Many of our customers happily report that purchasing a Hot Dawg heater from the Greenhouse Megastore helped them save 50% or more off the unit price received from a local HVAC installer. However, for safety reasons and to minimize installation problems Modine strongly recommends having a licensed HVAC technician install your Hot Dawg heater. Although we are happy to offer limited technical support for your Hot Dawg purchase, we can NOT install the heater for you over the phone nor are we able to troubleshoot problems you may experience if you choose to install the heater yourself. By purchasing this heater from us, you accept sole responsibility for installation and agree to abide by Modine's limited Warranty

Modine offers a 10 year limited warranty on the heat exchanger and a 2 year limited warranty on all other components. Please note this warranty covers parts only and does not cover any labor costs associated with repairing the heater. View Warranty (PDF)
Heater Warranty and Return Policy
It is the customer's responsibility to carefully inspect heaters for damage before accepting delivery since heaters are usually not returnable once delivery is accepted. Obviously damaged heaters should be refused and Greenhouse Megastore customer service contacted to make arrangements for a replacement unit. Once delivery is accepted Greenhouse Megastore will gladly provide replacement parts under the manufacturer's warranty to repair damaged or defective heaters; however this warranty does not include any labor costs associated with installing these parts. Warranty issues should be diagnosed by a certified HVAC technician since parts deemed not to be defective by the manufacturer are not available for credit back to the customer.

Love this Little Guy
I installed this unit in my garage so I could have heat to work in there for the winter. It's a 30'x60' and this little guy has NO problem heating it to 70F. I kept on at 45F for the winter to keep the cars and tractor warm and melt snow, and it didn't even make a noticeable bump in the heating bill. It was easy to install and just works. I would recommend this many times over.
This was purchased to heat an attached 3 car garage (almost 800 sq/ft). It does a fantastic job; it's quiet and heats up to whatever temperature i've set so far. It's definitely a high quality heater. I looked at the local brands of heater available at menards and I was concerned that in the future parts availability may be a problem, but modine is an established brand and should be around a long time. Its cheap to upsize the unit but i reccomend sticking to manufacturer recomendations for sizing
Modine HD45 Unit Heater
This little heater is amazing. I wish I had found this years ago. We will install many more of these in the future. Easy installation, works great, nice looking, it has it all!!!
I bought this heater for my 10x20 foot greenhouse. My husband got in installed right before we had the coldest weather in over 30 years. It did a great job! I would recommend this heater to anyone needing to heat a greenhouse, shop or garage.
Great service and price
After fully researching my needs for a heated 2.5 car garage I selected the Modine Hot Dawg propane heater supplied by Greenhouse Megastore. I learned to spend the extra money on the Modine as opposed to Mr. Heat. The unit arrived promptly with no shipping defects. I did not order the extra complete set of venting components, believing I could purchase units from a home supply store for less. That was not case. I will now be placing an order with Green house for the quality vent pipes.
Great service and fast shipping. High altitude kit was shipped after the fact at no charge with fast shipping time. Thanks!!
Worth The Price!
Purchased for our restaurant, whisper quiet, great heat. Keeps our whole 30 X 40 building warm. Very easy to install, completed in about 2 hrs.
I purchased the 45,000 BTU HotDawg. The compact size ,ease of install and purpose for this unit will work perfectly for my residential application. I will use this heater , NG forced vent in my large attic to keep me warm during the cold winter days and evenings .When not in use I will turn the thermostat to 45 F. With in 5 minutes of the unit being on (very quiet) I'm back in business. Thank you Modine,Big Bear
Best Purchase EVER!!!
When I purchased my Modine Hot Dawg Natural Gas furnace a couple of years ago, I got it for my greenhouse. I actually got a low-profile one for garages, as that is what I needed for the ceiling height, yet still be above the water sprayers, and it has worked marvelously. In Oregon these heaters are priced at $1000 and up, yet even with shipping I was able to save 45% by purchasing it through MegaStore! My husband installed it and we've had no problems whatsoever...it's the BEST purchase for my greenhouse we've made yet! I LOVE IT!!!
Great Garage Heater
I ordered this product online and was impressed by the reviews about the product and the Mega Store satisfaction comments. When I received the billing information the invoice showed that the heater would need a high altitude conversion kit. The box was delivered well packed with a sticker that said additional parts included. The conversion kit was included, sized for the altitude of my garage (thanks Google) and the installation was a snap. In short I recommend the product, my garage shop is a large two car and the heater keeps it toasty even in very cold conditions; I also highly recommend the Mega Store.
Absolutely Best Purchase Ever
I purchased the Modine 45 heater and installed April 2007. It is the best quiet most efficient heater I have ever used. I also purchased the horizontal vent kit with heater. The entire installation including running the gas line was simple, took total 5 hours. Very pleased highly recommend to everyone I know.
Mounts out of the way above. I have a hd45 in my 24x16 garage. I have been running mine for 4 years. Recommended it to 2 friends who purchased 1 hd45 & 1 hd60 both are happy as well, 2 of us run propane the other Nat-Gas.
We received the product on time. One of the louvers was bent and a spring was missing, but they replaced the parts immediately by express service to arrive at the same time our installation people were due. Job well done by Customer Service!
Best Price Around
Great purchase, the only thing I would do different if I were to do it over is purchase the vent kit with the heater. Modine Quality and MegaStore Value! Product was well packaged and made it to Alaska without damage.
