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

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.

Spiral portion of blender did not hold up
Color: Black
It was wonderful for 10 weeks. We used it almost daily and sometimes twice a day. It frothed quickly. It proved a satisfying blender until approx 10 weeks of use. The wire spiral on the end started to slowly wind off. It worked OK but wobbled and frothed weakly at that point. For short term use, for very infrequent use, it will be fine. Looks acceptable, easy to use. Changed the batteries one time. For the price, I am not unhappy. Have now replaced it with a more expensive one on Amazon. Thank you Amazon for giving your shoppers the opportunity to leave our feedback. It is one of your most appreciated features.

Great little frother
Color: Black
This is a great little frother. It is powerful and really frothes up what ever you are trying to stir, sometimes too much for what I want it to do. Do not get water or liquid into the motor area or the item will stop working. Recommend this item.

Tiny, but mighty
Color: Black
I ordered this in July, 2023, and it works very well, great speed. I use it every single morning, to mix my mushroom coffee, cinnamon, and collagen protein. If you're looking for a really good frother, this probably isn't going to meet that demand. It does give some froth, but nothing crazy. I have read reviews that mention "no longer worked after replacing batteries", but mine is still great even after replacing them, which I didn't have to do until after 3 months of usage. I don't know if the color matters in relation to that, but I bought the red one. I would definitely recommend this product.
