Tankless Water Heater Installations

- Endless Hot Water Tankless water heaters heat water on demand, they do not run out of hot water. This type of water heating system can be useful for large families or for homes with larger hot water demands – for instance, homes with a soaking tub or spa system are often good candidates for a tankless system. If you are unsatisfied with your current water heater, consider converting to a tankless water heater system. While traditional storage water tanks are compared based on gallon capacity, recovery rate and first-hour rating, tankless hot water heaters are compared based on flow rate. As long as the home uses hot water at a flow rate below the tankless heaters maximum flow rate, there is endless hot water.
- Important to note: Tankless units do not provide instant hot water as hot water still takes time to flow from the unit to its destination. If you are interested in instant hot water call and ask one of our experts about recirculation systems. Depending on the configuration of your plumbing we may be able to install a circulation system for you.
- Energy Efficient When compared to storage tank-type water heaters, tankless water heaters save 20% to 40% on energy. The most efficient tankless water heaters have an efficiency of 92% to 95% when compared to traditional gas storage tanks, which have a maximum efficiency of 62%. Tankless units typically have an energy efficiency of more than 80%. The reason why tankless water heaters save the most energy because water is not constantly heated, cooled, and re-heated as it is in a storage tank.
- Long Life Expectancy If maintained properly tankless water heaters can last twice as long as a traditional storage tank. The average life expectancy of storage tank water heaters is approximately 8 to 12 years.
- Space Saver Tankless water heaters are much smaller and are more versatile for installation. You can even hang them on the wall or locate them outside and they are about 1/4 of the size of a tank-type water heater, this can free up space inside your home or garage.
- Sizing a Tankless Water Heater In our experience flow rate is the most important factor in sizing your tankless water heater.
- Tankless units heat water on demand (when you open your faucet) unlike traditional storage tanks that heat when the tank temperature drops below a set point.
- Tankless water heater sizes are measured by their per-minute flow rate rather than by their gallon capacity. Most tankless water heater manufacturers offer several models to meet different flow rate needs. Flow rates for most major brands range from four to eight gallons per minute.
- Typically, the smaller four to five-gallon per minute water heaters are suitable for smaller apartments and small one bathroom homes.
- For single-family residences with two bathrooms or more, we strongly recommend installing a six to eight-gallon per minute unit. These tankless water heaters are designed to service two or three applications at the same time. For very large homes, restaurants, or other commercial applications there are many other options including installing multiple tankless units in series.
When it comes to your home and getting a tankless water heater, it is always recommended that you have a licensed water heater technician inspect your current situation.
