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
Based on our experience in selling Modine Hot Dawg Heaters, we have written up a troubleshooting guide that deals with the issues we most commonly hear from customers. - Troubleshoot a Modine Hot Dawg
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.

Modine 100,000 but power vented
Installation was easy and it worked well right out of the box. No adjustments needed for flame or pressure.
Modine Natural Gas Heater
Easy to install,works great. Very well built.
unit worked great right out of the box comfortably heating a 50: by 22; by 26 boat shed in a cold Maine winter
This unit was purchased as a replacement for an over-sized oil furnace for our 900 sf hoophouse. The heater is absolutely THE BEST! Very quiet, highly efficient, excellent heat distribution without blasting a firewall of heat across the house. The only negative thing I can say is that the installation kit that comes with the heater is basically useless, and you WILL end up having to purchase a significant amount of parts to install it properly. That being said, I'm very, VERY pleased with the heater and highly recommend it!!!
Warm and Toasty
My heater and thermometer shipped out very quickly. There was a bit of a mix-up with the venting kit which had been back ordered. When I phoned, the problem was very quickly rectified. I am very happy with the polite, professional and effective response that I received. In the day and age of bad service, it was refreshing to speak to someone that obviously took pride in the job that they were doing. I am impressed with the amount of heat that this unit kicks out. Living on the Canadian prairies, my plants will love basking in its warmth this winter!
