A small amount to keep the pilot light going.
You are running the water heater out of hot water faster than it can heat the incoming cold water.
A tank water heater stores and heats a large amount of water continuously, while a tankless water heater heats water on demand without storing it. Tank water heaters are typically larger and have a limited supply of hot water, while tankless water heaters are more energy-efficient and provide hot water instantly.
means you are running out of hot water
Please be more specific ... heater gives off heat, then cold air OR The heater fan runs for awhile then stops running
Yes, you can transport a water heater while it is laying down, but it is recommended to keep it upright to prevent damage to the internal components. Transporting it upright reduces the risk of leaks and ensures the water heater functions properly.
I am going to assume that you are pondering why the heater only maintains heat while the engine is running. The answer is quite simple. The engine uses a combination of anti-freeze and water to help keep it cool. The water is circulated by a water pump. The hot water moves through the heater core, which is a small radiator. The blower draws air through the fins of the heater core and heat is pulled from it. The water pump is usually belt driven, and the engine must be on in order for the coolant to circulate.
The key differences between a heat pump water heater and a gas water heater are the energy source they use to heat water. A heat pump water heater uses electricity to transfer heat from the air or ground to heat water, while a gas water heater burns natural gas or propane to heat water. Heat pump water heaters are more energy efficient but may have higher upfront costs, while gas water heaters are typically cheaper to install but have higher operating costs.
The key differences between an electric tank water heater and an electric tankless water heater are that a tank water heater stores and heats a large amount of water continuously, while a tankless water heater heats water on demand without storing it. Tankless water heaters are more energy-efficient and space-saving, but may have limitations on the amount of hot water they can provide at once.
The meaning of running water is that the water is moving and not standing still. Running water is what comes out of a faucet while water in a bowl is just called water.
The kitchen sink is the farthest appliance from the water heater. Have a plumber install a circulating pump under the sink for instant hot water.
A tankless water heater heats water on demand, while a tank water heater stores and heats a large amount of water continuously. Tankless heaters are more efficient because they only heat water when needed, while tank heaters can waste energy keeping water hot. Tankless heaters are generally more efficient for providing hot water in a household.
Is it a Fast Food Establishment? If it is, then Yes. I once worked for a Fast Food establishment that was shut down for a day because the hot water heater stopped working while the inspector was there.
