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.

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.

I love this heater
I bought this unit 3 years ago and installed it in my 24 X 30 two car, two story garage. I have a stair case in the back leading up to the second floor. I live in Southwestern PA and this unit runs from Nov. to April. I have the thermostat set at 65 all the time and it heats both floors without any problem. I wanted to wait before I posted my review and this unit is the absolute best thing I ever bought on line. I highly recommend this to any one debating on if they should buy one. Excellent product Hot Dawg, I recommend this unit to everyone I know looking for a great heater.
Super easy to install. Works great at 8000ft elevation.
So far so good
Unit has been installed for a month. Heats a 2.5 car garage with a loft no problem. Every thing works as it should. Nice strong fan and fairly quite as well.
