You can use a tankless water heater with well water, but you will have to consider the temperature of the incoming water, the water pressure from the well, and whether your water is hard or has a lot of sediment.
In this manner, are tankless water heaters less likely to leak?
These are all added advantages of having a tankless water heater. But most importantly, it is less likely to leak compared with its tank counterpart.

Do tankless water heaters get calcium build up?
Properly maintained tankless units can last 20 years or longer, compared with an average of 8–12 years for an electric tank-style water heater. … The heat energy in the tankless water heater separates the calcium from the water, creating calcium deposits that can accumulate on the heat exchanger.
Do water softeners ruin water heaters?
When a water softener system is installed, it removes the “hard” minerals and replaces them with “softer” ones such as sodium. Soft water can actually corrode the water heater anode faster. … So if left alone, a water softener system can actually shorten the lifespan of a water heater.

How many gallons per minute do I need for a tankless water heater?
The best sizing factor for a tankless water heater is its flow per minute rate. A 3.2 gpm, tankless heater can heat 3.2 gallons of water per minute, which is roughly enough to provide hot water to a shower and a sink. To find the correct capacity, add up all of the fixtures that you expect to use at the same time.
What is bad about tankless water heaters?
In addition to high upfront costs, tankless water heaters have several other disadvantages compared to tank-style water heaters: they take longer to deliver hot water. the water temperature is inconsistent when multiple outlets are on simultaneously. they cannot provide hot water during a power outage.
What is the downside of an electric tankless water heater?
The primary disadvantage of on demand or instant hot water heaters is the upfront cost. The smaller units that you often see won’t produce enough hot water to serve most households. They’ll only serve one faucet at a time—a problem if you want to shower while the dishwasher is running.
