The VVH (Vapor Vacuum Heating) technology utilizes a well-known and widely successful heat transfer concept called the “Heat Pipe”. Since the 1960’s, Heat Pipe devices have demonstrated exceptional efficiency and reliability in
many applications ranging from spacecrafts to laptop CPUs.

However, due to high manufacturing cost and length limitations, Heat Pipe technology has not been implemented in buildings’ heating systems. With VVH, the limitations of Heat Pipe technology have been resolved, allowing it to be used
in the heating of any building with a variety of heat sources such as boilers, district heating, distributed power systems, and renewable (solar and geothermal) systems. Consequently, a VVHS would offer a much better alternative to traditional heating systems. No other modern heating system can offer such high levels of benefits of each of the following:

• Efficiency
• Health
• Comfort
• Safety
• Low installation cost
• Reliability (no moving parts)
• Space saving
• Minimal maintenance
• Electricity independence (if fueled by gas)
• No frozen pipe problems
• No damage from leaks
• Optional control for either each radiator or zone control, or a combination of both
• Broad operating temperature range

VVH can be utilized for new installations as well as retrofits. The retrofit of an obsolete steam heating into a VVH system is less expensive and a better alternative to converting to a hydronic system.
