Tips for Choosing a Tankless Water Heater


When you purchase a tankless water heater, a lot of research and calculating must go into it before making the purchase. Before purchasing a tankless water heater, make sure you know exactly what you want, and what your expectations are for the product.

First off, make sure that you are aware that the cost of purchase and installation for a tankless water heater are quite a bit more than a traditional tank model. However, you will see savings in the long run. A tankless water heater, on average, can last up to 20 years, and since you can replace the parts easily, they can even last longer. With proper maintenance, sometimes you can get up to 30 years use out of one. A traditional tank model only lasts about ten years. Within the first month or two you will start to see savings as far as energy costs go, and a cheaper power bill since far less energy is required to run a tankless water heater than a traditional tank model.

You need to determine if you want to go with a natural gas or propane heater, or with a electric model when purchasing a tankless water heater. Although a gas or propane tankless water heater is better than an electric tankless water heater, you may want to consult with a plumbing contractor before making this decision, as there are many different variables involved. For a natural gas or propane model, you must have the proper electrical connections in order to operate the sensors and switches. You may end up needing to install a separate circuit breaker in order to get this to work. If you decide to go with an electric tankless water heater, your house’s electrical set up must be able to provide the proper amperage, voltage, and have the proper circuit breaker. Electric tankless water heaters use more energy than natural gas or propane heaters, so you won’t save quite as much on your power bill if you choose this route. One way to determine if you should go with a natural gas or propane tankless water heater or an electric tankless water heater is to check out the long term utility rates in your neighborhood or city. Just because natural gas or propane tankless water heaters are traditionally better doesn’t mean they are better for every home, or even more cost efficient. One drawback to having a gas tankless water heater is that it needs to be serviced about once a year. Not only that, but it also emits greenhouse gasses, which are obviously not good for the environment. The final drawback is that your water bill will probably increase a bit since these systems must be on and operable for a bit before they actually start to release hot water.

When deciding on what brand and price range to spend on your tankless water heater, you should know the standard ground water temperature of your neighborhood or city. It goes without saying that ground water temperature is going to be warmer in Florida than it is in Alaska. If the groundwater temperature is colder, the tankless water heater needs to work harder, and it may benefit you in the long run to invest in a more expensive unit.
