What temp should outdoor boiler be set at?
between 160° and 180° FIdeally, an outdoor wood boiler maintains a temperature between 160° and 180° F, controlled by both the fire and exhaust system. Once the furnace reaches 180° F, the fan giving air to the fire turns off and closes the damper, which in turn lessens the flames and temporarily prevents the wood from burning further.

How does a central boiler work?
How a Central Boiler outdoor furnace works 1 The Central Boiler outdoor furnace is located outside, typically 30 to 200 feet (but as far as 500 feet) away from your home or building, and works with any existing heating system. 2 A water jacket surrounds the furnace firebox and heat exchanger, and heated water is circulated to your home or building through insulated underground pipes -- an efficient way to move heat over distances. 3 The 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, radiant baseboard or radiant floor heating system. This allows you normal thermostatic temperature control. 4 The outdoor furnace can provide heat for all your domestic hot water by adding a water-to-water heat exchanger. You can turn off your hot water heater and save even more money! 5 The outdoor furnace has the ability to heat multiple buildings, such as a garage, workshop, shed, greenhouse, or barn -- without using other heating sources. It can even be used to heat a swimming pool or hot tub.

What is the delta T of a wood boiler?
So the water's gonna be coming back here at 150 degrees, and then coming into this plate exchanger. Now the wood boilers are generally running at about 180 degrees, the water coming back is about 150, and you're gonna lose about 20 degrees when it's trying to heat. So this is gonna be about 160. So in aspects, you've got a delta T of 130 or 30 degrees. That is a large enough delta T to have a good heat exchange rapidly.
What is aquastat on boiler?
The aquastats that are mounted on the indoor boilers are usually a little bit more square than a rectangle here , but they're fundamentally the same. They have a little probe that monitors the temperature of the inside of the boiler, and they have a little gauge which tells you the temperature that you would want it set at the high limit, referring to 180 in the case. And then inside, there's a little paddle where it'll allow you a 10-degree differential.
How does Crown Royal stove work?

What is an EZBoiler outdoor furnace?
The EZBoiler outdoor furnace is a natural draft system. It burns organic fuel and heats the water that is in the water jacket. The furnace water jacket completely surrounds the firebox. Water is pumped through an insulated line that is buried in the ground and attaches to an indoor furnace coil that is mounted in the duct work of your home. When your home calls for heat, only the furnace blower turns on, forcing air through the furnace coil and heating your house with the energy created in your outdoor wood stove.
Why use an outdoor furnace over an indoor stove?

Why is a stove water tank bigger?
A larger water tank would allow the stoves to cycle on and off less frequently; however, during milder weather, the time period between cycles would become great enough to result in a smoldering pile of ashes and wood that struggles to come back to life when needed. It would also cause more smoke and damaging creosote formation. Our stoves are designed to produce a smooth, steady transfer of heat that keeps your home warm and comfortable 24 hours a day.
What happens if you draw heat out of the water?
If you start drawing heat out of the water too soon, the stove will not be able to catch up, and creosote will probably clog your chimney. Keep the water pump (s) operating, but don’t turn the indoor thermostat for the outdoor stove up until that operating temperature is reached.
