No Heat in the House? Things to Check and Do

Wednesday, March 30th, 2011

In general, when your heating system stops working, you’ll need to call a professional to come out and take a look. However, before you do that, there are likely a couple of things you can check on your own to ensure that there really is a problem with the system itself.

For instance, if it’s cold in your house and your heat isn’t coming on, check to make sure that the thermostat is set to a high enough temperature that the heating system would be triggered. Particularly if this is the first really cold day of the season, it’s entirely possible that your thermostat was turned down at some point and left there. And if the thermostat isn’t turned up high enough, the heat will never come on.

Also, it’s worth just taking a second to check and make sure that the power switch on the heating system itself is actually in the proper on position. For the most part, there would be no reason for you to turn this off, but it’s always possible it could have happened in any number of ways and it only takes a second to check.

Depending on the type of fuel source your heating system uses, it’s probably a good idea to check to make sure the supply is still available as well. If you use natural gas, check to make sure that the gas line is open, but don’t try to repair it yourself if it seems to be compromised. If you find something like that, be sure to call your gas company right away.

However, if you use oil as a heat source, take a quick peek at the levels in your tank. There’s always the possibility that you used more than you thought you did or that a delivery was missed for some reason and so your heating system simply has no fuel to run on. Similarly, if your heating system runs on electricity, make sure that the fuse wasn’t blown or that it’s not just too loose to provide an adequate power supply.

If you’ve covered all of these basic troubleshooting bases, it may be time to take a closer look at the heating system itself. On just about every type of system there should be some type of reset switch or button. Follow the instructions to press this button and engage the reset process, but be sure to only try this once. If that resetting doesn’t work, it’s time to back off and call in some professional help.

What Is Forced Air Heating?

Monday, March 28th, 2011

Chances are that you’ve heard the term forced air heating before, particularly if you’re in the market for a new home heating system. But what does that actually mean? The truth is that if you’re asking this question, you’re not alone. There are so many types of home heating systems out there that it’s common to be a bit confused and overwhelmed by it all.

The truth is that a forced air heating system is simply a heating system that distributes heat throughout your house using air to carry it. In this type of system, heated air travels through a system of ducts and is expelled through vents into the different rooms and areas of your home in order to maintain a particular temperature. That temperature, of course, is whatever you set your thermostat to, and when the desired temperature is reached, the heat will shut off until the temperature drops down again.

The main difference between the different types of forced air heating systems is the type of equipment that heats the air. For instance, you could have a gas furnace, an electric furnace, a heat pump or a hydronic coil. All of these are capable of heating air, and when paired with a fan, blower or air handler, can distribute heated air throughout your home.

Many forced air heating systems are remarkably energy efficient and can effectively keep you home comfortable all winter long. Additionally, they are generally made to be incorporated with central air conditioning systems for year round temperature control. Heat pumps are especially convenient in this way, as they’re able to both heat and cool your home depending on the season and your home comfort needs.

Particularly if you already have ductwork in place or if you’re choosing a heating system for a new construction home, it can make a lot of sense to opt for some type of forced air heating. However, if you’re looking to replace an existing heating system in a house that doesn’t already have ductwork in place, the need to put it in can add a lot to the overall installation costs of the system.

Geothermal Myths

Friday, March 25th, 2011

As with any misunderstood technology, there are a lot of myths and misconceptions concerning geothermal heat pumps and how well they work. While these types of systems certainly have their limitations, the same is true of just about any type of heating and cooling system you could have installed in your home. But if you are really trying to evaluate whether or not a geothermal heating system is right for your home, you need to know exactly what is true about these systems and what is just not true.

For instance, there is a widely held belief that geothermal energy is not a viable heating option in areas with harsh winters. The fact is, though, that even when the air temperature outside is below freezing, the temperature several feet below ground can be as high as 55°F.

With a ground temperature like that, a geothermal heat pump will have no trouble extracting enough heat to keep your home comfortable even when it is well below freezing outside. And even when the ground freezes, the frost usually only extends three or four feet below the surface. Since the pipes for your geothermal heat pump will be at least four feet down, the frost should not affect them at all.

Also, it is common for people to assume that geothermal heat pumps will always need to have a regular heating system in place to serve as a backup. In fact, a geothermal heat pump is quite capable of providing consistent and adequate heating for your entire house as long as it is properly sized and installed. Make sure you are dealing with an experienced and qualified contractor and you will have no problems along these lines.

There are also plenty of myths floating around out there that geothermal heat pumps are just too expensive to make sense as a home heating solution. The truth is that geothermal heating costs almost nothing to operate.

While it is true the geothermal systems are quite a bit more expensive to install than many of the other options, alternative heating systems will still cost a significant amount to install and you will also have to pay much more to operate them on a regular basis. With a geothermal heating system, you pay quite a bit up front, but it is a one-time cost and there will be minimal monthly heating bills after that.

How Does Geothermal Energy Work?

Wednesday, March 23rd, 2011

Geothermal energy is energy extracted from the ground. This energy is in the ground in the first place because the ground absorbs the heat coming from the sun. This heat is always there, even when it is very cold outside. In fact, even when the ground appears to be frozen, you can actually extract plenty of heat to keep your home nice and toasty.

While this may at first appear to defy logic, the way that geothermal energy can be used for heating your home is actually quite simple. A geothermal heating system typically consists of an indoor air handler with a fan, a series of air ducts for the heated air to travel through and a closed loop of pipe that extends into the ground below and around your home.

This closed loop of pipe is actually where the geothermal heat is collected. Some type of liquid, usually water or antifreeze, will be continuously run through this pipe loop. As the liquid passes through the area of pipe that is below ground, it will absorb the heat from the surrounding soil. Once the liquid makes it back up to the air handler, the heat is able to disperse, heating the air in the chamber.

This heated air is then circulated throughout your house through the ducts by a fan. After it has released its heat into the air in your home, the liquid will cycle back into the ground to absorb more. This allows a geothermal heating system to provide you with a constant supply of warm air.

Unlike a furnace, which mixes in blasts of very hot air with periods of inactivity to try and keep your house at a constant temperature, a geothermal heat pump is able to provide a more consistent flow of air that is just the right temperature to keep your home comfortable. This means that these types of heat pumps are running just about all of the time as opposed to furnaces, but they are designed to work this way and the constant operation does not cause any excessive wear and tear.

Another great benefit of geothermal heat pumps is that they are able to keep your house cool in the summer as well. Just as the ground is warmer than the air in the winter, it is also cooler in the summer. That means that heat removed from your indoor air can be transferred to the ground in the same way that it was transferred in during the winter.

Is Geothermal Energy Renewable?

Monday, March 21st, 2011

Geothermal heating systems take heat from the ground and transfer it to your home. But how does this heat get into the ground in the first place? Conventional heating systems like furnaces use energy sources like oil or natural gas to generate heat. These energy sources are not renewable, and neither is electricity which is typically generated by burning coal or another non-renewable resource.

The renewable resources we usually think of first are solar and wind power. The sun, of course, will continue to shine and provide heat year in and year out whether we make use of it or not. Similarly, we cannot use up the wind. It will continue to blow no matter how many times it has blown before.

But what category does geothermal energy fit into exactly? Well, it is actually a renewable resource just like solar or wind energy. In fact, geothermal energy is a direct result of the sun’s heat relentlessly pounding the ground. The ground actually absorbs a considerable amount of the heat from the sun that reaches the earth every day, and that is the heat that your geothermal heating system is using to heat your home.

Of course, a geothermal heating system cannot run on geothermal energy alone. The indoor components of this heating system that keep the air flowing throughout your house must be powered by electricity. But the amount of energy needed to do this is much less than what you would need to use to run a furnace or other type of more conventional home heating system.

Over all, geothermal energy is an excellent and renewable source of energy. And once you have the heating system in place, you will need to spend very little to keep it up and running. It is an excellent option for many people, and can help to keep your home cool in the summer as well.

How Can I Stop My Toilet from Running?

Friday, March 18th, 2011

Nothing is more obnoxious than the constant tinkling sound of a running toilet. When your toilet starts pouring water through at a record rate, it is time to take a peek inside and make sure everything is working properly. Luckily, most of the time, a running toilet is very easy to fix. It may only be that the tank flap or the diaphragm needs adjustment. Here are some quick tips to help you diagnose and repair that running toilet and get back the peace and quiet of your bathroom once and for all.

  1. Going In – Open the tank of your toilet take a close look at the various parts. First, check the ball cock – the valve linked to the large plastic ball that floats on top of the water in your tank. If the noise is coming directly from the valve or you can see obvious issues, the ball cock likely needs to be replaced. Sometimes, it needs only basic cleaning, which you should do first before running out to buy a new part. It also possible that the tank flap is having issues. Look for a small cone in the hole at the base of the tank. Press down on it to see if the sound stops. If it does, the tank flap likely needs replacement.
  2. Turn off the Water Supply – Before doing any more, turn off your toilet’s water supply. Do not worry – you should not need to go hunting for the valve. It is most often located next to the toilet on the floor of your bathroom.
  3. Replacing Your Parts – When replacing any parts for a toilet, always remove the old part first and bring it with you to the hardware store. Almost all toilets have slightly different parts that may not match up universally. By having the part you need, you can give it to an expert in toilet repair and they can quickly find the right replacement.
  4. Careful Replacement – Most of the time, replacement simply involves unscrewing or removing the part and placing a new one in place. However, if you own a low flush toilet or a specialty design that does not have the same parts or layout of a traditional tank-based toilet, you may need the help of a professional to avoid any unwanted accidents or issues in the replacement process.

Ideally, the entire process should only take the better part of a couple hours, including the time it takes to go to the hardware store and purchase your replacement part.

How Can I Prevent Clogged Drains?

Wednesday, March 16th, 2011

One of the most frustrating plumbing issues any home owner will encounter is a clogged drain. Not only are clogged drains a nuisance, they are largely avoidable, so it becomes that much more frustrating when it happens since you know that you could have taken preventative measures long before the problem occurred. To help stop your drains from clogging in the future, here are some useful preventative tips:

  • Set Cooking Grease Aside – Cooking grease is thick, viscous and clings to the sides of almost all types of pipes. So, instead of pouring it down your sink and hoping it clears out on its own, pour it into a coffee can and set it aside. There are a number of places where you can recycle old grease.
  • Flush Garbage Disposals – When you use your garbage disposal, it is imperative that you flush cold water through the system at the same time. Without water to flush the food particles through the pipes, anything ground up in the disposal will become stuck and with the application of grease or other food particles can easily become a thick clog.
  • Pour Boiling Hot Water Down the Pipes – At least once a week it is a good idea to pour 2-3 quarts of boiling water down your sinks and bathtub to loosen any pre-clogs that have formed. Things like soap, grease, food, and hair can all be dislodged by an application of hot water on a regular basis.
  • Taking Care with Your Toilet – A toilet is not designed to flush anything that will technically fit down the hole. Even for paper products that seem to be flushable, take care in what goes into the toilet bowl. Paper towels, garbage, and wrappers should not be flushed or they are likely to cause clogs.
  • Use Strainers – Install strainers on all of your sinks, including the ones in your bathroom. A simple strainer will catch excess bits of food, hair, and other grime that has a habit of falling down the drain and getting flushed along with the dishwater or during a shower.

With care, your drains will remain clog free and never require the services of a snake or a plumber. If you do get past the point of no return, do not panic just yet – there are a number of steps you can take to remove a small clog without chemicals or professional help. However, if the clog refuses to budge or begins to backup, know when to call a plumber.

How Do I Stop My Pipes from Knocking?

Monday, March 14th, 2011

Tell me if this sounds familiar – you are sleeping comfortably and in the middle of the night a soft but persistent knock sounds through the pipes in your home. At first it is easy to ignore, but inevitably the sound will grow with each passing night and eventually start keeping you awake. Luckily, there are simple solutions for knocking pipes that do not require a plumber or expensive parts.

First, it is good to know why your pipes are knocking in the first place. In most cases, knocking pipes are caused by variable water pressure in the main supply pipes coming into your home. That pressure is important because it keeps the water moving freely between pipes and into your faucets. However, when the air used in pressurizing those pipes leaks or is depleted, water moves suddenly and violently, creating the knocking sound as it traverses the length of the supply lines.

The easiest fix for this kind of knocking is to first turn off your main supply valve. Make sure you communicate to anyone in your home that you are shutting off the valve as it will stop ALL water coming in. Now, flush the lines by opening all of the faucets and flushing your toilets. Water can still leave your home through drainage pipes and this will ensure all of the supply lines are fully empty.

Once the lines are cleared, feel free to turn your main valve back on. It is important to do this slowly so that the air chambers between and around your pipes have time to refill before the water courses back into them. However, now that the pipes were fully emptied, the knocking sound should be completely gone.

It is as simple as that. In most cases, you should not need to call a plumber to help, but if you have any problems finding your main valve or shutting it off, a plumber can be helpful with the proper tools and the know how for various kinds of shutoff valves. Additionally, if you live in an apartment building or a shared space, you may not be able to perform this fix. Rather, you should contact your superintendent or landlord and make sure they know exactly what is happening – with any experience, they should recognize the problem and be able to make similar fixes to your pipes.

Knocking pipes can be incredibly frustrating if not dealt with as soon as they start. Now that you know how simple it is to make the fix, make a habit of regularly flushing your lines and the knocking likely will not start up again.

It’s Time for a New Furnace

Friday, March 11th, 2011

Replacing your furnace is probably not something you want to think about. After all, a new furnace is a big investment and not something you probably have too much experience with. And sometimes having your current system fixed or tuned up is all you need to get your home heating situation back on track. But there are certain situations in which it makes more sense to just go ahead and get a new furnace rather than simply patching up the old one.

For instance, if you have to call for either minor or major repairs to your furnace on a regular basis, it’s probably time to consider investing in a replacement. All of those repairs cost money and chances are that the furnace you’re paying repeatedly to replace isn’t going to last that much longer anyway.

Rather than continuing to dump money into a furnace that just isn’t cutting it anymore, you’ll be better off making the investment in a new unit. The truth is, you’re going to have to do it sooner or later and by buying a new furnace now, you’re actually saving all of the money you would have spent on repairing the old one for another year or so.

Also, a furnace that requires such frequent repairs is probably not functioning all that efficiently either. When you replace it with a newer model, you won’t just save money on repairs. You’ll also likely notice a considerable savings on your monthly energy bills because of how much more efficient your new model is.

Even if you haven’t been repairing your furnace often, you may be able to notice some signs that the old unit isn’t quite up to the task anymore. If you’re suddenly having some significant humidity problems in your house or if your home isn’t being heated evenly, there’s a good chance your furnace is on its way out.

And, in fact, even if your furnace is functioning just fine but is more than 10 years old or so, it’s very likely you’d benefit by replacing it. That’s because the newer furnaces available now are so much more energy efficient than their predecessors that the savings you’ll incur monthly will quickly make up for the initial installation investment.

Of course, you don’t want to get rid of a good furnace if you don’t have to. But if your furnace is getting close to the end of its expected lifespan, you may very well benefit by putting out the money for a new one now so you can start saving right away on your monthly energy bills.

What Is a Water Source Heat Pump?

Wednesday, March 9th, 2011

A water source heat pump operates much like a traditional air source heat pump except that it extracts and dissipates heat by way of water instead of air. This is certainly not a type of home comfort system that will be available to anyone, but if you live in an area close to a well, lake or other natural water source, it may be an option worth considering.

All types of heat pumps can provide excellent year round home temperature control by pumping heat in during the winter months and removing it during the summer. The main difference between the types of heat pumps is where they get the heat or dispose of it.

Traditional air source heat pumps get their heat from the air outside, as even relatively cold air actually contains a substantial amount of heat. They use this heat to keep your house warm in the winter, but as the outside temperatures go down below freezing, these heat pumps can become less and less effective.

Water source heat pumps, on the other hand, work on basically the same principle as air source heat pumps, but they extract heat from a body of water rather than the air. They do this by cycling water through a system of pipes that is laid out at the bottom of a body of water. As the water cycles through, it gathers heat from the lake or reservoir and then carries it back to your house.

In the summer, the process is reversed and heat is carried out of your house and expelled in the cooler water outside. Like air source heat pumps, water source heat pumps are slightly more efficient at cooling rather than heating, as even deep water will eventually get cold during the winter months. However, the water is still often warmer than the air, and so water source heat pumps can be a good alternative if you live in a slightly cooler climate.

Of course, you do also need to have access to an appropriate body of water to have a water source heat pump installed, which makes it something that is not available to everyone. But if you do live near such a body of water, a water source heat pump is definitely something worth considering.
