One of the Most Efficient Type of Solar Hot Water Systems.
Roof mounted solar hot water (also referred to as a “close-coupled” or “thermosiphon” system) is widely regarded as one of the most efficient type of solar hot water systems.
Because the tank is above the collectors, the system works entirely on the thermosiphon principle (eg, the heat rises naturally into the tank).
While the ‘flat plate’ style of collector is slightly less efficient than the Apricus ‘evacuated tube’ system (see graph illustration above for a comparison between the two types), there are some big advantages in the roof mounted tank. This system is particularly suitable for off-grid installations (where the extra power usage of a solar circulating pump might be an issue), and also where you have limited space for a storage tank on the ground.
This also means your entire hot water service is on the roof, so you no longer have a bulky storage tank on the outside wall of the house. Rinnai roof mounted systems come with a long-life, stainless steel tank as standard, providing you with peace of mind for years to come.
