The Fire Tube KNIGHT® Wall Mount Boiler will make an appearance on an upcoming episode of PBS’s “Hometime.” Dean Johnson, host of the home improvement television show, and his crew recently documented the retrofit installation of a radiant floor heating system. At the request of the show, Lochinvar provided a KNIGHT Wall Mount unit with inputs of 199,000 Btu/hr (WH199) to provide heat for the radiant system and supply domestic hot water to an existing storage tank. The episode is scheduled to air for the first time on July 14, 2012, with a second airing tentatively set for September 8, 2012.
Since the featured project is a retrofit, the ENERGY STAR qualified KNIGHT is an ideal fit since it offers highly efficient operation. With a radiant heating application like this one, the Fire Tube KNIGHT Boiler offers up to 98.6 percent thermal efficiency as well as Low-NOx emissions and 5:1 turndown to keep fuel use to a minimum. In addition, KNIGHT’s advanced SMART SYSTEM control automatically adjusts the boiler water temperature as the outside temperature changes to further ensure the ultimate indoor comfort.
Lights, Camera, Installation
To kick-off the project, Dennis Hodgson with Team Mechanical and the “Hometime” crew first removed the home’s existing cast iron boiler and adjusted the venting system from metal to PVC in order to accommodate the installation of the new condensing boiler. The KNIGHT allows for multiple venting options, and the direct-vent sidewall option was selected as the best fit for this job.
Since the application required different temperatures on different levels of the home, as well as for the indirect water heater, the team added Lochinvar’s Multi-Temperature Loop Control accessory. This allows the system to operate at optimum efficiency, while distributing heat for multiple supply loops that require unique temperatures.
The installation was a success, and the home now boasts a highly efficient radiant heating system. In addition to its efficiency, the unique modulating design of the KNIGHT also allows for extremely quiet operation.
"We’re thrilled that the KNIGHT Wall Mount Boiler was chosen for this project on ‘Hometime,’” stated Stirling Boston, director of marketing for Lochinvar, LLC. “Dean and the crew are true home improvement experts – not only did they select the best boiler for this job, but they also demonstrated their expertise throughout the installation. We’re really looking forward to seeing the episode when it airs on Saturday, July 14th.”
