Home Performance Financing 101

Friday, February 6th, 2015

Is all this talk about Energy Upgrades and Home Performance getting you down because you’d love to make improvements to your home, but lack the finances to make it happen?

Believe it or not, we were in  the same boat (even though we both work in the industry). We were aware of the enormous benefits of a weatherized, insulated, and efficiently heated home for years before we finally pulled the trigger. I always just assumed we couldn’t afford it! I was completely in the dark about just how many financing options were available. That’s our home in the photo above, being tested for all things Home Performance related. That very home is now fully sealed/weatherized/efficiently heated/ventilated/basically every upgrade we could think of, for just under $100/month with the financing we received!

What types of financing are available and how to begin?

There are 4 basic types of financing for Energy/Home Performance/Heating upgrades.

  1. Energy Upgrade-Specific Financing: This is probably your best bet if you qualify, and it is the route we went for financing. Check out Puget Sound Cooperative Credit Union’s ENERGY SMART loans. PSCCU is a co-op bank geared toward local, environmental, and energy-savings solutions. And, they have fantastic rates! Must be in WA State to work with them, but check with your local financial institutions to see if your state has a similar program.
  2. A traditional Home Improvement Loan. This will likely be a little more expensive, but still a great option, and usually a better rate than a personal loan. Check with your current bank for their home improvement financing options.
  3. Personal Loan. Again, check with the bank you already do business with. A lot of times, you’ll get your best rate there, because they know you and want to keep your business. Personal loans tend to be a little more costly than other types of loans.
  4. Larger HVAC and Home Performance companies oftentimes have banks they work with, and you can receive significant deals, discounts, and lower rates by going through them. If you live in our area (Whatcom, Skagit, Island, San Juan, and Snohomish counties), check out Barron’s financing. We make available a 7.5% 10 year loan through a local bank, and a 6 mo. same-as-cash deal (if you qualify) through a nation-wide bank. Check with your local HVAC company to see if they have similar programs.
  5. Your local Human Services Organization (Bonus option!), though this is less about financing and more about low-income options. Some folks can receive free or very low-cost Home Performance/Weatherization work through the Human Services organization in their area. Our local agency is the Opportunity Council.

What’s Your Return On Investment (ROI)?

Here’s the nitty-gritty. If you’re ready to make the leap with financing, you’re probably asking just how long will it take to break even (between what you’re paying each month and what you’re saving in energy bills)? The basic formula goes like this:

Total cost of the project (divided by) your estimated annual savings = ROI

For simplicity’s sake, let’s say your project costs $10,000 and that allows you to save $1,000 per year in energy bills. Your ROI will occur in 10 years.

Where does one get these numbers? Your HVAC or Home Performance expert can give them to you.

What About Rebates?

The three main rebate programs for energy upgrades and home performance in our area are through Puget Sound Energy (PSE), Cascade Natural Gas (CNG), and the Community Energy Challenge (CEC). Here are direct links to the Applications for Homeowners: PSE Rebates , CNG Rebates, and CEC Information.

Beyond Finances:

Although finances are of primary importance for most people, there ARE other significant benefits to consider beyond the money saved.

  1. Peace of Mind: A new heating/cooling system and weatherization can set your mind at ease; allowing your family to relax without having to worry about shut-downs and repair costs.
  2. Health & Safety: There is ample evidence that people’s HVAC equipment and home are making them sick. An out-of-date, improperly-installed, or inefficient system can be very unhealthy, causing or contributing to myriad health-issues and diseases. And safety issues, such as carbon-monoxide leaks can be an immediate danger.
  3. Comfort: Most people want to create a warm, cozy, comfortable space for their friends and family. This is an undeniable benefit of investing in your home!

If this article has piqued your interest, I hope you will take a minute to contact your bank or HVAC contractor to get the ball rolling! You might be surprised by how affordable it is to create a cozy, efficient, healthy space!

Understanding Efficiency Ratings of Furnaces

Thursday, July 18th, 2013

A central furnace or boiler’s efficiency is measured by annual fuel utilization efficiency (AFUE). The Federal Trade Commission requires new furnaces or boilers to display their AFUE so consumers can compare heating efficiencies of various models. AFUE is a measure of how efficient the appliance is in the energy in its fuel over the course of a typical year.

Specifically, AFUE is the ratio of heat output of the furnace or boiler compared to the total energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere. AFUE doesn’t include the heat losses of the duct system or piping, which can be as much as 35% of the energy for output of the furnace when ducts are located in the attic.

An all-electric furnace or boiler has no flue loss through a chimney. The AFUE rating for an all-electric furnace or boiler is between 95% and 100%. The lower values are for units installed outdoors because they have greater jacket heat loss. However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric furnaces or boilers an uneconomic choice. If you are interested in electric heating, consider installing a heat pump system.

The minimum allowed AFUE rating for a non-condensing fossil-fueled, warm-air furnace is 78%; the minimum rating for a fossil-fueled boiler is 80%; and the minimum rating for a gas-fueled steam boiler is 75%. A condensing furnace or boiler condenses the water vapor produced in the combustion process and uses the heat from this condensation. The AFUE rating for a condensing unit can be much higher (by more than 10 percentage points) than a non-condensing furnace. Although condensing units cost more than non-condensing units, the condensing unit can save you money in fuel costs over the 15- to 20-year life of the unit, and is a particularly wise investment in cold climates.

You can identify and compare a system’s efficiency by not only its AFUE but also by its equipment features, listed below.

Old, low-efficiency heating systems:

  • Natural draft that creates a flow of combustion gases
  • Continuous pilot light
  • Heavy heat exchanger
  • 68%–72% AFUE

Mid-efficiency heating systems:

  • Exhaust fan controls the flow of combustion air and combustion gases more precisely
  • Electronic ignition (no pilot light)
  • Compact size and lighter weight to reduce cycling losses
  • Small-diameter flue pipe
  • 80%–83% AFUE

High-efficiency heating systems:

  • Condensing flue gases in a second heat exchanger for extra efficiency
  • Sealed combustion
  • 90%–97% AFUE

The 3 Fan Motor Types – ECM Unmasked

Friday, February 1st, 2013

It is not commonly known that there are 3 Fan Motor Types, nor is it commonly known to the consumer what the differences are. Below is a brief description of how the three differ and an extended article on the many benefits of the Variable Speed Fan Motor that was written by me previously. As always, thank you for reading.

The PSC Fan Motor. This is also known as the Standard Blower. It usually has around 4 speeds of which one will be selected for when the heat comes on based on the Delta T. The cost to operate this blower 24/7 is approximately $353 per year (based on 3 ton). It is often found in the Single and 2 Stage Furnace.

The X-13 Constant Torque Fan Motor. Also known as just the X-13 ECM or X-13 BOOST because it tends to increase the efficiency ratings of Heat Pumps in order to qualify for rebates. This too has around 4 speeds that will be tapped based on the Delta T, however, this motor will allow the installer to set up a CONSTANT FAN tap to ramp the blower down to 60% of its heating speed to give constant circulation at lower velocities. The cost to operate this blower 27/7 is approximately $120 per year (based on 3 ton). That is having your fan on 24/7, however, at during heating cycles this blower matches the efficiency of the Variable Speed ECM detailed below. This blower is also FAR more forgiving than the Variable when it comes to the existing duct design of different homes.

The Variable Speed ECM Fan Motor

One of the best descriptions is by Danny Heinman

“For any furnace, providing maximum comfort means achieving the proper amount of airflow. This is true for both heating and cooling operations. Unlike conventional single speed motors, a variable speed motor runs at a wide range of speeds. Using intelligent technology, it continually monitors incoming data from your heating and cooling system, and it automatically makes the adjustments necessary to meet your comfort needs. The motor varies the amount of air circulated, compensating for factors like dirty filters by increasing speed. Put simply, it delivers just the right amount of air necessary to provide the desired level of heating and cooling comfort.”

The variable speed motor is very diverse, but it has one flaw. NO speed taps. So if I put this blower into ducting that is designed poorly or has too much restriction, it will ramp up and up and up and up and then finally make you hate me! So, we are very picky about who gets these blowers, however, some duct issues are also easy to solve. That being said, because there are no taps, this motor ramps down to about 30% of its capacity to give you wonderful constant fan operation (see article below). The cost to operate this blower 27/7 is approximately $40 per year (based on 3 ton).

Below is part of an article I wrote about 3 years ago that still rings true.

DISCLAIMER – before running any fan 24/7 your ducts should be sealed. Read more about AeroSeal duct sealing. http://healthefficiencycomfort.blogspot.com/search/label/Duct%20Sealing

…We will start with the most important of the three, which may not be the one you would expect. It is your Health. There is an insane amount of data that will back up my claim, but all you need to know is that while you can see “dust” in the air and settled on surfaces, about 99% of the particles in the air are smaller than 1 micron (1 millionth of a meter). The human eye can only see particles bigger than 10 microns in size. So next time you are looking at all the dust in your air when the sun is shining in your window, think, “Wow, that is only 1%?!” and then call me.

How variable speed effects your health is really very simple. Tell me, what is your furnace doing when it is 68 degrees out side? That’s right, nothing. What is your filter doing while your furnace is doing nothing? More nothing. That is where variable speed comes in; when the furnace is not heating or cooling and the fan in is constant operation,variable speed furnace will continue to slowly and inexpensively circulate air throughout your home. This allows your filters to capture more contaminants (because air is constantly passing through them), so you can breathe easier.

From a Comfort stand point, variable is a god send. Literally, a gift to man sent from heaven. The hilarious thing is that it is just so simple. The element that it all boils down to is constant air flow, period. That is it. Most people do not turn on their fan 24/7 because they believe it will cost them a lot of money (on a standard blower they are correct) and more often than not, it is just too loud. What variable blowers do is ramp the blower down so you do not notice it running, nor does it cost you any more money than standard furnace operation.

Sorry, back to Comfort. Here is what variable speed will do by providing constant air flow. The greatest thing is the even heating and cooling you get. Instead of having the upstairs hot and downstairs cold, variable combines those two environments to create an equal and balanced air temperature. When I turn off my fan in my home the upstairs will generally be about 7-8 degrees warmer than my downstairs; once I turn it back on, the spread becomes 1 degree if not the same! It also solves the age old issue of Cold Blow. This is the burst of cold air that comes from the ducts before the hot air gets to you, just like the cold water at your faucet. Well, just like plumbers have circulation pumps that keep hot water in the pipes at all times so when you turn on the faucet you just get hot water, we do the same thing with variable speed. When the furnace turns on, the ducts are already tempered with warm air flowing through them constantly, so you do not feel that blast of cold air in between heating cycles!

Next is Savings. Not only is the blower itself more efficient at about 8-10x that of a standard blower, but it makes everything it is attached to more efficient as well. You will consistently get better efficiency ratings on heat pumps and air conditioners that are attached to a variable speed system. Not only that, your furnace will operate better and your filters work harder for you.

Perhaps the most abstract, but exciting, feature that variable speed offers is the use of latent BTUs to evenly heat your home. When you touch a light bulb it is hot, your audio/video system is hot, your refrigerator pumps out heat like crazy, and you emit 400 BTUs per hour yourself, not to mention Solar heat gain! Just think if there was a way to take all that heat being generated and distribute it all throughout the house, creating less need for your heating system to turn on! Of course, you know the answer.
