Quick Verdict
If you are shopping for a hydronic unit heater and can accept a slight cosmetic flaw, the Dayton 5Pv27 at USD 250.00 deserves a look. It's listed as new but without the original box, and it has a dent in the fins that the listing says does not affect use. For a garage, workshop, or other utility space, that trade-off may be worth the price.
Who It Suits
This unit fits shoppers with a hydronic heating system who need a 27-3/4-inch-high heater for a large open area. The product type is a suspended horizontal hydronic wall and ceiling unit, so it's meant for spaces where an overhead or wall-mounted heater makes sense. If your priority is functional heat rather than showroom looks, this is a realistic candidate.
What Stands Out
The most notable aspect is the combination of new condition and a visible dent. You're getting an unused unit, but it's not flawless. The description explicitly says the dent does not affect use, which is a helpful assurance. The price of USD 250.00 is concrete, and the 27-3/4-inch height gives you a clear sense of the heater's physical footprint.
Meaningful Trade-offs
The dent is the main thing to weigh. If the unit will be installed in a workshop or boiler room where no one will scrutinize it, the blemish likely won't matter. But if you need a heater that looks sharp in a customer-visible location, this is not the one for you. The missing original box is a secondary consideration, especially if you plan to store the unit before installation or keep it for resale.
