Most people do not bother to put any sort of heat in an connected garage.
This is because the motorcar and some storage things are there and these are not affected by varying temperatures.
Plus, if the garage is connected to the house it seldom drops to below freezing due to the transference of residual heat from the house itself. In our case my good friend and I had a big attic space above the garage and in order to use it my good friend and I needed some sort of temperature control. During the summer time months my good friend and I simply used fans and vents to eliminate the excess heat, however during the winter time my good friend and I needed a form of heat that was cost effective and didn’t require HVAC duct. The forced air system in the house was not big enough to connect to the additional space so my good friend and I wanted something totally separate. We consulted with our HVAC business and he advised that my good friend and I look into some sort of radiant heater. As it is an attic space he said that if my good friend and I installed electric baseboard heating it would be best. We would just have to position the items in there so that they were not blocking the registers, and he also said that if my good friend and I number one my good friend and I could use infrared radiant tube heaters that would be installed along the ceiling if my good friend and I didn’t want to worry about blocking the heat source, but we were happy to hear that my good friend and I had so several possibilities available and decided to go with the baseboard registers, now my good friend and I have the ability to store more things safely and not worry about the temperature in the attic no matter what season it is.
