Modine HD45 Hot Dawg Review – Features

[su_divider top=”no” divider_color=”#ffcc00″ size=”2″]

modine-hot-dawgIt has 45,000 BTU’s of output, capable of heating a 1000 square foot area in a matter of minutes. It’s a definite pick for those serious about keeping their space warm for a long time. If you have a small space or just need a warm garage for a few hours a week you may want to look at some other options available.

As I mentioned, this heater is right on the line of residential and commercial, so while it may seem the same from the outside it is a powerhouse on the inside. It’s quiet when compared to other heaters and very efficient (80% burn efficiency). This efficiency is actually rather good, so expect to save a good amount of money with a natural gas heater over time (vs. a traditional electric heater).

Modine HD45 Installation

You’ll have to install it yourself (or get a professional to do it), but it’s able to be hooked up to a thermostat for temperature control. My favorite part about this heater is the fact it’s both a natural gas garage heater and an electric garage heater, you have options.

If you’re primarily going to be fueling it with gas you’ll need ventilation. While other heaters require you do modify the space for ventilation, this heater allows a vent pipe to be attached, making the ventilation process much easier.


This unit weighs in at a beefy 60 pounds, so make sure you put it in a spot that can support its weight, whether that be a wall mounted or on the ceiling. It comes with standard safety features also making this a serious contender for any space.

The best part about this heater is it doesn’t obnoxiously spurt out hot air, instead is a steady stream that evenly spreads throughout the room. If you’re working with varnish or paints you’ll understand why you don’t want heavy spurts of air throwing up dust or other debris. If you have a small garage, consider a typical home space heater, because this Hot Dawg is for serious heating and spaces used often.


Overall this is a powerful heater for any space needing a constant warmth in cold weather. No need to wait for the room to heat up as this heater can literally heat up 1000 square foot room in a matter of minutes. If you’re looking for top of the line efficiency and looking for the best quality garage heater on the market, you’ve found the one.
