Properly Size Your Outdoor Wood Furnace

admin | September 1st, 2010 | No Comments »

The size of any regular outdoor wood furnace or any EPA outdoor gasification furnace should be matched to the requirements. All wood furnace manufacturers use either a BTU rating or square footage capabilities. Since the BTU’s in wood vary, the only true way to state maximum heating capabilities of an outdoor wood furnace in square feet. Here are some guidelines to follow:

Base Calculations
In Canada and Northern USA, start your calculations by using 75% of the stated maximum square footage. This is usually a safe place to start under most conditions. When you exceed this amount, be very careful in your calculations. Upgrade to the next size of any outdoor furnace or EPA outdoor wood gasifying furnace long before you reach the maximum heating capability.

Ceiling Height
Calculations of an outdoor wood furnace heating ability is always based on new construction with an 8 ft. ceiling. For a 16 foot ceiling consider adding up 40% to 50% to that area.

Basement & Upstairs
VERY IMPORTANT Also add the square footage of the basement and the upstairs and any other area to be heated.

Building Age
The older the building the less likely it is to have adequate insulation and be airtight. New R2000 buildings have lower heating demands on the outdoor water furnace.

Distance From Furnace to Buildings
The better the underground insulation then the less impact from long distances. Some of the better underground insulations loose almost no heat in 300 feet.

Easy Rule of Thumb Solution
Once you pass the 3/4 mark on square footage, consider moving up to the next larger size of outdoor furnace. Over sizing never hurts; it will allow more time between fills. You do not want to regret buying a small wood stove that is maximized.

Problems Caused by Under Sizing
When filling a properly sized outdoor boiler, you would normally add wood either morning and evening, or once per day, depending on the season. If the firebox is too small and it is a really cold night and you are using lots of heat, and most of the fire wood is already burned up; your outdoor furnace may not be able to continue making more BTU per hour than you are using. When you are low on wood in a high demand time, the temperature of the water in your outdoor furnace may drop from 180F to 160F to 140F to 120F. Anytime you are 150F or lower in any outdoor furnace the difference in the temperature between the water jacket and the firebox will cause condensation in the firebox. This condensation can cause steam in the firebox, which will cause a poor fire burn. It may seem like you are gobbling up wood and getting very little heat. Sometimes the quickest way to recover from this is to turn off the circulator until the water reaches 180F, and then the temperature will stay up there. With a properly sized firebox, this will never happen.

Outdoor wood furnace or boiler can solve high energy costs

What if there were a way to provide heat for your home, a way to give you all the hot water you and your family would need for showers, baths, laundry and more – all your family would need to heat your pool, spa, and anything else you wanted to keep warm with a truly efficient, completely renewable resource? What if you were able to help the environment while you were heating your home? What if you could do all this for FREE?

freefirewoodCertainly, there’s the up front cost of the equipment in the beginning, but I’ll ask you to demonstrate to me a heating system that doesn’t demand a substantial initial purchase price. Being able, then, to do everything in the preceding paragraph truly sounds great, does it not? Wood is the resource that matches all of these needs. It is right down the road or in the backyard. Yes, we are talking about wood.

Naturally, you might say that that is old-fashioned and inefficient. That’s not the case anymore. Wood heating has finally come of age. The modern outdoor wood furnaces Alternative Heating & Supply has take advantage of the latest developments in heating technology. Once one is installed outside your home, and using water and heat exchangers, our furnace burns efficiently and cleanly. Normally it can be attached to your existing system to distribute the warm air wherever your home needs it.

Due to the fact all of your fuel, the wood, is kept outside, you will not have the mess associated with indoor stoves. The furnace will burn all dimensions and types of wood, too, even those unsplittable knotty pieces. And, the cool thing is you only have to add to it once or twice a day, even in the coldest weather. That’s terrific, isn’t it? Load it up in the morning and again in the evening, and the unit will do the rest. Normal water heated to 185 to 200 degrees surrounds the firebox, and then courses through tubing to your home where heat exchangers change it to hot air that is dispersed by your present system.

Gas, oil and coal are fossil-based, non-renewable resources. And in the last year, costs for these commodities have soared toward the moon. You know this to be true. Power prices are rising, too.

The environmental impact of these fuels is significant and must be taken into account. The methods used to extract fossil fuels are damaging to the ecosystem. Home systems, unless they are constantly and professionally maintained, are not really efficient burners. And electricity is often produced by coal-fueled plants or by hydroelectric dams that affect our fragile ecosystems.

So, when you take it all into mind, there’s no other source of heating your home to provide you all the advantages of a timber-fueled method. Wood is environmentally friendly, efficient and cost-effective. And with a little extra work, you can get all this at no cost. This is an energy resource which grows virtually everywhere. Areas are frequently being cleared and what remains are excellent for your personal use. Haul it home and you and your loved ones can stay toasty all winter season for the price of a tank or two of petrol.
