vented vs. non vented

[JSK76]

I have been using a blue flame non vented heater for the last 5 years and I get condensation on the windows and the house has a humid feel. I have a vented heater that I'm thinking about installing but before I go threw all the work I would like to know if people with vented heaters still have moister issues?

I fish with 5 open holes so I would like to know how much moisture is from that and snow melting on the floor from my boots. It would be great to hear from someone who has had or fished in both. I really don't want install a vented but if it make a big difference I would.

JSK your moisture is from the gas being circulated back inside the house, with a vented heater the fumes get routed outside. It is very dangerous to be inside a building that has a non vented heater. They are legal to sell in Minnesota but illegal to install in a house. Think of your fish house as a house you live in on land, it is not worth the risk of someone loosing their life go the extra step spend more money and instal a chimney or by a direct vent heater!

Moisture is a product of combustion and with a direct vent heater it is vented to the outside. I get a little frost and ice on the windows and doors with my direct vent, but nothing on the ceiling or walls.
