One Maryland shopper found that they could get a high-efficiency heat pump water heater for "free" thanks to a utility rebate.
But when they shared their findings on Reddit's r/HeatPumps forum, it drew a warning that the units would not actually be fully covered.
Here's what to know
In the Reddit thread, the original poster wrote, "You can get a free heat pump water heater with Pepco energy rebate," before adding an image of an $1,800, 50-gallon, super high-efficiency Rinnai unit in their cart for an estimated total of $0.00.
The OP did note that they "still had to pay sales tax on the original purchase price" and added that the instant rebate was only available through Halloween.

Commenters reacted largely negatively to the thread. One wrote, "Yay and now pay $5,000 for install." The OP responded, "Install is free when you do it yourself."
Multiple others shared their jealousy over the rebate, including one user who added, "Got excited then realized that says Pepco, not Peco." A third commenter similarly added, "I don't know what Pepco is, but that must be nice."
The top comment read, "You should know: not everybody in this sub lives in Maryland."
What can be done?
While Pepco's rebate window has closed for heat pump water heaters, utilities and even local governments often offer residents incentives to upgrade to higher-efficiency units.
Shoppers interested in any offer should confirm their eligibility, qualifying equipment, deadlines, and sales tax requirements with participating retailers. Additionally, as one commenter noted, getting a separate installation quote is a wise move.
