Five million- (FBN5000) and 4 million-Btuh (FBN4000) units have been added to the Crest® condensing boilers. The line also has been expanded to include a dual-fuel gas train. Additional product enhancements include lower-firing input-derate numbers in high-altitude applications.
In the case of one Pennsylvania couple, haste to move on a “move-in condition” bi-level turned into a costly mistake. After dismissing the idea of a home inspection, the buyers quickly found themselves “throwing money into a bonfire.”
The FS5H QuickTrap® is designed for drainage of superheated or high-pressure steam mains, equipment, and turbines up to 650 psig and 800ºF. The FreeFloat® design allows for rapid and smooth removal of condensate, and the unique three-point seating ensures a steamtight seal, even under no-load conditions.
The NeoTherm® LC condensing boiler is a fully packaged, 1 million- or 1.7 million-Btu, space-saving hydronic unit that offers 94 percent thermal efficiency. It is a direct vent, sealed-combustion boiler or volume water heater that modulates with a 10-to-1 turndown.
The Gruvlok® KNX Series hydronic hook-up kits integrate the typical 54 components required to connect piping to hydronic heating or chiller system equipment into a pre-engineered, pre-assembled, and pre-tested kit of only four components, saving up to 80 percent on labor compared to traditional connection methods.
Older cities are loaded with boiler rooms full of steam-heating boilers, and lots of people — knuckleheads included — have had decades to mess with what the “dead men” once lovingly installed. So, here’s a short list of things to look for when you’re troubleshooting one of those old systems, starting in the boiler room.
The TriMax Control helps the Esteem 399 wall-hung condensing boilers deliver 96 percent efficiency for improved system operation and reduce energy consumption in a variety of commercial applications requiring 16,000-399,000 Btuh. The control’s 60-second setup simplifies boiler installation.
Microprocessor-based, the Fuel-Mizer™ outdoor reset switching relay control is designed to regulate the supply water temperature of a single boiler, based on the outdoor temperature. With reduced supply water temperatures, substantial energy savings are achieved, the company said.
So there’s this steam unit heater that won’t put out what it’s supposed to put out. It’s wimpy. The guy with the problem is telling me about it and he’s gesturing like he’s swatting bees. What is a contractor to do?
The new residential boiler efficiency standards just went into effect in September, with gas-fired hot water boilers now having to be a minimum of 82 percent AFUE. Many in the industry note that sales of higher efficiency boilers have been trending up, so homeowners are already expressing interest in better efficiency.
