The XFyre™ and XTherm™ are commercial modulating, condensing boilers. The boilers are now CSA-Certified for polypropylene venting, when used with Centrotherm Innoflue venting components. Innoflue polypropylene venting is ULC-S636- and UL-1738-approved.

Sidearm water heaters were developed decades ago so that boilers could provide both space heating and domestic hot water. Is there an application they can be used for today?

Featuring low-H2O technology that enables the unit to heat quickly, the Linea Plus radiator can be used with low-temperature hydronic systems and renewable energy sources such as solar or geothermal. The discreet design allows for pipes and vents to be completely hidden behind the front panel and cabinet.

Radiant Heating Pipe X-Pert S5® is made with Dowlex™ 2344 polyethylene copolymer resin, which offers the traditional benefits of polyethylene resin along with excellent high-temperature resistance. The result is the next generation of radiant heating pipe, the company said.

NeoTherm® LC condensing boiler is a fully packaged, 1 million Btu, space-saving hydronic unit that offers 94 percent thermal efficiency. It is a direct vent, sealed combustion boiler that modulates with a 10 to 1 turndown. Zero clearance to combustibles with all piping and wiring from the back makes it a good choice for tight installations.

You probably realize some of your customers are just plain nuts, and others will take a chance on dying if it means they can save a few bucks on a repair or installation. Then there are customers who somehow turn nuts after you’ve done the work for them.

Intelligent controls built into the McDonnell & Miller RBT-3000 low-water cut-off and fuel economizer bring advanced microprocessor technology to virtually any existing boiler, automatically adjusting water temperature based on heat load and without the need for an outdoor sensor.

For use with the gas-fired boiler products — KC 1000, all Benchmark, and Modulex boilers — the AERCO Control System (ACS) provides the contractor with the key component to sell a complete combination system consisting of AERCO boilers, SmartPlate, and Buffer Tank, said the manufacturer.

A full line of high-efficiency condensing boilers is available. The Creek boiler models — Creek 4.0, Creek 6.0, Creek 8.1, and Creek 12.1 — can be used both as high-efficiency heating boilers as well as once-through hot-water heaters.

Interest in wood-fired hydronic heating systems continues to rise along with the price of conventional fuel. What kind of solutions are available and how do you handle them?
