About Solar Water Heating

 

As solar thermal technology does not rely on sunlight but on solar radiation, it can work as efficiently in our climate to provide around 50-70% of annual domestic hot water requirements.

Using the sun as a renewable energy source helps the environment, leads to reduced energy bills and means less reliance on gas and electricity for water heating.

Oil and gas prices are going through the roof. Heating is becoming a luxury for all. Fossil fuels such as oil, gas and coal are growing ever scarcer. The CO2 burden on the atmosphere is leading to a climate disaster and air pollution is reaching a critical point.

Optimal solutions will make your heating costs melt away and provide all the hot water required between May and September. Our state of the art, reliable and maintenance free

technology is suitable for all types of property.

Even the most innovative technology is only as good at it performs in practice. That’s why, at Advanced Heating & Plumbing Plus, the utmost attention is paid to the reliability of solar heating systems in everyday use. They must be easy to assemble, low maintenance, easy to use and have a long useful life. This is the only way to convince customers that changing to environmentally friendly solar energy will be beneficial in the long-term.

Solar Water Heaters

 

Solar water heaters—also called solar domestic hot water systems—can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use—sunshine—is free.

How They Work

 

Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don’t.

Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.

Three types of solar collectors are used for residential applications:

Flat-plate collector

Glazed flat-plate collectors are insulated weatherproofed boxes that contain a dark absorber plate under one or more glass or plastic (polymer) covers. Unglazed flat-plate collectors—typically used for solar pool heating—have a dark absorber plate, made of metal or polymer, without a cover or enclosure.

Integral collector-storage systems

 

Also known as ICS or batch systems, they feature one or more black tanks or tubes in an insulated, glazed box. Cold water first passes through the solar collector, which preheats the water. The water then continues on to the conventional backup water heater, providing a reliable source of hot water. They should be installed only in mild-freeze climates because the outdoor pipes could freeze in severe, cold weather.

 

 

Evacuated-tube solar collectors

 

They feature parallel rows of transparent glass tubes. Each tube contains a glass outer tube and metal absorber tube attached to a fin. The fin’s coating absorbs solar energy but inhibits radiative heat loss.

Direct circulation systems

 

Pumps circulate household water through the collectors and into the home. They work well in climates where it rarely freezes.

Indirect circulation systems

 

Pumps circulate a non-freezing, heat-transfer fluid through the collectors and a heat exchanger. This heats the water that then flows into the home. They are popular in climates prone to freezing temperatures.

Passive solar water heating systems are typically less expensive than active systems, but they’re usually not as efficient. However, passive systems can be more reliable and may last longer. There are two basic types of passive systems:

Integral collector-storage passive systems

 

These work best in areas where temperatures rarely fall below freezing. They also work well in households with significant daytime and evening hot-water needs.

Thermosyphon systems

 

Water flows through the system when warm water rises as cooler water sinks. The collector must be installed below the storage tank so that warm water will rise into the tank. These systems are reliable, but contractors must pay careful attention to the roof design because of the heavy storage tank. They are usually more expensive than integral collector-storage passive systems.

Solar water heating systems almost always require a backup system for cloudy days and times of increased demand. Conventional storage water heaters usually provide backup and may already be part of the solar system package. A backup system may also be part of the solar collector, such as rooftop tanks with thermosyphon systems. Since an integral-collector storage system already stores hot water in addition to collecting solar heat, it may be packaged with a demand (tankless or instantaneous) water heater for backup.

Solar Water Heater

 

Before you purchase and install a solar water heating system, you want to do the following:

  • Consider the economics of a solar water heating system
  • Evaluate your site’s solar resource
  • Determine the correct system size
  • Determine the system’s energy efficiency
