The inside of the earth because scientists say that the there is some kind of heat found inside of the earth that is an orange color, so that's what heats the water.
magma
Over thousands of years rain water seeps through cracks in the Earth's crust and collects in underground reservoirs between the crust and the mantle. The mantle heats the water into a super-heated liquid and, voila!, you have a geothermal reservoir!
When the weather is cold, the water or refrigerant heats up as it travels through the part of the loop that's buried underground.
Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
Soil heats up and cools down the fastest. Water heats up regulary and does not cool down for a while. Sand heats up the slowest and cools down the slowest.
Radiation heats the water.
When magma comes in contact with underground water, it creates hot springs, or geysers.

magma. underground lava.
These are vents through which volcanic gases and water vapour escape to the earth's surfaec.Fumaroles are formed when magma heats underground water,it mixes with volcanic gases and the mixture is eventually released as steam.
When the heat from underground heats it up and it turns out to be boiling.

It heats from the celci-di that heats an outdoors calborithm
the water heats faster than soil.

it heats water
A water heater usually heats water stored in a tank and then sends it into the pipeline. A tankless water heater has no tank and heats the water during its passage and so heats the water only when one asks for it.
