Shaver Wood Burning Furnace Reviews

The Shaver Outdoor Wood Furnace...

provides hot water to work in conjunction with your existing forced air, boiler or radiant system as well as providing domestic hot water plus heating for spas, hot tubs and pools PLUS driveways and sidewalks! Our
systems tie in easily to virtually any system; floor heating, forced air, boilers, water radiators and more.

Even if you don't have an existing system, we can make it work for you!

An outdoor wood furnace is a wood burning  furnace that sits outdoors - keeping the mess, smoke and bugs outside. The furnace, looks much like a small utility building. It is a wood fired, water-jacketed stove.

The hot water is circulated through underground pipes to the inside of the house, where they are hooked to a heat exchanger in the majority of cases. It is also directly plumbed to the hot water heater, eliminating the need for a $200 side-arm heat exchanger for that purpose. It can also be tied in with an existing Hydronic floor heating system or boiler.

Heating with an outdoor wood furnace has never been easier. Instead of moving the wood and corresponding mess and bugs indoors, the wood burning furnace is outdoors - next to the wood. 

Load it once at night and once in the morning and you're done! Don't believe the stories about wood burning 96 hours! See the article here.

Indoor air pollution is cut to zero by moving the fire and smoke outside, which is vital for people with Asthma, kids and the elderly. However everyone can benefit from not breathing all that smoke and particulates! Your walls and furniture will stay smoke-free and cleaner too.

Simple, clean and efficient, one furnace can heat your house and garage and a shop, spa, swimming pool, hot tub, greenhouse, etc*

NOW comes with an improved rear door latch and an adjustable front door latch plus a fitting standard, for a dry-well (for a probe) or thermometer and a neater, better seal around the chimney PLUS the automatic damper on our fan and a chimney cap!
