WHITBY 668-3192 Getting the right caulking High-efficiency oil heat Whether you hire a contractor for draftproofing draftproofing services or do the work yourself, it is important to know something about the materials available for doing the job right. Although there are many types of caulking on the market, some of them are particularly suited to interior use. Tlie three qualities that consumers look for in an interior caulking are lack of colour so that the original paint will show through, lack of odour while curing, and payability payability if the area needs repainting. But there are other important considerations, How easy is application of the caulking? How easily can you clean up after a spill or when the work is finished? How quickly will it cure? Would you prefer a sealant that cures quickly so that you don't have to wait, or one that cures slowly so that it is easy to fix mistakes? And finally, what about price? Generally, everything is relative to the cost and you basically get what you pay for. Health and Welfare Canada suggests the use of acrylic latex inside the home, because it doesn't give off gas as much as other popular sealants. Many contractors recommend recommend the use of acrylic latex, silicone or hybrid caulking, depending on the amount of structural movement in your home, and how easy it will be to air the room while you work and afterwards. Acrylic Latex • paintable • reasonably durable, with 5 to 10 per cent shrinkage, so it is suitable suitable for joints where little movement takes place • semi-water-soluble, easy to clean up or fix mistakes • cures slowly Silicon • long-lasting, durable, high-performance sealant, sealant, with 0 to 3 percent shrinkage. • available in mildew- and moisture-resistant types • clear or coloured • cures quickly, but is very hard to clean • moderately expensive • mild odour • generally speaking not paintable, but some paintable types are available Hybrid Seal • based on high-quality synthetic rubber • clear or coloured • odourless • paintable • 5 to 10 per cent shrinkage Wood Stove Stack Thermometers A stack thermometer on the flue pipe is the easiest easiest way to keep track of how the fire is burning in your wood stove. Look for the type with a metal probe rather than the magnetic magnetic type, and insert it in the flue pipe between If you're buying more oil than you think your furnace deserves, a few dollars spent on tuning tuning or retrofitting may give you peace of mind and help to limit those fuel bills. Another option is to replace your oil furnace or oil burner with a new, more efficient model. But before you make any changes, you should have the efficiency of your present furnace tested. With modern instruments, instruments, an oil furnace efficiency efficiency rating can be produced produced in minutes. In fact, testing for efficiency both before and after tuning is the only way to get a precise precise measure of improvement. improvement. Beware of any 'expert' who scorns the use of test equipment or tries to convince you that efficiency efficiency can be measured by looking at the colour of the flame in the combustion combustion chamber. There are a number of measures that may improve the efficiency of your system. Downsizing the oil spray nozzle may allow a closer match of your furnace's heat production production to your home's needs. It allows less oil into the combustion chamber, reducing the heat output of the furnace. If your furnace furnace switches on for short periods of time, even in cold weather, downsizing should be considered in order to save fuel. If you have added insulation or lowered the. thermostat setting to conserve energy, your furnace is more likely to be too large for the heating needs of your home. The circulating fan in your furnace delivers heated air into your house. It is usually easy to reset this fan to run longer on each heating cycle, extracting extracting more heat from the furnace and circulating it into the living space. A delayed solenoid valve fitted between the oil supply pump and burner nozzle delays oil flow to the nozzle until the pump reaches full operating pressure and the combustion combustion air fan reaches full speed. On both startup and shutdown the solenoid valve reduces the release of unburned oil into the combustion chamber. This reduces soot buildup and keeps the nozzle clean, both of which help maintain the furnace's efficiency, 'Retention head' burners produce a turbulent turbulent flow of combustion air, mixing the oil and air more completely for better combustion. This is more TYPICAL OIL BURNER Mounting Flange Transformer Retention head Nozzle- Oil pumpj Combust air Fan Housing on expensive than the other options described but may provide better fuel saving's. An older or unreliable burner should be replaced by the highest efficiency burner available. This will often be a retention head or similar unit. If the efficiency efficiency of your furnace is 77 per cent or higher, it is not worth spending any money on a new burner because 87 per cent is the highest level of efficiency that you could expect to get with oil. If the efficiency efficiency is lower, and you decide to retrofit rather than replace the furnace, be sure that the entire fur nace assembly still has a few years of useful life, so that the savings will cover the cost. The newest retrofitting retrofitting option is an add-on condensing heat exchanger. exchanger. It contains two water sprayers that absorb heat from combustion gases. The warm water is then pumped into a coil that transfers the heat to the circulating house air. This device is only certified to be installed with some furnaces, furnaces, so check with a dealer to see if it is compatible compatible with your system. This is the most expensive option, but it produces very high seasonal efficiency efficiency ratings. The condensing condensing heat exchanger is also available as an add-on to many new oil furnaces. The seasonal efficiency of this option is expected to be 90 to 95 per cent. If you have any questions about your oil furnace, your service mechanic is a reliable source of information.

For the best performance the flue temperature temperature should not exceed 330°C or fall below 110°C during normal operation. Some burning about fireplace questions inserts OVER $400- VALUE As attractive as it may be, your open fireplace fireplace may become less appealing when you consider consider that as much as 700 m 3 of warm household household air is going up the chimney every hour. This heat loss, when combiner!' with interior air leakage*, 1 can destroy any appeal of an open fire. More often than not, the effect of a cosy fire is to cool the space it serves. But this doesn't mean you have to seal it up. Instead, you can satisfy your fondness for flames with a fireplace insert, a small airtight stove designed to fit into the existing hearth. For a $1000 td $1400 investment, investment, you can improve your fireplace's performance performance while adding to its elegance. Supplement your heating system While most modern fireplaces are not designed to replace a home's heating heating system, they can provide provide supplementary heat if retrofitted with inserts. Inserts make the most of heat from burning wood and prevent heated room air from escaping through the fireplace and up the chimney. Most inserts are designed for controlled combustion, so that the flow of air feeding the fire is precisely ' regulated. Inserts equipped with double double walls and circulating fans are even more efficient. efficient. All types of inserts are relatively easy to install. arid iobk'great 1 ; ;tpo.l,: ' ' . The only problem' with inserts, as with open fireplaces, is the possibility possibility of fire hazards. Two areas of concern associated associated particularly with fireplace fireplace inserts are creosote buildup and overheating. The buildup of creosote, creosote, a flammable tar deposited by hot smoke on the cooler inner surface of a chimney, is more likely with the low-temperature fires permitted by controlled controlled combustion inserts. Overheating in the fireplace fireplace cavity can also occur with inserts, since the cavity is no longer open to cooling room air, as with open fireplaces. Both hazards can be minimized by avoiding low-temperature fires, using only dry, well seasoned seasoned wood, checking for creosote deposits monthly (more often in spring and fall), ensuring that the insert has an insulated outer skin to minimize heat transfer to the fire place cavity, and by cleaning cleaning the chimney regularly. Have the installation inspected Before installing an insert, have a qualified chimney sweep check the condition of the chimney and ascertain that ttiè fiue ; tile liners are' in good Repair. Obtain a building permit, and have the fire department, or a building inspector inspect the installation. Proper installation installation requires a tight connection connection to the chimney flue so that creosote does not seep back into the fireplace fireplace cavity. As with any major appliance, shop around before you buy. Check warranties and certification certification to ensure that the insert is approved by a recognized testing agency, such as the Canadian Standards Association (CSA), Underwriters Laboratories of Canada (ULC), or Warnock Hersey Professional Services Services (WH). And last but not least, enjoy your fireplace insert. You'll find it more comforting than your old fireplace, both physically and financially.
