Heat pumps move heat in and out of your home to provide efficient heating, cooling and humidity control. Air source units are the most widely used type of heat pump. They use the difference between indoor and outdoor air temperatures to heat and cool your home. Learn how air source units work and how they can benefit your home. How air source heat pumps work An air source heat pump system consists of a compressor and two coils made of copper or aluminum tubing; one coil is located indoors and the other one is located outdoors. In the winter, liquid refrigerant in the outdoor coil converts into a gas after absorbing heat from the air. In the indoor coil, heat is released from the gas refrigerant as it condenses back into liquid. How does cold air provide heat? Hot and cold are relative terms. All outside air down to absolute zero (-460°F) contains some heat. An air source heat pump extracts some of this heat and moves it indoors to provide space heating. In the summer, an air source heat pump simply works in reverse to provide highly efficient cooling. It takes heat from the warm indoor air and moves it outside. Split-ductless air source heat pumps — also called mini splits — don't require ductwork, making them perfect for additions or homes without ducts. Ductless systems include an outdoor unit and one to four indoor air handlers. Tubing that circulates refrigerant connects the indoor and outdoor units. The indoor air handlers are typically mounted on a wall or ceiling and are controlled remotely. Air source heat pump efficiency Air source heat pump heating efficiency is measured by heating seasonal performance factor — the total heating output of the unit during the heating season divided by the electricity consumed. The higher the HSPF, the more efficient the unit. ENERGY STAR®-qualified heat pumps must have a minimum HSPF of 8.5. Cooling efficiency for air source heat pumps is indicated by seasonal energy efficiency ratio (SEER) — the total amount of heat removed from the home during the cooling season divided by the energy used. Once again, a higher SEER is better. ENERGY STAR units must be rated at 15 SEER or higher. Air source heat pumps can reduce your energy use for heating by 50% compared to conventional technologies, such as furnaces and electric resistance heating. High-efficiency heat pumps also dehumidify better than standard central air conditioning systems, resulting in improved comfort and lower energy usage in the summer. Air source heat pumps work best in moderate climates with mild winters, though advances in technology have made them a good option for other areas, as well. If your heating or cooling system is older or you are considering an addition, an air source heat pump is a good choice for cost-effective year-round comfort.

How do electric vehicles provide clean, high-performance driving? Peek under the hood and find out! At first glance, electric vehicles may appear like conventional vehicles, but if you look closer, you’ll see a lot of differences. There is no fuel tank, oil pump or spark plugs. Also, EVs are powered by an electric motor instead of an internal combustion engine. Finally, EVs contain a lot of parts you won’t see on a conventional vehicle – such as a battery pack, charge port and inverter. Here’s how electric vehicles work: The charge port connects the vehicle to an external power source to charge the battery pack. The rectifier converts alternating-current (AC) voltage from the grid to direct-current (DC) voltage for charging the battery pack. The battery pack stores enough energy to travel a minimum of 100 miles per charge. The inverter takes DC voltage from the battery pack and converts it back to AC power for use in the motor. The motor uses electricity from the battery pack to create mechanical power to drive the vehicle’s wheels. Regenerative braking generates electricity while the vehicle is coming to a stop. This electricity is stored in the battery pack. EVs offer many advantages compared to conventional vehicles – lower fuel cost, less maintenance and quieter operation. Plus, EVs produce no tailpipe emissions. It’s no wonder EVs continue to gain traction! Ask us about rebates available for the installation of electric vehicle chargers for your home or business!

What are some simple ways to shift energy use to off-peak hours? Time-of-day or time-of-use pricing plans typically offer members lower rates during off-peak hours. The goal is to shift energy use away from peak hours — generally in the afternoon and early evening. Here are some simple ways you can save money by using less energy during peak hours. Adjust the thermostat to reduce heating and cooling energy use while away from home. Programmable thermostats optimize savings and convenience. Today's smart models add advanced features like remote control and self-programming. In summer, set the thermostat to 78°F when you're at home to reduce cooling energy use. A ceiling fan is a lower-energy alternative that can make you feel cooler. Remember to turn off fans when you leave a room. In winter, set the thermostat as low as 68°F, depending on your comfort level. Wear warmer clothing or use blankets to stay comfortable. Turn off lights in empty rooms and electronics when not in use. Plug electronic devices into advanced power strips or smart plugs, which automatically cut off power to unused devices. When cooking dinner, use lower energy options — such as a microwave, toaster oven or slow cooker — instead of the stove whenever possible. Only run the dishwasher on a full load and wait until after peak hours. Perform energy-using household chores — such as laundry and vacuuming — later in the evening or on weekends when electric demand is not peaking. Charge electric equipment — such as electric vehicles, lawnmowers and trimmers — overnight or on weekends.

Water and electricity don't mix. If you own a boat, follow these 6 safety tips. Unknowingly, many swimmers and boat operators place themselves in the face of danger by swimming near electric-powered boats and docks. This innocent act of fun can turn tragic as electric shock drowning occurs each year. Help prevent electric shock drowning or other electrical injuries with these tips from ESFI. Don’t allow anyone to swim near docks or boats. If you feel a tingle while swimming, the water may be electrified. Get out of the water as soon as possible avoiding the use of metal objects such as ladders. When your boat is docked, never use cords that are frayed or damaged or that have had the prongs removed or altered. Have ground fault circuit interrupters (GFCI) installed on your boat. Test them once a month. Consider having equipment leakage circuit interrupters (ELCI) installed on your boat to protect nearby swimmers from potential electricity leakage into water surrounding your boat. Have your boat’s electrical system inspected and upgraded by a certified marine electrician regularly. What is electrified water? When electricity touches water the electricity moves throughout the water. This results from flowing electrical currents from faulty wiring in or near boats or docks. The water molecules do not conduct electricity; however, the ions within the water carry the moving electrons throughout the water. These moving electrons create electrified water through a process called water electrification. What is electric shock drowning? Docks and boats can carry sources of electricity. Faulty wiring or the use of damaged electrical cords and other devices not approved as “shore or marine rated” can cause the surrounding water source to become energized from electricity leakage. When the human body makes contact with energized water it becomes the conductor of electricity and can cause complete loss of muscle control, ventricular fibrillation and electric shock death.

Does running a ceiling fan make a room cooler? Q: Does running a ceiling fan make a room cooler? A: Circulating air with fans doesn't cool a room; it makes people feel cooler by enhancing evaporation from the skin. Nearly everyone has enjoyed the relief of a cool breeze on a hot, humid day. The air movement created by circulating fans creates that same wind-chill effect, making you feel more comfortable — even in spaces cooled by air conditioning. This can reduce the need for climate control, lowering summer energy bills. Ceiling fans are particularly effective in circulating air. In some cases, running ceiling fans allows you to raise the thermostat by up to 4°F without a reduction in comfort. Running fans will actually waste energy if there is no one there to feel the effect. Therefore, it's important to shut off fans in empty rooms.

Both before and during the spring planting season, keep safety top of mind. In the rush to the field, it’s tempting to take shortcuts and sadly, much too easy to forget an important task or practice risky behavior. Observe these safety tips for a safer, less stressful planting season. Check All Equipment This is a task that can be done well in advance and is one of the most important. According to ISU Extension and Outreach, nearly half of all Iowa farm deaths result from working around equipment. Before heading to the field, check all equipment parts including safety guards, lights, hazard signs and any other necessary components. If you are planning to use a new or unfamiliar piece of equipment, read the safety details in the operator manual. Before moving equipment, especially if you will be on the road, lock down all moving parts, including hydraulics. Be Aware of Your Surroundings Before you begin planting, refresh your memory on any hazards present in each field. Also be aware of all utility lines and have a spotter check as you move equipment to ensure it will not accidentally come into contact with the line. If it does make contact, don’t leave your cab. Call your electric cooperative for assistance. When you are on the road, be aware of traffic ahead and behind you, as well as any vehicles coming toward you on the opposite side of the road. Use Extra Care When Working with Chemicals Anhydrous and other farm chemicals are dangerous, and exposure to various chemicals can cause severe burns, nausea, headaches and possibly even cancer. To protect yourself, wear long pants, a long-sleeved shirt, gloves, a mask and a hat and protective glasses. Follow the manufacturer’s instructions for the chemicals you use. Take Care of Yourself The rush of getting the field work done when the soil and weather are favorable can lead to working long, hard hours. It’s important that you get enough rest so you remain clear-headed and can cope with any dangerous situations that may arise. In addition, take stretch breaks, use ergonomics when lifting or performing any repetitive movements and take time to hydrate and eat.

Last month’s article about heat pumps pointed out the value of air-source heat pumps as a clean-energy source, their efficiency, the ease of use for both heating and cooling your home and that cold-climate units are now appropriate for Iowa homes. This month’s focus is on saving money when you install a heat pump. Here’s how: Any time you install a new HVAC system, it’s important to tighten up your home first so your new system will reach maximum potential. That task may include replenishing insulation, caulking and/or conducting an energy audit to determine if additional steps are needed. These actions can jump-start your path to saving on your utility bills. Recognize that because of their high efficiency, your heat pump will be more cost-effective than other heating systems in the long run. The savings will accumulate year after year. Check with us to learn more about rebates. At the same time, we can also provide more details on the process and answer your questions. Review federal tax credits. Beginning in 2023, there are Inflation Reduction Act federal tax incentives available of 30% of the total cost and labor (up to $2,000), in addition to $1,200 in tax credits for other energy-saving renovations and appliances. These additional credits are available for air sealing; home energy audits; and upgrading your electrical supply, if necessary, for the efficiency projects.

What do I do if a downed power line touches my vehicle? If a power line touches your car as a result of an accident while you are inside, don't get out. If possible, drive the vehicle away from the power line. There is no way of knowing whether or not a downed power line has been de-energized, so it's best to remain inside your vehicle until the local energy company advises you that it is safe to exit the vehicle. Use your cell phone to call for help or sound your horn to signal to others that you are in danger. If someone approaches trying to help, warn them to stay clear of the area and ask them to call the local energy company and emergency personnel. Even reaching out while inside the car and touching a conductive pole or metal door outside the car could cause an electric shock. It is not only the tires that protect you, but also the metal surrounding you. This is due to the “skin effect” or "Faraday cage effect," which means that electricity will travel only on the surface of enclosed metal objects. So, while your vehicle may be electrified, you're safe as long as you stay inside. If the risk of a fire forces you out of your vehicle, remove all loose clothing and other items and, with both feet together, jump away from the vehicle making sure that no part of your body touches the vehicle and the ground at the same time. Land with both feet as close together as possible, then shuffle (your feet in contact with each other and the ground at all times) as far away from the vehicle as you can.

All of the energy you spend each spring to create that perfect green lawn could be used to plant the seeds for a lower energy bill. A well-designed landscape can provide cooling shade around your home that reduces the need for air-conditioning. Dig this: Plant leafy trees on the south and west sides of your home to provide shade on hot summer days. The leaves will fall off in the autumn and allow warm summer sunlight to help heat your home during winter. Plant shrubs and ground cover around your house to help reduce heat buildup. Place evergreen trees on the north and northwest sides of your home to provide year-round windbreaks from outside air. Before you begin your landscaping project, call 811 to have underground utility lines marked. Knowing the location of underground utility lines on your property will help you avoid injury, service outages and costly repairs.

Q: Can You Use LED Bulbs in Enclosed Fixtures? A: You can if the bulb is rated for enclosed spaces. What is an enclosed space? It's any space where there is little or no air movement. Examples of enclosed light fixtures include those that have an acorn or other shape of glass shroud around the bulb and any surface-mounted or recessed fixture with a lens cover, such as can lights or fluorescent tube lamps. What's the issue with LEDs and enclosed spaces? LEDs are cool to the touch (unlike traditional bulbs) but they do generate heat. In fact, the base of an LED gets very hot and this heat is conducted into the surrounding air. High temperatures diminish the light output of standard LED bulbs and can shorten their lifespan. LEDs rated for enclosed spaces are augmented to perform well in warm environments. Be sure to look carefully on the package to make sure you have the right bulb for your enclosed fixture. With the right bulb in place, you can enjoy the many benefits of LEDs: lower energy use, longer rated life and improved light quality.

February is a time for us to pause and reflect upon the relationships that we hold dear. Being a member of an electric cooperative means that your relationship with us goes well beyond providing you with the energy you need to power your lives every day. The cooperative business model is the best one on earth. Our core business purpose is to serve as your electricity provider, but the larger mission of the co-op is to help make our corner of the world a better place. Our poles have roots and those roots run deep. We take pride in serving our member-owners because we are your neighbors, and we care very much about providing the highest level of friendly, reliable, and dependable service you expect and deserve. Here are six reasons to love being a member of your electric cooperative. Our mission. Electric co-ops were established to provide at-cost electric service. Providing safe, reliable, and affordable power has remained our mission since day one. You are a member, not a customer. Cooperatives are unique businesses because they are owned by you, the member. This means you have a voice in the way we run the co-op. Members elect the co-op’s board of directors and can run for a seat on the board if they wish to do so. Your vote and participation help shape the direction of the cooperative. We are not-for-profit. Unlike investor-owned utilities, which are operated to make the most profits for stakeholders, electric co-ops do not earn profits. Instead, any margins or revenue remaining (after all expenses have been paid) are returned to members in the form of capital credits. Capital credit returns are based on each member’s years of participation in the co-op. We are local, community-focused businesses. Because we are owned by the members we serve, electric cooperatives have a strong commitment to our local communities. In addition to providing safe, reliable, and affordable power, electric co-ops are involved in local community development programs and projects, such as Habitat for Humanity, Relay for Life, Youth Tour (and other youth engagement programs), etc. We are guided by a set of principles. All co-ops operate according to the same set of Seven Cooperative Principles: voluntary and open membership; democratic member control; members’ economic participation; autonomy and independence; education, training and information; cooperation among cooperatives; and concern for community. These principles guide every decision made by the co-op. We are committed to innovation. Because we answer to local members rather than far-away shareholders, electric cooperatives are more nimble and able to respond quickly to changing member needs. We are committed to experimenting and innovating in ways that benefit the local communities and members we serve. From all of us to all of our members, have a happy Valentine’s Day!
