Why Choose Solar Water Heating with EnviroCare?


Proven Technology:

Solar water heating (SWH) or solar hot water (SHW) systems use renewable energy technologies that have been tried and tested for years. This technology effectively harnesses the power of the sun to provide hot water for your home.

Abundant Sunshine in Spain:

With Spain enjoying many hours of sunshine throughout the year, solar domestic hot water is an excellent free source of hot water. It’s no wonder that solar water heating is widely used and appreciated in Spain.


Types of Solar Water Heating Systems:

There are two main types of solar water heating systems we install:

Gravity Solar Water Heating System: In this system, the storage tank is mounted horizontally above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermosiphon flow.

Pump-Circulated System: Here, the storage tank is ground- or floormounted below the level of the collectors. A circulating pump moves water or heat transfer fluid between the tank and the collectors.


Boosting Performance in Winter:

While Solar Water Heating systems in Spain deliver hot water for most of the year, there might be times in winter when solar heat gain isn’t enough. In such cases, a gas or electric booster can be used to heat the water, ensuring you have hot water year-round.


Spain’s Solar Initiative:

Spain has been a pioneer in promoting solar energy. In 2005, it became the first country to require photovoltaic electricity generation in new buildings. Following that, in 2006, Spain mandated the installation of solar water heating systems in all new builds.

Factors to Consider:

When assessing which type of solar system is best for your property, we consider various factors:


  • Water temperature and volume requirements.
  • Changes in ambient temperature and solar radiation throughout the seasons.
  • Day-night temperature fluctuations.
  • Number of property inhabitants and bathrooms.
  • The minimum requirements of a solar hot water system are often determined by winter’s demands when the system’s output is typically lowest. The system’s maximum output is designed to prevent the water from overheating.


Ideal Climate for Solar Water Heating:

Spain’s year-round ideal climate makes it perfect for fully benefiting from a solar domestic hot water system.
