9 hours of heat out of a PUNY Wood Pro 2.0 stove - plus stove review

[allan5oh]

Stove - wood pro 2.0
adv space - 2.0 cu ft
Actual - 1.1 cu ft only 10" deep usable space
Flue - about 14'
Wood - debarked American elm fully dry unknown mc
House - 1300 sq ft bungalow half renovated
Location - winnipeg mb
Stove is in the SE corner. Thermostat is in the middle of the house.

The stove itself isn't a bad stove for the money but there are many negatives:

- the firebox is VERY small
- fan doesnt live long
- firebrick is an odd size
- prone to smoke spillage regardless of draft
- can be a little stubborn on cold starts

But it is good value and does throw the heat. Real nice secondary flames as well. It's also fairly easy to get the type of fire you want. A bright radiant one (less efficient) or a darker blue/purple flame (more efficient).




The primary intake at the bottom needs to stay clear yet you only have 10" or so from it to the rear firebricks. That SUCKS.


About 1.5" of coals with a trough right down the middle. I think this is key to maximizing burn times.

9 pm
Outside temp -6c
indoor temp 22c
Stove temp 300f - it reads low
16 lbs in 3 pieces of American elm about 102,000 btus put in the stove east west, primary air pushed all the way in. For this wedge shaped pieces are better. It is stuffed pretty good but could fit more if the pieces were longer.
Half an hour later we are in business.

10 pm
Indoor temp 21.5
outdoor temp -7c
Stove temp 280f
Decent secondary burn and some blue flame

Sorry for the pic quality
11pm
Stove temp 320f
Outside temp -7c
indoor temp 22.5c

mostly blue flame. Front log is coaled. I would say we are hitting max btu for the load 2 hours in.


12pm
Stove temp 300f
House temp 23c
Outside temp -9c

All blue flame. 2nd log is mostly gone. Definitely past peak btu.

6 AM
House temp 20c

9 hours after the load the stove is still throwing heat but there isn't much left. Maybe 3 handfuls worth of coals

Now I understand fully that some of you have castles and you can't heat your house on coals. What really is burn time or load time? That depends on so many factors. I would say maximum 5 hours burn time with this stove.

But I think the keys to getting max burn/heat time - especially on a non cat stove - depends on volume and doing that "trough" trick above

Nice description of your routine. Some similarities to my home in that you have your stove located in the same corner as well as the thermostat location. Sounds like you are getting the job done. Good read.
