What are Tankless Water Heaters?

Typical water heater systems have been in use in homes for decades now and therefore are the most known globally. These consist of a large water tank that stores water and an electric coil that heats the water. They also have thermostats that retain the temperature of water at your preferred level. These water heaters use several energy sources including electricity, propane, solar energy, and natural gas. Tankless water heaters, also known as ‘on-demand’ water heaters use electric coils to heat water on demand instead of storing it in a tank.

Tankless units measure around the size of a suitcase, but smaller models are also available in the market. Depending on the type, they use electricity or gas and heat cold water as it passes the element, which it delivers through a tap or a shower faucet for people to use.

With a tankless water heater at home, you can heat cold water on demand and access it via a tank or shower faucet for as long as you want. Thus, for a few dollars, you will never worry about your shower faucet running out of hot water as is the case with tanked systems. If you are considering upgrading your bathroom with one, you should have a better idea of how these water heaters work to use them well. Overall, whole-house units split water to separate lines that serve different areas of the home, lowering water flow as a result. Most models can deliver an average of 2 to 5 gallons of water per minute.

Advantages | Electric Tankless Water Heater

The best tankless water heaters trump tanked models in terms of their capacity or water supply. They are also super-efficient. Unlike tanked systems that store water in a tank and heat it consistently to maintain a specified temperature, the best tankless systems provide hot water on demand – they only heat water when needed – lowering running costs. Therefore, to lower heating costs by 14-18%, consider replacing your old tanked water heater with an efficient tankless water heater today. It also reduces water flow per minute and therefore wastage of water.

Tankless System vs Traditional Water Heater

In addition to their efficacy and eco-friendly design, you will love the space-saving design of some of the best tankless systems. Most models are smaller than electric units and therefore blend into and work in small spaces in homes, including closets and the under cabinets.

Moreover, because they do not need a large storage tank to work, the risk of flooding your home because of a ruptured tank is relatively low. Moreover, you will never worry about a leaking tank, which is one of the top five causes of floor and beam damage in wooden homes. Rust and growth of mildew are also low with a tankless water heater at home.

Even though simple, expect years of excellent service from some of the best tankless water heaters in the market. If you can find a well-engineered model made from high-quality materials, the product will serve you for almost twice as long as a traditional tanked heater would. With proper maintenance, the system could serve you for 15-20 years, which is good. Normal tanked systems last for approximately 10 years.

Disadvantages of Tankless Water Heaters

Even though beneficial, the best tankless water heaters have their unique drawbacks. For instance, the equipment costs slightly more money upfront compared to the best-tanked water heaters for one reason – they have a complex design that costs significantly more money to manufacture. They are also harder to set up than traditional tanks, especially if you are retrofitting one to an old tanked system. While doing this, expect additional expenses for the upgrades/add-ons.

Finally, because tankless water heater heat water on demand, expect a short lag time before hot water starts flowing from your tap or shower faucet. This is not the case with a tanked water heater that keeps water at a certain temperature all the time, albeit at a higher electrical cost. You get hot water almost instantly depending on how far your tank is from your tap or faucet. Tankless units deliver water instantly as well but you wait for around 10-15 seconds for how water to start flowing.

The Facts About Whole House Electric Tankless Water Heaters

When it comes to access to and usage of hot water at home, different homes have different needs. Factors such as the size of your home can influence the type of tankless water heater that you will need. If you use a low of hot water in the morning, you will need a high throughput tankless water heater and vice versa. The temperature of groundwater also determines the type of system you will need. Do not overlook that.

The heating capacity of a tankless water heater is dependent on the temperature rise (the difference between the temperature of a thermostat and groundwater) and the flow rate of your system. If groundwater is cool, the system will use more energy to heat water to your desired temperature at your desired flow rate. Keep these attributes in mind.

Whenever you are shopping for a whole house tankless water heater, you will have to choose its capacity, often presented in gallons per minute’ or GPM, which refers to the flow rate of water from the source. Factoring the GPM (gallon per minute) rate in decision making is important whenever you are shopping for water heaters as it depicts how long the system will take to fill a jacuzzi or bathtub with hot water.

Different appliances that you use at home have different GPM on the label or tag. If you cannot locate the tag or label on a product, here is a simple method for locating the measurement. Standard bathroom sinks have an average flow rate of around 0.5 to 1.5 gallons per minute.

Some tankless systems do not provide what their manufacturers promise. With the release of tankless water heater units several years ago, people experienced multiple issues including inconsistent water temperature, difficult installation, and frustrating maintenance.

In this crowded niche, two major brands stand out – the Stiebel Eltron and EcoSmart tankless water heater. Reputable all over the world, these dependable brands have alleviated all the problems or hiccups that people encountered with the earlier versions of heaters.

Stiebel Eltron Tempra Plus Whole House Tankless Water Heaters

Stiebel Eltron has been in the market for many years now. It has decades of invaluable experience in this manufacturing technologically advanced products, including the best whole house tankless water heaters. One of the drawbacks of its tankless water heaters is that they cannot provide hot water consistently when running at full pressure.

The company has been around for decades. You are safe.
Stiebel Eltron Tempra Plus Whole House Tankless Water Heaters

For instance, if someone was washing dishes while you are taking a bath, the boost in demand for hot water is too high for some systems to handle. Because the water heater distributes water to multiple sources, the tankless system cannot maintain the ideal temperature throughout. As such, you experience cold spots, which is not fun.

However, standard tanked models are not “immune.” When the demand for hot water exceeds the tank’s capacity, you will have cold water after a few minutes of showering, which is not enjoyable. The major difference with tankless water heaters is that you wait for longer for the tanked system to bring the water back to temperature.

Stiebel Eltron has overcome this major setback with the recent release Tempra PLUS whole house electric tankless water system. The system has an advanced Flow Control that lowers water flow when the demand for hot water is higher than the system can support. As such, whenever the water demand is higher than the system can support, it will supply hot water consistently at the correct temperature. You will only shower for longer as the water pressure will be slightly lower. This feature is available in only the Tempra PLUS line of water heaters only.

As such, when setting up a new system, pay attention to the climate.

All these models have a few innovative features including a power modulation system (full) and digitized temperature controls. They also have a temperature regulator that you can use to set the temperature of water in real-time. Use the dial selector in front of the panel to set a temperature of between 86-140 degrees Fahrenheit. Finally, this wall-mountable water heater features overheat protection for safety.

Choosing the Best Tankless Water Heater

If you have read this article diligently from the start, you now have a good idea of what tankless water heaters are and whether they can satisfy the hot water needs of your home. Now, the ball is in your court. Guided by the information we have offered you thus far, you should decide the route you want to take. Tanked water heaters are cheaper to install, but bulky and costly in the end. Tankless models, on the other hand, are practical when the need for instant/on-demand hot water is high.

Most of the advanced tankless water heaters available in the market have many thoughtful qualities and features that make them effortless to install and work seamlessly in most settings. For the best results, hire a professional to install the product for you. Installing the system by yourself could void its warranty or cause serious damage or injuries.

They take up little space and have high flow systems that satisfy the needs of most people. Also, compared to tanked models, they offer significant space and power savings, making them ideal for use in small, medium size, and large homes. Therefore, if you are considering buying a traditional tanked system, think again. A tankless water heater works the best.
