New, More Efficient Wood Boilers
Filed Under Outdoor Wood Boiler Design | Leave a Comment
Wood boilers are very popular as a heating method using an alternative fuel, in areas where wood is available. One drawback to these outdoor wood boilers is that most designs are inefficient and can cause quite a bit of smoke pollution. This is why it really pays to shop around and get the right unit.
These tiny metal clad sheds with a chimney sticking out of the roof heat water, which is transfered to other buildings such as houses or shops via insulated underground pipes. The hot water is then utilized in space heating and to heat water for use in the house with a heat transfer system.The now cool water then returns to the wood boiler to be heated once again.
Some reports show that an outdoor wood boiler efficiency ranges from 28 to 55 percent. Many indoor wood stoves have a much higher efficiency score of 68% to 72%. This is why in some areas wood boilers are not allowed, due to worries over white smoke and particulate matter they emit.
The good news is that wood boiler manufacturers have been paying attention. They have been working with government environmental regulators to write and meet an new smoke emissions test standard. This means that consumers will have access to new, more efficient and upgraded units. Hopefully, the new wood boilers will be neighbor friendly and produce much less smoke pollution, and at the same time require less fuel as well as have longer burn times per load. This kind odf scenario would be a win win situation, as home owners would have a heating solution that saves them money and causes less of an uproar on the smoke pollution front.
As always, the best idea is to do a lot of research to make sure you don’t end up with one of the older, unimproved models if there is a newer, better wood boiler out there.
Research Before Buying an Outdoors Wood Stove Boiler

While outdoor wood stove boilers are the next generation of wood fired heat, they can have a few trouble areas. Many outdoor boilers are made from low grade materials and use an outdated, inefficient design. Like all major purchases, shopping around is a good idea to get he most value for your dollar. Spend some time comparing the different outdoor wood boilers available online and call a few distributors to ask questions.
Rust and deterioration can be a problem with outdoor wood boilers. To a degree, higher quality materials and design can give your new wood boiler a longer lifespan. One design feature to look for is an internal chimney, rather than an external one. External chimneys will have higher creosote deposits due to lower chimney temperatures and possibly chimney fires which could result in damage to the unit. Another consideration is the length of the chimney on the wood boiler. You may have to budget a little extra to lengthen the chimney pipe to get smoke a little higher above nearby eaves. This is also where purchasing a more efficient outdoor wood boiler to start with can really pay off. Higher efficiency means less smoke. With a taller chimney, an efficient wood boiler and good quality wood, you will reduce the smoke the outdoor wood stove boiler produces.

If you are looking into the viability of an outdoors wood boiler for your home, here are a few reasons to take the plunge and start heating your home with a wood boiler.
1. If you have a good source of cheap wood you can save a lot of money.
You may have wood growing on your own property, or live near a sawmill that will give you scrap wood. You might even buy entire semi -truck loads to get a good deal on wood.
2. A wood boiler can heat your home and your water supply.
Not only can you reduce your heating bill on living spaces, you can also heat your domestic water, your hot tub or your pool at a reduced cost of using natural gas, propane or coal oil.
3. The wood and mess stay outside.
You get the benefits of burning wood, yet the wood chips, ashes and smoke stay outside.
4. Locations with no natural gas lines or nearby standard fuels can heat comfortably with wood.
Even if you are far from normal fuel supplies, you can heat your home with a wood boiler system instead of an indoor wood furnace.
5. Wood is a renewable fuel.
Properly managed woodlands can provide an endless supply of renewable energy. Coal and other oil type fuels release carbon that had been trapped beneath the earth, while burning wood only releases the carbon that is present on the surface of the earth already.
6. Keeping the wood fire outdoors can be safer for some homes.
Having an outdoor wood stove boiler keeps the flames and smoke well away from your house. While it is true that wood stove operation can be as safe as any other heating system, many people would prefer to keep wood fire away from the buildings.
Hopefully these points help you make a decision on whether or not to own an outdoors wood stove boiler. If you are still interested in using wood but don’t want to bother with water lines and a boiler, you may want to consider installing a wood burning stove in your home.
