Can Garden Hose Fit Into Water Heater Outlet

Are the connectors on a hot-water hose the same a garden-hose?

No. However that part you identified is not going to fit a common WH anyway. The connections for most water heaters are 3/4 inch. Some bigger ones are 1 inch.
There is probably some industrial, commercial WH that would fit the big honker you named.

The drain valve normally does connect to garden hose thread.
What I need... A free-flowing 36" hose 100-psi; Female garden-hose connectors on each end. Help?
What are you connecting to what? A female GHT to female GHT is what is used to hook up washing machines. A water heater normally has tapered pipe thread.

Normal home water pressure is supposed to be less than 80-psi. While accessories designed for use there are tested at higher pressures, a constant pressure higher might not be reliable long-term. It sounds more like what you need is something industrial.

How long will this be in service? Two weeks at the camp ground? Two years?
Carrying drinking water? That washing machine hose may give a bit of rubber taste.

A standard garden hose is rarely rated for hot water, so keep that in mind.
no a hose is not the same thread. They are not interchangeable. You didnt mention why your asking this and I aint going to guess .
Good questions... Thanks for asking. Application: Long-term usage of a chemical-injector for irrigation. The injector input/output are male pre-threaded garden-hose connections. Only cold-water, not used for drinking. Standard washer-hoses seem to restrict the volume-throughput. Need a 3-foot least-restrictive hose. Help?
build one whatever size you want buy hose and a couple of barbs and hose clamps. or go to a place that builds hoses. easy!
The only other issue is that garden hoses aren't intended to handle hot or warm water. As a result, you may have issues ranging from extra pollutants in the water to hose degradation. The cheapest option is to simply install a hot line next to the existing cold line. Use the same pipe and fittings as before, but purchase a red handle instead of a blue one. To combine hot and cold, get a washing machine hose. I highly recommend you to ask here https://cornygardener.com/drinking-water-safe-hoses/ for more help.

Cligerson nailed it ........... What the OP describes is a washing machine connection.
