If you are looking to find a portable space furnace for sale fast the best venue to look is online.
There are multiple websites out there that sell all kinds of portable heating and a/c unit and temperature controls from warehouse stock.
And most of the time you can get them a lot cheaper than they are in the stores. I picked up a brand up-to-date portable space furnace from this a single wholesale website for only 40 bucks! I am not kidding you. 40 bucks for a brand up-to-date and untouched, unused portable space heater. This is a deal you would never find in a store no matter what, even if they had portable space oil furnaces on sale in a store the most you would get them for is maybe 71 bucks. That is a 30 dollar difference! The internet has its ups and its downs, however a single thing is for sure, and that is you can get good deals on portable space heaters, portable a/cs and also all kinds of temperature controls. With temperature controls, you can get older model dial temperature controls for as cheap as 16 bucks! And for digital temperature controls you can get them for about 25 bucks. Smart temperature controls are about the same though as in the store because they are still fairly up-to-date Heating and A/C technology. But at the same time it is still worth it because it saves you the hassle of going to the store, dealing with people and money on gas for the car.
