1. Suitable for both flat roof and slope roof

2. Employing sliding way for the frame, much easier for installation, especially suitable for European-styled houses

3. High efficiency: >55% and >40% in winter

4. Still works as normal as before even one vacuum tube destroys

5. Hailstone resistance: 25mm

6. Higher efficiency, stable performance, beautiful design



The whole system has excellent outlook, easily installation, high performance etc. It is becoming the one of professional products accepted by worldwide users in different field, like domestic hot water supply, big project like: central heating, house heating, hotel, hospital, school, super market/mall, and industry project or any other hot water using area. We will develop and make design according to customer's requirements.Solar heat pipe collector can supply from 15 tubes, 20 tubes, 25 tubes, 30 tubes per unit, and tank/cylinder capacity from 150L, 200L, 250L, 300L......2ton or more. Of course, we can make other model as your requested, like 12 tubes, 18 tubes, 24 tubes etc.
