Features
- Hush-Puppy Quiet Operation
- The HD75 is incredibly quiet during operation. This allows the heater to be inconspicuous yet effective at all times - it will not distract you from your work.
- Low Profile Design
- The HD75 has an incredibly low profile design, measuring in at a height of only 18 inches. It can be mounted with a one inch clearance from the ceiling on only two angle brackets, keeping the unit heater out of your way.
- Aluminized Steel Heat Exchanger
- The aluminized steel heat exchanger passes lower manufacturing costs along to the consumer, is incredibly durable and is protected by a full 10 year warranty by Modine.
- Electric Knockouts
- Electric wiring knockouts and field wiring connections on the HD75 keep installation costs low and save time during both installation and maintenance for your contractor by simplifing all required electrical work.
- Permanently Lubricated Motor
- The motor on the HD75 has a permanent, long lasting lubricant straight from the factory. This means that the motor never has to be oiled, reducing maintenance costs, general wear and tear, and operational noise.
- Power Venting System
- The power venting system quickly and efficiently brings flue exhaust from the unit heater to the outdoors, and requires minimal installation labor. This keeps installation related costs as low as possible.
- Baked Polyester Paint
- The HD75 features a neutral colored baked on polyester paint, providing excellent corrosion resistance and durability while blending in with a wide variety of environments.
- Mounting Brackets Included
- Models HD30-75 include two mounting brackets for convenience.
- Modine Installation
- Installation by a professional installer is required by the manufacturer.
- Finger Proof Fan Guard
- This model features a Finger Proof Fan Guard standard.
The Modine name has become synonymous with quality unit heaters in millions of homes and workshops all across the world. The HD75 is no exception to this rule, with sound engineering and reliability to last decades on end. Field wiring connections and electrical knockouts allow the HD75 to be installed nearly anywhere, while it's quiet operation and a natural, neutral coloring allow it to blend in seamlessly in any location.

Replaced a 20 year old Granger heater with this. It is the same size and much quieter. Probably more efficient also (need a season to tell).

So far, this unit heater is awesome.
It replaced an old direct vent wall mount mobile home style furnace that wasn't adequate for the size of my barn.

Excellent Heater, Great Output And Throws Heat A Long Way

Review Posted 01/31/2022
Bought this heater a while back but finished getting it installed before X-mas. Had electric heater on ceiling last year and it struggled to keep shop/garage warm (26 x 56) with 12 ft sidewalls. The Hot Dawg keeps it toasty warm with no trouble at all and in the first 6 weeks at about half the cost of the electric heater. A+ unit, would certainly recommend so far, only time will tell but for now all thumb up.

Finally My Shop Has Heat!
By Bill C

Purchased 01/20/2021 |
Review Posted 02/13/2021
After a few years living without heat in my garage workshop I bit the bullet and ordered the Hot Dawg 75k propane heater from eComfort. I ordered over the phone since I had a few questions and that process was perfect! My heater was delivered very promptly and the delivery service was excellent too. Installation of the heater was pretty easy, but I had my local propane supplier run the gas lines and do final hookup.
The unit fired right up and runs like a champ! I need to figure out the sweet spot for my preferred working temperature but even set low for the first run it is comfortable in the garage while it's 27° outside. This unit moves a lot of air
