Space Heating and WETT Inspections

Space heating involves a self-contained device for heating an enclosed area. Space heating is generally employed to warm a small space, and is usually held in contrast Wett Inspections - Newer Wood Stovewith central heating, which warms many connected spaces at once. The inspection includes ensuring manufactures installation instructions are followed and wood burning units are installed in accordance with their listing requirements. The verification of installation is done by a Certified Inspector. Space heaters which do not have a ULC or other agency’s Certification Data Tag will have to have 48 inches of clearance from combustibles. This is an important part of the Inspection and home owners can easily verify for themselves whether of not their space heater is Certified prior to paying for an inspection.

Newer style space heaters are more efficient than previous models with some have catalytic inserts that burns with a higher efficiency.  The catalyst needs to be replaced every 5 years or so.  Even though catalytic stoves are recommended for home owners who are replacing a major part of their homes heating there are non-catalytic stoves which have a secondary combustion chamber which helps reduce emissions.  New stoves can produce 90 % less particulate and smoke emissions.

Ninety percent less smoke means 90 percent less creosote. This gives two important benefits. First, the chance of chimney fire is virtually eliminated, as long as the stove is operated correctly and reasonable maintenance is done. And second, the flue pipe and chimney will need cleaning much less frequently, which is another way the new technology stoves save time and money.

If you want to heat most or all of your house with a wood stove, try to meet these two objectives: First, the heater should be located in the area where the family spends most of its time. And second, there should be ways for the heat to flow to other parts of the house. These conditions are not usually difficult to meet, but they do need to be planned.

Correct stove sizing is important because a stove too large for the heat demand of the space will be operated with slow, smoldering fires much of the time to avoid overheating the room, and an undersized stove can be damaged by frequent over-firing to keep up with heat demand.
