It falls out of the sky and you die
you have no heat and car runs normal
Nothing, a steam boat runs not on steam, but on a heat source GENERATING steam. this heat source is usually coal but could be wood or a fossil fuel.
There will be no more gas or oil and we better have another fuel source by then
it runs on propane.
A small through-the-wall or window unit (air-source heat pump) to cool and heat a single room runs about $500 to $1,500 US dollars. A whole-house system with existing ductwork (a typical split system air-source heat pump runs $2,000 to $5,000 US dollars for an average home. Complete installation of a geothermal heat pump (ground-source or water-source) runs $10,000 -$25,000 or more, depending on the length and depth of the underground pipes, soil conditions and other excavation and installation factors. Food for thought - in an older home you may need to hire an electrician to upgrade the electrical panel to 200 amps, which can cost an additional $1,300 -$3,000.
when I turn the heat on nothing happens. But when I cut it to yhe on switch the fan runs. Could it be the fuse are a blown cicurit. And yes my AC works fine.
If the burner fails or runs out of fuel, the hot air in the balloon (that gives it lift) would cool and the balloon would come down to earth.
Most likely need water pump could over heat and damage head gaskets
The engine overheats and parts can melt, crack, even explode (massive expansion due to heat.)
The refrigeration equipment runs constantlty, heating the room. A fridge just removes heat from the inside area and pushes it out the rear coils. Any heat generated by the compressor is added to this.
What kind of heat do you have? Heat Pump? Be glad it runs.
If the lawn mower is run without oil, the connecting rod bearing will heat and score, or even "weld" to the crankshaft, causing major damage.
