The World’s First Hybrid Condensing Water Heater!

The Quattro has arrived! Like the Aqua², the heart of every Quattro Hybrid Condensing Water Heater is the revolutionary Flow-Tech® Heat Exchanger typically found in heating boilers. For the first time ever Radiant has taken boiler technology, applied it to the tankless water heater and added an integrated 40 gallon storage tank! The result is an appliance that offers traditional tank-style delivery, produces huge amounts of hot water , can be vented up to 100’ with 2” PVC, and has a Thermal Efficiency rating of 97% all built in to one tidy Ferrari Red cabinet. Gone are the days of messy wires, freestanding tank clutter, hot water delivery delays, temperature fluctuations, and nuisance service calls. This user and service friendly design performs even better than it looks.

The Aqua² was a great trick, and WE DID IT. The Quattro by Radiant takes water heating to a whole new level!

Don’t settle.

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.

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. RADA 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.
