Calculate savings for your equipment

Heat loss depends on the exposed area, surface temperature, air movement and operating hours. The measured temperatures above describe this installation; they are not an annual energy-saving measurement.

Use the Boilers & utilities calculators to enter your equipment data and fuel price. The detailed calculation includes convection and radiation and compares heat loss before and after insulation.

Why boiler doors are usually left bare

These surfaces can be insulated, but the insulation must allow routine access and refitting. Removable modules are designed for that maintenance cycle.

Conventional insulation jackets

  • Held on with straps, wire or velcro
  • Those fasteners pull the fabric into creases and dents
  • Removal and refitting depend on the fastener layout and available access
  • The insulation must be refitted after maintenance

Inzonex modular insulation

  • Snap-button fasteners + functional zipper + structural inserts
  • Sections made to the equipment dimensions
  • Snap buttons open by hand for removal and refitting
  • Insulation core replaced separately through the zipped shell

What we insulated

The installation includes removable sections for the following equipment, with openings retained for operation and inspection.

Front & rear boiler doorsRemovable sections provide access for servicing and door opening.
EconomizerRemovable insulation around the exposed casing and service points.
Feed-water & CR pumpsPump bodies insulated; motors remain uncovered.
Safety / pressure-relief valvesCovered up to the spring, access preserved.
Manholes & hatchesSeparate sections can be removed when a hatch needs to open.
Valves & flangesFitted around connections, with controls accessible.
Water-level columnsBodies insulated, sight section left open both sides.
Burner mounting flangeRemovable insulation around the mounting flange.
