When it comes to choosing a tankless water heater, there are a few pieces of information to pay close attention to. These are: fuel type; location, size, and demand; and application.
There are two fuel types for tankless water heaters:
A central concern with tankless water heaters is where you need the hot water. Do you want a single-point system for one bathroom sink or one appliance? Do you want a multi-point system for one room? Or do you want a tankless water heater that works on an entire home?
Each fixture has its own level of demand, so gauge the flow rate of each appliance – a dishwasher requires up to 3 gallons per minute, for example – so it might be a good idea to install a dedicated tankless water heater for the dishwasher alone. Should you want a whole-home system, however, you need to add the flow rates together to get the right number so you can decide how big of a heater to purchase.
Then ambient water temperature comes into play: northern climes have lower average groundwater temperatures, so you’ll need a heavier-duty tankless heater in New York versus Texas, which has higher average groundwater temperatures, in order to heat water to the same temperature.
The final concern for a tankless water heater is its use. There are point-of-use water heaters for single or multiple points in a single room, thermostatic heaters used to keep water hot over long distances, or whole-home systems. What you pick depends on what you need it for.
