Q: Can you give me the scoop on space heaters?
A: It's getting cold outside! And when the chill is in the air, we often need a little extra warmth throughout the house, which usually comes in the form of a small package we call a space heater.
Space heaters are very common all over the United States, but do we really understand them? First, it is what it says it is- a space heater- meaning it is designed to heat a small space, not the whole house.
Second, most space heaters use 1500 watts of energy to produce their heat (some units can set back to 900 or 1200 watts). This is important because all 1500 watt space heaters produce the same amount of heating BTUs. Whether the unit costs $30 or $250, 1500 watts cannot magically be turned into different BTUs.
Terms like 'radiant heat,' 'oil-filled heat,' 'infrared heat,' or 'Amish-made' are marketing terms only. they all use the same energy and provide the same amount of heating. And the usage on these heaters can add significantly to your electric bill- as much as $100 per month!
As an energy guy, my advice is to be mindful of your usage of space heaters.
If you are purchasing a space heater, it helps to understand the difference in models. There are basically two types of space heaters- infrared and oil-filled/radiant. Typically, infrared heaters get warm quicker and are better for focused heating. Oil-filled or radiant heaters take a longer time to produce heat, but may be better for larger, open rooms.
In either case, I recommend you get a unit that has a thermostat installed so you can control the temperature. I also recommend setting your home thermostats a few degrees lower, otherwise, you may be paying twice to heat your home.
Finally, if there is an issue of leaving the space heater on when the room is vacant, I suggest putting the unit on a timer for safety, or better yet- turning it off.

Q: Why does my bill go up when temperatures drop? I keep my thermostat set the same...
A: We get that question often. During extreme weather, your system works harder to heat your home. As temperatures drop, this makes your heating equipment run at maximum capacity- which means it's using more electricity. Therefore, in just a few days, extreme temperature can cause your bill to spike.
The same is true for when it's hot, and you're trying to cool your home. Another way to think of it? The greater the difference between the temperature outside and the temperature your thermostat is set at, the harder your heating and cooling system is working (and thus, the more electricity it is using to do so).

Q: If I get solar panels on my house, I can have power during outages, right?
A: The short answer is 'maybe.' By current electrical code, all renewable energy sources that are grid-tied-- tie back to Owen Electric's system through the meter-- must disconnect and shut down when a power outage occurs. This is a safety practice that ensures a system cannot backfeed to our lines and cause harm to our line workers or equipment. This means you would NOT have power at your house during an outage.
Of course, there is an exception to this rule, and that would be if you have a battery pack backup system in place or a whole house standby generator. In either of these instances, your solar panels would still be shut down, but your house would be running off your battery backup or your generator. In this case, you would have power during an outage for as long as your battery lasts or for as long as your generator had fuel.
Once power was restored, your system would automatically switch back to Owen Electric for your energy needs.

Q: My neighbor and I have similarly-sized houses, but his energy bill is way lower than mine. What's the difference, and why can't I compare the two?
A: Houses may be the same size (square footage), but no two families live the same way! How many people live in your home? How many refrigerators or freezers do you have? How many loads of laundry do you wash per week? How many showers are taken? What do you keep the thermostat set at?
As you can see, there are lots of differences in how we live, which means there can be a lot of differences in our electric bills. As a member-owned cooperative, we are interested in how YOU live in your home, as well as how we can help you save on your energy costs and make your home more comfortable.

Q: Why should I call Owen Electric before shopping for solar panels for my home?
A: Solar panels are a long-term investment- a 25-30 year investment. As a member-owned, not-for-profit utility, Owen Electric is here to serve you, our member. We are simply a free resource for information, and since we have had our own solar panels for several years, we have a really good idea of how they work in our neighborhood.
Also, unfortunately, all solar companies do not fully understand the net metering tariff in Kentucky (rules everyone must follow). We can help explain the ins and outs of how the tariff works.
The best place to start is our website, www.owenelectric.com, and click on 'Member Central' tab, then click the 'Solar 101' link. For more technical information, click 'Net Metering.' Here, you can find our net metering application and a copy of the tariff.
Finally, if you're interested in renewable energy but don't have thousands of dollars to invest, take a look at our Cooperative Solar program. For as little as $460, you can have easy, affordable renewable energy.

Q: What can I do in and around my attic to make my home more comfortable?
A: Your attic acts like a blanket over your home, so we want to be sure our "blanket" is warm and air sealed.
Today's building code calls for a minimum of R38 insulation in your attic. ENERGY STAR for our region suggests an R46. Maintaining either of these will help to ensure the heated or cooled air in your home stays in your home.
Also remember to air seal the top plate of your home (the ceiling). As we know, insulation is only part of the process. Finding and sealing all the holes that pernitrate the drywall is the second part of staying comfortable and efficient.
Finally, don't forget about ventilation- this will help remove heated air and moisture from the attic space. Building code calls for 1 ft. sq. of attic ventilation for every 300 ft. sq. of roof deck. You can achieve this through natural ventilation (soffit, eave and ridge vents) or through mechanical ventilation (vent fans).
If you are using mechanical ventilation, be sure to seal the top plate, as this may put negative pressure on the house and pull heated/cooled air through the attic.

Q: I live in a manufactured home- what are some energy efficiency improvements I can make?
A: Manufactured homes, like stick-built homes, have energy codes that must be met during the building process. These codes are based on the area in which the unit was built, not necessarily where it will sit.
Since these homes are built in a factory, then moved to their location, they can present a few challenges along the way.
The biggest issue we see with manufactured housing is that many come with an inefficient electric furnace as the heating source. We always recommend this to be upgraded to a heat pump system, saving the member up to 40 percent on their heating costs.
The next big issue we see is the ductwork. This is a common factor in stick-built homes as well. We suggest using mastic and UL-rated tapes to seal all ductwork. We really want to move air into the home, not the crawlspace, attic or any other unconditioned space.
Air sealing is also important- caulk or foam any penetration that goes through the floor, ceiling or walls (think plumbing, pipes and electrical wiring).
The other important seal is the marriage plate for a doublewide home. You may have to remove the trim board, but this area runs the entire length of the home, so it has the potential to be a large area of heat loss.
Finally, be sure the bottom board, or the underbelly, is in good repair. This will help protect the ductwork and flooring of the home.

Q: What is ENERGY STAR, and is it really worth paying more for an ENERGY STAR-rated appliance?
A: ENERGY STAR is a governmental rating that sets strict energy efficiency and environmental standards. For example, ENERGY STAR-certified homes use up to 30 percent less energy than a standard "code" built home.
ENERGY STAR appliances are up to 15 percent more efficient than standard models, and rated lighting provides you with up to 65 percent savings!
All of this adds up to year after year of savings for you, the co-op member. And since you are saving on energy, you are also helping the environment.
While ENERGY STAR appliances do cost a few more dollars up front, they will save money over the lifetime of the product. Also, most rated appliances come with more features, making them more use friendly.

Q: Are heat pumps a good investment? And how does this compare to geothermal? How do I determine what to invest in?
A: Absolutely! When you compare a heat pump's efficiency (approximately 150-400%) to an electric furnace (100%) or a gas furnace (95-96%), it is easy to see they are good investments.
The big question is which heat pump is right for your needs. There are basically three types of heat pumps-
Geothermal is a ground source heat pump and is the most efficient way to heat and cool your home. These systems operate at approximately 400% efficiency.
Mini split heat pumps come as ductless or ducted models. These ductless models are a tad more efficient because there are no ducts, so there is no duct loss.
The more common air source split systems are what we see in most homes today. These units range in efficiencies anywhere from 150-200%.
As with any heating or cooling system, sizing is extremely important, so be sure to have your contractor perform a load calculation to get the right amount of BTUs needed.

Q: I've heard of a blower door test- what is it, and how will it help me save money on my energy bill?
A: A blower door test is one ay to help determine how efficient your home is. The blower door is a fan that depressurizes the house, thus allowing a technician to measure the amount of air leakage within it.
At times, the blower door is used in conjunction with an infrared camera to get a better visual of the air leakage. With the blower door test, we can find the exact amount of air leakage within the house AND pinpoint the big holes. This shows the homeowner where to start sealing the house- think windows, doors, sill plates, plumbing penetrations, etc.
For years, all states had code requirements for insulation levels, but only within the last few years have there been code requirements for air infiltration. We know that both insulation and air infiltration go hand in hand when making your home more efficient, more comfortable and healthier.

Q: If I'm planning to build, is there any reason to call Owen Electric before I start moving dirt?
A: Absolutely. When building a new home today, we need to think about the entire life of the home- approximately 50 years! And, we need to think about the comfort and operating costs of that home.
With Owen Electric's Touchstone Energy Home program, we incorporate guidelines that will save the homeowner up to 30 percent in utility costs compared to standard building codes.
We also take into consideration comfort and moisture issues, and can help with renewable energy sources if the member is interested.
Added insulation, air sealing, high efficiency HVAC equipment, and ENERGY STAR appliances are just a few of the items we discuss. And the best part? We offer a cash rebate when these incentives are met.

Q: What are the benefits of having a home energy audit performed? Are the suggested improvements going to be expensive?
A: There are many benefits of having a home energy audit. The first reason is peace of mind. Just how efficient and healthy is your home? Without testing and building science knowledge (how your house works as a system), you are really just guessing.
If you have any comfort issues (a hot or cold room), a home energy audit may provide details that are not seen with an untrained eye.
And what we think about most- money. What are you spending on heating and cooling costs? Is your HVAC system running at its designed load? What is the daily cost of living in your home? an energy audit can help answer all of these questions for you.
As for improvement costs, there are a lot of variables involved. But an energy audit usually can give you an idea of these costs and may be able to guide you to funding opportunities, such as rebates, tax incentives, qualifying programs, etc.

Q: How can I be as efficient as possible with a window air conditioner? How do I know what size to get?
A: As with all home appliances, ENERGY STAR is the way to go. When an appliance has an ENERGY STAR rating, it is 30 percent more efficient than the standard model. Over the life of the appliance, this can add up to substantial savings in energy costs.
When looking at window a/c unit options, you have multiple things to consider- size; noise level; energy savings options (sleep mode); ease of use (remote control); and fan only option, to name a few.
When it comes to sizing, most units are between 5,000 BTU and 14,000BTU. These will efficiently cool rooms between 150 and 700 square feet. These measurements can be found on the box or by an easy internet search.
As with most appliances, the more bells and whistles (ease of use items listed above), the more expensive it will be to purchase.
Another option to consider is the portable room air conditioner. There are multiple similarities with the window units, but installation is usually easier, and you can move the unit from room to room. The one negative aspect may be the floor space it takes up.

Q: How do I know when I need to replace the windows in my house, and what do I look for when I start shopping?
A: There are multiple reasons that you replace the windows in your home- aesthetics, sound proofing, and energy efficiency. If you're looking at aesthetics, beauty is in the eye of the beholder, and there are multiple designs to fit the most finicky buyer! Along with looking more modern, you should be able to recoup approximately 35-40 percent of the cost in resale value.
Sound proofing may be one of the most underrated advantages of newer windows. You'll be amazed at how well newer windows lower outside noise due to more efficient framing and more panes of glass.
Now, for those looking at energy efficiency... Today's energy code requires windows to be double pane, low E coated, with a U value of .35 or less (U value for windows is the equivalent of R value for insulation). The lower the U value, the more efficient the window.
I always suggest getting multiple bids when replacing windows, and I also strongly recommend that you consider weatherizing your current double pane windows. A tube of caulk goes a long way in keeping the drafts out of the house. Remember, air doesn't go through the glass- only the four corners where the window sits in the wall framing and along the rails where the window slides up and down.

Q: I'm looking to rent a home or apartment in a complex; what questions should I ask the landlord or manager to make sure I don't end up with high electric bills? Also, is there anything I can do to make a rented space more efficient, since I can't make any real physical upgrades or long-term investments?
A: When renting an apartment, I think you need to look at the things you can control verses the things you can't control. First, let's talk about those things you can't control- the physical structure and appliances. Knowing this, it may be a good idea to ask how old the apartment units are. Or have they been updated in recent years? The newer the unit, the newer the building codes, which should lead to more efficient insulation, windows, HVAC equipment, appliances, etc. Newly remodeled units could also provide these energy-saving features.
Now for the things you can control; first, start at the thermostat. We recommend a setting of 68 degrees for winter and 75 degrees for summer cooling. The HVAC fan should be left on 'auto.' Depending on the type of heating, for every one degree you lower the thermostat in winter, you can save up to 3 percent on our heating bill! Next, think about lighting. With LED bulbs so inexpensive, it makes sense to replace all lighting with LED units. Also, don't forget about phantom load. You know, all those cable boxes, gaming devices, laptops, phone chargers, etc. They all add up! The easy way to check this? Walk through your place at night- all those red and green lights are costing you money!

Q: I just received my stimulus check of $1,400 and would like to use it to make some energy efficiency improvements around my home. What can I do to get the most bang for my buck?
A: Spring is a time for home improvements and safety-- let's start with safety. If your current smoke/carbon monoxide detector is more than 10 years old, it's time for a replacement. The cost is approximately $100 for a new combination model; just be sure you have at least one on each floor of your home.
Next, let's look at the insulation in your attic. Current Kentucky building code calls for an R38, while ENERGY STAR recommends an R46. If you are on the low side of these, you can add an R19 for about $600 (blown fiberglass, 1500 square foot attic). Don't forget to check with Owen Electric to see if you qualify for the Button-Up program.
While we are insulating the home, how about doing a little air sealing around doors, windows, electrical wiring holes, water lines, etc. Basically anywhere there is a hole, you want to seal it. An entire case of caulk will cost around $50.
As the weather gets warmer, it's time to ensure your A/C system is correctly charged, cleaned and running at maximum efficiency. A system check will cost approximately $100.
Finally, since we know that domestic water heating is the second largest use of energy in the home, spend $5-$10 and insulate the hot water line.
With all this done, you still have a few dollars left to enjoy your favorite summer activity!

Q: I need to replace my water heater- what should I look for when I go shopping? Are tankless water heaters a good option?
A: Domestic water heating is the second highest use of energy in your home, behind space heating and cooling. With this in mind, it is important to look for a higher energy factor (EF) when choosing your standard tanked water heater.
Most tanked water heater models today are in the .94-.96 range. These come in 50-55 gallon models with a 6-12 year warranty. If possible, you will want to place your tanked water heater inside a conditioned space; this will improve efficiency and longevity.
While tanked water heaters are still the norm in today's housing market, tankless water heaters are growing in popularity. If you are interested in a tankless model, I would suggest going with a gas-fired unit- these will produce a higher gallons per minute (GPM) flow than an electric model.
Keep in mind there may be more maintenance issues with a tankless model, as it is essentially a furnace that runs water through it. As for cost savings, the tankless model will save you approximately $2 per month in "standby loss," or the amount of energy it takes to keep the water hot inside the tanked unit.
You may want to consider the total cost of installation as well- purchase cost; electrical upgrades to your home; maintenance costs; and upgrades to your cooperative's electrical system (transformer, conductor, etc.) before you purchase a tankless water heater.

Q: How often should I change my HVAC filter, and does it really make that big of a difference?
A: Forced air heating and cooling systems need adequate return air to work as designed and to offer the highest energy efficiency. How often you change the filter really depends on the filter you're using. Fiberglass models allow more air to pass through- along with contaminates- thus needing to be changed LESS often. Pleated filters catch more contaminates, but also suppress the amount of air flow, and thus need to be changed MORE often.
When looking at HVAC filters, the higher the MERV rating, the smaller particles it will filter. Things to consider would be:
-Are there pets in the home?
-Does anyone smoke?
-Does anyone have allergies?
-How airtight is the home?
-Is the ductwork in a conditioned or unconditioned space?
Obviously a lot of things to consider! Most manufacturers recommend changing the filter every 30 days, with the exception of high-end HEPA filters, but that is talking 30 days of RUN time. In late March, April, early May, late September, early October, your system doesn't run as much. During these times, if you're changing your filter every 60 days, you will be fine.
