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.

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. Specific warranty policies vary by manufacturer but typically cover replacement parts as indicated above up to one year after purchase. Please contact Greenhouse Megastore customer service if you have any questions about the warranty for your specific heater.

fast delivery , easy to install , fired right up
This heater came with my greenhouse and so far it is doing a great job. It's early Feb 2012 in the NW and I'm busy getting seeds started in the greenhouse. The Modine Hot Dog heats the place up in minutes and the optional thermostat is working like a charm. Just ordered another one for my new shop :)
Ordered on Monday and the unit was delivered on Wed. It was very easy to install. Used a drywall lift to raise it to the ceiling and bolt it in place. Hooked up the gas and electrical and it fired right up. The unit heats great! Very high quality product compaired to the big box stores. Love it!

Thank you for a prompt and careful delivery. heater is operating according to specs.

hot dawg hd75 heater
FAST shipping, Great product!! NO damage in shipping, and fired up first try.
Yes...Best Purchase Ever!!!
I was amazed how trouble free this unit was to install! The unit fired quickly and cycled as advertised. The unit has performed flawlessly. It is very quiet compared to the unit I replaced it with. Thanks, Greenhouse Megastore!
I just finished installing my new Unit Heater and I am very pleased with the operation and will welcome the heat in my garage.
Just finished installing the heater yesterday.. Fired it up, took a few minutes to purge but once it kicked in, I finally was able to feel my frozen feet again!! All the liquids in my garage were frozen before and now I can finally use them!
I am using this product in my work garage where I have to build cabinets and do painting and refinishing. I have to keep my garage at a certain temperature in order to work and for my cabinets to dry. This heater does a great job in keeping my garage at the required temperature.
Hot Dawg Is great
We moved into our house about 6 months ago and there was a HD-75 heater already in the garage but it was not working correctly. Upon further checking it was the Nat. Gas version probably 5 yrs. old. The problem is that it was hooked to Propane and I don't think it was converted. The problems were: Not heating very hot and sometimes it would light and sometimes it wouldn't. Anyways, After installing the HD-75 Propane today I was amazed at how much hotter the air was, it went from 45 to 55 in about 5 mins. Also The Greenhouse Megastore had the best price around and the Shipping was extremely fast. I will be back for my heating and gardening needs, Thanks IGC!
Its been a real cold winter in Wyoming this winter and the hot dawg heater has kept my shop nice and warm
Super Dawg is more like it.
I'm presently finishing my three car garage in a man cave fashion with all the goodys. The Modine H D75Unit Heater started this project off just right. Janurary in Ohio is pretty cold so I needed a good supply of heat to stay warm while working in the garage and the H D 75 did the job.
After researching for about a year, My mind was made up to purchase the Hot Dawg HD75. IGC by far offered this unit at the best price. I was surprised and pleased when it arrived in only two days. It took some effort to run the new gas line and install the vent but all in all the unit was easy to hang and has worked perfectly since the first time I turned up the thermostat. Thanks so much for selling a quality product at a reasonable price. PS. I am heating a very well insulated 1728 square foot garage / shop with this unit Thanks Again, Bill
modine hot dawg 75K
great heater, easy to install. the only bad thing i could say is the way they ship the louvers. being spring loaded is the only way the stay on. during shipping, three of them were off. after seeing how they work, they were quickly and easily replaced. no big deal. it is so nice to walk into a shop where is is warm.
