This new micro-boiler is the ideal replacement
for traditional boilers and tank-type heaters and is the enabling technology for use
with active renewable energy systems such as solar and
geothermal systems.
Features
• ANSI/UL 834 Approval Listing for Space Heating Systems• Works with tubing and manifold systems• No minimum � ow activation required• Built-in DSM Utility Integration option• Compatible with Home Energy Management Systems• Heats � uid mixtures including ethylene glycol (antifreeze)• No moving parts• Very small & compact• Light weight modular construction• No restriction to � ow
• Standard 3/4 inch plumbing connections• Microprocessor digital control• Power sharing & variable power control technology• Continuous venting• Heats continuously only when needed, no storage• Self-diagnostics• Redundant safety devices• High performance polymer nylon chamber material• Built-in Leak detector and alarm• Rust & corrosion resistant
