DS Machine Coal and Wood Boiler: Aqua Gem Boiler #3200

  • $0.00

This hydronic system requires no electricity to heat water for floor heating, baseboard, freestanding radiators, heat pumps, or domestic water. It works well with new or existing oil or electric boilers. Our boilers circulate water in the front to prevent cracking. Each unit is pressure tested to 120 PSI and has a powerful heat exchanger for maximum efficiency. Constructed from 1/4" steel, this Aqua-Gem boiler easily maintains water temperature and features a large capacity ash pan. All boilers are designed with the best cast iron grate system and built to last.
