Many people nowadays initially presume that tankless water heaters are much better than traditional tank-type ones. Tankless water heaters simply work by heating up the water instantly by the time the hot water tap is turned on. One main difference between a tankless water heater and a tank-type water heater is that there are no standby losses in tankless units; there is no hot water idly sitting around inside a tank, which then continuously loses its heat to the air surrounding it, and then it has to be re-heated once it is needed. This actually makes it sound good to have a tankless water heater unit for your home, right? However, the truth is, the standby losses are not that very significant. The hot water oftentimes gets used up before it loses it heat to the air surrounding it.
Below are some facts that you will find out when you have a tankless water heater unit:
- The standby losses are not very significant. Almost all of the hot water present in the tank is normally used up before it loses its heat to the air surrounding it.
- If your family is a big one, then your savings will be much less. This is due to the fact that it is more likely that a family member might use the hot water in the tank before its heat will be lost to the air surrounding it.
- Installing a water heater timer is a wise option. Whatever the amount of standby losses you incur with your old tank-type water heater, you can actually avoid some of these losses when you install a water heater timer.
- The minimum flow requirement equates to wasted water. Tankless water heater units do not immediately start heating up unless there is a specific minimum water flow. To solution is to replace the low-flow shower head with a higher-flow shower head. When this is the case, water is absolutely wasted, and therefore you are not saving any energy at all due to the fact that there is more water present to heat up.
- The average savings you will get with a tankless water heater unit would only be about $6 to $7 per month. You are considered to be lucky enough if you are able to save up to $9 per month. However, sadly, most of the times there would be no savings incurred at all. Moreover, that savings is even before purchase and installation prices as well as maintenance and repair costs which would typically cost you more if you have a tankless water heater.
- The installation fee of a tankless water heater unit ranges from $600 up to $1600 more than that of a standard tank-type water heater unit.
- The $6 to $7 savings are only achieved if you have a 50-gallon tank in your area. If your water tank is a lot smaller, then of course your savings will be smaller as well.
- If you have an endless supply of hot water, then you will be possibly tempted to take longer showers. Most people say that they do not take long showers even if there is plenty of hot water for them, but there are a few that really take their time actually. If you are one of the few, then this means you do not incur any savings when you do take longer hot showers.
- It takes about 2 minutes max for hot water to reach to the faucet. Even if your pipes are well-insulated, this can still happen if you have a tankless water heater unit.
- Electric-type tankless water heater units lets you save even less money. An electric tankless water heater unit might only help you save just about $3.00 per month unlike an electric tank-type water heater unit.
- The warranties are typically much shorter. Tankless water heater units are thought to last much longer than tank-type water heaters; however, it might surprise you that in stores the tankless water heater units have 1 to 5 years of labor/parts warranties, whereas the tank-type water heater units have 2 to 6 years of labor/parts warranties.
- Tankless water heaters are usually not compatible with geothermal and solar types of energy. If you are planning to use solar or geothermal energy for heating up your water at home, for sure you will not be able to do that with a tankless water heater. You will need to have a tank for that.
- If you have hard water in your area, then it reduces the efficiency of the water heater. Hard water and other sediments in it can quickly cause some buildup in tankless water heater units, which reduces their efficiency significantly, thus making them have a tendency to break down much faster. Standard tank-type water heater units are actually more tolerant and robust when it comes to hard water issues. You may want to soften your water, but then again, if you do, then your efforts of saving with your tankless water heater unit had been all for naught.
Below are some well-known advantages of tankless water heaters over tank-type ones:
- There will always be hot water available for everyone. If you have a large family or you have some guests staying over, you will never run out of hot water when you have a tankless water heater.
- There will be no leaks. It is very rare to have leaks with a tankless water heater, whereas it is very common to have leaks with tank-type ones. When your tank-type water heater is leaking, this could potentially damage your home and it is also quite costly to have it fixed up.
- They are practical space savers. Since tankless water heaters tend to be small, they take up only very little space/room inside your home. You can even easily and quickly mount them right on your wall!
- Tankless water heaters are estimated to typically last for about 15 to 20 years, unlike tank-type water heaters which lasts for maybe 10 years or less.
