What's the best water heater for you? Tanked or tankless? Natural Gas or electric? In this episode, Jordan gives his reasoning on why he thinks the Stiebel Eltron Tempra Plus is hard to beat. (LINKS BELOW)
Unlike their tanked counterparts, tankless water heaters do not use energy when there is no hot water demand from the house. This allows them to be more energy efficient when used in the right application. The electric versions are much better than their gas counterparts when it comes to ease of installation and air sealing after they are installed. Gas versions require both combustion air as well as an exhaust port. Whether they are mounted thru-wall or installed inside with a direct vent coaxial inlet/exhaust, you will have a time getting all of the details right to ensure a well sealed house. The electric version, on the other hand, makes it easy to install anywhere without the need to ventilate.
We decided to install this water heater in the mud room that sits in between the kitchen and master bath. The central location allows for short runs to all hot water taps in the house and reduces waste.
The electric version is also drastically cheaper than a quality gas unit.
One major requirement to consider is the MASSIVE amount of power this thing requires. The 29 shown here requires a 200 amp services into the home and can draw up to 120 amps at full capacity! You will want to plan for this behemoth well ahead of time and make sure your electrical design allows for such a large load.
Would I install it again? Yes I would. But I would also seriously consider a heat pump water heater. They can be more efficient than a tankless, and the current draw is DRASTICALLY smaller, making it easier to retrofit into normal electrical designs. My only hesitation at the time that I built this house was that the heat pump water heaters were new on the market and had some reliability concerns. I need to do more research to see if a heat pump makes sense for my next build, or if the quality concerns still exist.
