28 deg outside - 68 inside , NO HEATER REQUIRED

Thanks to the magic of the finished insulation & a few gallons of warm water, Its now 68 deg F inside while 28-31 deg outside. Other then my appliances tv, VCR & body heat - no gas or electric heater is present.

Don't try this in your RV .....

You will freeze to death !!....

Remember just add a little insulation to the floors, walls & ceiling
