Water walls are effective because they provide thermal mass and quicker heat exchange than concrete or masonry. According to Solar Today, water walls offer a 10 to 20 percent advantage over slightly larger masonry walls in moderate climates. In addition, energy savings in heating and cooling can be expected in the 70 to 90 percent range.
Water walls can be accented or invisible. In addition to water containers installed along a wall, the term can also apply to water containers in other passive building configurations. They can be incorporated in both new construction and existing buildings. Water walls are comfortable and cost effective in many a climate.
To boost performance even further, it is possible to combine a water wall with a strategically situated, insulating shell. With these two factors working together, some homes can maintain enough warmth to eliminate the need for a central back-up system.
Passive heating techniques in general are the most cost effective solar heating solutions. They require little to no maintenance, collecting and distributing heat through building design. Water walls can be used in conjunction with other passive techniques for superior results. These include using well-insulated windows, building sunrooms, and using a flat-plate solar water collector that doesn’t require pumps or fans.
