The traditional method of heating water is to have a large tank to store water, and heated for you until you need water. When you turn on the tap, water will start to move through the pipeline until it reaches the position you want, whether it is the kitchen sink, shower, washing machine.
Even if you do not need hot water in your tank heater will continue to heat your water - just in case you need it. At night, the water will remain high temperatures. When you go out to work, the water will remain high temperatures.
This means that when you pay the electricity bill, the money will be lost. Whether it is electricity, natural gas or propane, even if you do not require water, but also need to remain hot state.
In order to increase the damage, the heat will penetrate your tank, waiting for you. Wallet and more money!
On-demand electric water heater or tankless water heaters provide hot water when you need it.
There are around your taps a small unit, roughly equivalent to the size of a briefcase, it begins to heat the water you want. No tanks sitting by. When you open the faucet, water is warming up.
Small means includes a heating element - whether natural gas, propane or electricity - you will immediately heated water.
Think of it as a small "instant hot water" machine, just as if you had used the same coffee or tea!
So, what are the benefits of on-demand electric heater?
There are several advantages, but most people prefer the two benefits is to reduce the size of the hot water unit and save energy.
The traditional hot water tank takes up a lot of space, it may take 2-3 feet square, it may take 4-5 feet tall.
In contrast, the maximum on-demand water heater is mounted on a wall, typically about 2 feet high, 18 inches wide, about 4 inches from the wall extends. Some smaller!
This is why on-demand electric water heaters so popular in Europe, one of the reasons.
Keep in mind that in many cases, the construction of Europe for hundreds of years. Space is very valuable. Difficult to find space for the traditional tank heater - In addition, this type of equipment can be installed anywhere in the vicinity of the hot water needed, for example, under the counter, next to the bathtub, washing machine nearby and so on.
On-demand electric water heater can be placed in the vicinity of each of the hot water tap small units, you can purchase "whole house" of the unit, to provide hot water for the entire family. It only depends on your choices and needs.
Another major benefit is simply that demand the power supply unit can save money.
With the increase of about energy costs, paying only the required energy makes sense. Water heating costs can be reduced up to 50% - Further, when water in the reservoir tank bleeding, heat is not wasted. No tank!
This is the demand of the electric heater so popular in Europe, the second reason. Where high energy costs. It makes sense to use energy wisely.
And you'll never run out of hot water!
Gasoline and electric models
Yes, both gas water heaters, electric water heaters also.
Both are energy-efficient and good for the environment.
Facts have proved inefficient than the electric model gas model. Typically, peak efficiency tankless gas heater point of use from about 80% to 85%, and the peak efficiency of 98%, compared with the electrical model.
Operating costs of natural gas model does slightly better than the running costs of electric models, compared with the demand electric water heater, can save about 10% to 15%.
However, the adjustment of gasoline prices tend to adjust more than the magnitude of the price of electricity, which means that the numbers could change quickly, even worse.
The initial cost of gasoline may be higher than the electric version of its electric model price is about $ 400 to $ 700, while the initial cost of gasoline may be $ 1,000 or more. Installing a gas model is also cost more than the electrical installation.
In my research, I found some shortcomings, or that something might be considered by some drawbacks.
First of all, no tank water heaters, hot water may not be able to handle two simultaneous requests. In other words, if you take a shower and your wife started the dishwasher, you may not demand electric heaters provide hot water at the same time for both sides.
Of course, perhaps you take a bath and then washing dishes is not difficult to do?
The second thing to consider is that, when you need hot water, this time will consume a lot of energy. This can lead to so-called "demand charges," according to your electric company, which can be expensive. You will need to check.
Finally, you need to make sure your home electrical wiring that can withstand high power consumption. If your home is older, and the old line, you need to install the wire, and then install the water heater.
