We had a crawl space under ours.
We finally hired people to finish the space and install a variety of shielding and bring the thing to code. All of it.
I dont do confined spaces and need sedation when in them at the hospital. I had a mill accident years ago in which I was not sure if I was going to survive that little crush. Fortunately several people were paying attention.
Everything went out the wall above the space with the exception of the new sewer that got installed.
We cleaned that dryer hose among other things several times a year. Its not allowed to try and burn us down.
HOWEVER...
Wife complained for YEARs that stupid mains junction box in our bedroom wall was buzzing bad when the house was juicing off the pole in terms of gulping electricity. Told her forget it, its 50 years old what do you expect?
That was ignorance talking on my part. I should have known better.
The electrician came to rebuild and replace the mains one day and told us we were on our way to a double fatality house fire once the service wires from the poles going into the top of the box itself ate through the insulation. We were at times pulling 90 amps. The box was only coded and built to hold 50 amps. So it was slowly eating through and will have eventually torched our place with us in it.
We installed a 200 amp mains and beefed the :
: out of it. I think we also installed two inch thick stranded copper from Meter above it to the box so that the meter would not feel the heat and spin fast anymore when the house pulled on it. Stuck a 12 foot single pole ground copper into the ground below. Fused the lot and attached a generator patch among other things. Over built.
No more buzzing. Just a pleasant hum when its drawing what it needs all at once for everything.
Where I am now the greatest danger is oxygen. Poof. At least I will be patting off the smoking clothes when I show up in St Peters at the Golden Gates. It wont take long at all.
