Due to customization options, DS Boilers are not a stocked item. They are built to order and will require a 3-8 week lead time from date of order.
DS has over 30 years of experience in designing and engineering boilers. This hydronic system is a whole heating solution that 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. DS 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, the Aqua-Gem boiler easily maintains water temperature and features a large capacity ash pan. All DS boilers are designed with the best-cast iron grate system and built to last.
