Pellet Stove Sizing Basics Guidelines for Sizing and Installation of High Efficient Pellet Fueled Heating Units
Pellet Stove Sizing Basics A Pellet Stove
Pellet Stove Sizing Basics Identifying the area to be heated Keep in Mind the following: • The new pellet stove will not equal the BTU output of an existing larger wood stove. • Be realistic with the area to be heated. “Don’t over promise and under deliver”. • The new pellet stove heats mainly through a fan and convection and is not as intense as a wood stove with radiant heat transfer.
Pellet Stove Sizing Basics Sizing Basics 1. Measure the floor area of the entire area that will be heated by the new pellet stove. 2. Measure the ceiling height or average it, if cathedral or multiple height area. 3. Multiply the floor area x the ceiling height to calculate the cubic volume in square feet of the area.
Pellet Stove Sizing Basics Leakage adjustment factors • Use “4” for a factor if the area is considered tight (Under .6 AC/H Natural). • Use “5” for the factor if the area is considered average (.61 AC/H to .85 AC/H Natural). • Use “6” for a factor if the area is considered loose (Above .86 AC/H Natural). • Refer to BPI Standards to change CFM 50 to natural air change per hour.
Pellet Stove Sizing Basics The Final Step • Once the cubic volume is calculated you must then multiply the volume by the “Leakage Adjustment factor”. • For example: an area with 4000 cubic feet of air in an “average” home would require: 4000 x “5” = 20,000 BTU/Hr. output from the new Pellet Stove. Let’s look at some examples-
Pellet Stove Sizing Basics Example 1 - Old Farmhouse
Pellet Stove Sizing Basics Example 1 Old Farmhouse An old Farm House with an existing large wood stove. The heated area is 768 Sq. Ft. with 8.0 Ft. Ceilings and is considered “Loose” • 768 x 8.0 x “6” Factor • 6144 Cubic Feet x “6” Factor = • 36,864 BTU/Hr. output of the new Pellet stove.
Pellet Stove Sizing Basics Example 2 - Manufactured Home
Pellet Stove Sizing Basics Example 2 Manufactured Home A Manufactured Home that is 908 sq. ft. and the living room is 332 sq. ft. to be serviced by the new pellet stove. The unit is considered “Loose”. (12’ x 21’)+(5’x 16’) x 7.5’ = total Cubic ft. volume • 252 + 80 =332 x 7.5’ x “6” = 14,940 Btu/Hr. output of the new pellet stove. • If you cannot perform a blower door test, estimate as accurate as possible - DON’T OVERSIZE!
Pellet Stove Sizing Basics General Recommendations •
Heating System Replacement and New Installations
•
Replacement System Sizing
•
New installations of heating systems must be designed and sized based on actual heating load calculations for the building.
•
Acceptable sizing calculation methods include ACCA Manual J and Manual S, IBR load calculations, or other comparable calculation procedures. Replacement systems may not be sized larger than the existing system without providing a load calculation verifying the need for a larger system.
•
It is recommended that blower door test results are used to determine the building air leakage rates input into load calculations.
Pellet Stove Sizing Basics General Recommendations cont. • The listed efficiency for a new stove must be used. • In the event no efficiency is listed, input 78% for the efficiency of the new proposed stove for program application and software.
Pellet Stove Sizing Basics General Recommendations cont. • Contractors must keep in mind location of controls. These stoves can effect the comfort of the rest of the home. The main thermostat could see heat from this appliance and not call for heat, this will make the rest of the home cool down.
Pellet Stove Sizing Basics General Recommendations cont. • Many of the units are Mobile Home approved and require additional safety precautions. • All must be installed with a dedicated direct source of fresh air for combustion (See installation instructions for each unit). • Mobile home units are required to be secured to the floor. •
FOLLOW ALL MANUFACTURER’S INSTRUCTIONS AND LOCAL CODE REQUIREMENTS.
Pellet Stove Sizing Basics General Recommendations cont. • In regards to outside air for combustion of the new pellet stove, this program is requiring that fresh air be installed to the manufacturer’s installation manual. ONLY in extreme situations will a stove be allowed to be installed WITHOUT combustion air. • An example of this would be a unit in the middle of a home with a distance longer than the installation instructions maximum combustion air pipe length.
Pellet Stove Sizing Basics General Recommendations cont. Pellet stove accessories may also be included with the new unit such as: • • • • •
Thermostats Pellet hoppers Storage bins Automatic pellet feed systems Back-up power system (must service stove only, and be manufacturer's listed accessory product, or not void warranty.)
Pellet Stove Sizing Basics General Recommendations cont. When purchasing pellets, look for 3 key things 1.
BTU content per pound or bag; The higher the btu’s the better the pellets.
2.
Moisture content; The drier the pellet the better the burn.
3.
Ash production; Lower production of ashes is both a sign of good fuel and also a critical element to the operation of the stove.
4.
Sample different Pellets for best performance of the new stove
Pellet Stove Sizing Basics General Recommendations cont. • As a best practice, homeowners should buy their pellets in the largest quantity that they can store to obtain the best price and should also look into delivery of pellets. • Store the fuel in a cool dry place that is outside the home, but protected from the weather and direct sunlight. • Install a CARBON MONOXIDE DETECTOR in the area that the pellets are being stored in.
Pellet Stove Sizing Basics General Recommendations cont. In the event of a power outage, there are many ways to supply power to the unit. They range from whole house generators to battery back-up with a power inverter. The power inverter must have a “continuous output” of 400 to 600 watts based on the unit’s electrical requirements. The inverter must be connected to a fully charged high quality deep cycle battery to supply power to the inverter.
Pellet Stove Sizing Basics General Recommendations cont. Wood stoves in many cases were used to heat entire homes. The largest eligible Pellet system can produce 50,000 BTU/Hr. This decrease in heating capacity must be reviewed with the homeowner. Other insulation and air sealing improvements can significantly reduce the total heat loss of the home and should be strongly promoted.
