Features
- Hush-Puppy Quiet Operation
- The HDS30 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 HDS30 has an incredibly low profile design, measuring in at a height of only 12.2 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 HDS30 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 HDS30 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.
- Separated Combustion Venting System
- The separated combustion venting system quickly and efficiently brings flue exhaust from the unit heater to the outdoors while providing the unit heater with outdoor air for combustion, keeping installation costs low while preserving indoor air quality.
- Baked Polyester Paint
- The HDS30 features a neutral colored baked on polyester paint, providing excellent corrosion resistance and durability while blending in with a wide variety of environments.
- Modine Installation
- Installation by a professional installer is required by the manufacturer.
- Finger Proof Fan Guard

Modine HDS30AS0121 Reviews & Ratings
The Hot Dawg unit heater is one of the top residential unit heaters available. Meant for garages and workshops, the HDS30AS0121 is a quiet heater built with a low profile so it can fit almost anywhere you need. This is also a great option if the space you'll be heating frequently has air-borne particles introduced by your work. The sealed combustion technology will keep all extraneous materials from your workshop a safe distance from your burner, keeping you safe and your heater operating efficiently. A permanently lubricated motor helps reduce maintenance costs and electrical knockouts keep your installation costs low, as well. You can't go wrong with this reliable unit heater from Modine.

Great unit for heating a shop

Review Posted 12/21/2018
I have had the 60K HDS unit installed in my wood shop for just over a week now. It is working great. The area I am heating is 25 x 24 with 12 ft ceiling. We have had temps under 20F and it maintains 50 easily, hardly ever running. It can also get it up to 60 quickly when I am working in the shop.

Excellent product and service
By Allan G

Review Posted 12/17/2018
We have a metal building with no insulation. In South Texas our winters are basically in the 40's and 50's with occasional 20's to 30's. Our heater warms it up quickly where we can work in short sleeves. If I would insulate, then I'm sure it wouldn't run very much. Can't speak to the fuel consumption as we are on propane and it was just filled. Will update later. This appears to be a 5-star product.

Only Way I Could Be Happier if it was a Bit Quieter
By Mark T.
Mount Blanchard, Ohio
Purchased 09/13/2013 |
Review Posted 10/02/2017
Have used this for two winters and have been quite pleased. The "separated combustion" design was the most important feature of the unit for me - the real reason I chose it. No risk of an explosion from dust or fumes in my woodworking shop. It was relatively easy to install - I did it myself - and it has been trouble free.

Great Product!
By Dennis M.
NORWICH, Connecticut
Purchased 09/06/2017 |
Review Posted 10/02/2017
Fit our needs perfectly! Needed a heater/furnace with a sealed combustion chamber and something that would mount close to the ceiling. Also was able to find the btu I was looking for. Had it installed by a licensed plumber, with no issues there. Not a bad looking unit, and when its running it is very quiet with plenty of warm air flow. Price was right and it shipped free very quickly! Only been installed for a day but it is running absolutely perfectly! Extremely happy!
