Rinnai’s Infinity Plus range of solar water-heating solutions includes solar storage vessels and both flat-plate and evacuated- tube (pictured) solar collectors. Both types of collector work best when facing due south. However, evacuated-tube collectors will outperform flat plate when it is only possible for them to face east or west.

In summer, flat-plate collectors have a performance close to evacuated tubes when sited correctly. Evacuated tubes have better overall results in the early and late seasons and in overcast conditions. Flat-plate collectors are more robust and more easily integrated into a roof.

Infinity water heaters can accept high incoming water temperatures from, for example, a solar store. Modulation range is from 58 kW down to 2.4 kW.
