Solar Air and Water Heating

Read Time:3 Minute, 27 Second

Solar heating systems are a great way to work with solar power in a cost-effective way. This can generate heated water, or even air, in any climate, using a free resource -sunshine! Home solar heating is really a not too difficult way to supplement your existing home heating, thus reducing your time use. This could decrease your electric bills. In doing this, the investment cost can soon be returned and you will be well on the way to a more energy smart and ecologically friendly household.

Solar Air Heating

A solar air home heating is an energetic system, as opposed to a passive one. Passive solar heating systems be determined by the southernmost windows to offer a degree of the heating load for the building, or also can rely solely on the structural elements such as for instance floors, walls and windows, to collect and distribute solar energy to offer heat in the wintertime and avoid it in the summer. Active systems, on the other hand, utilize solar panels, which collect solar energy and fans, which distribute the energy.

Solar air heaters draw upon the easy principal that heated air rises and cool air sinks. They have the ability to collect the cooler air at the bottom of an area, circulate it through the air heater, and then blow the warmed air back to the room. Solar air heaters are best utilized air and water heating if they’re installed where they have the ability to either blow or diffuse heated air into an area -preferably the one which is employed regularly throughout the day.

Solar air heaters utilize solar collectors to heat the air that passes through the unit. Solar heating panels may be installed on the windows, walls, or the roof – so long as there’s sunlight available. Also available are smaller “window unit” kind of solar air heaters, which can be installed under a window that receives full sun and south facing. These smaller units are direct-transfer systems, to ensure that heat is never stored. Accordingly, these types of units will be most advantageous if one is looking to use an air heater during times when sunlight is available to reduce electric costs.

How much money using a solar air heater can save depends on your home’s overall energy efficiency, and climate conditions. Naturally, these factors vary greatly from home to home and from destination for a place. These variables allow it to be difficult to say in any general terms simply how much may be saved. However, these systems prove most beneficial in areas that experience long winters with low temperatures and sunny skies. If your neighborhood does not fit these conditions, however, there’s still a beneficial way to take advantage of solar heating.

Solar air heating systems may be designed to also serve as a water heater throughout the warmer months. This of course will offset energy costs a lot more along with increase your return on investment costs. To achieve this kind of dual-purpose system, an air-to-water heat exchanger must be put into the system. Some systems also need a certain degree of plumbing.

Solar Water Heating

Unlike other new and upcoming solar technologies available today, solar water heating has actually been a quite well established and accepted system in most countries for most years. It is advised to really have a qualified solar thermal heating systems contractor recommend and use a solar water home heating because of the many factors that could determine the type of home heating and installation. Such factors include: climate, local building code requirements, safety concerns, and the solar resource that’ll be utilized.

For a solar water heater to work, a collector for the solar energy is generally positioned and installed on the roof for optimal sun exposure. The energy collected is then used to heat fluid (either water or, in some systems, another loop which contains anti-freeze and corrosion inhibitor) flowing through the system. Since solar water heating is generally a supplemental system, alternative energy source is generally linked to the device to offer back-up support to make sure heated water is definitely available.
