| How do I perform an above ground (winter) installation? |
|
|
Use the ThermoPEX® System and a temporary raised base (shown above).
Quick and easy, temporary, above ground installation any time of year, giving you time
to decide the best possible location for your furnace, without having to worry about
frozen ground conditions or snow cover. The ThermoPEX® System is an all inclusive package with
return and supply lines, insulation, and a protective waterproof (and temporarily weatherproof)
jacket all in one pipe, and
may be buried underground in the spring or summer when it's convenient for you.
If ThermoPEX is installed temporarily above ground, provisions should be made to prevent possible risk of fire coming into contact with the ThermoPEX. ThermoPEX is constructed of materials that can burn and transfer a fire. Do not cover the ThermoPEX with combustible materials like straw, hay or leaves.

| Who is Central Boiler? |
| Central Boiler is the leading manufacturer of outdoor furnaces in Northern America.
Founded in 1984 and
based in Greenbush, Minnesota where the winter temperatures can drop to 59 degrees below zero,
we know the value of safe, efficient heat. |
| What is a Central Boiler outdoor furnace? |
| It is a safe and efficient way to heat your home. The Central Boiler outdoor furnace is designed
to look like an attractive storage building and is installed outside, away from the home or
building being heated. A water jacket surrounds the furnace firebox and the heat is transferred
from the wood fire to the water. |
| How can a Central Boiler outdoor furnace heat my building(s) and water? |
| A water jacket surrounds the furnace firebox and heat exchanger, and heated water is circulated to
the home or building through insulated underground pipes -- an efficient way to move heat over distances.
A Central Boiler outdoor furnace is designed to work with any existing heating system.
Water-to-air or water-to-water heat exchangers or direct circulation conveys the heat into
the structure's forced-air furnace, boiler or radiant floor heating system. This allows you normal
thermostatic control. Central Boiler outdoor furnaces can provide heat for all your domestic hot water
by adding a water-to-water heat exchanger, and you can save even more per month! Central Boiler outdoor
furnaces also have the ability to heat multiple buildings, such as a garage, workshop, shed, greenhouse, or barn.
It can even be used to heat a swimming pool or hot tub. |
| What are the advantages of a Central Boiler outdoor furnace? |
| The Central Boiler outdoor wood furnace removes fire hazards from your home or building because all of the burning
takes place outside. An outdoor wood furnace won't affect your indoor air quality and
can alleviate respiratory and allergy problems caused by indoor wood burning. Current
owners of Central Boiler outdoor furnaces are using up to 25% to 70% less wood compared to other
heating alternatives. Since Central Boiler outdoor wood furnaces can burn larger pieces of wood they can dramatically reduce the time you spend preparing wood.
Thermostatic control provides your home with even, steady heat. |
| Is wood burning bad for the environment? |
| A wood heating system is the right choice for the increasing number of consumers who are
concerned about our environment. Wood is a totally renewable resource, which, when burned,
results in no net carbon dioxide increase and can help reduce your carbon footprint. On the other hand,
fossil fuels, when burned, release carbon dioxide which otherwise would stay trapped in the earth.
The burning of fossil fuels causes a net increase in carbon dioxide, which is believed to be responsible for the
heat-trapping greenhouse effect. When heating with wood rather than fossil fuels, you
actually achieve a net reduction in greenhouse gas emissions. In addition, harvesting firewood has
a pruning effect on forests, which allows new growth to flourish. The wood you burn likely comes
from your local area -- it's not imported and not subject to price increases due to events outside
your control, as is the case with oil.
|
| How long will the furnace last? |
| The life of your furnace depends upon proper maintenance. With proper maintenance your furnace
will give you many years of dependable service. |
| How long is the warranty? |
| An optional 25 year limited warranty is available on outdoor wood furnaces that are registered at the time of purchase (includes a corrosion coverage). Central Boiler leads the industry with its commitment to stand behind its outdoor wood furnaces. 25 year warranty not available on Pallet Burner model.

vented, which means they are safe. |
| Is there a lot of heat loss when the unit is outside and it's below 30° F? |
| The units are highly insulated with air tight waterproof urethane insulation, the same insulation used on high efficiency water heaters. |
| Can I connect a Central Boiler outdoor furnace to a forced air heating system? |
| Yes, more than 65% of all installations are connected to existing forced air heating systems. |
| I only have baseboard electric heat. How can I use a Central Boiler outdoor furnace? |

Consult your dealer for other hydronic and space heating options. |
| Can I heat my domestic water with a Central Boiler outdoor furnace? |
| Yes, with the use of a domestic water heating kit that uses a water-to-water heat exchanger. You can turn off your hot water heater and save even more money per month! |
| Can I connect a Central Boiler outdoor furnace to a pressurized heating system? |
| Yes, in one of two ways: By connecting it directly to the existing system and depressurizing it or by
the use of a water-to-water heat exchanger the heat can be transferred from one system to the other. |
| Should I consider radiant heat? |
| Radiant heat installed under new or existing floors can be a great way to heat your home.
Radiant floor heat an efficient way to transfer heat. However, it is important that you design
the system correctly. |

| Can I use an outdoor wood furnace if I live in town? |

exhaust and other pollution already puts excessive strains on the air shed. But in suburban,
small town, and rural areas, an outdoor furnace makes good sense. If you choose to install your furnace
in a densely populated area the stack height should exceed the rooflines of existing homes.
|
| Does the furnace come fully assembled? |
| Yes. Like most major appliances the unit only requires installation. |
| Can boilers explode? |
