Dale asked, why install the propane tank in the house.
I have it next to my desk in the house. It's a bit scary, but when it's outside it's scary also. I read that propane tanks are sensitive for cold and warm. (correct me if i am wrong)
And if you leave the tank outside with warm weather and in the cold that thats not very safe then.
It's difficult for me to install the tank outside. In the winter i need to keep the window open to hang the hose outside and i have to climb outside the window to turn the propane tank open and climb back in. See left on the picture. The Propane tank is on the right. I have an propane alarm it's hanging under my desk.
I would like to build an savety box for inside the house where the tank could be placed in. But what material must be used. When a tank explode it has so much force, its scared to 'work like this. But i can't see another option.
I am sorry for my bad English writing. I do my best.
