Hot Water
LXW Series Models
Including multiple water tubes, Miura’s natural gas/propane hot water boiler is a low water content, water tube design, which provides full output within 5 minutes. Miura's Low NOx Hot-Water Boiler utilizes a flat shaped burner and rectangular shaped boiler vessel uniquely designed for the LXW.
  • Typically only one-third the footprint of conventional firetube boilers
  • Low NOx gas burner with “Quenched flame”
  • Up to 175HP per boiler


EXW Series Models
Miura's Gas/Oil hot-water boiler is a low water content, water tube design, which provides full output within 5 minutes.
  • Gas/Oil dual fuel burner
  • Up to 300 BHP per boiler
