Mobile Hot Water Boiler Rentals

Clean, potable hot water, even in remote locations.

Using our expertise in creating steam boilers, WARE has constructed its own fleet of reliable, easily portable, powerful, space-efficient hot water boilers that are ideal for a wide range of process and domestic heating situations.


Mobile hot water boilers are best suited to smaller applications that don’t require a lot of working steam, but do need a lot of hot water on demand. WARE’s rental boiler fleet is standing by for:

  • Assisted Living Facilities
  • Hotels
  • Detention Centers
  • Hospitals
  • Construction sites
  • Temporary housing
