Getting a tankless water heater is no novelty, since the principle of its work has been known for several decades back. When it was first made, it did not represent a revolutionary invention, but this device certainly got a bright future.
As time passed, tankless water heaters were upgraded in line with energy efficiency standards, which in recent years became an imperative for all manufacturers of electrical appliances. Since this term is often used today, learn more about it on this page.
Higher Initial Costs – Lower Long-Term Expenses
Let us get this straight – if you opt for tankless water heater, the installation is not cheap. If you want a high-quality device from which you can get the maximum, it will cost you several thousand dollars. The price mostly depends on the model you choose, either electric or gas-powered.
And before you made this choice, you have to take a look at a number of factors, such as the proximity of the power source, its availability, the quality of the current installations, the ability to set new ones if necessary, etc. These all affect the final expense of installing tankless water heater.
But don’t let all this discourage you in your intent to replace an old heater with huge storage space with a newer model. There are many reasons why your choice should be one of the tankless water heaters. If you follow the instructions about its installation, use, and maintenance, you could make significant savings in the long run.
Rational Water Consumption
Water is an essential natural resource and, unfortunately, we often waste it or no good reason. From the point of view of individual consumers, savings are negligible. But if everyone could use it rationally, the savings made at the global level would be significant.
Water heaters without storage warm up the water at the same time as it passes through the pipe to the heating unit (gas or electricity). So, there is no space where excessive water is stored and then heated. It sometimes takes hours. On the other side, water heaters without tanks provide constant supply of hot water, without waiting for the massive storage to fill and reach the desired temperature.
There is one drawback in all this. Unlike models with tanks, which are large consumers but also large suppliers, on-demand water heaters have considerably less water flow. The estimated average is around 10 liters of hot water per minute.
This is usually not enough for simultaneous work of two appliances, for example, a washing machine and a shower, even if you use the best electric tankless water heater. Even with the powerful gas models, which supposed to be more efficient, this is sometimes not possible. The solution is to install two or more heating units, especially in places with higher hot water consumption.
You wonder what the saving is. Depending on how much hot water your household spends, the average savings on the monthly level is almost one fifth to one-third of the total mount, for minor users. Besides, heat losses that occur when you re-heat the water in storage space are also reduced. This automatically means a more rational use of the power source, electricity or gas.
No Need for Extra Space
In general terms, new models of tankless water heaters are designed quite attractive. They are usually made in simple lines and cubed forms, in dimensions that can easily fit on any wall, into any room you want.
Water heaters with a tank are huge, massive and heavy. Without special reinforcement, you can’t safely place them on the wall. Because of their size and installation difficulties, they usually need a separate room. With a tankless model, this problem is overcome. No matter which one you choose, gas or electric water heaters, there is not much difference in dimensions – about the size of an average suitcase.
The size of the tankless boiler is determined on the basis of the water flow. You need to know how many appliances in your household require hot water, which temperature it should be, and how much liters per minute tankless water heater can provide.
How to Determine the Size of Tankless Water Heater
Every good plumber can do this estimate for you. They consider all hot water users, but also factors like the climate where you live, the insulation of the building, the distance of the water heaters from appliances, and so on. So they get a calculation of the required temperature increase that the tankless water heater should produce. In warmer areas, the rise in temperature won’t be too high because the entry temperature of the water is warmer than in cold areas. It takes less energy to heat the water.
Less Impact on Environment
Tankless water heaters fit perfectly into the idea of eco-friendly life. Energy and water savings are becoming higher during the period of use. Bearing in mind that the average lifespan of these devices is between 15 and 20 years old, imagine just how many benefits you have done for your environment. The consumption of fossil fuels has been reduced, which also decreases emissions of harmful gases.
Another thing is a less bulky waste. Water heaters with a large storage space have a significantly shorter lifespan than tankless models. Because of the calcification that occurs when the water is collecting in the tank, the pipes and walls are decaying quickly. After 4 or 5 years, you have to consider replacing the water heater. Two decades of use of on-demand models guarantee less junk and environmental pollution.
You can’t do much savings on the size of a tankless water heater. Sure, you can save some money if you decide on a smaller water heater than you need, but ask yourself is it really worth it? It’s better to have a reliable, powerful device that will save you from stress and provide you with hot water in a second, even if a couple of dollars don’t stay in your wallet.
