Dunkirk Water HeatersDunkirk DXL-K Boiler
DXL-K
The DXL-K is a gas-fired boiler with quiet and highly efficient operation. Its energy-saving features include the electronic ignition system and motorized vent damper.
The internal Hydrolevel control adjusts the water temperature based on your heating system demand, which further reduces heating costs. The built-in low water cutoff (LWCO) protects the boiler from potentially dangerous low water levels.
The DXL-K offers more installation flexibility with water and gas piping options available out the left or right sides of the boiler.
Dunkirk PSB Boiler
PSB
We’ve been making American steam boilers for more than 80 years. Dunkirk’s Plymouth Steam Boiler (PSB) offers a great combination of heating comfort, efficiency and Dunkirk dependability. With an AFUE as high as 82.7%, a Plymouth Steam boiler is an outstanding choice for performance and economic operating cost.
Dunkirk WPSB Boiler
GAS BOILER
The Dunkirk WPSB gas boiler is available in 7 sizes and an AFUE of up to 84.1%.
The WPSB features an advanced Fuel Smart Hydrostat 3-in-1 Control:
The WPSB features an Integral Draft Hood and Vent Damper, reducing the overall height and making the unit ideal for low clearance/space limited installations.
The compact footprint and Cast to Last, 20-Year Non-Prorated Limited Warranty make the WPSB an excellent choice for residential applications.
Dunkirk XEB Boiler
XEB
The XEB Gas Fired Hot Water Boiler is available in 5 sizes and an AFUE of up to 84.4%.
The XEB features a Honeywell High Limit/Electronic Control.
Control monitors the water temperature and delays the burner starting until residual heat has been transferred. This maximizes efficiency by turning on the burner only when needed.
An Induced Draft Fan allows flue gasses to be pulled throughout the boiler and exhausted through a chimney or side-wall vent.
The XEB features a small compact design, ideal for low clearance installations and a Cast to Last, 20 Year Non-Prorated Limited Warranty.
Dunkrik H20 Indirect
H2O GL
The glass lined tank offers a solution in those problem areas where high chloride levels in the domestic water supply can corrode a stainless steel tank. The tank and coil are made of steel, with enamel coating on the surface. The internal coil delivers unmatched performance with a large surface area resulting in high domestic hot water ratings. The tank tapings are 1″ to accommodate higher flow rates.

Our A/C was 30 years old. T-Mark answered my call right away and came out the next day, replaced the Furnace and A/C. Crew was professional and seemed to know what they were doing. Seemed to get everything done without any hiccups or problems. Took time to go through everything with me. Very happy customer.

Kevin and Bryan did an awesome job installing my air handler HVAC system and HWT. They were professional friendly and knowledgeable. Ian who sold me the system was friendly and knowledgeable and knew about all the rebates and incentives available saving me thousands. T-Mark of West Seneca hands down is the best for HVAC/Plumbing service. I highly recommend them.
Michele M
T-Mark installed my air conditioning unit 4 years ago. Very pleased with their work. I recently had them out to do a look and tune up on my unit. Everything from scheduling an appointment, to the actual service being performed was top notch. “Big Mike” came out for the service and he was absolutely wonderful. On time, very friendly. Took the time to answer all my questions. I hope nothing ever breaks and I need service, but if I do T-Mark will be my first call. Highly recommend!
Tanner R
T-Mark is WONDERFUL. I was able to get a next day appointment, and Brian came out to help. He was able to resolve the issue within an hour and also teach us why it happened, how to prevent this, and what to watch for moving forward. I would definitely recommend and use them again.

T-Mark was a 5 star experience from the very first phone call to the end of the project. Every person on the team met us with kindness, eagerness to help and professionalism.
Garrett Moffett
Had a leak in my water heater, I called many places and they were the first to come out. Fixed quickly and had no issues since.
Dan Verdi
Derek and his team were prompt, professional, accommodating, friendly, efficient and tidy. I have had a few jobs done through T-Mark (Hot Water Tank installation, etc.) and I keep going back to them because they’re dependable for all the reasons I listed above. Today, my new A/C and furnace installation was flawless. They’re my first and only call because they’ve earned my business, over and over.
Nicole Marie
Had an issue with toilet not flushing, so I called before business hours. T-Mark got back to be very quickly and had someone out less than 2 hours. The technician I had was Brian, and he was great. Let me watch the whole process of snaking the sewer line, and explained everything thoroughly. Very friendly, and overall I’m very happy it’s all fixed. Thank you!

Jon Stachura was totally professional, respectful and congenial. He was actually available two hours earlier than expected. He quickly diagnosed the leak problem and offered best and worst case solutions for repair. Jon was mindful of the customers property. While he was initially expected to arrive between 12 & 2, he actually completed the job by 12:15pm. The job was not simple. It involved Jon opening a wall and removing a 125 year old section of iron plumbing stack and replacing with pvc pipe. Very pleased with his work. Thank you Jon and TMark!!!
Charles Dean
Brian Borkowski did a great job snaking the drain pipe to the bubler. He did a fine job explaining what he was doing and the condition of the drain system.
I’ve always been satisfied with T-Mark plumbing.

I have had a nightmare of a time with the plumbing in the house I moved into a year ago. T Mark sent Seth out quickly, he was fast, professional, explained everything in detail, and was very understanding when I was very stressed. It’s very easy and efficient to schedule, company is great with communication, it was refreshing to be treated respectfully, would absolutely recommend and will use in the future.
