Stiebel Eltron Tempra 24 Plus Tankless Water Heater Review

DIMENSIONSL 21.5 x W 19.5 x H 8.8 inches

A tankless water heater is an excellent investment if and when you find yourself in need of a new hot water heater. Traditional hot water heaters are inefficient and wasteful; they require you to have a huge tank of water, kept constantly heated, whether you are in need of hot water or not. Just consider how much energy is wasted keeping all that water hot in the event that you might need it.

With a tankless system, water is heated on demand. When a hot water tap is opened, the tankless system utilizes a coil or a hot spot over which the water is run and heated before coming out of your faucet. These systems are highly efficient and take up a fraction of the space that a regular water heater does.

Considerations when choosing the best tankless water heater

When deciding to buy a tankless water heater, you will want to consider a number of factors. Firstly, the way in which your home is powered (gas or electricity) will determine what type of tankless water heater you buy, but it will not determine the “strength” of water heater you need. To determine what kind of flow rate you need to keep up with your daily needs, you will need to take an inventory of all the appliances that use hot water. Then, add up all the average flow rates of these appliances. This will give you a rough idea of how many GPM (gallons per minute) you need to meet your needs.

You will also want to utilize the services of a professional electrician or HVAC specialist because there may be some retrofitting needed for the tankless system to be properly installed in your home. These systems are quite a bit more complex than a regular water heater, meaning that more goes into the installation that just plopping a new water heater down and hooking it up. You will likely need a professional to install all aspects of your system to help ensure that it is done safely and properly.

Tankless water heaters make sense for many families for a wide range of reasons. The most important reasons that people choose to go tankless is that it reduces their carbon footprint by reducing the amount of energy a family uses to get hot and comfortable water. As we learn more about global climate change and our impact on the environment, it makes sense that people are looking for more efficient appliances to meet their basic needs.

Not only do you save energy with a tankless water heater, you also save money on utility costs. Some tankless units use as little as half the energy that a standard water heater requires. But this does not require you to sacrifice long hot showers or water pressure. A high-quality, whole-house tankless system like the Tempra 24 is perfect for most families, even those with higher-than-average hot water needs.
