The Best Active Solar Water Heating Systems

Posted by outside_voices on Tuesday, 16 February, 2010

There is perhaps no more economical as well as cost beneficial way to make use of renewable technology than by opting to use an active solar water heating system. Such a system will help in significantly bringing down the need to use traditional water heating systems and does so by about as much as two-thirds. In addition, an active solar water heating system will cut your electricity or fossil fuel bills and more importantly will improve the environment by cutting out pollution.

Electric Pumps, And Collectors

An active solar water heating system relies mainly on electric pumps that along with collectors that circulate water or other fluids and together these two components round off the main components of the system. As a matter of fact, there are also three distinct types of active solar water heating systems that are worth knowing more about.

The first kind of active sun-powered water heating system is the one known as direct-circulation system in which a pump circulates pressurised as well as drinkable water straight thru collectors. Such types of systems are well matched for use in areas where there’s not much or no freezing and where the water isn’t hard or perhaps acidic. such active solar water-heating systems haven’t been given approval by Solar Rating & Certification Firm , particularly in case such systems also employ protection from recirculation freeze which needs use of electricity to make sure that the protection is effective.

The other sort of active solar water heating system is the indirect circulation systems which are further categorized as antifreeze and drain back systems. The antifreeze indirect active solar heating system uses a mix of glycol and water while the drain back indirect active solar water-heating system gets use out of pumps to circulate water through collectors and which also suggests that water in collectors loop drains into reservoir tanks whenever the pump stops working.

The drainback indirect active solar water heating system is best suited in places where the climate is especially cold though such a system does also require to be installed very carefully to ensure that the piping is made to slope in a downward direction at all times so as to allow the water to completely drain out from the pipes. This however is not all that easily achievable.

An active solar heating system is a commonsense answer to keeping a home or building warm and in reality, usually such systems are used to provide between 40 and 80 % of heating wishes of a home. Systems that provide less than 40 % of the heating necessities are not cheap and so must be evaded as much as feasible.

Wind Energy Turbines – An Overview

Posted by outside_voices on Tuesday, 29 December, 2009

Solar heating systems have now become a more usable option for more people today as the technology has advanced and the costs have come down. It requires a lot of energy to heat the water that comes into the home, particularly for bigger homes. The hot water is utilized for such a spread of purposes , for example washing garments, showering, washing dishes and other activities. This could place a large burden on the family thru gas or electrical bills, and having a solar hot water heating unit can help with this cost in the future.

Choices

If an individual lives in a colder climate where there is a big freeze for several months of the winter, then there are not as many options in solar hot water heating units since the water can tend to freeze in the pipes, not getting enough heat from the sun.  For those that live in milder climates, having a solar hot water heater can be an excellent choice, conserving cost and also the environment through the use of the unit.  In addition, the individual can also have solar roofing panels installed which can help with the energy costs for the rest of the home, such as electricity to power lights and other pieces of equipment.  In some cases where the home gets a lot of sunlight throughout the year and has a south facing section of roof, the individuals may reduce their electric bill to nothing, or even get a check from the electric company as they sell the extra energy their solar panels provide.

There are two general types of solar hot water heating units on the market and each type has two styles of units in it.  The first is the active solar hot water heating unit, which has a type of pump in it so that the water is circulated through the solar panel to better heat the water.  There are direct circulation systems that circulate the water in the home through the collection system and there are the indirect circulation systems which circulate heat transfer fluid through the collection system and also a heat exchanger.  This second type is usually used in freezing climates so that the water does not freeze during the circulation process.  The other type of solar hot water heating system is the passive system which has integral collector storage systems and thermosyphon systems.  Neither of these systems is usually used in climates where there are freezing temperatures for most of the winter months since the water will freeze in the system.
