Heating when the power is off.

Those 20 year old hoses might be better than the new ones we are sourcing now.

That also reminds me that I have some hoses in my caravan that are at least 15 years old and need replacing. They are copper tube with rubber lines in spots for easy connections.

At any rate, I am sure the hoses from a solid caravan/motorhome or gas supply center would be good quality and much better than the ones I have purchased from sporting goods store camping sections.
