tank vs tankless water heater

Tankless Water Heaters

Tankless water heaters are a relatively recent innovation but they have quickly gained popularity due to their ability to provide a consistent supply of hot water. A tankless water heater heats the water as it flows through the device. Unlike a tank water heater they do not store any water except for the water which is inside the heat exchanger coil.

Advantages of Tankless Heaters

Longer Life – Tankless heaters typically have a usable life of 15 to 20 years. This compares favorably to tank heaters which usually last 8 to 10 years.

Avoid Cold Showers – If you share your home with other family members then cold showers are probably a frequent occurrence. With a tankless heater the water is heated as you need it. This means that cold showers will become a thing of the past no matter how many people use the shower before you.

Take Up Less Space – Tankless heaters can be placed almost anywhere in the house and take up less space than tank heaters. You can hang a tankless heater on the wall both inside or outside the house. This also means that you can use space which is currently being used for your tank heater as a cupboard or wardrobe.

Provides Cleaner Water – Tank heaters will often build up rust inside the tank. Tankless heaters do not suffer from this problem and so provide cleaner drinking and bathing water. Go online to get the top quality tankless water heater for yourself.

Disadvantages of Tankless Heaters

Limited Water Flow Rates – When selecting your heater it is important to match the demands of the water needed with the unit size. Smaller tankless heaters may limit your water flow rate.

Higher Upfront Costs – Tankless water heaters are less expensive on an ongoing basis but they also typically have a higher upfront cost.

Pilot Light May Waste Energy – If the pilot light in the tankless heater runs constantly the tankless heater may waste more energy than with a tank heater. However many tankless heaters features an intermittent ignition system which helps to avoid this problem.

Electrical Capacity Required – Tankless heaters will sometimes require added electrical or gas capacity in order to support the unit. If this is case their will be an additional cost and so this needs to be weighed against the ongoing cost savings.

Tank Water Heaters

Tank water heaters, also known as storage water heaters, have been traditionally the most common type for residential and commercial use. A tank heater uses a cylindrical vessel or container to store water where it is kept hot for use. Most water heaters in the United States and Europe are heated use natural gas due to its lower cost.

Advantages of Tank Heaters

Lower Initial Costs – Tank heaters have a lower initial cost than tankless heaters and are usually already installed in the household. Unless there is a compelling reason to change the tank heater it may be better to simply keep it in place.

Newer Units Are More Efficient – If you have an old tank heater then the energy savings compared to a tankless heater will be significant. However many newer tank heaters are much more energy efficient and so the difference may not be substantial enough to justify a tankless heater.

Large Tank Units Are Usually Adequate – If you have a large tank heater installed in your home then you should find that you don’t run short of hot water even with a demanding household.

Disadvantages of Tank Heaters

Recovery Time Can Be Extensive – The recovery time to reheat the water in the tank can be extensive. The tank may take upward of half an hour to reheat. This often means missing out on having a warm shower in the morning.

Maintenance Required – In order for a tank water heater to reach its maximum life span maintenance will typically be required. This is difficult and can be expensive as it will usually require a contractor.

Take Up A Lot Of Space – Unlike a tankless heater which can be hung almost anywhere a tank heater takes up a lot of space. The bigger the hot water supply your household requires the more space you will need to devote to your heater. This typically means giving up storage space that could be used for other purposes.

Hybrid Water Heaters

A hybrid water heater incorporates elements of both tank and tankless water heaters. Like a tank water heater it is able to maintain consistent water pressure and supply over multiple applications such as more than one shower. But like a tankless water heater it can also supply continuous hot water on demand.

Advantages of Hybrid Water Heaters

Extremely Energy Efficient – General Electric estimates that the savings that the average family will achieve by using its hybrid water heater are an average of $250 a year.

Fewer Greenhouse Gas Emissions – Hybrid water burners are in general better for the environment than traditional heaters. They produce little in the way of greenhouse gas emissions and are among the cleanest burning of all appliances in the household.

Less Space – While a hybrid water burner does have a tank it is considerably smaller than with a traditional tank heater. Typically a hybrid will take up about half the space of a tank water heater.

Disadvantages of Hybrid Water Heaters

Comparatively Expensive – Compared to tank heaters and even tankless water heaters, the hybrid water heater is very expensive. Due to their energy efficiency over the long term they may work out to be less expensive but in order to enjoy this benefit you must be planning to live in your current home for the foreseeable future.

Solar Water Heaters

Solar water heaters are becoming increasingly common due to their low running cost and the fact they are environmentally friendly. Solar water collectors are typically installed on the roofs or walls of the residence. Solar water heaters can be used in conjunction with a traditional storage water tank or one that is specifically designed for that purpose.

Advantages of Solar Water Heaters

Significant Energy Savings – As we saw in the introduction, household water heating makes up to 15% of energy usage. Using a solar water heater removes this cost which can amount to considerable long term savings.

Rebates And Tax Breaks – There are a number of rebates and tax breaks available for installing solar water heaters. For example the California Solar Initiative (CSI) offers up to $2,719 for installing a solar water heating system in a single family home.

Disadvantages of Solar Water Heaters

High Initial Cost – Compared to a traditional water heater the initial cost of installing a solar water heater can be high. This is particularly true if you are installing panels in an area where there are limited amounts of natural light. In order to capture sufficient light more panels will need to be installed increasing the costs.

How Do Tankless Systems Save You Money

Many homes in the United States are now using tankless water heaters – the numbers have in fact risen drastically in the past few years. As Americans have become increasingly aware of the many benefits offered by tankless systems, these high-power appliances have become a more common option for water heating.

The growing popularity of tankless systems is partially due to the excellent marketing strategies utilized by the manufacturers. The leading brands have cleverly promoted their product by showcasing the advantages of tankless water heaters over storage-type or tank-type models.

In addition, the internet has helped to make important data readily available to customers. Today’s intelligent consumers go online to do their own research on certain merchandise, collate the facts and compare products. Based on the information they have gathered, they can then make more informed decisions about which products to buy.

Tankless Water Heating Systems: A More Practical Choice For Your Household

Naturally, consumers tend to opt for merchandise that they perceive as the better choice – something that not only provides them with additional benefits, but also more value for their money. Furthermore, with the increasing awareness of ecological issues, many American households prefer environment-friendly solutions. People have apparently found tankless systems to be a wiser option, as these ultimately cut down on water heating bills and are safer for the environment.

The leading brands in tankless water heaters are continually developing their technology in able to produce better, more advanced systems. Manufacturers who seek to gain the advantage over their competitors thus endeavor to constantly improve on their product, introducing further enhancements that can attract more customers. As a result of this healthy competition, the latest models available in the market today are much more consumer-friendly and energy-efficient.

how to save money on heating

Currently the most sought-after water heating solution for American residences, tankless systems – also called “on-demand” or “instantaneous” heating – have the ability to heat water instantly. Even without having to store water internally, these highly efficient devices can provide an abundant, non-stop flow of hot water whenever needed.

Tankless heating systems are available in various sizes and capability, making them suitable for different households with distinct needs. Certain models, for instance, may be appropriate for use in a home with only one bathroom; other more powerful ones can accommodate residences that have a shower in each of the four bedrooms. With all these variations, there is an ideal on-demand water heater for every kind of home.

Even with the diversity, all tankless models share one significant factor: they all substantially reduce the monthly water heating bills. An instantaneous heating system uses up much less energy compared to a tank-type or storage water heater. In the latter, water is continuously heated 24 hours a day, whether or not the hot water is being used anywhere in the household. For instance, while the residents are doing other things that don’t require heated water – such as, when they watch television, take a leisurely nap, or even when they leave the house to go jogging – the tank-type heater keeps consuming energy. In effect, a whole lot of unnecessary expenses are accumulated just to maintain the hot water supply.

With the tankless system on the other hand, the heating occurs only when hot water is needed. The temperature of the water increases instantly, right when a tap or shower is turned on. This process requires no constant heating, and absolutely no unnecessary energy consumption. In turn, this significantly decreases the water heating bills, thus saving more money.


As you buy a water heater, you’ll have to make a number of smaller decisions next to the big ones (like gas or electric, tank or tankless, and size). Just because they’re smaller, doesn’t mean these considerations aren’t significant. If need be, take them one at a time lest you get so overwhelmed you just buy the first heater that you see. And now,  How to Choose Water Heater Options?


How to Choose Water Heater Options

1. How Long Will You Be In Your Home?

The length of time you’re intending to live in your home will have a big effect on the water heater options that matter to you. Hybrid and solar water heaters don’t make sense if you’re going to move after a few years, as their start up costs are too high. On the other hand, if you’re going to live in one place for more than a decade, these kinds of options can save you huge amounts of money in energy saved. Those savings may well justify the up front investment. Top rated Bosch tankless water heaters can save you lot of money.

2. How Much Do You Care About The Environment?

The more you’re concerned with the environment, the more efficient the model should be that you end up buying. The “greenest” water heaters are hybrid and solar powered types.

3. What Kind Of Heater Is Your Home Designed To Use?

If your house doesn’t have a basement gas line, you may need extensive renovations in order to get the place ready for the heater. If the place you’re moving in to is already built or you’ve already approved a floor plan, be sure the house can accommodate the kind of heater you want. Obviously, this will also be a factor in considering solar water heaters. Your home’s layout and the already existing water heater (if there is one) might make your water heater choice very easy by virtue of your limited options.

4. How Much Space Are You Willing To Allocate To A Water Heater? Where Do You Want To Put It?

Tucking a water heater into a kitchen closet means you’ll need to go electric. For a water heater that takes up next to no space, you’ll want a tankless model.

5. Pay Attention To The Warranty

Compare water heater warranties and get one that cover the heater’s major working parts for a good length of time. If you have a warranty that mandates frequent maintenance, be ready to drain your tank heater and fill it at least annually, and possibly apply other sediment and rust reducing measures.

6. What About Buying A Water Heater Stand?

Water heater stands lift a gas water heater off the ground, reducing the fire hazard. They can also help ensure the heater stays dry if your basement floods. – Brass or plastic water heater valve? Water heater valves may malfunction or break off. Paying a little more for a brass valve may help prevent this. Knowing your water heater in and out will ensure you can service it when needed with spare parts.

7. Consider A Water Heater Pan.

A water heater pan may be very handy if an overflow or leak appears from excess tank pressure. These pans have attachments so you can get rid of the excess water with a drain hose, and may come with an alarm that alerts you to an overflow.

8. Additional Water Heater Accessories You Might Consider:

Pressure regulators on your water heater will keep the internal pressure from exceeding the limit of your tank as water flows in. A regulator may protect your pipes from bursting due to overpressure or leaking. You can add a timer to a water heater to ensure it only heats during the hours when you need it, saving energy costs.

Blankets are available for many water heaters and help further insulate the tank, reducing the leakage of energy from the freshly heated water inside. These can be a great investment for water heaters located in unheated parts of the house like garages.

What is an Electric Tankless Water Heater?

Tankless water heaters are also known as on-demand water heaters. They’re called such because they provide hot water when and where you need it, without having to store any water. They provide instant water when you turn them on, and it shuts off when you turn them off. They also deliver fast.

Therefore, there is no wasted energy and no wasted water. The power source that generates such heaters is your electric supply. It works simply by instantly heating water as it flows through the device.

There are two types of electric tankless water heaters: point of use (POU) and whole house. You can install a point of use unit in your bathroom or under your sink. But if you want your water heater to be centrallized, you can also choose the whole house units where it can provide more heating ability to your entire house or establishment.

Electric Tankless Water Heaters are a great way to save on energy, space and time. Most units are so compact that you can hide them easily on walls and cabinets. They also require less maintenance than other types of water heaters. Their life expectancy is also longer, since they don’t corrode as much, lasting up to 20 years compared to 13-15 years of a tank water heater. They also eliminate standby losses, which is energy wasted by warm water that just sits around unused in the tank. Installation is also relatively cheaper compared to tank and gas powered heaters. They’re economical, easy to install and maintain, saves you time and energy, and ultimately helps you conserve water.
