Solar Water Heating Systems For Homes: How Do They Work?

Thinking of adopting green technology in your home? Consider solar water heating systems for homes! This technology enables you to harness the power of the sun and use it to heat your water. Why is it becoming a popular choice amongst homeowners? Apart from its ability to heat water without increasing the carbon footprint, solar water heaters are efficient, guaranteed to reduce your monthly utility bill.

The following is a brief explanation about solar water heating systems for homes and how they operate:

What is a solar water heater?

This is a device that captures sunlight and heats the water in the pipes which can be used for domestic purposes, i.e. bathing, washing, etc.
It has four main components which work together to produce heated water. These are:
1) Thermal Panel or solar collector: This is installed on the roof. It gathers the sun’s rays on its flat surface.
2) Tank: This is where hot water is stored.
3) Circulating Pump: This accessory transports solar energy gathered from the collectors and transfers it to the tank.
4) Thermal Regulator: This device behaves much like a thermostat and regulates the heat of the system.

How do solar water heating systems for homes work?

The solar collectors on the roof absorb the sun’s light. The panels covert this into heat and pass it onto the water tank via a circulating pump. The thermal regulator triggers this exchange as soon as the temperature of the collector becomes hotter than the water within the tank. This inhibits the circulating pumps from using up too much energy. It also stops overheating.

What is the best way to fit collectors for maximum efficiency?

The collectors are most efficient during the midday in the summer months, pending the sky is cloudless and there is south-facing orientation. Collectors work fairly well in other seasons too, even when they’re facing east or west. For maximum efficiency, a 35 degree gradient towards the horizon is best.

In cases where there is insufficient sunlight, you may have to invest in a back-up system. This will bring the temperature of the water up without emitting carbon dioxide into the atmosphere.

Why opt for a solar water heating system?

With a solar water heater, you have an unlimited supply of sunlight to heat your water. It can provide substantial savings throughout the year. For example, a sun shining on a 1m² roof can replace 100 litres of heating oil and 100 m³ of natural gas. You can use solar energy for up to 70% of your domestic requirements such as running the dishwasher or washing machine, bathing, etc.

An investment in a solar water heating systems for homes will provide a lifetime of savings. To learn more about how this technology works, please contact PS Solar System.

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.

solar-water-heatere

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

Are Floridians Benefited By Solar Water Heater Panels?

Harnessing Solar Energy has become the need of the hour, as the non-renewable energy obtained from fossil fuels is exhausting very fast.Solar energy, being renewable is the solution that we need to get serious about. It should be incorporated in our lifestyle to give us the cheaper and more effective alternative. Sun’s abundant energy, when harvested, to use where we consume maximum electricity, can save our environment and lighten the load on our pockets.

We all need water heaters in homes as well as for commercial purposes. Electricity’s consumption worries us as it is not only expensive, it puts pressure on already diminishing non-renewable resources. Solar water Heaters bring to us the desired results from a resource which would not dry up on use and is energy efficient. Solar Water Heater Panels convert sunlight into heat energy by collecting the heat of the sun and storing it into water tank.The solar water heater panels are also called ‘Solar Collectors’ which are installed sun-facing. Solar water heaters are active and passive. They may use water only or water and working fluid. They are heated directly or via light- concentrating mirrors.

solar-panel

Flat – Plate Collectors for Solar water heating were used in Florida in 1920. They gained popularity in Florida as it receives 85% of the maximum solar resource available in the U.S. Thus it is an ideal place to use solar energy. The best system to heat water in Florida is ‘Active-Direct’ System. It is active as the fluid is directly pumped through the solar collector panel and it is direct because the fluid in collector is potable water. This collector panel is installed on the roof while the tank is below. System can also have Photovoltaic Panel which operates during power outages. Floridians have an extra benefit of installing the water heater system in the form of Federal Tax Credits. The Solar Water Heater provides hot water round the clock and can also store hot water for the next two days, catering for the bad weather.

The solar water heater panel have changed the course of life for the Floridians who have not only been able to control their electricity bills but also set an example of being the conscientious citizens.

Warming up: Solar Water Heating System

Solar energy has given us an abundant source of energy which is radiated in the form of heat and light. It can be harnessed with the help of technologies available such as Photovoltaics, solar heating or solar thermal energy. Since solar energy is available in high magnitude, it is an appealing source of electricity. Solar energy becomes even more attractive when we know that it is light on our pockets, renewable and pollution free, keeping the environment clean.

Conversion of sunlight into heat by using a solar thermal collector gives us a Solar Water Heating System. This collector heats the fluid and stores for future use. These systems use heat directly or via light-concentrating mirrors. The job of these mirrors is to concentrate sunlight to smaller collector. Solar water heating system design includes a simple glass-topped insulated box with a flat solar absorber made of sheet metal, attached to copper heat exchanger pipes. Heat is stored in water storage tanks. One must have a larger volume tank to store for the days without sunlight. The heat transfer fluid is a separate loop of fluid containing anti-freeze which delivers heat to the tank through a heat exchanger.

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.
