Energy Independence
For over 33 years, AHS solid-fuel heating appliances have provided homeowners with energy independence by offering high-quality, long-lasting solid-fuel home heating options. By choosing to heat your home with an AHS Wood/Coal Boiler and domestically-produced solid-fuel, you are choosing energy independence!
AHS Wood/Coal Boilers are designed to use independently or as an add-on to your existing hydronic heating system, and burn either air-dried wood, or anthracite coal in buckwheat or Pea sizes.
Safety & Reliability
AHS Wood/Coal Boilers are constructed of heavy 1/4″ steel plate, reinforced with 3/4" steel rods and welded by experienced and certified welders to ensure safety and durability. For additional safety, a 30 PSI pressure relief valve is included with every AHS Wood/Coal Boiler. AHS Wood/Coal Boilers also feature 2000-degree firebrick and heavy Rolla Grates™ and doors for increased longevity and performance.
Are Alternate Heating Systems boilers insulated?
The AHS Wood Gun™ and Coal Gun™ are fitted with insulation and sheet metal covers as standard equipment. In most Multi-fuel installations, we assume that you are installing the unit in a basement or other space that will benefit from the heat radiating from the boiler itself.
What is an updraft boiler and what is a downdraft boiler?
Updraft and downdraft refer to the way air passes through the boiler. In updraft boilers the chimney is what creates the draft and air movement through the boiler is always either sideways or up. In downdraft boilers a fan is used to create airflow and the air is actually pulled down through the boiler before exiting the boiler and going up the chimney.
The AHS Wood Gun™ versus Competitors
Unlike the competition, the Wood Gun™ is available in both carbon steel and stainless steel models. Carbon steel models, the standard across the industry, are less expensive than stainless models but more vulnerable to corrosion and durability issues. The expected lifespan of carbon steel boilers is 10-20 years. The lifespan of stainless steel units, on the other hand, is yet to be determined. There are currently AHS stainless steel Wood Guns that have been in operation for 21 years with no sign of deterioration. Stainless steel models can burn a wider variety of wood, both in moisture content and species. Both models of Wood Gun™ have much longer burn cycles and operate at lower exhaust temperatures (an indicator of total efficiency) than our competitors' units. Also, all Wood Gun™ boilers may be installed in an outbuilding without a traditional chimney because they create their own draft. In general, AHS wood gasification boiler design is superior to our competitors' in both quality and durability. Most of our competitors in the wood gasification market only focus on the residential segment. We offer an expansive product line that includes larger boilers aimed at the mid-level commercial as well as the residential market. In comparison to similar offerings by our competitors, our carbon steel / Stainless Steel Wood Guns are competitively priced across the board. The bottom line is that the Wood Gun is less expensive and more durable than any of our competitors' products.
Alternate Heating Systems are UL and CSA approved
Currently, the Wood Gun™ is listed under CSA Standard B366-M1979. Generally, the CSA and UL listings are interchangeable. Most states or municipalities that require boilers to be listed specify only that the boiler be listed by a nationally recognized and accepted laboratory. We chose the CSA listing over the UL in this case in order to comply with some Canadian codes. We are in the beginning stages of obtaining UL listing for our entire AHS product line, www.ul.com | www.csa.ca/cm/ca/en/home
Alternate Heating Systems Products are built and tested to the ASME
standards: www.asme.org/
Sizing
It is important to choose a solid-fuel heating appliance that is correctly sized for your home / Business, and when it comes to boilers, bigger is not always better. A slightly undersized solid-fuel boiler will generally require short, hot fires which burn cleaner and more efficiently than the slow-burning or smoldering fires generated in an oversized boiler. The estimated heating capacities of Alternate Heating Systems Wood/Coal Boilers are:
- 1,500 – 3,500 square feet ( Models E 100 and E140)
- Up to 4,000 square feet (Models S130)
- 4,500-8,500 square feet (Models E180,E200 and S260)
- 15,000 Square feet and above ( Models S500 and S1000)
In addition to square footage, some of the factors that may affect your heating needs are your home / Buildings age, design, and geographic location (climate). Other factors to consider are your chimney’s draft strength and whether you plan to burn wood or coal as your primary fuel source. For assistance with determining which AHS heating appliance is right for you, please contact your local AHS Tradesman, or you can contact us directly for recommended sizing.
Warranty
Alternate Heating Systems Wood/Coal Boilers are quality backed with a 6 year limited warranty on materials and workmanship for our Carbon Steel models and 20 year on our Stainless Steel models. Castings, electrical, gauges, relief valves and coils are backed by their manufacturer's warranties. Firebrick and gaskets are not warranted. A copy of the AHS warranty is available in every AHS Installation, Operation & Maintenance Manual. |
