Heating.
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

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
