How To Make A Chimney Sheep?
Are Chimney Sheep any good? A few customers have asked whether there are have been any comparative reviews between Chimney Sheep™ and Chimney Balloon. The Chimney Sheep is easy to insert and easy to remove, and being made of sturdy Herdwick wool it is very durable and will last for many years.
How do you measure a chimney for a sheep? Get a tape measure. If you have a round flue, measure the diameter. If you have a round flue, you want a round sheep that is an inch or so larger than the flue. If you have any other shaped flue, measure the depth and width of the nearest narrowest part.
How do you Draught proof a chimney? Draught proofing chimneys with chimney balloons
You can use a chimney balloon. A chimney balloon is essentially a balloon that you inflate in your chimney that creates a snug fit, thereby preventing hot air escaping up out of the chimney or cold air dropping down it, helping to prevent draughts in your home.
Another great way to block cold air is with a chimney balloon or plug. These devices are placed above the throat damper and inflated to completely block air from coming down into your fireplace. Balloons are designed to be used only when a fire isn’t burning.
Never, under any circumstances seal off the top of the chimney, due to the risk of unintended use of the fireplace as cautioned above. By keeping the cap on the chimney but sealing the fireplace, enough air can circulate to avoid unwanted condensation issues. This is the WRONG WAY to Block a Chimney!
The Chimney Sheep is designed for open solid fuel fireplaces and chimneys. If the gas has been disconnected then a Chimney Sheep can be fitted in the flue but otherwise we advise against it. For customers with gas fires we recommend the Chimney Balloon.
Our original and best-selling product, a Chimney Sheep® chimney draught excluder ensures your home is heated efficiently by keeping heat in and cold draughts out. Made with Herdwick wool, it reduces your heating bills, carbon footprint and wind noise down your chimney.
The plastic Chimney Balloons can be blown up manually and are inserted into the throat of the chimney. However, while they were easy to use, these widely-used inflatables don’t actually perform well in preventing air leaks and helping you maximise your home heating and cooling!
The Chimney Sheep needs to be an inch or two bigger than the opening in order to hold itself in place. The wool is compressive so it will squash to fit a range of shapes and sizes. And it can be trimmed down a little with sharp scissors if necessary.
Keep warm air in and cold air out with Chimney Balloon ®
The Chimney Balloon effectively blocks the chimney, stopping warm air from escaping and stopping cold air from getting in.
The Chimney Balloon is made of extraordinarily tough plastic. But when it gets hot, it will just shrivel and fall into the grate. Other inflatables are made of PVC which expands and gives off fumes – the Chimney Balloon is by far the safest!
What’s more, between 80 and 90 percent of the heat produced by wood burned in an open fireplace is lost up the chimney. This means that for every $100 you spend on firewood, you get only $10 to $20 worth of heat. The rest goes up the chimney.
Using a Fireplace Draft Stopper
A fireplace is a huge source of drafts from the cold outdoors. A chimney can act as a wind tunnel even when the damper is closed, sucking cold air down into your home through the fireplace opening.
Fireplace and chimney basics
The path for smoke also is a path for air. When a fireplace isn’t in use, cold air from outside can come down the chimney into the home, and warm interior air can escape up through the flue.
Often, when cold air is being drawn down the chimney, the cause is an improperly sized chimney. Chimneys that are too short or too large for the fireplace appliance can allow cold air into your home through the chimney.
Often, the source of cold air coming from the fireplace isn’t an issue caused by the fireplace. Rather the home is under negative pressure and using the fireplace as it’s source of “makeup air”.
#1 The Simplest Cause of Chimney Leaking: Rain Going Straight In from the Top. Chimneys without covers get a lot of rain falling straight down into them. A chimney cover makes sense to most people. Not only does it keep the rain out, but keeps birds, animals and debris out.
A chimney needs a vent, not just at the top (provided by the cap) but also at the bottom. The air flow helps keep the chimney dry and ward off any condensation forming inside the stack. If there is no air flow, condensation will form inside the stack and will be soaked up by the old coal soot.
Do Unused Chimneys Need Ventilation? Yes, chimneys need to breathe, even if they won’t be used anymore. This will allow air to pass through the chimney and help prevent problems caused by moisture. If your damper is near the firebox, you can use insulation to seal the chimney.
Put a ventilated rain cowl/cap on the chimney pots. Take loft insulation 600mm up the chimney breast stopping it just below the air brick, and bring insulation inside the flue up to this same level.
Just push the wool head into the narrow part of the flue. You may need to tug it down gently to ensure a good fit. That’s it. When you want to remove it, pull gently in case there is any debris collected on it that has fallen down the chimney.
Couple of ways, either use light weight blocks or stud board and skim. Whichever way make sure you install a vent, and fit a rain guard on the chimney pot. This will stop water getting in and keep stack aired.
However, if you want to permanently close up your chimney, cutting out a foam insulation plug and placing it in the bottom of the chimney and caulking around it is the best method. You can also seal the edges with foam weatherstripping tape, too.
When fitting into an existing fireplace, be aware that heat can be lost up the chimney, reducing efficiency, and up-draught can affect the operation of the fire. To prevent this, it’s recommended that the chimney flue is blocked off – a chimney balloon is a good way to temporarily block up your chimney.
