Since the cover is a few inches off the ground, as it should be, a considerable draft is possible making the tipi nothing more than a temporary shelter, not really fit for living in.

Why would I ever need to have my original chimney liner replaced?

HomeSaver Web Site

Cracked clay liner tiles and the deterioration of mortar joints between liner tiles can lead to the leakage of flue gasses into the interior of the house. Those flue gasses contain Carbon Monoxide, a deadly, odorless, colorless gas. Cracks in your chimney liner can also cause dangerous heat transfer to combustible material surrounding your chimney.

How do I know if I need a new liner in the chimney?

FAQs
A wood burning appliance (wood stove or fireplace) needs a "class A" chimney of proper size. This basically means that the chimney must be structurally sound, with a tile liner, or its equivalent. The liner in the chimney is to contain the liquid creosote so that it does not seep into the masonry structure. In the event of a chimney fire, this liner helps to contain the fire, so it does not spread to the surrounding combustibles.

What is a chimney liner?

FAQ Section on Chimney Cleaning, Chimney Caps, Gas logs, Gla...
Currently, most masonry chimneys are built with terra-cotta clay tiles stacked and mortared inside the brick structure. These tiles serve as a gas-tight and heat-resistant insulator against the masonry structure. Without a liner, or with cracked and damaged liners, there would be heat transfer or actual seepage through the brick and mortar. A liner is a stainless steel tube inserted into a chimney to draft an furnace, woodstove or fireplace.

Why do I need a stainless liner in the chimney when I already have a clay liner?

Northwest Stoves Ltd. - Frequently Asked Questions
The chimney flue should be the same size as the appliance flue collar. In the past, many chimneys were too large for the appliance they served. But bigger is not better when it comes to chimney size. Flue gas flows faster and has less time to lose heat in a smaller chimney flue. In planning wood-heating systems, some experienced installers even choose a chimney that has a smaller inside diameter than the appliance flue collar.

How can I know if my chimney liner is cracked or damaged?

HomeSaver Web Site
That requires a thorough inspection. This is a case where a chimney professional would most likely use a video inspection system of some kind so he could systematically inspect every tile in your chimney's flue. Such an inspection will be able to show any cracks, even small ones, in your chimney tiles and/or any damage to the mortar between the clay chimney tiles. Once again, you could then view the results of that video inspection yourself.

What is the purpose of the chimney? Why does the chimney need to be so tall?

AVE - FAQ
The purpose of the chimney structure is to prevent the warm buoyant air inside the chimney from mixing with the surrounding cooler ambient air outside the chimney via entrainment. Without the chimney, the warm rising air from the solar collector would quickly mix with the ambient air which would rapidly reduce its buoyancy. The maximum efficiency of a solar chimney is proportional to its height; the taller the chimney, the more work can be captured by the turbine.

Why Does Down Insulate So Well?

FAQ
Down warms without weight. It takes 14 wool blankets to equal the temperature control of one down comforter. Each down cluster traps more air for its weight than any synthetic fiber. Every ounce of down has about two million fluffy filaments that interlock and form a protective layer filled with air that keeps warmth in and cold. Down is wonderfully resilient. You can flatten it and with a good shake it will bounce back to its original loft while providing you with natural warmth.

Do I need to insulate the floor in my basement?

Insta-Insulation
YES. The floor and walls are a significant source of heat loss. An insulated floor is warmer and drier; and it has direct influence on your comfort. Putting carpets on a floor only makes it feel warmer. If you have a heated floor insulation is very much necessary, as the heat loss through the floor would be higher than 50%. This heat loss is a huge and unnecessary waste of money. Return on investment for floor insulation is very quick, mainly because of the low cost of INSTA-PANELS®.
