The line of products comfort-tech RKR, is the program of condensing combination units made by Radiant. They are available in three sizes 24, 28 and 34
kW and are designed to optimise the well-being thus
to avoid un-necessary waste of energies. The aesthetics are appealing, the control panel is ergonomic and
features a white back-light and integrated functions.
These units are now heavily re-vamped, either inside
and outside, to combine our reliability to the electronics aimed to enhance our performances.
OUR WELL FAMOUS RELIABILITY is now even
improved, thanks to high-tech electronics, specifically
designed to keep under control all the functions, directly within the boiler and then get the best of our
performances.
USER FRIENDLY anyone’s well being can be easily
satisfied through the control panel and then avoid
useless wastes. Among the others, we would emphasize the H2O FAST function, which can be activated
from the end user and delivers hot water in a much
faster way.
BETTER EFFICIENCY new components, mostly
brass made, are fitted ex-factory to guarantee the
best possible reliability and long lasting performances, thus to reduce the possible number of interventions.

make it better the overall SAVINGS.
