Saving Big with a Tankless Water Heater

Did you know that switching to a tankless water heater can save you money on energy costs? According to, by upgrading to a tankless system, the typical family can save more than $100 in utilities every year. That big savings is thanks to the fact that tankless hot water heaters can be up to 34% more energy efficient than a conventional tank unit.

Saving Money: How it Works

The principal behind how an inline tankless unit operates is really quite simple. A hot water fixture valve is opened, and the tankless water heater draws in cold water through the inlet pipe located at the bottom of the unit. As the cold water enters the pipe, the PC board signals the igniter and the exhaust fan turns on. The gas control valve opens, and when an adequate flame is achieved, the igniter shuts off leaving the flame burning.

Cold water passes through the copper coils of the heat exchanger, and depending on the demand amount of the water, the flame adjusts accordingly. In only a matter of seconds, hot water is piped through to the faucets at the exact temperature setting of the adjustable digital controller.

After the hot water valve is closed, cold water stops entering the unit and the flame is extinguished. The exhaust fan continues to run for a few moments before it shuts off, insuring adequate ventilation. There is no perpetual heating and no pilot light, which ultimately saves energy and money.

Start-up costs are higher for the tankless units. However, the price is easily off-set by the lower energy usage of the unit and lower maintenance fees. Tankless units also have about twice the life span of a conventional unit, and there are numerous federal, state and local tax credits and rebates available for those who make switch. All that equals saving big, but the savings aren’t found only in the wallet.

Saving Space

Also known as an inline water heater, or an on-demand water heater, the tankless hot water heater is a small heating unit that can run off propane, natural gas or electricity. The unit is so small in size that it can be easily mounted on any interior or exterior wall throughout the house. They can also be hidden under sinks and inside cabinets, ultimately freeing up highly-coveted closet space. 

Saving the Environment

If the decrease in energy usage isn’t enough to make you consider the switch, there are a few other benefits in going tankless– like helping to save the environment. Most tankless units are made out of recyclable materials, whereas the typical water heater tank just ends up in a landfill.

The hot water is also cleaner when it comes out of a tankless unit. That’s because the conventional storage units build up rust, scales and other deposits, which ultimately ends up in your wash and bath water. And don’t forget one of the best benefits of all: never running out of hot water again!

If you’re considering making the switch to a tankless unit, then you’ll need to hire Howell Services, your friendly neighborhood licensed plumbers in Sugar Land and Katy, TX.
