from l to r: Arneson, DeNigris & Samsel

Case in point: William Frew, Owner/Vice President Sunshine Plumbing Heating Air received a no-heat call at Brian Todd’s rental home, an 825-sq.-ft. starter home in Brighton, Colo. Sunshine sent out some of its fastest rising stars: Under the brilliant guidance and watchful eye lead tech Lorenzo DeNigris, Frank Samsel, trained by the PHCC apprentice school in Pennsylvania, and Michael Arneson, who started as a young helper and has excelled in the trade, went to the Todd home to investigate.


The replaced boiler

When the three arrived at the residence they found the old, original boiler—located in a mechanical closet with no fresh air in the basement—was in disrepair and needed immediate attention, and replacement.

With the help of manufacturer’s rep HSI, Denver, Sunshine selected the Dunkirk DXL 125 cast iron boiler due to its durability and longevity. The hydronic installation includes a Taco 007 circulator, three Honeywell ¾ sweat zone valves (V4043) with a Taco 3-zone valve controller (TZV403) to separate the upstairs, downstairs and bedroom through copper fin baseboard heat. In addition, they opened up the room to allow fresh air and light.




The Dunkirk DXL 125 boiler

“There are three critical things to consider when selecting a boiler in our area. 1) Are there local manufacturer reps? 2) Can another plumber work on this, if needed? And 3) Are parts readily available? The answer is yes to all three. In fact, the Dunkirk cast iron boiler is one of the most popular boilers in the area,” says Frew.
