How To Choose A Tankless Water Heater
Tankless water heaters are a great alternative to the traditional storage-tank design. Unlike those traditional water heaters you see in most older homes, tankless models don’t store hot water. This is why there’s no need for a tank…hence the moniker ‘tankless’. When hot water is needed, a flow sensor turns the burner on which, in turn, heats the water to the desired temperature.
Tankless water heaters use less energy than traditional storage-tank water heaters and can save you money over the course of a year. When shopping for a tankless water heater, keep the following points in mind:
1) Location, location, location
Because a tankless water heater heats the water on-demand, it is greatly affected by the temperature of your groundwater. Here’s an example:
A tankless model installed in a Florida home will put out 7.0 gallons of hot water per minute. That same model installed in a New England home will only put out 4.0 gallons of hot water per minute. Because of the differing temperatures of the ground water at different locations, the Florida model only had to heat the water 44 degrees while the New England model required a 77 degree jump.
When considering a tankless water heater, it’s always best to factor in your coldest groundwater temperature in order to calculate the gallons per minute and, thus, the model you’ll need.
2) Flow, flow, flow
Accurately estimating your flow is a necessary step in choosing the right model of tankless water heater. Undersizing a tankless water heater is a common mistake than can lead to less-than-optimal – and less-than-desirable – results.
When trying to decide between models, there are two important features to consider. The first is an oxygen-depletion sensor that turns off the unit if carbon monoxide is detected. The second is a film wrap around the heat exchanger that will cut power if the unit gets too hot.
4) Rebates, rebates, rebates
Many tankless water heater models will qualify for utility rebates or tax credits but you have to do some research first. Check the Database of State Incentives for Renewables & Efficiency at www.dsireusa.org.
For more information on tankless water heaters, call Crystal Lake Plumber. We are a fully bonded, licensed, and insured plumbing contractor that experience with a variety of tankless water heater systems. We can help you with the installation, repair, and preventative maintenance on these water heating systems. In most cases, we recommend installing a gas-fueled system as the electric systems don’t save that much in energy costs and take longer to heat up.
Crystal Lake Plumber is proud to install, repair, and maintain the alternative tankless water heaters as well as the traditional tank-storage water heaters. We are also proud to offer other services including faucet repair, garbage disposal installation and repair, reverse osmosis systems, and sump pump installation and repair to much of northern Illinois including Lake Hills, McHenry, Huntley and Algonquin.
