The 30L Compact Sigmar Marine water heater offers the following advantages, thanks to its innovative compact plastic casing and integrated brackets:

  • Occupy less space than an equivalent 30L boiler with separate fastening brackets, makes a great rv storage water heater.
  • Greater strength of plastic to corrosion, breakage or damage.
  • Greater electric insulation of plastic.
  • Better thermal insulation: more insulation material covers the upper part of water heater where heat dissipation is normally greater thanks to inside tank’s dis-axial position in respect of outside casing.
  • Plastic casing itself dissipates less heat than other materials.
  • Greater security: casing houses five sturdy fixing points (rather than the four of traditional separate side mountings/brackets).
  • Quicker and simpler installation: no separate side mountings/brackets to be dismantled/ remounted and integrated bracket’s five fixing points are easily accessible from the sides or above.
  • Safer installation: no sharp edges or burrs.
  • Heat exchangers in stainless steel AISI 316 ensure that waste engine heat is transformed into hot water.
