When you need to heat a workshop, garage, or warehouse bay, a hydronic unit heater is a straightforward way to push warm air into open space. The hard part is matching the unit's orientation and airflow to the room, and the price spread among Dayton options makes it tempting to just grab the cheapest listing. Here the four choices range from a $250 horizontal heater with a cosmetic flaw to a $1,426.99 horizontal model with 1,400 cfm, plus a vertical 595 cfm unit and a second horizontal 5Pv27 listing. Let's sort them by airflow, mounting style, and price.
Quick take
- Need the lowest listed price and can accept a dent? The $250 Dayton 5Pv27 listing is the most direct entry.
- Want a clean, never-used 5Pv27 with high airflow? The $769 open-box Dayton 5Pv27 listing is the middle option.
- Need vertical air delivery for a tighter footprint? The $972.99 Dayton 5Pv63 vertical unit is the only vertical in the group.
- Want a horizontal unit with 1,400 cfm and the most compact depth? The $1,426.99 Dayton 5Pv52 is the most expensive horizontal choice.

Product notes
Dayton 5Pv63 Hydronic Unit Heater, Vrtcl, 595Cfm
Dayton 5Pv63 Hydronic Unit Heater, Vrtcl, 595Cfm is the only vertical model in this group. It is priced at USD 972.99 and listed as a suspended vertical hydronic wall and ceiling unit heater. The 595 cfm rating is the lowest of the four, so think of it as a solution for a smaller zone or a spot-heating need rather than a large open bay. Its listed depth is 19.7 inches and length is 19.6 inches, giving it a blockier footprint than the 5Pv52's 13.9-inch depth. Choose it when you need vertical air direction and a wall or ceiling mount, and you don't need the higher airflow of the horizontal 5Pv27 or 5Pv52. The limitation is the lower cfm, which will not move as much warm air into a large space.
Dayton - 5Pv27 Hydronic Unit Heater 27-3/4" H (lower-priced listing)
At USD 250.00, the lower-priced Dayton 5Pv27 listing is the lowest-priced option in the comparison. The listed specs include a 15-inch depth and the same suspended horizontal hydronic wall and ceiling unit type as the other 5Pv27 listing. The description says the unit is new, but it also notes a dent in the fins, so the physical condition is not perfect even though the functionality is described as unaffected. This makes it a reasonable choice if you are comfortable with a blemish and want the 5Pv27 horizontal design at the lowest possible listed price. The limitation is that you are buying a dented unit without a box; if you need a pristine heater, the other 5Pv27 listing is the cleaner path.
Dayton 5Pv52 Hydronic Unit Heater, 24" H, 1400 Cfm
Dayton 5Pv52 Hydronic Unit Heater, 24" H, 1400 Cfm is priced at USD 1,426.99, which is the top of this price range. It is a suspended horizontal hydronic wall and ceiling unit heater with a 1,400 cfm rating in the title. Its listed depth is 13.9 inches and length is 23.1 inches, making it the shallowest horizontal option here but also a longer unit. If your heat load lands between the 595 cfm vertical and the 2,200 cfm 5Pv27 horizontal, this 1,400 cfm model sits in that middle band. It costs more than both 5Pv27 listings, so the decision comes down to whether the 1,400 cfm output justifies the higher price for your space. The limitation is the price, which is the highest in the group.
Dayton - 5Pv27 Hydronic Unit Heater 27-3/4" H
The second Dayton 5Pv27 listing is priced at USD 769.00 and comes with a description that spells out the 5Pv27's horizontal specs: 2,200 cfm, 27-3/4-inch height, 23-3/8-inch width, 18-inch fan, 4.5 amps, and 1-1/2-inch connections. It is described as an open-box item that has never been used or tested, and it is listed as New. If you want the high airflow of the 5Pv27 without the dent mentioned in the lower-priced listing, this gives you that cleaner specification. The trade-off is the price: it is roughly three times the $250 listing for the same model family, and the open-box status means the item is not sealed in its original packaging. Use it when you want the 5Pv27's horizontal output and are fine with an open-box condition.
