I bought this to heat my back porch converted into a greenhouse. We have had a very cold winter this year, but Big Buddy has no problem keeping my greenhouse nice and toasty. Fresh salads with tomatoes in January? Beats anything ‘store bought’! You know , those awful ‘crunchy’ winter tomatoes? Not mine, LOL.. PLUS, I start my own bedding plants for about 15 cents each. No more $5 each Bonnie plants for me! Mr. Buddy will save me $1000’s of dollars off my grocery bill!

TAME WINTERS RAGE WITH THIS BEST FRIEND

These heaters will run you out of the standard appartments on high so medium or low will keep your home warm for when sisaster strikes, combine this with a solar back up for power and you will have a safe, warm home for you and your children, keep cralwers away as the flame can be hypnotising to them, use the rear mounts to securly and safely mount to the wall. Fan is needed to prevent condensation.
