I bought that little bator....cost like $20 with shipping....it's molded plastic, no insulation at all. Has hollow legs to put water in. Cat tipped it over and the eggs were on the floor for a while. Put them back in. We heat with wood and the furnace is set to come on when it hits 62*....soooo my room temps can be anywhere from 62 - 85....and the bator was on a small box near the floor so it probably never gets anywhere near the high the thermostat reads. I still got 50% hatch rate...which is great when you only have room in the bator for 2 eggs....I will admit that the 7 watt bulb kept it a constant 100 degrees when I checked it...but I didn't check it in the middle of the night, only after the fire was started,etc. (creature comforts before chicken duties, sorry) So I am not sure that the room temp has to be as high as you keep your room....as long as the incubator has the power to keep the internal temp constant, it shouldn't matter what the room temp is...below 65 probably isn't a good idea, but most people keep their house 65 or above.
My information is based on the article from Practical Poultry magazine and it works for me.
Certainly things differ with each individual but I would be very disappointed to have a 50% hatch rate. While the thermostat may read 65 there are warm spots and cold spots in most homes. Too, incubators have instructions and I do recommend following them since the manufacturers test them in varied situations.
Also the altitude can have an affect on hatch and temp and humidity as well I think.
My first hatch with an old incubator yielded one chick. The person who loaned it to me had, according to them great hatches. They heat with a pellet stove. We all need to work out our system and what works for us. That's why I say never give up.
