Hydronics refers to the use of water as a heat transfer medium in heating and cooling systems. Heating water can be an energy intensive and expensive process. But not so when you utilise solar thermal energy provide free by the sun!

 Also known as solar thermal, solar hydronic technology can also take the concept of solar hot water a step further. Instead of just heating your water, it can also heat your home and be used in other commercial and industrial applications where large volumes of instant hot water are required.

How does solar hydronics work?

Given the energy intensive nature of heating water, solar hydronic systems can not only help reduce electricity related greenhouse gas emissions, but also save you money over the long term.

Briefly, here’s how a solar thermal system works:

Solar hydronic/thermal technology uses an evacuated tube collector system situated on a roof. Sun shining on the solar collectors heats a special fluid within the tubes. The fluid then pumps into heat exchange coils in a heavily insulated storage tank.

The heat exchange coils, strategically placed to ensure maximum efficiency, heat the water in the tank where it can be held for several days at suitable temperatures if weather conditions are unfavourable. Back up electric or gas booster systems can also ensure ongoing hot water.

The hot water can then circulate throughout a building on a continual basis, ensuring hot water is always immediately available. Without the long wait usually experienced with standard hot water systems.

The hot water can also pipe through radiators installed in strategic locations throughout a building to provide heating or through pipes situated under the floor, providing a gentle, radiant warmth. Bypass systems allow for this space heating aspect to switch off when temperature levels inside a building are optimum.It can also undergo adaptation for cooling purposes.

Given the superior heating process and advanced insulation, large volumes of hot water can be economically and cleanly generated and stored for days in low light conditions using a solar hydronics system.
