Oil Boiler
Natural gas or oil-burning boiler. Both systems are very efficient, yet with fluctuating, natural gas prices using a more stable price range offered by oil-burning boilers will save revenue for your business.

Stop the potential for a system failure from no natural gas supply to your furnace; an on-site oil storage tank gives you “off-the-grid” oil supply that can guarantee that your fuel demand stays intact. Contact National Mechanical Services to see if an oil burning unit is a good option for you.
Dual Fuel
The benefits of a dual fuel system are the option of switching between the lesser fuel option while still maintaining your heating/process demands. Whether your boiler is oil/gas or gas/wood National Mechanical Services will look to optimize your fuel usage to increase production, save time and revenue.
Schedule an on-site visit today for a system analysis to see if a dual fuel application is right for you. Contact National Mechanical Services.
Gas Boiler
LNG boilers offer the consumer high-efficiency heating for process or comfort applications. Many customers choose LNG heating options where space is limited or due to certain code restrictions. LP boilers, similar to oil-fired, need a holding tank for their fuel supply.
Both systems require good maintenance to maintain optimum performance and save the consumer time and money. National Mechanical Services will provide excellent care and service for all your boiler needs, Contact us today.
Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gases travel through the furnace to second-pass tubes to heat water within the boiler.
Wetback Firetube Boilers
The wetback boiler design features a reversal chamber that is jacketed or completely surrounded by water, which is used to direct flue gases from the furnace to the tube banks. The surrounding water absorbs burner heat, helping improve operating efficiency as heat from combustion goes directly into evenly heating water instead of refractory. The wetback boiler design uses separate tube sheets between tube passes which can be more forgiving with load changes.
Wetback firetube boilers offer a more optimal functional footprint, with lift-off or split-hinged doors that require no cool-down period and can be opened immediately. While there is no expensive refractory to maintain, internal pressure vessel maintenance (i.e., cleaning and tube removal) can be more involved and challenging.
Dryback Firetube Boilers
The dryback boiler reversal chamber has a rear wall that is lined, or jacketed with refractory, which passes combustion gasses from the furnace to multiple tube sheets and reflects burner heat, resulting in exterior radiation losses. The dryback boiler design uses a common rear tube sheet and features convenient fire-side and water-side access.
Dryback boilers have a larger functional footprint due their heavy, vessel-sized rear door which requires sufficient space to open and a cooldown period prior to opening. Dryback boilers also require regular refractory and tube sheet inspection, which can be costly maintenance items.
Most commonly used in hospitals, hydronic reheat allows for a smaller temperature swing in comfort cooling. Heated water loops reheat the air from the cooling coil to maintain the setpoint and dehumidify in the process. The chill water loop has fewer load and unload cycles, as well as longer stabilized runtimes, allowing for better energy efficiency.
Also, an overheated reheat loop can soften Pete’s plugs and open the water loop flooding the conditioned space. National Mechanical Services will check your reheat system to prevent overcooling that can short-cycle the chill water loop, help avoid water damage from melted Pete’s plugs and CO gas leakage possibilities.
