When deciding between an indoor and outdoor wood boiler, several factors come into play. Indoor wood boilers, though more complex to install due to additional components like expansion tanks and pressure release valves, are ideal for those with limited outdoor space and offer higher efficiency since they are not exposed to extreme weather conditions. They lose less heat to the environment, resulting in lower fuel consumption. However, they require more frequent maintenance and refueling, and handling wood and ash indoors can create a mess. Having a wood boiler inside your home may affect your indoor air quality along with potential risks of fire thus increasing insurance rates.
On the other hand, outdoor wood boilers have a simpler installation process and larger fireboxes, allowing for longer burn times and less frequent refueling. Maintenance tasks are more convenient as they are performed outside, keeping your home cleaner. However, they can lose more heat due to exposure to the elements and the need to transport hot water through underground pipes, potentially leading to slightly more wood burned.
While indoor boilers have a higher initial cost, their efficient operation can lead to lower operating costs over time. Conversely, outdoor boilers generally have a lower initial cost but may incur higher operating costs due to less efficient operation. Ultimately, the choice between an indoor and outdoor wood boiler depends on your specific needs, space availability, and priorities. If you have limited outdoor space, an indoor wood boiler might be the best choice. If you prefer less frequent maintenance and have ample outdoor space, an outdoor wood boiler could be more suitable.
