1. Introduction
RegulusRGMAT E W-iPWM Load Unit makes boiler installation quicker as it contains all components
needed for boiler circuit circulation and for boiler protection against low-temperature corrosion. It is
designed to be installed directly on return piping. The distance of pipe axis from a wall shall be at least
100 mm to enable insulation removal if needed.
This Load Unit is intended for hydronic fireplaces and solid-fuel boilers.
2. RGMAT E W-iPWM Load Unit Description
RGMAT E W-iPWM keeps the temperature in a hydraulic boiler circuit above the flue gas condensation
temperatures, which prevents so called low-temperature corrosion of the boiler combustion chamber.
This limits condensation and boiler tarring significantly, the efficiency of fuel combustion increases and
service life of the boiler is extended.
