In Garland, tankless water heaters are one of the hottest products in the plumbing business. Our Garland plumbers have known about these little gems for quite a long time. We've been suggesting the switch to tankless systems for the last decade. Why should you install one (or more)?
To determine the size and type of tankless water heater system that you should install in your home, calculate the highest volume of hot water flow that you will be using at one time. The easiest way is to determine the number of gallons per minute (gpm) that your common hot water appliances use. Most of this information is available either in the documentation that came with the appliance, by calling the manufacturer, or by looking it up online. If you cannot find this on your own, one of our Garland tankless water heater specialists can help.
For example, if you commonly take a shower and run the dishwasher at the same time you would add these two appliances together to determine the needed gpm rating for your tankless system. If the shower head uses 2 gpm and the dishwasher uses 5gpm, you'd need a total tankless water heater capacity of 7 gpm. This would require two electric models (as they usually top out at 4 gpm or one large gas-fire tankless water heater at 7 or 8 gpm).
