For over the past 20 years, Miles Industries has introduced thousands of North American Families to a whole new type of fireplace, one that is quite distinct from traditional hearth products. It's called the Gas Fireplace, and although it take many forms, it is defined by features and benefits that have proven to be especially useful and popular with our customers.
Effectively, Miles Industries has played a major role in revolutionizing the fireplace industry. In fact, knowledgeable people within the industry acknowledge Miles leading role in first pioneering and then advancing the technology of gas fireplaces.
To help you better appreciate the important features and benefits of our products and assist in the selection of an appropriate model, we offer the following guide to the selection of your gas fireplace.
Forced air central heating systems distribute heated air from a central furnace unit through ducts to various points in the home. The furnace burners cycle on and off as often as 3-4 times per hour depending on the thermostat's setting and sensitivity. Typical furnace gas inputs range from 80,000 to 120,000 BTU/hr and are sized to heat the home in the very coldest weather. During average heating weather, furnace "on cycle" times may be relatively short with the burners shutting down before peak efficiency is even reached. This results in reduced efficiencies through "cycling losses" (like a car's mileage in stop and go traffic). Also, room comfort levels fluctuate along with furnace heat cycles, sometimes warm one minute and cool the next. With central furnace systems, it's often necessary to overheat portions of the home just to get comfortable in the area you wish to spend time.
By contrast, an efficient Valor gas fireplace zone heater puts warmth directly into the space you wish to heat with virtually no cycling losses. Valor heaters utilize special lightweight steel and ceramic components to heat up quickly and reach efficiency in minutes. With a Valor installed in one or more of your main living zones, you can enjoy increased comfort while reducing furnace usage in colder weather or eliminating it during warmer Spring and Fall weather.
A BTU or British Thermal Unit is the amount of heat required to raise 1 pound of water 1 degree Fahrenheit. All gas appliances are rated in BTU's/hr Input which is an approximation of the amount of gas consumed on full fire in one hour as expressed in terms of the heat potential of the gas. Depending on the design and efficiency of the appliance, a certain proportion of the heat generated from burning ends up as useful heat in the room (Heat Output) while some portion is lost to vents and chimneys (Flue Loss). All Valor models are tested and certified to Heater standards and therefore are rated for Heat Output. This is determined at full fire, without optional blowers and after the heater is up to operating temperatures.
The amount of heat you will require will depend on a number of factors such as room size, insulation levels, amount and type of windows, climate and the type and use of other heating systems in the home. It will also vary from hour to hour, day to day and season to season because of these same factors. To give you a general guideline, studies average winter home heat requirement was between 10,000 and 20,000 BTU/hr. Specifically, a 1300 square foot house in Vermont with average insulation required 14,000 BTU/hr in January and February.
The Comfort Zone is that area in your home that can attain an even comfort level using a steady burning efficient heat source like a Valor fireplace Heater. Depending on your house layout and fireplace location, the Comfort Zone may be one room or a complete level or zone. In Fall or Spring, a Valor may easily provide comfort for the entire home. The amount of BTU's of heat necessary to maintain this Comfort Zone is in the range of 5,000 to 15,000 BTU/hr. This relatively small amount of heat can be very effective, especially when it is constant like a Valor and not on/off like a furnace. In fact, too large a heat output will overheat your room. Many competitive brands promote large BTU input models playing the old "Bigger is Better" game. With a truly efficient zone heater, this is simply not the case.
All Valor heaters are designed with variable heat controls that you can turn down very low if required. You'd be surprised how many competitive brands can only be turned down a little or not at all. Valor's wide operating range and ease of adjustment allows you to match the Heat Output to the heat required providing maximum use and enjoyment. A big BTU fireplace with limited turn down is just another furnace and will not provide a Comfort Zone.
The ValorStat is a new control feature available on selected Valor models. It automatically adjusts the burning rate to match the heat requirement of the room. You select the temperature level you desire on the conveniently located dial and the heater regulates itself, burning as low or high as needed to keep an even room temperature. By contrast, conventional thermostats regulate heat by turning burners on and off rather than up or down. This results in fluctuating room temperatures and a fire effect that is unnatural and erratic to say the least. The ValorStat feature is exclusive on Valor.
From the warming rays of the sun to the embers of a hot open fire or glowing stove, people have enjoyed the soothing sensation of radiant heat since the beginning of time. Valor fireplaces are designed to provide the maximum amount of forward focussed radiant heat, up to 40% of total heater output. By comparison, a central warm air furnace delivers no radiant heat. Besides the superior feel of the heat, advantages of radiant heat include - faster heat, warmer floors, walls, and furniture. It is also quieter as there is no fan running. You will also feel more comfortable at lower room air temperature settings, providing further opportunity for energy savings.
Valor fireplace heaters are so effective at producing both radiant and convected heat that a blower will not do a lot to improve your comfort. Blowers cannot deliver radiant heat nor will they influence air circulation much beyond the immediate area of the fireplace.
There are three types of fireplaces used for separate applications specific to each home. To learn more about each application click here.
To convert your wood-burning fireplace into gas, you must get an insert type gas fireplace. They are designed to fit into existing masonry and prefabricated fireplaces. For more information on our insert applications, click here.
