>> Adapted from a fact sheet by John Bartok, many excellent articles are on

>>
>> Service all heating units. The efficiency of most greenhouse heating
>> systems can be improved by at least 5%; have a competent service person
>> clean and adjust all furnaces. For oil furnaces: Change the fuel filter, it
>> is surprising how much sludge and dirt collects in the fuel. Replace the
>> nozzle. Wear increases the nozzle orifice opening increasing fuel usage.
>> Select a nozzle with the correct spray angle to fit the firebox. Follow the
>> manufacturers' recommendations. Replace and adjust electrodes. Inspect
>> safety controls including cad cell sensor, transformer, limit switch and
>> fan control. On propane units check gas regulators for proper pressure
>> settings and to be certain the regulator and gas port vents are not
>> plugged. Tank relief valves should be replaced every 5 to 10 years.
>>
>> Heat exchangers. Soot should be removed from heat exchanger surfaces. A
>> 1/8-inch soot deposit can increase fuel consumption by as much as 10%.
>> Brush and vacuum surfaces or clean them with special cleaning compounds.
>> Exterior heat exchange surfaces, such as tubes, fins and radiators also
>> collect considerable dust and dirt in a greenhouse atmosphere. Brush and
>> vacuum surfaces to increase heat output. Clean blowers for efficient air
>> movement.
>>
>> Combustion Efficiency. Efficiency testing of a furnace or boiler is a 10
>> minute procedure that can indicate when problems begin to occur. It is the
>> key to saving money on the heating bill. Increasing efficiency one or two
>> percent can significantly reduce fuel consumption over the year. For
>> example, a 2% increase in efficiency of a million Btu/hr burner operating
>> 3300 hours from September to May will save about 650 gallons of fuel oil.
>>
>> Combustion Air. The combustion process combines the carbon in the fuel
>> with the oxygen in the air. The lack of adequate oxygen results in
>> incomplete combustion and carbon buildup. A 400,000 Btu/hr furnace will
>> require about 100 cu ft. of air/minute to operate efficiently. In tight
>> poly and glass greenhouses, a makeup air supply of 1 square inch of intake
>> area/2000 Btu/hr burner input should be available from a pipe or louver
>> through the endwall unless a separated-combustion heater is installed.
>> These are installed with a direct connection to outside air.
>>
>> Flue pipe connections. These should be tight and the chimney should
>> extend at least 2 ft. above the ridge of the greenhouse. The top of the
>> chimney should be at least 8' above the combustion chamber and have a cap
>> to prevent backdrafts and possible air pollution injury to plants.
>>
>> Controls. Accurate controls are important to achieve high efficiency. The
>> payback of replacing an old mechanical thermostat with a new electronic
>> thermostats having a +/- 1 degree F differential is very short. The sensor
>> should be shielded and aspirated with a small fan to quickly sense changes
>> in the environment.
>>
>> Heat Distribution. Air circulation will reduce temperature stratification
>> in the greenhouse. Installing horizontal air flow (HAF) fans that move the
>> air at 50 to 100 feet/min can limit temperature differences to no more than
>> 2 degrees at any point in the growing area. Use 1/10th horsepower
>> circulating fans located 40' to 50' apart to create a circular flow pattern.

>> HOT WATER SEED TREATMENT WORKSHOPS - MARCH 3 AND 5
>>
>> Hot water seed treatment is an excellent tool to help control harmful
>> diseases inside and on the seed coats of vegetable seeds. On March 5th Meg
>> McGrath, Plant Pathologist from Cornell, is coming to the UVM Horticultural
>> Research Center in South Burlington, on Green Mountain Drive, to deliver a
>> seed treatment workshop from 9am-1pm. We will have 2 sets of hot water
>> baths, thermometers and all the materials you will need to treat your own
>> seeds. Check the list of appropriate seeds here, click on 'Table 1'
>> http://vegetablemdonline.ppath.cornell.edu/NewsArticles)/
>> HotWaterSeedTreatment.html#Table1.) Bring your seeds and something to
>> weight them down (bolts, etc.) so they sink in the baths. For more info on
