze-protected fluid is transmitted via a closed loop. Heat is added to the potable water using a heat exchanger. Substances such as water-propylene glycol and water-ethylene glycol are used for freeze protection. This system has an 80-90% efficiency rate.

#5 Air Systems

This is an indirect system of water heating. Collectors will heat up the air and move it to an air-to-water heat exchanger using a fan. This water is then used for domestic purposes. The efficiency of a heat exchanger in air systems lies within the 50% range. Thermosiphon, pump-activated and direct circulation solar water heaters require higher maintenance. A majority of the solar water heaters in the United States are indirect air/water systems.

Everything You Need To Know About Solar Water Heaters Florida

Solar Water heaters Florida are often called solar domestic hot water systems. This is a cost-effective method of generating hot water for your domestic needs. In addition, they may be used in any weather or climate! What fuel source do they rely upon? Sunshine-and it’s free!

Types of Solar Water Heating Systems

In a solar water system, there is a solar collector and a storage tank. This forms one of two types of systems: an active one with controls and circulating pumps or a passive form.

Active Systems

There are two types of active solar water heaters:

Direct Circulation Systems: The pumps circulate water via the collectors into the house. They operate in just about any climate where freezing is not a concern.

Indirect Circulation Systems: The pumps circulate a heat-transfer fluid via the collectors and the heat exchanger. The water heats up and flows into the house. This type of system is commonly used in areas with freezing temperatures.
Passive Systems

This type of system is less expensive than an active one but not as efficient. They are however more reliable and durable. The two types of passive system solar water heaters are:

Integral collector storage: These are best used in areas that do not experience below-freezing temperatures as well as in homes that have significant day and evening hot water requirements.

Thermosyphon systems: Water begins to flow when the warm water rises and the cold water sinks. The collector is installed below the tank enabling warm water to rise into it. Although these systems are very reliable, attention must be paid during installation and particularly to the roof design as these tanks are quite heavy. Thermosyphon systems are also more expensive than integral collectors.

Types of Storage Tanks and Solar Collectors

Solar water heaters require an insulated storage tank, an inlet and an outlet which connects to and away from the collector. In a two-tank system, the water is preheated by the solar water heater before entering the conventional heater. In a one-tank system, a backup heater is placed within the solar storage.

In residential applications, three types of solar collectors are utilized:

Flat Plate Collector: These are glazed, insulated and weatherproofed boxes which contain an absorber plate under a glass/plastic cover.

Integral Collector Storage: Also called batch systems feature one or more black tubes or tanks in a glazed box. The cold water will pass through the solar collector which will preheat the water. Then it continues to the backup water heater for a reliable hot water source. These may only be installed in mild freezing climates because the outdoor pipes may freeze in harsh cold conditions.

Evacuated Tube Solar Collectors: These feature parallel rows of glass tubes. Within each tube is a metal absorber tube which is attached to a fin. The coating on the fin absorbs solar energy and inhibits heat loss. This type of collector is often used in commercial applications.

Before purchasing any type of solar water heaters Florida, it pays to heed to study and understand the different types of systems out there. Getting in touch with a solar energy company like PS Solar Systems can greatly help in this matter

Solar Water Heaters – What They Are And How They Operate

Solar water heaters are a cost effective method of generating hot water for your home. They are suitable for any climate and the only fuel they rely on is sunshine!

Solar collectors and storage tanks are important components in a solar water heater. In a two-tank system, water is preheated with solar energy before entering a conventional heater. In a single tank system, the solar storage and back-up heater are both combined in a single tank. Solar collectors and storage tanks work together to produce heated water for residential use.

Solar-water-heater

There are two types of solar water heaters: passive and active. The latter relies on circulating controls and pumps, while the former one does not.

Passive Solar Water Heaters

This type of solar heater is more affordable than active types, however they’re not as efficient either. There are two type of passive solar water heaters:

Integral Collector Storage

This type is most useful in locations where temperatures rarely dip below zero. They’re also useful in households that require significant amounts of daytime and night time hot water.

Thermosyphon Systems

These are more expensive than integral collector storage systems. Although very reliable, the storage tank for the water is quite heavy. In this system, the water flows and rises as it warms. As a result, the collector is installed underneath the storage tank.

Active Solar Water Heaters

There are two types:

Direct Circulation Systems

In this type of system, water circulates through the home via pumps and collectors. This system is ideal for locations where temperatures do not fall below freezing.

Indirect Circulation Systems

A heat transfer fluid is circulated via pumps, collectors and heat exchanger. This will heat up the water before it flows through the home. This type of system is ideal for areas that receive freezing temperatures.

If you are searching for energy efficient ways to obtain hot water for your home, consider investing in solar water heaters. Not only will you enjoy the savings on your next energy bill but you will also be playing your part for the environment.
