When talking about tankless water heaters many questions come up and hopefully I will be able to answer some of these questions. I will try to keep it simple.I will be adding more information to the article as questions are asked so if you having any questions please let us know so that they can be answered and added so others like yourself may find out easily. Thank you!
Does a tankless water heater give instant hot water?
No, a tankless hot water heater does not produce instant hot water. In this regard a tankless is like a traditional hot water heater without the tank. When a fixture or faucet is opened a demand for water is needed. This need of water activates the tankless water heater to turn on producing the temperature of water that is set by the heater. The water is then heated to the temperature and will stay at that temperature until the demand for water is shut off.
The time that hot water takes to get to the fixture will depend on how far the fixture is away from the heater. The time is usually around 30 seconds but could take up to a minute. This leads up to the next question.
Can I use a recirculating pump on my tankless water heater?
The answer to this question is no. The tankless water heater has to sense the demand of water to actuate. Recirculating pumps sense the temperature of the hot water and turns on to circulate the water. This can cause issues with the tankless water heater which will cause the heater to either work all the time, not at all, or cause malfunctions.
Types and brands of tankless water heaters
Tankless water heaters come in different types: propane (LP), natural gas, and electric. The prices vary between the types and brands.
