A relatively new concept to the boiler market, wall-hung boilers are the pinnacle of modern heating technology. They offer space and energy efficiency, while drastically reducing the difficulty of installation usually encountered with heavy, cumbersome, cast iron boilers of traditional design.
Dunkirk wall-hung boilers are highly adaptable and can be configured to meet any hot water heating system design; they work well in the three different design categories touched on in our heating page: 1) high-temperature, low-mass; 2) high-temperature, high-mass; and 3) low-temperature, high-mass.
Whether you have an existing system and are shopping for a boiler replacement, or are designing a new system, we offer a full array of options, from our mid-efficiency models offering an economical price point, to our top-of-the-line high-efficiency models with unmatched energy efficiency ratings. Each series is available as a boiler-only, or a combination boiler/hot water heater.
Dunkirk DWB Series Mid-Efficiency Wall-Hung Boilers
The DWB Series of boiler and combination boiler/hot water heater is an easy-to-install, economical choice for residential and light-commercial heating system designs. Available in three sizes – 100,000, 130,000, or 150,000 btu/hr the DWB series is suitable to heat living areas up to 2,500 square feet. They are constructed with a copper heat exchanger, and vent flue gases with single wall category III stainless steel vent pipe. Each model has an AFUE efficiency rate of 85%. Compact and lightweight, the largest model measure only 18”x28” and weights 74 lbs. The inducer fan and gas valve allow for modulation between 33% to 100% of capacity to match the boiler output to the heating system’s demand; if only a single, small zone is calling for heat, the boiler will automatically adjust the firing rate to match it – saving fuel.
Dunkirk DCC/DCB Series High-Efficiency Wall-Hung Boilers
The DCC/DCB is Dunkirk’s cutting-edge solution for those seeking a premium, wall-mount, high-efficiency option. Three sizes are available – 100,000, 125,000, and 165,000 btu/hr models in either a boiler-only or combination boiler/hot water heater configuration. The largest model will heat a living space up to 3,000 square feet. The heat exchanger is constructed of durable, long-lasting 316L series stainless steel; ensuring long service life. The boiler vents with push-fit polypropylene vent pipe or CPVC. All sizes are Energy Star Certified and boast an AFUE efficiency rating of 95%. The burner assembly will modulate to meet the heating system’s demand. The self-diagnostic technology continuously monitors combustion and adjusts gas and air flow for optimization. A novel feature of this product is that it will automatically adjust to either natural gas or propane; no field conversion is necessary.
