Iha 2011 August Webinar - Modine
This quiz was created tp review the 2011 IHA Ed. August webinar presented by Modine.
- 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
