Tankless Water Heater - Question

TheProfessor · 06-07-2020, 07:13 PM

So neighbor puts in a new propane tankless water heater.
To save money over a regular tank water heater - gas or electric.

The neighbor though wants instant hot water at all faucets. So some sort of circulator is put in.

So to get instant hot water at all faucets with this tankless water heater - is the tankless propane water heater running all of the time?

Not seeking any information on other types of water heaters. Just the question above concerning my neighbors tankless water heater set up.

Does the tankless propane water heater have to run all of the time to get instant hot water at all faucets?

If so, is the neighbor saving any money?
