The form simplest and economic to take advantage of the solar energy is generating hot water sanitary.
The solar hot water (SHW) is the potable water of domestic use that we warmed up to have a greater comfort and better quality of life.
This hot water of clean form can be obtained and gratuitous of the nature, installing capturing thermal lots, that are the option more profitable than it offers the thermal solar energy. The installation is simple, the reasonable cost and it is amortized in just a short time.
A solar hot water installation is compound of a group of thermal solar collectors, a storage cell and a pump of circulation. The collectors can integrate themselves in the tile roof or be placed in a terrace without shade oriented towards the south.
The energy that is saved in the water heating is important, since with a simple installation it is obtained around 60% of the annual consumption.
In those centers with great hot water consumptions, like hotels, campings or sport facilities, is very advisable the installation of solar receivers. The power and economic saving is very great in these cases, being the very profitable installation.
If the hot water consumption is concentrated in summer obtains a still greater yield, since it is in summer when better the receivers work, being able to cover completely the demand very quickly and amortizing the investment.
A type of simple and economic installation exists that uses termosifónicos solar receivers and does without the other elements. These collectors take integrated a storage cell and work without pump. Of this form they do not consume electrical energy and they are not susceptible to failures. With this the cost of the installation diminishes considerably, being ideal for unifamiliares houses.
