Tank vs Tankless: Explaining the Tankless Hot Water Heater

When your old water heater is nearing its end, your plumber may recommend going with a tankless water heater. While each provides hot water when you need it, today, large water heater tanks are being replaced with tankless models. The following will describe the differences between a tank and a tankless hot water heater, and why many are considering making the switch.

Hot Water on Demand

Of course, the most obvious difference is that a tankless hot water heater does not require a container to hold hot water in. Instead of using a tank, like older water heaters do, a tankless model uses special heaters to bring water up to temperature when a consumer calls for it. This process results in the production of hot water only when requested, while a water heater with a tank will keep water at heated temperature continuously.

Energy Efficiency

A tankless water heater uses less energy than one with a tank. How water kept in a tank constantly uses energy to maintain the water at an elevated temperature. Even if the water is not being used, the water stays hot. In contrast, with a tankless version, the water does not heat up until someone in the household needs it. While the tankless uses bursts of energy while heating, it uses little to no energy when there is no demand for it.

In addition, a tank water heater generally uses propane, natural gas, or electricity for power. Natural gas and electricity are the options usually available with a tankless model. The natural gas option is the most efficient in both the tank and tankless models.


Hot water output is another difference between tank and tankless water heaters. The amount of hot water you receive from of a water heater with a tank depends on the size of the reservoir. If the demand goes beyond the amount of hot water in the tank, the consumer may get a blast of cold water. With a tankless heater, the amount of hot water available is almost limitless because there is no need for a finite reserve.


Installation requirements for each type of water heater is a bit different. For a tank version, you will need a designated amount of square footage in which the tank sits. The plumber will need a source of power and water lines to the area as well. For a tankless water heater, the plumber will need wall space on which to mount the tank. The unit usually sits a few inches out from the wall surface. Again, a source of power and water lines will need to be near.


Maintenance requirements are different for tank and tankless water heaters. Every year manufacturers recommend that home owners flush a tank heater to remove sediment. These models also have sacrificial rods that need replaced every few years. For tankless models, filters that catch sediment need changed and routine flushing of the heat exchanger will do the job.
When you need to think about installing a new or replacing an old water heater, it is a good time to consider changing from a tank to a tankless water heater. Each has its advantages and disadvantages and the choice depends on the home owner’s preferences and regulations in the area. Some new subdivisions are requiring tankless water heaters. Most homeowners like the tankless option due to the energy efficiency and reduced danger of a water leak.

Water Heater Replacement and Other Tips for Saving on Heating Costs

When winter rolls around, you’ll find that it is essential to make sure that you know how you are going to keep heating costs down. With the price of fuel as high as it has been, it can be tremendously difficult to keep your home as comfortable as you would like it to be. The truth of the matter, however, is that it is completely possible to make sure that you stay warm without breaking the bank. Check out these tips that will keep you warm throughout the winter. Sometimes the most effective form of saving on heating costs is to finally look into Water Heater Replacement, and upgrade to a more energy efficient water heater.

Water Heater Replacement

Water heating can often be 18% of a person’s total heating bill during the winter. With the promise of better energy efficiency and lower heating costs, many homeowners look toward Water Heater Replacement as a solid investment. Newer and more efficient water heaters are certainly the way of the future, and there is simply no reason for anyone to be tethered to their old water heater any longer. If you are looking for an Energy Star water heater, it’s important to keep in mind the differing ‘green saving’ tags associated with some of the models, including high efficiency gas non-condensing, gas condensing, electric heat pump, gas tankless, and solar. Regardless of which new water heater you choose, any upgrade will undoubtedly serve you and your home better this winter.

Install a Programmable Thermostat

If you are someone who is invested in making sure that your home is warm when you walk in the door, consider installing a programmable thermostat. For example, you can set the heater to kick on just half an hour before you walk in the door. This means that you will not be heating an empty house for the entire day that you are gone, and that you will also not be coming home to something that feels like a chilly cave!

Plastic Heat Seal

Heat escapes the house through the windows, and this is especially true if you are living in an older home. To reduce the amount of heat that escapes through the window, seal the window entirely with a plastic heat seal. Plastic heats seals look like large sheets of plastic wrap. They are pressed taut over the window, and when you do it right, it is nearly invisible. This provides you with one more layer of air between the outdoors and your home, and it can drive your heating bills down significantly. Alternatively, you can install energy efficient windows. While they may be a more expensive option up front, they can help with energy savings over time.

Close the Doors

When you want to keep your home warm in the winter, remember that the more you compartmentalize your home, the better. If you keep the doors closed, you will seal the heat into the individual rooms. This will leave the home feeling much cozier in general, and you will also find that it makes a huge difference when you are thinking about how you can keep the heat trapped in your home.

Insulate Doors and Install Draft Blockers

If you have doors leading up to the attic or down to the basement, you need to find a way to make sure that they do not let out too much heat. Because both basements and attics are frequently unfinished, you’ll find that they leach heat at a rather alarming rate. There are many ways to insulate these doors; some people attach Styrofoam or pieces of insulation to the back of the door itself.

Heat also escapes the house through the bottom of the door, and if you have a gap between the door and the floor, you’ll want to take care of it with draft blockers.

If you want to make sure that you have got everything taken care of for the winter, you’ll find that it will be much less costly for you. This can help you save some money just in time for the Holidays!

Signs You Need to Replace Your Gas Hot Water Heater

It is always important to be prepared if you think your gas hot water heater may be in peril. If your water heater happens to break, you might be without hot water for a couple of days. However, if you are prepared for this unexpected event, it will be less of an inconvenience to have a new installed. In order to prepare, it is important to properly identify the warning signs of a water heater that is need of replacing.

Check the Temperature

Make sure to keep an eye on the water temperature and be sure the water is not coming out too hot or too cold. You can check this by simply making adjustments on the water heater’s thermostat. The standard setting for water temperature in the average household should be between 120 and 140 degrees Fahrenheit. If you find that the water temperature is irreversible set in extreme temperatures, it may be time to consider replacing your gas hot water heater.

A Noisy Water Heater

Another sign that your water heater is not working properly is by the noise it emits. A normal water heater will usually run smoothly and quietly. However, a water heater that would need fixing or replacing will tend to make a lot of noise. Sometimes, a noisy water heater can be easily fixed with a cleaning or by flushing out the system. If you try this and are still hearing a lot of noise, then it may be time to replace your water heater.
Consider the Age of the Water Heater

The age of the water heater is another aspect you want to take into consideration. Most water heaters will come with a warranty that covers three to six years of malfunctions. However, the majority of water heaters can last up to ten years with proper upkeep. You can also look at your water heater’s overall condition. A water heater that looks to be deteriorating or malfunctioning regular should be replaced.

Water Quality and Usage

Although a water heater may be only three or four years old, it can still need replacing in the end. This issue is due to water usage. If your home is filled with multiple people, then chances are that your water heater is used regularly. Large water consumption will age the water heater much quicker versus a water heater that is used on occasion. Another way that you can check whether or not you need a new water heater is to check the quality of your water. Hard water will tend to age your water heater much faster than soft water.

Leaking Water is a Big Clue

Leaking water is probably the biggest clues you can receive as to when it is appropriate to replace your water heater. If water suddenly begins to leak from the sides or the bottom of your water heater, then you need to call a professional plumber immediately. This is a sure sign that your water heater is already out of order.

Remember to keep these issues in mind when you inspect your water heater or are considering having it replaced.
