Hot Dawg HD VS HDS

[Lewit12]

Getting ready to pull the trigger on a heater for my 32x48x12 pole barn here in West MI. Looking at the 75,000BTU Hot Dawg heater. Is the HDS really worth the extra 500$? I’m not in the shop a ton. Going to set the temp at 50 when I’m not there and crank it up when it’s time to work on something. Just looking for your opinions.

I have a shop here in the Midwest about the same size as yours. I installed the Hot Dawg HDS(100,000BTU) unit last year and love it! The stainless steel heat exchanger is well worth it IMO.

I set mine to 40 when not using it and 65 when I am. I'm using NG for fuel and 3 ceiling fans for circulation running 24/7.

My fuel cost per day last heating season was 80 cents. No complaints here.

Depends how you use your garage

The HDS model uses external fresh air for combustion instead of indoor space air used by HD model.


I bought a 75k Hot Dawg HD for $575 shipped and love it

Super cheap $65ish vent kit also

There maybe a stainless steel model

In the features not seeing stainless steel heat exchanger in the HD Vs HDS

Additional Features of the HDS Model:

Designed for environments where dirt, dust, humidity, fumes or other contaminants may be present
The separated combustion Hot Dawg® draws its combustion air from outside the work space, ensuring the unit always has plenty of fresh, clean air to breathe
The fresh-air supply reduces common concerns about dusty, dirty or humid applications, providing greater durability and reduced maintenance
Drawing combustion air from the outside increases overall heating efficiency
External gas connections
Greater CFMs than the standard Hot Dawg® model (QC #20855)
All HDS models ship ready-to-go

Have a look at Sterling Garage Guy heaters. They are all set up for separated combustion from the factory, if you choose to set it up that way. Hot Dawg HDS models are just separated combustion, not stainless unless explicitly ordered as such which is a separate cost. Sterling heaters are an extra $175 for stainless.

For what it's worth I got the 45k unit with the regular heat exchanger. I am using regular B vent for exhaust and pulling intake from inside. I don't know that I'll bother adding a fresh air intake or running the concentric vent, probably not necessary for my use.

As stated previously, the HDS has a separated combustion chamber whereas the HD does not and has "open flames". If your garage is used for woodworking, welding, or auto repair where there will be chemicals used often, I would recommend the HDS. For a normal garage where work will be performed sporadically your probably fine with the HD unit. I would just ensure you pick a good location for the heater so its not near any combustibles.

Now, where's pics of your garage?
