Slant Fin Lynx Modulating Condensing Gas Boiler Review

Slant Fin Lynx The Slant Fin Lynx Modulating Condensing Gas Boiler modulates from 25,000 to 85,000 Btuh and has an efficiency of 95% AFUE, making the Lynx an Energy Star Rated boiler. Selecting a Energy Star boiler for your home opens up several “Free Money Programs” that can help with the costs of buying and installing a new boiler to upgrade your older inefficient heating system. These “Free Money” programs are part of the American Recovery and Reinvestment Act, which is designed to stimulate the economy by enticing consumers into purchasing higher efficiency appliances for their homes in an effort to help the manufacturers, and installers who have been doing fewer installations in the poor economy. These programs will also provide consumers with higher efficiency and greener appliances that will lessen our demand for foreign energy and provide a savings in their energy costs while protecting the environment. It is hoped that the savings will also provide an economic stimulus by consumers having more money available to spend on things besides their energy bills. Rebates of up to $200 are available under the Appliance Stimulus Package, Grants up to $6500 are available through the Weatherization Assistance Program to those who qualify, and a 30% Income Tax Credit up to $1500 of the cost to purchase and install a new energy efficient heating system are available.

The Slant Fin Lynx Modulating Condensing Gas Boiler’s high efficiency comes from being a Mod Con boiler as we call them in the trade. In a modulating burner the air and fuel is premixed in a fan as it is sent to the stainless steel burner. This premixing makes the flame very stable and clean burning. In addition modulating burners use a microprocessor-based control, which monitors the operation of the boiler and burner, the microprocessor determines the exact heat demand and adjusts the modulation of the burner to match the demand eliminating cycling of the burner which is very inefficient. This concept is very similar to using the gas pedal in your car and keeps the burner where it delivers maximum efficiency and comfort. The condensing boiler is the second part of the equation. Condensing boilers use an extra heat exchanger section, which scrubs the heat out of the flue gases and uses it to preheat the water returning to the boiler. The flue gases end up having so much heat removed from them that steam in the flue gases condense to water, and the flue gases can be exhausted through PVC pipe. This condensing preheating section utilizes heat wasted in previous boiler designs and is what gives this new generation of boilers their ultra efficiencies in the mid 90% range. The water that condenses from the flue gases are corrosive so the boilers need to be constructed from corrosion resistant materials such as aluminum and stainless steel, and neutralizers are required on the condensate drain. One of the biggest benefits other than energy cost savings is that the flue gases of the Mod Con boilers are quite clean and their emissions meet the Low NOx standards that are being adopted across the country. NOx is a major component of smog and is a greenhouse gas as well so these new boilers are quite “Green.” It is nice to have “Green Technology” that has a payback, as it will become accepted easier by the consumers.

The Slant Fin Lynx Modulating Condensing Gas Boiler can be floor mounted or, wall hung, and fired on Natural Gas or, converted to LP Gas with an optional kit. The Slant Fin Lynx features a cast aluminum heat exchanger that has a low mass and high thermal conductivity which quickly gets the heat into the room instead of spending time warming up the boiler. The modulating burner has a turndown ratio of 3.4:1 with inputs of 25,000 – 85,000 Btuh flowing to its stainless steel burner. The entire boiler when uncrated weighs only 78 Lbs. and measures 34 ¾” H X 18”W X 14 ¾” D. The Slant Fin Lynx features a microprocessor-based control that shows the operating mode and temperature on the display next to the power switch and pressure gauge. The control monitors the heat demand and modulates the burner to math the demand. It also has provisions for outdoor reset with an optional sensor and can provide control of domestic hot water production with options built right in. The Lynx also controls the sequence of operation and monitors status with an LED display showing diagnostic information as well as set up and operating conditions. The Slant Fin Lynx Gas Boiler has spark ignition, gas valve, inlet and outlet temperature sensors, boiler drain valve and condensate trap provided as standard equipment. The Lynx also has sealed combustion with no connection to the air inside the home, all the air connections are to the outside. In residential use Slant Fin Provides a 15-Year Warranty, If properly registered within one-month a 5-Year homeowner Protection plan covers parts and labor, then 5-10-Years the heat exchanger has a replacement warranty, followed in years 11-15 with a pro-rated heat exchanger warranty.

    Sorry, but every boiler should have a no hassle 15(heat exchanger–to sensors) year warranty–as long as it piped correctly!

    If you had to choose between this Slant Fin Lynx model and the Triangle Tube Prestige equivalent, which one would you choose and why?
    My application is direct vent/natural gas.

      Hi Michelle,
      Both are good units and I’d say the most important factor is well qualified service technician availability in your area.
      Just like today’s modern computer controls on cars they function very well for long periods of time but when something goes wrong having the right person working on it is the key.

      For my own personal likes I’d favor the Prestige with it’s stainless steel heat exchanger over the Lynx’s cast aluminum heat exchanger.
      Servicing isn’t a problem with either one for me.

    Thanks so much. More than a few of the reviews I have been reading complain about restart after power outages. Is there validity in that? Outages happen frequently here in the Northeast. Or is that also dependant on proper installation in the first place? Any other advice or thoughts on the Prestige?

      Hi Michelle,
      Computer based controls will always be more sensitive to power interruptions over the older controls. A reset may be required in most cases just like your computer may start with all sorts of scans after a power failure causes it to shut down. In most cases its not a big deal just a reset. In other cases where a power failure was delivered with a voltage spike such as one caused by lightning then anything goes.
