Evacuated Tube Panels
U Pipe Direct Flow Double Manifold System
Logical Energy are the sole distributors for the German certified pUre evacuated tube collectors manufactured to EN12975. Carefully selected for performance, asthetics, ease of installation and lack of required maintenance, these MCS approved collectors represent the best value per kW of any system on the market and outperform most other branded solar collectors.
Direct Flow is a very simple system that works in a similar fashion to a conventional flat plate collector but with the benefit of vacuum insulation. These collectors represent a giant leap forward in solar heating technology.
The U-Pipe collectors have the same copper tube as a traditional heat pipe collector, but it instead bends around on itself at the bottom of the glass tube and returns directly into the double manifold. This enables the heat transfer fluid to travel through the tube for direct gain from solar radiation. As this heat transfer fluid is heated, it is pumped around the collector tubes and eventually passes through the secondary coil in the hot water storage cylinder. The pUre U-Pipe Collectors require fewer tubes up on the roof than heat pipe to reach the same peak efficiency levels.
With the Renewable Heat Incentives now underway, there has never been a better time to invest in solar thermal technology and the substantial carbon reduction savings provided by the pUre series.

Heat Pipe Evacuated Tube Collector
Our Heat Pipe Collector uses the same highly efficient double wall vacuum tube and multi coated absorber as the pUre collector; giving the Heat Pipe Collector the highest rating in its class. Each glass tube is fitted with an aluminum contact fin which serves as the heat transfer contact and also holds the heat pipe against the inner wall of the glass tube. The heat pipe is evacuated and filled with a small amount of heat transfer liquid; which as well as being rated to a very high temperature is also frost proof.
Heat is transferred from the heat pipe evaporator to the condenser through to the manifold. The manifold heat exchanger contains a copper main pipe which is in contact with each heat pipe allowing the heat generated to pass to the solar loop. The manifold is insulated with polyurethane foam and encased with an UV stabilised aluminum profile.
