Questions and Answers
  • 1. 
    The best method for creating opportunities to sell greenhouse heating equipment is:  
    • A. 

      Stay close to the phone in the office in case a call for an order comes in.

    • B. 

      Go to church and pray for cold weather.

    • C. 

      Cut small holes in greenhouse coverings to increase heat-loss & burner hours.

    • D. 

      Look for signs of inefficient or worn/damaged heating equipment and start a dialog with the grower about their annual heating costs.

  • 2. 
    Gas-fired unit heaters are a popular choice for greenhouse heating because:  
    • A. 

      Multiple unit redundancy avoids the risk of crop losses in a no-heat situation.

    • B. 

      They have low up-front & life cycle costs per Btu of output.

    • C. 

      They safely vent harmful flue products like ethylene, carbon monoxide & water vapor outside.

    • D. 

      All of the above…and more.

  • 3. 
    What 2 things identify a grower that is currently wasting fuel on gravity-vented heating equipment?  
    • A. 

      Small motors at the top of the unit & horizontal vent runs

    • B. 

      Enclosed combustion chambers & 2-pipe venting

    • C. 

      Open draft diverters at the top of the furnace & large diameter vertical vent stacks

    • D. 

      None of the above

  • 4. 
    The big reason why gravity vented unit heaters are the most inefficient type is because:  
    • A. 

      Heat exchangers are different.

    • B. 

      Warm indoor air escapes through the open draft diverter & large diameter vertical stack.

    • C. 

      Standing pilot flames in the burner run continuously.

    • D. 

      All of the above

  • 5. 
    Replacing failed heat exchangers in gravity vented unit heaters is a waste of money because:  
    • A. 

      The combined parts & labor costs may be as high as replacing the entire unit with a new one.

    • B. 

      Replacement heat exchanger warranties are typically 6 months vs. 10 year warranties on stainless steel heat exchangers on new units.

    • C. 

      A repaired gravity vented unit is still wasting energy costs at only 65% seasonal efficiency.

    • D. 

      All of the above

  • 6. 
    In addition to saving heating costs over gravity vented unit heaters, separated combustion unit heaters last longer because:  
    • A. 

      Heat exchangers & burners are protected from the high-humidity and chemical vapors commonly found inside greenhouses.

    • B. 

      Two small vent pipes are better than one big vent pipe.

    • C. 

      They are heavier than gravity vented unit heaters.

    • D. 

      None of the above

  • 7. 
    At 93% minimum thermal & seasonal efficiency, Modine’s Effinity93 high-efficiency separated combustion unit heaters are the most efficient gas-fired unit heaters in North America.  
    • A. 

      True

    • B. 

      False

  • 8. 
    When units with different efficiencies are heating the same space, the combined efficiency is maximized by:  
    • A. 

      Setting the thermostat a little lower on the most efficient unit than the least efficient unit.

    • B. 

      Setting the thermostat a little lower on the least efficient unit than the most efficient unit.

    • C. 

      Both

  • 9. 
    If a grower refuses to buy Efinity93 units in a part-year greenhouse because fuel savings payback is too long, the next best step is to ask the grower if they would consider:  
    • A. 

      Seeing a psychiatrist.

    • B. 

      Forgiving you for trying to talk some sense into them.

    • C. 

      Replacing the failed unit in the part-year greenhouse with a working unit from one of their full-year greenhouses and replacing the unit from the full-year greenhouse with an Efinity93, thereby boosting their efficiencies in both greenhouses with a single unit.

    • D. 

      All of the above

  • 10. 
    Options for growers to help defray the up-front cost and shorten the payback period for upgrading to high-efficiency heating equipment include:  
    • A. 

      Government tax incentives & grants for capital expenditures & efficiency upgrades

    • B. 

      Natural gas utility rebate programs for high-efficiency equipment

    • C. 

      Finance & leasing options on commercial equipment from financial services companies familiar with the horticultural market.

    • D. 

      All of the above
