How to Get More Hot Water From Water Heater

As the temperatures outside start dropping, many people’s thoughts turn to stay warm indoors. One of the most common ways to do this is by using a water heater to produce hot water for bathing, cooking, and laundry. However, many people aren’t aware that they may be able to get more hot water from their water heater by making some simple adjustments. In this article, we’ll discuss how to get more hot water from water heater. Read on to learn more!

A water heater is one of the most popular heaters for homes. However, many people aren’t aware that sometimes there is a limit of hot water produced at one time, and they don’t think of ways to get more hot water from their water heater.

How to Get More Hot Water From Water Heater

A Detailed Guide on How to Get More Hot Water From Water Heater

Step 1: Usage Efficiency Improvements

The first thing you will want to do is find out if any leaking hot-water taps or showers will be wasting water. You can determine this by turning off all the faucets and then running the water into a bucket. How much you use during a particular time will tell you how efficiently your hot-water system runs.

If your hot water usage is inefficient, try installing a new tap aerator or showerhead. Aerators and shower heads with low flow rates will reduce the amount of water used per minute for a similar amount of relaxation from both types of installations mentioned above. For example, old aerators have an average flow rate of 5 liters per minute, while new aerators have an average flow rate of 2 liters per minute.

Step 2: Using Extra Tanks

If your problem is that you have a smaller tank and need more hot water at one time, or if multiple people live in the same household, the best solution would be to install an additional tank. The simplest way to do this would be to put a new 50-gallon electric hot-water heater on the old unit.

Next, it will need an expansion vessel and a foot valve to be installed between two distinct cold water feed lines. This will work as long as both tanks can fit physically and there is enough free space for insulation around them; typically, existing tanks within buildings cannot be replaced with more extensive volume requirements.

Using Extra Tanks to Get More Hot Water

These vessels will contain air that needs an electrical charge to support the hot water. This charge is usually provided by the heating elements within the bottom of the tank, which will create air pockets within it. These air pockets are essential because they give buoyancy to the water to rise to the cold water line.

Since this method does not work with gravity, an auxiliary pump has to be used instead. The pump should always be controlled by a thermal sensor attached to or next to one of its pipes; these sensors will send out an alarm if they sense that there is no hot water running through them.

Step 3: Tapping into Another Hot-Water Heater Will Serve Your Needs

If you need more hot water at one time, but you do not have a place in your home to install a second tank, the most efficient way to solve this would be by creating a “line-to-line” connection. This is done by running PVC piping from your central water heater into another pre-existing heater that can provide more hot water.

The piping will go through some accessible and reachable areas and terminate at the top of the central heating unit. The two units must also have soldered pipe unions and compression fittings with sweat connections on them; these parts are usually available at any hardware shop or plumbing supply store and online.

Step 4: Avoid Overloading Your Water Heater

You have to ensure that you do not overload your current tank, so it does not explode. This will always run the risk of causing harm to nearby occupants and surroundings, so be careful with this method. Also, the tank should never be filled above its “Max Fill” line, or there could be hot water leakage, or it could even explode eventually. This is because they are not equipped with the storage tanks’ safety valves.

Step 5: Insulate Piping to Reduce Heat Loss

You should always insulate hot water supply piping if it is exposed to the elements or if you want to save energy. This can be done by using closed-cell insulation boards made of polyethylene plastic and having a foil face on one side. It’s important not to cover any part of the pipe to let the heat circulate properly without needing additional energy for it.

This will keep water hot even when there are gaps around it that could cause heat loss, such as behind your toilet tank. Insulation boards are also flexible enough because they are designed with an adhesive backing that allows them to stick onto different surfaces. They’re easy to install and measure up at about 1 inch thick, and they come in many different lengths and widths to fit your needs.

Step 6: Wrap Your Water Heater in Bubble Wrap or Fiberglass Batting

If you want a cheap method that will not provide much insulation, it would be best to use bubble wrap or fiberglass batting. These two materials are highly effective at insulating water heaters because the hot water will cause it to expand and contract like a balloon; this produces a thin film that keeps out any cold air and traps all of the heat inside.

The only downside is that these materials aren’t very durable or long-lasting, so they may need replacement every year or two, depending on how often the heater is used. This method should also be avoided if there are pets or children in the home, as they can easily chew and tear up the insulation and pull it off.

Step 7: Cover with Reflective Insulation

It would help if you considered using reflective insulation for a permanent insulator that will protect your heater from cold air infiltration. This is made of aluminum foil on one side and plastic on the other; when applied to hot water supply piping as most methods do, this material reflects heat into the room where it came from.

This way, no heat loss occurs, so no outside energy is needed to re-heat water once it has been used or consumed by occupants in a particular area or structure.

If you follow these steps, how to get more hot water from water heater for your house should not be a problem anymore.

Additional Information

Since so many people use hot-water heaters every day for different tasks, they often forget about the importance of maintaining them well, especially if they’re electric models. In addition, because these appliances are usually used in homes or buildings that contain families or larger groups of people who use them all day long, the demand for hot water increases significantly over time.

Use Hot-water Heaters Every Day

Before you know it, your hot water can run out very quickly during peak times because there is only so much tank capacity to go around, which wastes a lot of money and energy and causes inconvenience.

The best way to deal with this problem is by using this information to upgrade your current system with additional units that will deliver more hot water when other areas need it the most. However, it’s essential to consider all options before anything drastic, like replacing your entire unit, because not every solution will result in the same outcome.

Doing your research will save you time, money, and trouble in the long run by helping you make a more informed decision on what type of upgrade would be best for your specific needs.

Why Is My Hot Water Heater Not Producing Enough Hot Water?

Many of us have trouble getting enough hot water from our water heater. You have a big, modern, efficient-looking tank heater capable of heating two to six gallons per minute, usually on the highest setting. Yet, you still run out of hot water before your morning shower is over! Five common problems contribute to this dilemma.

Top 5 Reasons for Not Enough Hot Water from Your Water Heater

  1. Clogged burner orifices from sediment build-up.
  2. Restricted gas supply due to a clogged vent from soot build-up from the burner, lack of maintenance, or installing too short of a gas supply line.
  3. Old elements with little output and poor regulation.
  4. Thermostats are set incorrectly – either not low enough for a small household or not high enough when heating a larger home with more occupants that require hotter water.
  5. Bad or loose dip tube in the tank that allows cold water at the bottom to mix with hot water at the top, thus reducing hot water available from your heater no matter how big it is!


You can save money by cutting back on your water heater’s energy usage. If you are looking for ways to make it easier, try these tips. Some of the best ones include insulating pipes and ensuring that the tank is set at a low-temperature setting. Learn more about how to get more hot water from water heater with our article!.
