Burning Shield: The Jason Schechterle Story

Product Information

This means that your 5″ flue pipe should be 15″ away from combustibles and your 6″ flue pipe should be 18″ away from combustibles in any direction. Anvil costs for enchanted books are affected by level, rarity and the anvil use cost for the item. Rarity is a multiplier; 1 for common, 1 for uncommon, 2 for rare and 4 for very rare. For example, Advanced Protection IV would cost it's level times the rarity (very rare, 4) for 16 levels to put on an item. Every time an item is processed in the anvil, the next cost is increased by a factor of 2 As already mentioned it is possible to shield a combustible material e.g.a wooden beam from the heat from a heat source. Since wood-burning stoves are used for heating, you will likely use them for mass heating. If so, you will find yourself spending more money on wood fuel to keep the house warm. 3. Reduced Efficiency In the the second diagram (fig.2) the long orange arrow (distance from flue to wood) must be a minimum 15″ (5″ diameter flue) or 18″ (6″ diameter flue). The short red arrows show an area where the gap should be half of this (7.5″ or 9″). The gap between shield and combustible material must be 12mm minimum (BEST PRACTICE 25MM).

It’s worth following the rules and regulations when it comes to wood burning and multifuel stoves. If you have not used or owned a stove before you might not be aware quite how hot the stove and the flue pipe can get. In normal operation a flue pipe will be at 150 to 250 degrees centigrade but can go a lot higher. If deposits attached to the inside of a flue catch fire then a flue pipe can even glow red (worst case scenario and extremely rare). Building regulations must sensibly cover all eventualities (including a pipe glowing red hot) to protect property and life. The floor underneath a stove or in front of the glass can get much too hot to touch and a suitable hearth is imperative. Grey areas? At the end of the day “who is inspecting/signing off the job?” is the real question and it is these people that need to be kept happy. If in doubt err on the side of belt n braces caution.. When installing a heat shield, make sure that it is mounted in a proper location. Otherwise, it will not be able to do its job. You will also risk your home’s surroundings being damaged. Conclusion There must also be an air gap between the shield and the combustible material of a minimum of 12mm (other wise the combustible material soon ends up the same temp as the shield).Plasterboard walls are classed as combustible in Building Regulations and very often cause problems when striving to follow the rules AND YOU WILL LIKELY REQUIRE A HEAT SHIELD AS ALREADY DISCUSSED. A company called Vlaze launched “aesthetically lovely” heat shields (see pic below). “VLAZE wall mounted heat shields are designed to be hung behind a wood burning stove creating a focal point that not only enhances the fireplace but allows the stove to be placed close to the wall behind. When installed the shield reduces the stoves distance to a combustible material by half and in the case of Charnwood appliances down to just 100mm”. Instead of spreading it outwards, heat shields are designed to reflect the stove’s heat towards the room. Such design helps keep the room warm and safe. It also reduces the risk of your home’s surroundings being affected by the heat. 2. Enhance the Stove’s Performance A heat shield enhances the stove’s performance by reflecting more heat into the room. The stove becomes more efficient if it has a heat shield installed. Your new wood-burning stove will be able to heat the space more effectively, so your wood fuel supply will last longer. What Will Happen If You Do Not Use Heat Shields? 1. Damage to the Wall What is the maximum output in kW of your "5kW" wood burning stove? The majority of manufacturers just specify the “nominal output” and this figure means very little in real life. The nominal is a figure the manufacturer chooses to sell the stove at - the stove is capable of reaching at least this output with one fuel load. Nominal means "capable of". But it is not the maximum.

What appears to be a complete mystery when it comes to Building regs, most installation guides and stove manuals is minimum VERTICAL distances to combustible materials (usually a wooden beam or lintel). This distance can be halved if you shield the combustible material. The shield must, of course, be non-combustible (do not use plasterboard as it is not A1 fire-rated and may gradually crumble). Steel flue pipe (often called vitreous pipe) is the pipe that comes out of the top of the top or rear of the majority of stoves. Flue pipes GET EXTREMELY HOT and should be located as to avoid igniting combustible materials. See clause 2.15 and diagram 19 of ADJ ( Document J of the Building Regulations). Note that joints in twin wall are, according to regs, supposed to be able to be inspected and a suitable inspection hatch fitted (30cm x 30cm minimum). One way of achieving this is to make your closure register plate removable in some form (even if removing it is a pain at least you have complied).

Heat shields for wood burning stoves and distance to combustibles Should I be worried about setting something on fire? A wood-burning stove heat shield is a barrier that covers the wood-burning stove. It is installed in front of the appliance to protect a room’s wall, floor, and nearby furniture from the stove’s heat. As a rule, heat shields are made of metal or concrete and are covered with protective paint. Purpose of a Wood Burning Stove Heat Shield
