Tips on Choosing

  • Price: You don’t need to spend a lot of money on a water heater if you are purchasing a smaller space. If you are purchasing a large home, then you will need to adjust your budget accordingly to meet the potential demands of a larger house. New purchasers should also prepare because tankless gas water heaters will cost more upfront than electric water heaters.
  • Climate: The colder your climate is the more powerful a water heater you will need. On the contrary, if you live in Florida, you could potentially get away with the least expensive unit even for a large household because the unit won’t have to work as hard.
  • Natural gas is a lot cheaper than electricity. If you wind up with a top unit, you could wind up saving money in the long run. Several customers have reported that they have been using their good water heaters for years which proves they can be very durable.
  • Physical size: Your water heater can be small and lightweight. A compact heater will fit in your storage closet with no problem and you will most likely be able to fit other appliances in there with it.
  • Safety: Consider a water heater with proper safety measures that won’t allow the heater to overheat or freeze. Some heaters come with an auto shut-down feature or a temperature regulator. You could also look into a heater that locks the temperature in place to reduce the amounts of accidents during use.

Factors To Consider

  • Household size: The number of people in your home is a major issue to think about when you’re shopping for a water heater. The number of gallons per minute (GPM) will differ greatly when you’re comparing a five-bedroom home to an apartment.
  • GPM: You can check your shower head to see what the GPM rating is. Showers tend to use the heaviest amounts of hot water of all appliances. It’s smart to check your other appliances as well including your dishwasher, sink, and washing machine. Once you’ve considered each hot water appliance think about how many of them you will use at the same time, and that’s how you will get your total GPM need. For colder climates consider rounding up your GPM need by 75 to 100%.
  • Installation cost: Some of the costs you’ll have to be ready to include the venting construction and retrofitting of your gas line.
  • Hot water for appliances: Unless specifically mentioned, tankless water heaters are not designed to be used in pools. The chemicals that are required to run spas and pools can be damaging to the water heater’s components.

Making The Decision

Now that you have all the information you need to know about purchasing the propane tankless water heater it’s time to make your purchase. Base your choice on the number of gallons per minute that you think you’ll need. Consider the size of your home and the number of appliances you’ll be running at the same time.

Get your budget ready based on how powerful your water heater will need to be.
