solar hot water

Why pay to heat water when sunlight is such an abundant resource? Efficient, well designed and installed solar hot water systems provide an almost year round, environmentally friendly and practical alternative to electric and gas hot water systems.

Do you rent out your villa? Is the house a holiday home? Do you manage a hotel? In these situations, hot water for sanitary, clothes and dish washing is one of the greater expenditures. Furthermore, water heating is often restricted by the supply of gas bottles or an unreliable electrical supply.

Say goodbye to those bills, gas bottles, sporadic electricity and develop your own power plant!

how does it work?

Water flows from the bottom of the stainless steel tank, where water is coolest, to the collector/panel where it is heated. The heated water then returns to the top of storage cylinder, where water is hottest, and it is available for use. This process requires no management, and after installation the hot water system operates completely hands free.

Solar panels come in 2 distinct types, evacuated tubes, which are more suited to households which experience a large usage of hot water and flatplates, which are best suited to smaller households where demand is not so high, particularly in winter.

After water is heated by the panel, it can be stored in a cylinder next to the panel in what is known as a compact system. Alternatively, water may be stored in the house in a separate storage tank. This allows greater capacity, while placing the tank out of the sight and easier to maintain in what is called a pumped system. As the name suggests a small pump exchanges water between tank and panel. This pump is thermostatically controlled by a controller. Both systems provide mains pressure hot water.

Solar in Spain provide compact evacuated tube panels, compact flat plate and pumped evacuated tube panels.
