New Generation Evacuated Tubes

4uptubesThe evacuated tube system is the most popular type of solar system around the world. It has been around for 20 years and is still going strong. They are very cost effective and show excellent all year round performance. Evacuated tubes have revolutionised the solar industry, now heating water with solar energy is more than just a summer option.

Our solar tubes are a German technology with specifications and design to suit New Zealand conditions. They are very cost effective and show excellent all year round performance. The evacuation of the tube means low conductive and convective heat losses in times of low ambient temperatures and in wind. The tubes are evacuated like double glazed windows stopping heat loss out of the system. The water is always well insulated meaning you can gain solar energy in even below zero degree outside temperatures. More energy is used on heating water in the winter due to colder water temperatures and demands for hotter, longer showers. On cold frosty days when the sun is out they are working for you in heating your water and even pick up energy on cloudy days. The multifunctional controller automatically manages the temperatures on the roof and in your cylinders to give you comfort and peace of mind.
