DETAILED REVIEW

Introduction

If you have ever been in a position where taking your bath is a fight because the water is too cold or where you can’t do the dishes because your hands will turn frosty at the first rush of cold water, then it’s time you to get rid of that old tank heater or whatever it is that just can’t provide you with hot water when you need it. And while you are thinking about that, you should also plan on how to make provisions for a better heating system.

As far as modern technology is concerned, the best solutions you can ever come up with to meet your hot water needs is a tankless water heater.

Tankless water heaters are becoming increasingly popular and it’s not difficult to see why. Tankless water heaters are important for households for two major reasons- they help prevent the wastage of water and also stop your bills from skyrocketing. Perhaps they do not require large tanks and so do not take up as much valuable space; this makes them more practical than hot water tanks for small homes.

But then, finding the right tankless water heater can be somehow overwhelming especially if you’re a first timer or you’re looking to replace your current heater with a more efficient unit.

Luckily we’ve done all the hard work for you and come up with a list of the best water heaters in the market. The Stiebel Eltron Tempra 36 plus Tankless Electric Water Heater is one of such products and today, we are going to be looking at what the device has to offer.

Installation

Installing the Tempra Plus is easy not just because the manufacturer claims so but because it truly is, as attested by various customers. This unit involves a much simpler set-up than its counterparts. It requires a small space and can be plugged an anywhere as long as the electrical requirements are met- i.e. 240V and hardwiring. Mind you, no venting is required but pipe fittings of 3/4″ NPT is needed for water connection.

An installation manual is provided with detailed step-by-step instructions with helpful schematic diagrams that are easy to understand. Even if you are a newbie, you should be able to do a good job as long as you properly follow each one of the few steps laid out, provided you are handy and have the electrical outlets required.

Considering the electrical requirements involved, we recommend hiring a professional to do the installation for you. This will ensure you don’t end up with a messy installation that could endanger your home or property.

Efficiency

The Tempra plus features an advanced microprocessor technology that allows you to conveniently monitor and control temperature. It also has a self-modulating feature that helps to maintain a steady temperature and prevent fluctuation, such as the advanced flow control module.

You can adjust the water temperature to your desired choice. However, you should be careful when doing this because the water can become extremely hot. Temperature of hot water usually ranges between 86F and 140F depending on your preferred choice and need.

While other models in the Tempra plus series have lower water flow rates below 3 GPM, the 36 plus model has a maximum and minimum water flow rate of 4 GPM and 0.77GPM respectively, which is pretty cool considering its small compact size. It is also interesting to note that this unit costs less to install and doesn’t require venting.

Among the models in the tempra plus series, the 36 plus model has the highest rated thermal efficiency (almost close to 100%). And as expected, since it doesn’t use storage tanks, energy loss is greatly minimized and as a result you get to save on your bills (up to 20%).

Also, this unit is a multipurpose heater, which means it is designed for providing water everywhere in your house; whether, it’s your bathroom or powder room, or even your patio sink.

Space Saving

The usual conception about water heaters is that they use up space, especially traditional hot water tank heaters. However, this is not the case with the Tempra 36 plus tankless heater. This unit features a compact and sleek design that requires less space for installation. The use of a sturdy steel coating makes it suitable for use in both residential and commercial buildings. You can install it anywhere- on the wall, under the sink, inside the cabinet, or on the floor- without any bother as it doesn’t “stick out” too much like most similar brands. In case you decide to take it outside, make sure it is well protected from the elements.

Like we indicated earlier, you should consider hiring someone to hook up the system for you if you are not capable of resolving the electrical supplies that will make the heater to function properly. Or else you can go ahead and become a pro!
