|
|
| New well-insulated buildings with R28 wall, R40 ceilings, insulated basement walls. Normal sizing allows for one picture window and one patio door. Calculation does not allow for extremely large glass or air exchange heat losses. Homes that are not well insulated are not applicable in this calculation. Use previous heating history to determine sizing. |

|
| *Full cords of medium to high-quality wood. |
| **Improperly insulated radiant slab heating can dramatically affect sizing requirements and heat load. |
| Be sure to consult your dealer when sizing. Previous heating efficiencies and heat loss need to be considered when sizing a furnace. This is only a guideline. |
