Separate Pressurized Solar Water Heater
1. Jinyi separate pressurized solar water heater systemSolar Water HeaterSolar water heating also called solar domestic hot water systems, can be a to generate hot water for your home. They can be used in any climate, and the fuel they use sunshine is free.
2. How Solar Water Heater 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.
3. solar water heating system type:
1) There are two types of active solar water heating systems:
A: Direct circulation systems
Pumps circulate household water through the collectors and into the home. They work well in climates where it rarely freezes.
B: Indirect circulation systems
Pumps circulate a non-freezing, through the collectors and a . This heats the water that then flows into the home. They are popular in climates prone to freezing temperatures.
2) 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 systemsThese 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 systemsWater 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. 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 for backup.
4. Selecting a 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
Estimate and compare system costs
Investigate local codes, covenants, and regulations.
5. Installing and Maintaining the System
The proper installation of solar water heaters depends on many factors. These factors include solar resource, climate, local building code requirements, and safety issues; therefore, it's best to have a qualified, solar thermal systems contractor install your system.
After installation, properly maintaining your system will keep it running smoothly. Passive systems don't require much maintenance. For active systems, discuss the maintenance requirements with your system provider, and consult the system's owner's manual. Plumbing and other conventional water heating components require the same maintenance as conventional systems. Glazing may need to be cleaned in dry climates where rainwater doesn't provide a natural rinse.
6. Improving Energy Efficiency
After your water heater is properly installed and maintained, try some additional to help lower your water heating bills, especially if you require a back-up system. Some energy-saving devices and systems are more cost-effective to install with the water heater.
