Solar Hot Water

Free hot water from the sun!

solar2EnviroCare SL have been fitting Solar hot water systems in Spain since 1996. Their engineers are technically competent to undertake the installation and to give helpful advice on the size of the tank required for each individual property.

Solar water heating (SWH) or solar hot water (SHW) systems are effective by using the latest renewable energy technologies that have been well established for many years.

Solar domestic hot water is widely used in Spain; after all with many hours of sunshine during the year, it is a free source of hot water.

In a gravity Solar Water Heating system the storage tank is horizontally mounted immediately above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermosiphon flow. In a "pump-circulated" system the storage tank is ground- or floor-mounted and is below the level of the collectors; a circulating pump moves water or heat transfer fluid between the tank and the collectors.

solar1SWH systems installed in Spain deliver hot water for just about all of the year. However, in winter there occasionally may not be sufficient solar heat gain to deliver enough hot water. In this case a gas or electric booster are used to heat the water.

In 2005, Spain became the first country in the world to require the installation of photovoltaic electricity generation in new buildings, and the second (after Israel) to require the installation in all new builds of solar water heating systems in 2006.

These are some of the factors we take into consideration when assessing which type of solar system is necessary:

  • The temperature and amount of the water required from the system
  • Changes in ambient temperature and solar radiation between summer and winter
  • The changes in ambient temperature during the day-night cycle
  • The number of inhabitants of the property
  • The number of bathrooms in the property

The minimum requirements of a solar hot water system are typically determined by the amount or temperature of hot water required during winter, when a solar water heating system's output and incoming water temperature are typically at their lowest. The maximum output of the system is determined by the need to prevent the water in the system from becoming too hot.

Spain has an ideal climate year round to benefit fully from running the domestic hot water via a solar system.

The question that has to be asked is: "Why wouldn't you have a Solar Hot Water system?"
