You’ve decided the time has come to replace your ancient, unreliable furnace. Good planning! The deepest cold hasn’t yet arrived, but it’ll soon be on its way. That gives you enough time to replace your old furnace with a new one that should give you many warm winters.

However, getting a new furnace isn’t as easy as shopping for furniture or purchasing appliances online. You can’t simply look at a furnace model and say, “Yeah, I’ll get this.” Furnaces have special requirements, and there are a few important points to know about installation.

Heating Installation Question: What Makes a Furnace High Efficiency?

Wednesday, February 1st, 2012

You’ve probably heard about the new lines of high efficiency furnaces being released by popular home heating companies in Garrett Park, but what exactly is different about these high efficiency devices from your current furnace? Let’s take a closer look at what a high efficiency furnace offers and why it can save you money.

Added Features

A high efficiency furnace uses familiar technology in a new way to reduce the amount of energy lost when combustion takes place. This means:

  • Sealed Combustion – Instead of open combustion which allows heat to escape during and after the combustion process, a high efficiency furnace uses a sealed chamber with carefully measured and fed airflow to burn fuel and produce heat. Exhaust heat can then be recaptured and used to heat air transferred to your air vents.
  • Two Stage Gas Valves – With a two stage gas valve, your furnace can respond to the temperature outside. There isn’t just one “on” switch. The furnace will regulate gas flow based on how much energy is needed to produce heat for your home. So, if there is a sudden burst of cold outside, the furnace will respond accordingly, but for most days when heating needs are low, it will use only the minimum amount of needed gas.
  • Programmable – High efficiency furnaces are now programmable, meaning you can set specific time limits for operation, change thermostat settings digitally and inspect the device through an electronic read out. The level of control given to you by a programmable high efficiency furnace can greatly reduce gas or electricity consumption.

Cost Benefit

The real reason many people are interested in high efficiency furnaces is that they are so much less expensive to operate. Instead of costing hundreds of dollars to run through the winter, they operate the bare minimum needed to heat your Garrett Park home. Using up to 95% of the fuel they consume to produce heat and regulating gas to cut how much is consumed during milder days, these furnaces are built to save you money.

If you have an old furnace that chews through energy like nobody’s business, now might be the time to consider the benefits of a brand new, high efficiency model.

Heating Installation Question: What Is an Electric Furnace?

Friday, January 27th, 2012

There are many types of furnaces in Spencerville that use a variety of energy sources to operate. Gas furnaces use natural or propane gas, boilers and radiators use water, heated by electricity. And then there are electric furnaces, which may have an advantage over other energy sources based on energy costs.

Simply put, electric furnaces function through the use of electricity. They do not require the use of any type of fuel – but function through wires and chords. An electric furnace uses heating coils, sometimes referred to as “resistance calrods” to create heat directly in the air flow. Inside the furnace cabinet are controls, a blower, and the circuit breakers for the heating elements. Some furnaces have the breakers accessible from the outside of the cabinet.

Other add-on accessories may include an electronic air cleaner, air filter, humidifier, high performance media filter, and air conditioning evaporator coil.

The heating process begins with the home’s thermostat. A drop in temperature is sensed by the thermostat, which alerts the electric furnace. The coil then warms up, thanks to the electric current that passes through it. The heated coil in turn heats the temperature of the air around it, which is then blown into the house through a blower. The pressure that is exerted by the blower on the heated air, warms it further. The blower is able to overcome the resistance of the duct work and replace unheated, colder air with the heated air. In most homes there are various return air ducts that are used to bring in the colder air to the furnace. This cold air travels through the furnace, through an air filter, the blower, and finally through the heat exchanger. After this it will then be pushed back into the house as warm air.

To maintain a supply of fresh air in the house, some furnaces also suck air from the atmosphere outside. After the air in the house reaches a particular temperature, the thermostat automatically shuts off the electric furnace.

An electric furnace may be less costly to run, depending on the price of electricity versus other sources like natural gas, propane gas, or oil. Gas and oil are fossil fuels and burning them leaves a “carbon footprint” – the release of carbon compounds and gases into the atmosphere. An electric furnace does not burn fuel and thus does not leave a carbon footprint. This electric warming process results in fewer particulates and contaminants in the air, too.

Heating Installation Tip: Why AFUE Ratings Matter

Monday, January 23rd, 2012

When you are in the market for a new furnace for your Mount Airy home, there are several reasons you should pay attention to the annual fuel utilization efficiency (AFUE) rating. All newer model furnaces get an AFUE percentage, which measures how much fuel a particular model converts into heat. Furnaces with higher AFUE ratings are more efficient, but the size and type of furnace will also factor into how much you’ll save on energy costs.

Understanding the AFUE Ratio

The minimum AFUE rating for new furnaces is 78%. This means that seventy-eight percent of the fuel is turned into heat, and the remaining percentage is lost either through poor insulation, air leaks, or the ventilation system in the home. Because there’s no heat loss through a chimney flue, some all-electric furnaces can have an AFUE rating as high as 98%. However, if the cost of electricity used to meet your normal heating needs is higher than the efficiency savings, you may want to consider other options. Talk to a qualified HVAC contractor for advice about the most cost-efficient heater for your home.

Furnace Efficiency Features

Furnaces manufactured 15-20 years ago have significantly lower AFUE ratings (between 55%-70% for most older models) because they are typically single-stage, or single-speed systems. Single-stage furnaces are less efficient because they are designed to cycle on at full capacity and shut off when the desired temperature is met.  Newer, two-speed models have a second setting that runs consistently at a lower speed, which saves energy by burning less fuel. Multispeed furnaces that have variable-speed blowers are the most efficient because they operate at various levels and automatically adjust to the thermostat to maintain a constant temperature.

If you look at the AFUE ratings for multispeed and variable-speed furnaces, the ratios should be above 80%. Keep in mind that this only determines the efficiency levels for the furnace itself. You’ll need to factor in whether or not your home has proper insulation and other upgrades, such as double-paned windows and doors.

What is a Downflow vs. an Upflow Furnace?

Monday, November 7th, 2011

When you go looking to buy a furnace, you may well be surprised by how many different elements go into making a good purchasing decision. There are simply so many different kinds of furnaces available now and they each are more appropriate for certain situations. That means that finding the one that’s right for you is less about finding the one best unit than it is about finding the one that is the best match for your particular circumstances.

This applies to the type of fuel the furnace uses, its energy efficiency, and whether it’s an upflow furnace or a downflow furnace. Energy efficiency and fuel types are probably things that you’re more or less familiar with. But what are we talking about when we classify a furnace as an upflow or downflow model?

Well, it’s pretty much what it sounds like. These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.

While this is all very exciting, it may still not be obvious what impact this will have on your decision about what type of furnace to buy. The main thing you’ll have to think about when you’re deciding between an upflow and a downflow furnace is where the furnace will be placed in your house.

An upflow furnace is generally installed in the basement so that the heated air is directed towards the parts of the house you want cooled and so that the furnace can be appropriately vented outside of the house. On the other hand, a downflow furnace would be installed in your attic for the same reasons.

So where you want to have the furnace installed is probably the biggest thing to take into account as you’re comparing these two types of equipment. Of course, whether you pick an upflow or a downflow furnace, you’ll still have to select the appropriate AFUE, size and fuel source to best meet your needs. But making the choice between upflow and downflow can at least make it easier to narrow down your options. To make the right decision for your home, contact your heating contractor.
