THE EVOLUTION OF THE HEAT EXCHANGER

Since 1959, Radiant has been on the cutting edge of heat exchanger design. Designing and manufacturing from the ground up, Radiant has built their own heat exchangers in house from day 1. With a constant focus on effi ciency and reliability, the heat exchanger has evolved into the heart found in each Radiant product. The newly introduced Flowtech heat exchanger is made from T316 stainless steel, with a tube diameter of 28mm, which makes for higher efficiency numbers, 97 EF to the 0.954 UEF, less head loss, and easier maintenance. With 57 years of unparalleled experience and know how… the Flowtech heat changer comes with a 10 year, no questions asked warranty.

Combi-Tech

OUTSTANDING THERMAL EFFICIENCY

RADIANT boilers offer a remarkably high 97% thermal efficiency. This means that $0.97 out of every fuel dollar goes into heating the water, dramatically reducing the operating cost of the equipment. RADIANT achieves this efficiency through the combination of an advanced fan assisted combustion system and highly durable 316 stainless steel exchanger. A time tested proven combination.

The heat energy from the combustion process is transferred to the water as it passes through the 316 stainless steel heat exchanger. The sealed combustion design eliminates external heat losses, this means that the energy dollars heat the water, not the mechanical room. It also ensures that the boiler jacket stays cooler, providing greater safety, and requires less clearance from combustible walls.
