Pros & Cons of Heat Pumps: A Guide from Bonney Lake

Wednesday, November 9th, 2011

When deciding on any major purchase in Bonney Lake, a critical step is to weigh the pros and cons. This helps you to decide on the best option and reach the best decision for your needs and preferences.

Installing a new heating system is a perfect example of a situation in which you would need to weigh pros and cons. There are a lot of options, and not all of them are right for all people. Take heat pumps, for example. They are great devices and serve many people extremely well as home heating solutions, but they are not without their drawbacks. Below are some of the pros and cons of heat pumps to help you decide whether a heat pumps if the way to go for you.

Pros:

  1. Inclusive – A heat pump not only heats your home in the winter but also cools it in the summer, thanks to a reversing valve that changes the flow of the refrigerant. Having one appliance for both heating and cooling can be very convenient.
  2. Energy efficient – Heat pumps are extraordinarily efficient when it comes to energy use. Because they simply move and distribute heat, rather than producing any on their own, they use minimal electricity.
  3. Simple – Operating on the same basic principles as your refrigerator or an air conditioner, heat pumps are relatively simple. More importantly, they simplify your life by putting your heating and cooling solutions in one package and running on electricity, so you don’t need any other fuels on hand.
  4. Inexpensive to operate – In addition to being energy efficient – which lowers your monthly energy bills – many heat pumps are eligible for federal tax credit. You can save a bundle by using a heat pump.

Cons:

  1. May need supplementing in cold climates – In climates where winter temperatures stay below 30 degrees Fahrenheit for a while at a stretch, a heat pump will have trouble keeping up and need to be supplemented.
  2. Don’t work in power outage – Obviously, because they are powered by electricity, a heat pump won’t work in a power outage, unlike some other heating solutions that do not require electricity.

Although the pros clearly outweigh the cons here, the cons are important as well. Carefully consider all these factors and more while deciding whether a heat pump is the solution for you.

What Happens if My Heat Pump Loses Power? A Question from Edgewood

Monday, November 7th, 2011

One of the advantages of having a heat pump in your Edgewood home is that they operate on electricity, so you don’t need to worry about having maintaining a supply of fuel to keep yours running. Where a furnace or boiler might call for you to purchase supplies of oil or natural gas, and a wood stove means keeping potentially messy firewood around, a heat pump runs cleanly on electricity.

Heat pumps are good at using electricity, too. They are often able to produce heat energy that can be as much as three times the electricity they draw to produce it. This means not just convenience, but also a big savings, just by virtue of using electrical power.

The risk there, of course, is that if and when the power goes out, so does the heat pump. That means when a big winter storm drops a tree on the local power line, things can get cold inside mighty quickly. For these situations, you should have a backup heating solution on hand to keep everyone comfortable in the short term. And, as a responsible homeowner, you likely already have this taken care of.

But what happens when the power comes back on? Can you just fire your heat pump right back up without missing a beat?

The short answer is “no.” You should not do that, for at least two reasons. First of all, after any power outage, you should always take care to turn on appliances gradually over a period of time rather than all at once in order to avoid a spike in demand at the power company, which can blow a grid. That’s just a general tip.

Specific to heat pumps, though, there is a unique concern. If the heat pump loses power for more than 30 minutes, the refrigerant can get too cold to flow properly, so turning it right back on can cause the whole thing to conk right out. Instead, do the following:

  1. Make sure the heat pump is off. You can do this during the power outage.
  2. Once power comes back on, turn the heat pump to the “Emergency Heat” setting. This will allow the compressor to warm up slowly and get the refrigerant warm enough to start flow freely again.
  3. Wait. The time you need to wait varies depending on the size and manufacturer of your heat pump, so refer to the manual. In general, you should wait at least 6 hours.

After this process, your heat pump should be ready to resume normal operation without issue.

Heat Pump Maintenance: Some Pointers from Seatac

Friday, November 4th, 2011

Heating and cooling your Seatac home is a priority. You need your home and family to be comfortable all year round, so you either got or are considering a heat pump. These machines are great because under the right circumstances, they are essentially all-inclusive and incredibly efficient solutions for all your home heating and cooling needs.

Notice the “under the right circumstances” part. A number of things have to be considered when choosing a heat pump, such as the climate and the size of your home. But these are not the only circumstances that influence how well your heat pump works for you. Proper maintenance is a vital component of heat pump ownership, ensuring that you get the best performance out of your heat pump for the longest time possible.

A major part of properly maintaining any machine is to keep it clean. A heat pump is no exception. Dirt and dust can affect the efficiency of your heat pump, as well as speed up corrosion problems. Keep the compressor and coils clean. Check them monthly or so and remove any accumulated dirt. Also, consistently check and change filters according to the manufacturer’s recommendations.

Simple cleaning is an easy and effective first step to heat pump maintenance, but there are some things that you just won’t be able to do on your own. For more intensive maintenance, it is best to call in a professional for an annual inspection.

During a routine maintenance check of your heat pump, a technician will inspect the whole heat pump system for problems. He will clean the compressor and coils, tighten any connections that may have loosened up and change the filters as needed. In addition, a skilled technician will be able to detect any early signs of trouble and make necessary repairs to prevent break downs. These small repairs can prevent big problems later on, thereby preventing some serious discomfort and a possible big expense.

If you are considering a heat pump as a heating and cooling solution for your home, great. If you have already decided on one and had it installed, congratulations on making a smart decision. Now, make another smart decision to protect that investment by keeping your new heat pump properly maintained.

What is the Emergency Setting on My Heat Pump? A Question from Lacey

Wednesday, November 2nd, 2011

While installing or inspecting your Lacey home’s heat pump, you may have noticed that little switch or button labeled something like “Emergency Mode.” And then, you probably scratched your head and thought, “what is that for?”

Hopefully, the emergency setting is not something you will ever have to use. But, it is there for a reason, so it’s possible you may have to resort to it at some point. In that case, it makes sense to know what it is first.

The emergency setting on your heat pump interrupts the normal operation of the device. The compressor shuts off, so the heat pump no longer pumps heat from the outside into the home. Instead, the internal heating element is activated. This backup system is designed to provide a sufficient, albeit minimal, amount of heat when the heat pump is not working properly. The idea is that the element can keep your home warm enough while you get the heat pump fixed.

That’s what the emergency setting is, but when would you use it?

It’s not a trick question. As the name implies, you only want to use this setting in an emergency. For example, if the heat pump has frozen and isn’t operating, the best course of action is to switch on the emergency mode and call a professional to repair it.

You would also want to use the emergency mode when recovering from a power outage. Any time a heat pump is without power for more than thirty minutes the refrigerant can cool and get too thick to properly flow through the coils. Turning the pump back on in this situation can damage it, so instead you would use the emergency mode for a while to warm the refrigerant back up, then return to operating the heat pump normally.

The emergency setting is not to be used in place of a supplemental heating system. If there is an uncharacteristic cold snap, and your heat pump can’t keep up, then it makes sense to use the emergency setting to keep the house warm. However, if you live in a colder northern climate, where temperatures routinely drop below 30 degrees in the winter, you should have a supplemental heating system in addition to the heat pump. Using the emergency heat setting regularly is not a good idea.

How to Get the Best Heat Pump in Tukwila

Friday, October 28th, 2011

Happy Halloween weekend from everyone at Sound Heating & Air Conditioning! We hope you have a fantastically spooky time! But buying a heat pump shouldn’t be scary, even around Halloween. Here are some tips on how to choose the right heat pump for your Tukwila home.

But how do you decide what the best option is, especially when choosing a product that you know little about, like a heat pump? The average homeowner does not spend a lot of time studying his heat pump or reading heat pump magazines for fun, so chances are you are not a heat pump expert. That’s understandable…but it doesn’t help you when you are trying to buy a new one and you want the best.

Fortunately, there some things you can look for to get clues about the quality of a heat pump and how well it suits your needs. Read on to learn more about these indicators in brief.

Efficiency is among the most important factors in choosing a heat pump. Because heat pumps can be used for both heating and cooling, they have two different efficiency ratings, one for each mode.

The heating efficiency for a heat pump is rated on a scale called the heating season performance factor (HSPF). This rating is actually the result of a calculation. To find the HSPF for a heat pump, the unit’s estimated heating output is divided by its energy consumption. Simply put, it’s the ratio of heat put out by the unit to the amount of power it draws. The higher the HSPF, the more efficient the heat pump is. To give a frame of reference, all new heat pumps are required to have an HSPF of at least 7.7. The most efficient units available carry an HSPF of 10.

The rating system used to convey the cooling efficiency of a heat pump is the seasonal energy efficiency ratio (SEER). This is a simple numeric value that rates how efficient the unit is. Many new heat pumps carry a SEER of at least 12, while the most efficient models rate between 14 and 18.

While efficiency is important, it is just one factor. More efficient units are also more expensive, so you will want to consider the upfront cost. The most efficient units will pay for themselves in savings relatively quickly, but the purchase price is still important. Be sure to weigh all the pros and cons when choosing a new heat pump. And if you have any questions, talk to your local contractor.

What Is a Water Source Heat Pump?

Monday, April 25th, 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.

Is a Heat Pump Right for Your Home?

Monday, April 18th, 2011

Deciding which type of home comfort system to go with can be a difficult process to navigate. There are a ton of factors to take into account including how much you will be using the system, what type of fuel you mainly rely on and what the specific climate is like where you live.

Heat pumps are a great home comfort solution for many people but they aren’t always the appropriate choice. However, there are many benefits to going with a heat pump system, so this is certainly an option you should keep in mind as you evaluate your options.

Heat pumps work by extracting heat from the air in one place and then transferring that heat to another space. For instance, in the winter, heat pumps take heat from the outside air and pump it into your house. In the summer, on the other hand, your heat pump will be able to take heat from your indoor air and pump it back outside, thereby keeping your home cool and comfortable.

Heat pumps are also extremely energy efficient because they don’t actually have to generate the heat they pump. Unlike furnaces, which take in fuel and convert it into heat, heat pumps simply harness the heat that’s already there, making them by far the more energy efficient option.

Another benefit to heat pumps is that they maintain a more constant temperature than many other types of heating systems do. Rather than pumping in a big blast of hot air and then waiting until the temperature indoors falls below a preset level before doing it again, heat pumps provide a relatively constant stream of warm air.

The initial amount of heat is smaller than what you might be used to from a furnace, but the cumulative effect means that you’ll be able to enjoy a much more consistently comfortable indoor environment.

It is important to evaluate the climate in your area before you decide to purchase a heat pump, though. These systems are extremely effective at heating and cooling your home as long as temperatures stay above the mid-thirties.

Below that, you may need to install some type of supplemental heating in order to keep your home warm enough on those really cold days. So if you live in an area where temperatures routinely dip below freezing for large portions of the winter, a heat pump might not be the most sensible solution for you.

If I Choose a Heat Pump System, Will I Also Need to Install Supplemental Heat?

Friday, April 15th, 2011

Most Commonly Asked Questions about Heat Pumps

If you’re thinking about buying a new heat pump for your home, chances are you have some questions about these types of products and how they work. In fact, because these types of home comfort systems are relatively new to a lot of people, there are a quite a few misconceptions out there about how effective and efficient they can be.

Recently we’ve gotten some good questions from our readers, so we thought we’d like to pass along the answers so that others can benefit from the information as well.

If I Buy a Heat Pump, Do I Have to Buy an Air Conditioner Too?

That heat pumps are only able to heat your home is probably one of the biggest misconceptions about this type of equipment. Heat pumps work by extracting heat from the air in one place and transferring it to another. That means that in the winter, your heat pump is able to heat your home by taking heat from the outdoor air and moving it inside.

However, in the summer, the heat pump is able to do the same thing only in reverse. When you switch on your heat pump’s cooling function, it will be able to take the heat out of your indoor air and transfer it outside. In this way, the same heat pump system can keep your home warm in the winter and cool in the summer without you needing to purchase an air conditioner or other supplemental comfort systems.

That depends on what the climate is like where you live and how warm you like to keep your home. In general, heat pumps can keep any home comfortable as long as the outdoor temperature is above 32°F or so. If the temperature outside drops below that, you may want to have some type of supplemental heating system just in case. However, a heat pump will still be able to provide some warmth at these lower temperatures and you may be able to keep yourself comfortable with a simple space heater or too.

Also, remember that these colder temperatures are most common at night when you would probably have turned your heat down anyway. As long as you live in a relatively moderate climate, heat pumps can do a great job of keeping your home comfortable all year long.
