How a Furnace Works

Wednesday, November 23rd, 2011

Do you know how your furnace works? Believe it or not, lots of Harleysville homeowners probably can’t explain the operation of furnace. It probably isn’t at the top of your “to do” list. It’s only important to know that once you set your thermostat to a desired temperature, the furnace comes on and warms the house.

The most common furnace is fueled by natural gas but there are other examples of heating equipment such as boilers, electric baseboard, or geothermal. But let’s look at how a gas furnace works since natural gas is found in most U.S. households. Gas furnaces use natural gas or propane to provide energy used for generating heat.

When the temperature in your home falls below the level set on the thermostat, an electric pilot light automatically ignites to heat a burner inside the furnace. This burner uses gas to generate heat within a combustion chamber inside the furnace. After the furnace senses that the thermostat has triggered the flame and that it is properly lit, the actual spark (or ignitor) is turned off.

Simultaneously, a motor in the furnace pulls in air from an exchange or return, which could be a grill in the floor, ceiling, or wall of a house. That air flows through ducts into the plenum of the furnace. The plenum is on the opposite side of the heat exchanger from the burner.

Gas will typically burn for at least two minutes before the blower starts to disperse heat throughout your home. This extra time gives the air an adequate period of time to warm up and also so that cold air won’t be pushed through the vents into the rooms in your house at the start. After either the preset time (roughly two minutes) or pre-established temperature is reached, the blower’s motor is turned on and it blows air over the heat exchanger, which usually consists of a series of copper tubes or pipes. When a fan blows air onto the heat exchanger, the air is heated. This heated air is then blown through a series of ducts to heat your home via vents in the floor, walls or ceiling. Exhaust fumes from the combustion process exit the furnace through a gas flue or chimney.

Just as the heat in your home turns on when a certain temperature is reached, it also turns off after the rooms are warm enough, thanks to your thermostat. The thermostat again senses the temperature in the room. When the room warms up to the temperature set by you at the thermostat, the gas valve is switched off, stopping the flow of gas. After the gas is turned off, the blower motor will still run for a few minutes, allowing the heat exchanger to cool off a bit. In some furnaces, the blower motor never shuts off, but operates at low speed to keep air circulating throughout your home.

In a nutshell, your thermostat is the brain in your heating system and your furnace is the brawn, doing most of the work.

Make Your Heating System More Energy Efficient

Wednesday, November 16th, 2011

Efficiency is what you want when it comes to heating your Abington home. You want a furnace that provides the greatest degree of accurate indoor comfort while at the same time operating at peak efficiency to reduce energy usage and lower utility bills. That’s seems like a lot to ask of a simple mechanical system but you should expect it out of the furnace in your basement, attic, or mechanical room.

It is especially important today as energy costs have steadily increased, including electricity, natural and propane gas, and oil. The best way to combat rising prices is to have a furnace that uses less energy. It is a simple statement but one that bears repeating: higher efficiency equals lower operating costs.

Here are some ways to make your heating system more energy efficient:

  1. Clean or replace furnace filters on a regular basis. A dirty or clogged filter will make your furnace work harder and become much less energy efficient. Monthly or quarterly cleaning or replacements are easy to do and will result greater operating efficiencies.
  2. Inspect your home’s ventilation system for accumulation of dirt, dust, or debris. Have you recently added new carpeting? Do your pets shed? Is there a large number of people living in your home? If you answered yes to any of these questions you may need to inspect your ventilation system.
  3. Remove obstructions from around vents and grilles. You need a clean path for air to flow into and out of rooms. Restricted airflow makes your furnace work harder and become less energy efficient.
  4. Consider an upgrade to a two-speed or variable speed furnace. Most older furnaces operated on one speed, which cycled on and off and consumed a lot of energy. Today’s furnaces operate at lower speeds, consuming less energy and often remaining on to keep a steady airflow and prevent constant on and off cycling. These newer furnaces are much more energy efficient and cost less to operate.
  5. Adhere to a regular schedule of planned furnace maintenance. If you don’t clean and inspect your furnace on a regular basis, schedule service calls with a local qualified heating contractor. Your contractor will likely have a service agreement plan to fit your budget, which allows for annual inspections, priority emergency service calls, and discounts on parts and services.

Besides saving on energy costs, your efficient furnace will leave a smaller “carbon footprint.” Your efficient furnace will exhaust less carbon dioxide into the atmosphere and maintain a more “green” profile. And being ecologically friendly can be just as important as saving money.

You can be assured that an energy efficient heating system will keep more money in your pocket this fall and winter.

What to Look For When You Have Water Damage: A Tip From Willow Grove

Wednesday, October 5th, 2011

Water can be a beautiful thing. But it can be a very nasty thing, too. While water is an essential for life, it brings a high price tag when gone unchecked and allowed to seep, leak, and drain into your Willow Grove home. Damage caused by water can cause structural damage to a building and destruction of its contents. When left unchecked – over time – water damage can lead to mold growth and have a serious affect on building occupants’ health.

The destructive forces of water leave telltale signs throughout a building. Let’s look at some.

  • Wood damage – water can saturate wood, causing it to rot and decay. Check for discolored wood around plumbing fixtures, a sure sign of an ongoing or older leak that has since been repaired. Just because a leak has been fixed, the after-effects can linger. Soft or uneven surfaces around a plumbing fixture are a sure indication of water damage. Pull back carpeting, pads, tiling, or flooring to get to the root of the problem.
  • Drywall damage – porous material like drywall can leave many signs of water damage and, like wood, can be seriously degraded by water damage. Check for discoloration around plumbing fixtures and soft spots. Don’t assume that a dry surface that is stained is not a structural problem. You may have to cut out the drywall to reach the true source of the water damage.
  • Ceiling tile stains – a sure sign that water is coming in from a source above a roof or ceiling. Ceiling tiles are a porous material that are great for showing every little bit of moisture or water that comes in contact with them. The same is true with plaster or drywall ceilings. Stains indicate a more serious problem and should be investigated right away.
  • Damp, musty smells – water can leave some unpleasant odors, especially untreated water. Leaks or standing water are a source for higher humidity levels in a home. If you are standing in an area where water has soaked into floors or walls, there is often a damp, humid smell. Don’t mistake it for high humidity levels in the home. The smell can come from hidden sources like a leaking pipe joint or broken valve behind an access door.
  • Mold build-up – wood and drywall surfaces provide great food for mold growth when saturated with water. The mold can be of a harmless nature but often can become dangerous black mold. When black mold spores are airborne they can cause respiratory problems and even worse, medial problems down the road. Look for unusual clusters of mold in damp areas and if you find some, immediately call a professional plumber to suggest clean-up and to repair the source of the water leak.

There are many signs of water leakage in the home, caused by leaking or broken pipes, dripping faucets from worn-out washers, cracks in the walls and foundations allowing ground and rain water to seep in, etc. Find and fix the source immediately or pay even higher costs in repairs later on.
