Installation

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

Excellent Heater

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 :)

Great Heater

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!
