Building and Home Electrification

Be Future Ready with Building Electrification! 

What is beneficial electrification? Ductless Mini Split

Beneficial electrification is the conversion of heating systems, equipment, or appliances to run on electricity, instead of using a fuel such as natural gas, propane, or gasoline.

Electrification is typically discussed alongside energy efficiency activities such as insulation and air sealing. Energy and cost savings from electrification depends on how well insulated and sealed the building is, and vice versa. It is important to also consider improving energy efficiency when considering electrification options.

What can be electrified?

  • Cooking equipment
  • Furnaces and heating and cooling systems
  • Water heaters and systems
  • Clothes Dryers
  • Pool Heaters

Why Electrify?

Upgrading to electric appliances and HVAC can result in the following benefits for your home, office, and building:

  • Improved health and indoor air quality
  • Reduced energy costs
  • Excellent comfort and low noise
  • Minimal carbon footprint

Learn about the benefits of a electric and healthy new home 

What Can Be Electrified: 

Check out Southwest Energy Efficiency Project's (SWEEP) webinar to learn the key points to consider in electrifying both new and existing homes — for homeowners, new homebuyers, and HVAC contractors, as well as utilities, local governments, and new homebuilders. Also highlighted are the federal and state tax credits and utility rebates, which will more than cover the cost of replacing/upgrading your central AC to a heat pump system to deliver heating and cooling to your home. The webinar shows examples of homes making this type of upgrade, and of all-electric new homes with very low energy costs and excellent indoor air quality.

Swap your gas stove/range for an electric stove/range:

Electric Stove Cooktops:

  • How it works: Electric cooktops, which provide conductive, centered heat for pots and pans are the most widely used gas alternative. An electrical current flows beneath the glass or ceramic top’s surface, through a metal coil that glows hot and then transfers heat through the smooth top surface utilizing infrared energy.  
  • Benefits: Electric stoves are low cost and reliable while providing even heating and easy repairs.

Induction Electric Stove Cooktops: 

  • How it works: Induction cooktops use an electromagnetic field to generate heat directly in the cookware, meaning that the cooktop surface itself is cooler than a conventional stovetop. Induction cuts out the intermediate step of heating a burner to transfer the heat to the pan. 
  • Benefits: Induction stoves offer precise temperature control, quicker heating time, even heating, improved safety, and energy efficiency, In addition, because the surface does not heat up (only the pans and food), it is very easy and safe to clean up any spills.
  • Cookware Requirements: For cookware to perform on induction cooktops, it must contain iron (cast iron or some types of stainless steel) or have a layer of material with magnetic properties. To tell if a pot or pan is compatible with your induction stove, hold a magnet to the bottom. If the magnet clings to the underside, the cookware will work on an induction cooktop. If the magnet grabs the pan softly, you may not have good success with it. For more information, visit: https://loveelectric.org/cooking/

Swap your furnace for Heat Pumps: 

More efficient than furnaces or boilers, heat pumps serve double duty with heating and cooling, making this investment usable year-round. Combine this upgrade with other high impact energy-efficiency improvements to achieve significant energy and cost savings while transitioning from fossil fuels for a cleaner, healthier, and more comfortable home.

Learn about the benefits of heat pumps and what upgrade is best for your home and how to find financial incentives.

See below for more details on heat pumps

Air Source Heat Pump (ASHP):

  • Air-source heat pumps (ASHPs) are essentiallyreversible air conditioners. To cool your building, they transfer heat from theair inside to the outside. To warm your building, they transfer and“concentrate” heat from outside air to heat inside.
  • Benefits: ASHPs deliver more than four timesmore heat than the electricity it consumes and thus is highly efficient. It functionsas heating and cooling ( ENERGYSTAR ®)and eliminates the risk of carbon monoxide poisoning, gas leaks, and gasexplosions. These systems can work with existing duct systems or be ductless(see mini-split heat pump information below).

Cold Climate ASHP:  Recommended for Westminster's climate 

  • Cold-climate heat pumps achieve better energyperformance at colder temperatures than standard heat pumps and are designedfor higher efficiency over the entire range of winter temperatures. The commonlyavailable cold-climate heat pumps provide 70-80% of the heat pump’s maximumheating capacity at temperatures as low as 5˚F. High end models can continue tooperate at higher efficiencies than electric resistance or gas heaters even attemperatures as low as -10 degrees Fahrenheit ( NEEA).
  • Benefits: These systems reduce household energyconsumption by up to 40% (high efficiency) and can minimize or eliminate theneed for backup heating since it functions as heating and cooling. It also eliminatesthe risk of carbon monoxide poisoning, gas leaks, and gas explosions.

Mini-split heat pump (MSHP): 

  • MSHPS are typically a type of air source heatpump (see above).
  • Benefits: MSHPs save energy by only heatingareas that are in use while being high efficiency and functioning as heatingand cooling. These systems are also easy to install and eliminate the risk ofcarbon monoxide poisoning, gas leaks, and gas explosions.

Cold-climate MSHP: 

  • Cold-climateMSHPs include all the benefits of a MSHP, with functionality in temperatures aslow as -13 degrees Fahrenheit

Duct-less Heat Pumps: 

  • Ductless heat pumps, also known as “mini-splits,” move refrigerant, rather than heated or cooled air, from the outdoor unit to one or more  indoor units. The indoor units are typically wall-mounted and include a small fan. (See ductless heat pump diagram to right.) Ductless mini-split heat pumps tend to be more energy-efficient than ducted systems, in part due to eliminating ducts and requiring smaller fans (Source: https://loveelectric.org/heating-cooling/). 

Ground Source (Geothermal) Heat Pump: 

  • Ground source heat pumps work the same as an airsource heat pump except it sources heat from the ground instead of from outsideair. Ground heat is conveyed to the heat pump via long buried pipes or tubes ofeither circulated water or air. Geothermal works well in cold climates since deepersoils maintain higher temperatures compared to outside air during winter months.
  • There is more availability of higher efficiencymodels compared to air source heat pumps ( NEEA),saving additional energy and associated costs. The EPA claims energy savings upto 44% compared to air source heat pumps and 72% compared to electricresistance with standard AC units ( energy.gov).
  • Benefits: High efficiency models are morecommonly available and these unites have excellent functionality in coldweather. These units function as heating and cooling while eliminating the riskof carbon monoxide poisoning, gas leaks, and gas explosions.

Absorption Heat Pumps: 

  • Instead of using electricity, absorption heat pumps use heat, such as from solar or geothermal heated water to drive heating or cooling. This type of system is not as common as air source or geothermal heat pumps. Note that absorption heat pumps can source heat from natural gas-heated water, which is not considered electrified equipment
  • Benefit: These systems work especially well for niche situations where excess heated water is available. They’re high efficiency and function as heating and cooling while eliminating the risk of carbon monoxide poisoning, gas leaks, and gas explosions.

Combination Space/Water Heating Systems: 

  • Combine space heating and water heating systemstogether through various system types. Typically, either an integrated system,or an indirect system where water is heated for domestic use and air is blownover the heated water to produce hot air for space heating.
  • Benefits: Has a mix of the benefits of otherheat pump system types listed above depending on the configuration

Swap your boiler/water heater for: 

Electric Heat Pump Water Heater:

Benefits: These systems easily pay for themselves in annual energy cost savings and offer excess space cooling and high efficiency while eliminating the risk of carbon monoxide poisoning, gas leaks, and gas explosions. 

How they work: Electric heat pump water heaters pull heat fromthe surrounding air and use it to heat water. These units expel cold air, whichis desired during summer months. During winter, this cold air is still warmerthan the outside air and should not be ducted out (Learn more at  LoveElectric). Heat pumpwater heaters require installation in locations that remain in the 40º–90ºFrange year-round and provide at least 1,000 cubic feet of air space around thewater heater ( Energy.gov). 

Comparisons: 

  • A heat pump water heater will reduce your energy costs for hot water by 65% compared to a conventional electric water heater, and by 75% compared to a propane water heater. 
  • Your energy costs for hot water will be about the same with a heat pump water heater compared to an efficient natural gas water heater. 

Tankless (Point-of-Use) Water Heater:

  • Tankless (point-of-use) water heaters utilizeElectric Resistance heating rather than a heat pump and are therefore less efficient. These units work best only if space constraints don’t allow for aheat pump water heater with a tank, or if total hot water need is extremelyminimal.
  • Benefits: These units take up almost no space,never run out of hot water, and eliminate risk of carbon monoxide poisoning,gas leaks, and gas explosions.

Swap your natural gas clothes dryer for: 

Electric Resistance-based Clothes Dryer:

  • These units heat clothes via electric resistanceheating, passing an electrical current through a resistive material (typicallymetal) that heats up to dry the clothes. This is the most common clothes dryertype.
  • Benefits: Electric resistance-based dryers havea cheaper upfront cost, are easier to install and maintain, and offer a greatervariety of models compared to gas ( U.S.News ). They also have ventless options if an outside connection is unavailable.These units eliminate the risk of carbon monoxide poisoning, gas leaks, and gasexplosions .

Electric Heat Pump Clothes Dryer:

  • Electric heat pump dryers heat clothes via anair source heat pump. This type of unit is uncommon in the U.S. but is growingin popularity.
  • Benefits: Benefits include being more energyefficient than electric-resistance or gas units and also eliminate the risk ofcarbon monoxide poisoning, gas leaks, and gas explosions.

Rebates and Financial Incentives! 

New rebates and tax incentives make now excellent time for homeowners to consider adding a new heat pump or electric appliance. Heat pumps are very similar to central air conditioning (AC) systems, but they have a reversible valve that allows them to provide both heating and cooling. Because Colorado’s electricity is becoming more and more renewable-based, heat pumps significantly reduce the home’s carbon emissions from heating.

Available tax credits and rebates on a new heat pump installation should be more than enough to offset the incremental cost of a heat pump versus an AC or furnace system.

Federal Government

  • Tax Credits are up to 30% of the costs (up to $2,000) for heat pumps and similar equipment! See eligible equipment here!
  • Additional rebates are expected to be announced in the end of 2023, early 2024. 
  • Find out here which programs are available to you so that you can benefit from American made clean energy as soon as today, and sign up below to be the first to receive updates and take advantage of these opportunities.

Xcel Energy

 Xcel Energy is offering from $800-2,000 on rebates depending on the type of heat pump installed. Learn more here!

State of Colorado

  • The new Colorado State tax credit and sales tax exemption for heat pumps and heat pump water heaters is in effect! The tax credit (10%) and sales tax exemption (2.9%) add up to an additional 12.9% discount on the price of the equipment, not including installation charges. For example, if the price of a new ducted heat pump is $8,000 (not including installation), then the tax credit and sales tax savings would amount to $1,032. (Note that the tax credit applies as long as the homeowner pays enough state taxes.)

Demystyfying Beneficial Electrification: 

How do heat pumps work?

  • Air-source heat pumps (ASHPs) are reversible air conditioners.  Just like an air conditioner, in the summer they transfer heat from inside your home to the outside. In the winter they “concentrate” and transfer heat from the  outside to inside your home. 
  • Heat pumps provide both heating and cooling for your home, all in one unit. Heat pumps consist of an outdoor unit connected to one or more indoor units by refrigerant lines. ASHPs can use ducts to transport the warm or cool air throughout your home, like most home heating and central air conditioning systems.
  • There are also “ductless mini-split” and “mini-duct” systems (the latter being a hybrid of ductless and ducted systems). Air-Source heat pumps can also be used to supply heat to in-floor radiant heating systems "air-to-water heat pumps" (source: https://loveelectric.org/heating-cooling/). 
  • Check out this video from "This Old House" to learn more 

Do heat pumps work in cold weather?

  • Cold climate air source heat pumps and geothermal heat pumps are able to function at cold temperatures that residents typically experience even in the coldest winter months. It is important to purchase a heat pump capable of meeting heating requirements at the expected cold winter temperatures.
  • Electric resistance heaters can be installed as backup heating to help heat pumps meet heating load even at temperatures below what they are rated for. Alternatively, if a building has an existing natural gas heating system, that can be maintained to be used as a backup option.
  • Cold climate air source heat pumps can meet heating loads even at temperatures of -10 degrees or colder (NEEA).
  • If in an area where high volume of snow is expected, the exterior units may need to be raised slightly above the ground to keep clear of the snow.

Do heat pumps work well in Westminster’s climate, even without a backup furnace?

  • For a new home in all areas of Colorado except for the mountain areas, a cold-climate heat pump system can work very well without a backup furnace depending on how efficient the home was designed and built. However, for an existing home in these areas with a gas furnace, it will probably be more cost-effective to keep the existing furnace as a backup. You can learn more here.

How do electric and induction stoves compare to gas stoves?

  • Induction stoves have superior temperature control, quicker heating time, and even heating, allowing for easier, better cooking experiences compared to either electric resistance or gas stoves. They also do not heat up the stovetop itself, but rather the pot or pan, and therefore minimize the risk of burns. Indoor air quality is improved from not having indoor combustion of fossil fuels, which produce harmful pollutants. Induction stoves are energy efficient and are easy clean up due to their completely flat cooking surface.
  • Electric resistance stoves are cheaper than gas or induction stoves, are easy to repair, and more energy efficient than gas stoves

How do electric heat pumps compare by cost to standard furnace/ACs?

  • Electric heat pumps generally offer the cheapest way to cleanly heat and cool single-family homes in all but the coldest parts of the United States in coming decades, according to research released by the American Council for an Energy-Efficient Economy (ACEEE).

Hear from Shawn LeMons from Mitsubishi about the latest in heat pump technology, and how this technology can meet the demands of even the coldest of Colorado winters. In this webinar, Shawn busts common myths about heat pumps and answers questions in this engaging session. Note: This webinar was put on by the City and County of Denver, the requirements Denver has in-place DO NOT apply to Westminster. 

Sue electrified, you can too! Sue and her wife have spent decades electrifying elements of their home – from the heat pump to the induction stove – supplementing with solar energy along the way. Rising temperatures due to climate change were a major motivator for Sue as she worked to electrify her home. And while there is initial expense associated with electrification, the short and long-term benefits like lower heating and cooling costs and increased energy efficiency earn Sue’s “1,000% endorsement.”
