efficient wood stove?
Can a wood stove be efficient? Is there a way to increase the
efficiency of a wood stove?
Not everything in our house is high-tech. For those cold winter
days that are neither sunny nor windy we have to have a low-tech
method to warm up the house.
Just because a wood stove is considered low-tech it doesn't mean
that it should be inefficient. We started with a Morsø
stove that was 71% efficient (test according to Autralian Standard
4012) and improved its efficiency by installing a non-standard
flue.
The long and non-vertical stainless steel flue helps to cool down
the hot fumes before they fly away, and hence helps to retain
more heat from the burned fuel in the house interior.
This is especially noticeable when we start the fire. While the
firebox is still cool to touch, the flue radiates plenty of heat.
