Solar Central Heating

Preconditions for solar central heating in Spain:

• relatively well insulated buildings (at least double glazing)
• a low-temperature heating would be good, such as under floor heating, aluminum radiators or skirting board heating (e.g. Climaboard)
• the size of the solar collector array will be bigger (some 8 - 16 m²)
• the solar buffer tank will be bigger, too (> 800 l)

In the Comunidad de Valencia, you will be getting grants for solar central heating that is usually accompanied with solar domestic hot water (ACS = agua caliente sanitaria).

For that reason, experiences have shown that the so-called 2-tank-solution offers a maximum of comfort to the client. The smaller ACS tank of some 200 - 300 liters will be heated first until it has reached a certain temperature. Then, the solar circuit switches to the bigger central heating tank of some 800 - 1.000 liters. This set of tanks guarantees that you will always be having hot water in order to take a shower the next morning.

All our clients on Costa Blanca - regardless if their "old" backup heating system is gas or oil - found out that they will save some 60 - 70 % of their original heating costs. If, for instance, a househood needed originally 16 gas bottles (35 kg each), they will afterwards only require some 4 gas bottles per year!

However, one of the most important reasons - besides the financial aspect - to decide in favour of an installation for solar central heating is comfort! During winter time - and regardless if the property owners are staying in the house or visiting their families over Christmas and New Year - the house will heated by the sun without generating any costs. Not only will the house be having a very comfortable warmth, it will also reduce humidity within the building!
