    This Pellet Stove is Eligible for the 30% Tax Credit Program

    ✅EPA Certified

    ✅75.5% HHV Efficiency

    • Beginning in 2023 through December 31, 2032, consumers buying highly efficient wood or pellet stoves or larger residential biomass heating systems may be eligible to claim a 30% tax credit that is capped at $2,000 annually and is based on the full cost (purchase and installation) of the unit.
    • This new 30 percent tax credit is available for appliances installed between January 1, 2023, and December 31, 2032.
    • Customers will claim their tax credit when they file their taxes on IRS form 5695 under “Residential Energy Efficient Property Credit “. They will need their purchase receipt (showing the cost of product and installation).
    • Customers will also need the manufacturer certificate stating that the stove qualifies for the credit and is at least 75 percent efficient HHV.
    • The credit applies to qualifying wood and pellet stoves and, unfortunately, not to gas stoves.
    • People who have zero tax liability may not qualify for the tax credit. It's recommended to consult a qualified tax professional to determine if the customer is eligible to take advantage of this tax credit.

    What our customers are saying...

    • Researched and ordered my fireplace from US FIreplace Store. Pricing was a fair value however, the customer service was EXCELLENT! I had an issue with the direct vent venting. I called US Fireplace and the correct items were sent out the next day AND Janessa stayed on top of my return authorization and sent me the permissions and documents I needed to return the incorrect item and no cost to me, including return shipping. Overall, I am a very satisfied customer and my fireplace looks and operates flawlessly. I am glad that I selected US FIreplace to source my direct vent fireplace. Thank you for the great service.

    • I had placed an order, through Lowe's Home Improvement, for an Electric Firebox: Revillusion RBF42. Ordered 1st part of January. Was told I would have it in 3 weeks. When checking to see is it came in, was told it was delayed to 3/15. Was then told is was delayed until 4/25. Waited until 4/27 to check on it. Was then told it was now delayed until August. This firebox was going in a new Sun Room addition. I could not get my final inspection until the Firebox was installed. I went on line and googled for this same product. US Fireplace Store web site was given to me. This was on a Saturday. I call and reached a very nice man. Explain what I was look for. He checked and told me they had 30 of them in stock. I almost fell out of my chair. I clarified with him the product I was wanting. I ask how soon could I get it. He told me it would ship today. Again, was amazed. It arrived on the following Monday. What a pleasure and a relief working with US Fireplace Store and their employees. Exceed my expectations.

    • Great prices, quick delivery and fast hassle free services on the issue I encountered. I had purchased an electric fireplace unit that would not fit into the existing fireplace space. With one email I was able to get the wrong fireplace refunded and picked up at my home at no extra cost and the new one I purchased and delivered free of charge. Great company.
