Understanding the Federal Tax Credit
The federal tax credit for energy-efficient home improvements is designed to incentivize homeowners to invest in products that significantly reduce energy consumption. Here’s what you need to know:
- Non-Refundable Tax Credit: This credit lowers your tax burden, but it won’t create a refund if the credit amount is higher than what you owe.
- Cost Calculation: The amount is based on a percentage of the total cost of the project, which includes both the equipment and installation. This can apply to upgrades like gas-fired tankless systems, heat pumps, hot water boilers, oil furnaces, oil water heaters, heat pump water heaters, natural gas heat pump units, and other qualified energy property.
- Cap on Credits: Homeowners can claim up to $3,200 in tax credits per year, with a cap of $2,000 for heat pumps, boilers, and water heaters, and an additional $1,200 limit for other home envelope improvements such as air sealing materials, insulation materials, electrical upgrades, and energy-efficient exterior doors.
- Legislative Backing: These benefits fall under the Inflation Reduction Act of 2022 (often called the Reduction Act of 2022), extending federal support for upgrades through 2032. This includes improvements in an existing home, a manufactured home, or a qualifying mobile home, as long as it is your principal residence. A cooperative apartment also qualifies when you are the same customer living in the unit.
By using this credit, homeowners can save money, increase efficiency, and boost home value. When paired with utility rebates, air sealing, home energy audits, or programs that support gas, propane, or oil systems, the total savings can become even more meaningful.
Eligible Products and ENERGY STAR Certification
To qualify, the products must meet defined criteria:
- ENERGY STAR-Certified Products: Only ENERGY STAR-certified items, such as tankless water heaters, heat pumps, heat pump water heaters, central air conditioners, biomass stoves, biomass boilers, and certain natural gas, propane, or oil systems, qualify. These products are rigorously tested and meet stringent efficiency criteria set by the U.S. Environmental Protection Agency. For homeowners comparing different tankless water heaters, reviewing features like UEF ratings and fuel type options can help confirm whether a unit qualifies under federal criteria.
- Uniform Energy Factor (UEF) Requirements: For tankless units, ENERGY STAR requires a UEF greater than 0.95. For gas storage water heaters, the requirements are:
- Tanks under 55 gallons: UEF above 0.81
- Tanks 55 gallons or more: UEF above 0.86
- Other Eligible Products: Items such as natural gas, electric or natural gas, natural gas propane, or gas propane or oil systems may qualify when they meet the federal guidelines for residential energy property.
The credit applies only to an existing home in the United States that you occupy as your principal residence during the calendar year of installation. Rentals, vacation homes, and non-owner-occupied units do not qualify.
Using the ENERGY STAR Product Finder
Homeowners can easily find eligible products using the free online ENERGY STAR Product Finder. This tool allows you to:
- Search by category, brand, or model, which is useful for comparing heat pumps, heat pump water heaters, central air conditioners, gas-fired tankless units, and hot water boilers.
- Check UEF values, energy factor details, and efficiency ratings.
- View manufacturer information to confirm eligibility with the company directly.
Using this resource helps ensure every upgrade—whether it’s part of the annual total limit or tied to advanced tier options—meets federal standards and stays within the program’s total limit for the year.
How to Claim and Maximize Your Tax Credit
Claiming your tax credit for a new tankless unit is simple when you follow a clear plan:
- Purchase an Eligible Product: Start by selecting an ENERGY STAR-certified tankless water heater that meets the UEF requirement. To keep your eligible system running efficiently throughout the taxable year, regular tankless water heater maintenance ensures the unit performs at its rated efficiency and protects your long-term savings.
- Obtain Manufacturer’s Certification Statement: This document confirms the product qualifies for the home improvement credit. Keep it with your records, along with the model number, as proof during filing.
- File Form 5695: Include this form with your tax return to claim the credit. Ensure all information is accurate to avoid delays.
- Combine Multiple Upgrades: Consider consolidating several energy-efficient home improvements in a single year. This strategy can maximize your credit amount, especially since unused credits can be carried forward to future years.
- Consult a Tax Professional: A tax expert can check whether your setup qualifies—especially if you live in a manufactured home, mobile home, or cooperative apartment, or if you’re mixing systems like propane, propane or oil water units, or natural gas appliances.
Following these steps helps cut the upfront cost of installing a tankless unit and other energy-efficient home upgrades, giving you a smoother path toward better energy efficiency and lower utility bills.
Local Incentives in Rockwall, Texas
Along with the federal credit, Rockwall homeowners can tap into local rebates and programs that support energy efficiency standards and lower project costs:
- Oncor Electric Delivery Programs: Oncor offers rebates for energy-efficient home improvement projects, including insulation and HVAC work. Programs usually run from February through November. Homes must use Oncor as the electric delivery provider, and both owners and renters (with approval) can participate. This can pair well with upgrades involving electric systems, heat pumps, or gas heat pump water setups.
- Texas Gas Service Rebates: Homeowners investing in energy-efficient natural gas appliances can benefit from rebates offered by Texas Gas Service. By purchasing qualifying appliances or equipment, residents can receive cash back, promoting both energy conservation and cost savings.
- State Energy Conservation Office (SECO) Initiatives: SECO partners with Rockwall County and nearby communities to improve local energy use. They adopt updated codes for residential and commercial buildings—supporting everything from insulation upgrades to efficient hot water and heating equipment.
These programs help Rockwall homeowners bring down project costs while improving long-term performance and comfort. If you live within Intown Plumbing’s service area, you may also have access to localized rebates and programs that pair well with the federal credit.

Frequently Asked Questions about the Tankless Water Heater Tax Credit
Is there a federal tax credit for tankless water heaters?
Yes. Tankless units can qualify for the federal tax credit under the current residential energy property rules in the Inflation Reduction Act. To claim the credit, the tankless water heater must be ENERGY STAR certified and installed in your principal residence.
This applies whether your home is powered by electricity, natural gas, or other approved systems. Units that fall within the program’s highest efficiency tier give you the best chance of qualification, especially under the updated annual total limit and generous annual limits.
What is the $6000 tax credit?
The federal program itself caps at $3,200 per year, but some state incentives and utility programs—especially those involving heat pumps, heat pump water heaters, or advanced natural gas heat pump systems—can push total savings closer to $6,000 when combined with local rebates.
These outside programs operate separately from the federal credit, which has its own structure, including some lifetime limits depending on the type of improvement and the expanded version of eligible upgrades.
Do tankless water heaters offer any savings in energy consumption?
Yes. Tankless heaters warm water only when you need it, so they waste far less energy than older boilers, outdated electric systems, or aging oil furnaces or hot water setups. Homes switching from older propane or oil water heaters often see noticeable gains in energy efficiency, especially when paired with improvements like upgraded central air conditioners or heat pump water heaters elsewhere in the home.
Can you deduct water heater replacement on taxes?
You can only claim a replacement if the new water heater meets federal efficiency rules and qualifies for the credit. Standard replacements that don’t meet ENERGY STAR requirements are not eligible. If your upgrade includes related electrical work—like sub-panelboards or branch circuits tied to efficient electric systems—the project may qualify as part of broader eligible improvements, depending on how it fits within the program’s total limit for the year.
