Changing a Hot Water Heating System? Know the Best Time

When to change the Hot water heater in your house?

If your hot water heater is more than 10 years old, it may be time to change it. When shopping for a new water heater, keep these energy-efficient alternatives in mind.


A water heater’s tank should last six to twelve years with better upkeep, however, tankless water heaters can last up to twenty years.


For the most up-to-date deadlines, you should consult your guarantee.

How can you tell when it’s time to replace your water heater? A water heater that is frequently preserved and repaired as needed can last for many years. You‘ve probably been using the very same water heater since you moved into your present property.

All better things will need to arrive at an end, and you will need to change the water heater at some time in the future when it can no longer do its task.


You may at first think about having the water heater repaired, but there are indications to look for that will help you determine whether to change the warm water heater in your house.

Here are 5 indicators it’s time to change your water heater:

None of these signs are a sure hint that it’s time to change the hot water heater. Prior to making a decision, always talk to an experienced plumbing service. If the repair work are still beneficial, the plumbing contractor can advise you.


In a typical property, how long do hot water heater last? Most systems have a life-span of 15 to 20 years. Despite the fact that the present water heater is in good working order, it is normally best to install a new system if it is more than 20 years old.


A drop due to age will take place soon, and it is smart to get ahead of it by buying a new water heater.

The amount of hot water lost

A low amount of hot water is another clear idea that it is time to change your hot water heater. These are indicators that your water heater is on its last leg and ought to be replaced.

Electric vs. Gas Water Heaters: How To Choose?

Learn about the rewards and drawbacks of each fuel source, as well as newer, more efficient models of water heaters that could conserve you money in the long run.


If you‘ve had the very same warm water heater for more than ten years– the average life expectancy– a great plan would be to consider replacing it well before it breaks down and puts you in a mess.


Nevertheless, well before you start looking for a new hot water heater, you need to initially choose whether it should be gas or electric powered. While both types are very quite similar, there are noteworthy distinctions in regards to features and efficiencies in between the two.

The option in between gas and electric powered water normally comes down to the type of power presently present in the property.

Most times, homeowners simply go with whatever the property currently has. Practically every property has electricity, and many have both gas and electricity.


If you just have electricity, the choice is basic: You need to select an electrically powered water heater.


Electrically powered warm water heaters may not be the only choice for rural homeowners who do not have access to gas. They can utilize a gas water heater if they have gas.


Both gas and electric powered water heaters are graded by “input,” which is a measurement of how much gas or electricity is used each hour to heat up the water in the tank.


BTUs are used to measure gas input, while watts are used to measure electrical input.

Electric Gas Water Heater
  • A gas hot water heater’s average input ranking ranges from approximately 30,000 to 180,000 BTUs, depending upon size. The greater the BTU ranking, the quicker the home appliance will heat up water.

  • The power input of electrical water heaters ranges from around 1,440 to 5,500 watts, and the very same concept applies– the greater the wattage, the quicker the home appliance will heat up water.

Gas water heaters have greater starting costs than equal electrical water heaters, but they can also be less costly to operate.

The cost of a hot water heater varies mainly based on how large, energy efficient, and high quality your hot water heater is. Typically, the greater the cost, the much better the system will perform. A gas warm water heater, on the other hand, will cost more upfront than a comparable-size electrical warm water heater.


On the other hand, it is normally less costly to operate a gas hot water heater since the expense of gas is lower in a lot of places of the nation than the expense of electricity.


Depending upon where you are, you could prefer one over the other. Your monthly expenses are what will hurt you in the long run.


While the expense of a hot water heater is important, it should not be your only choosing point. Your choice should take into consideration the expense of efficiency, operation, and efficiency.

Electric water heaters (especially electrical heat pump water heaters) can have EF scores that are higher than gas water heaters.

The energy factor (EF) of a gas or electrical hot water heater is a measurement that compares the quantity of warm water produced daily to the quantity of fuel used.


The more dependable the water heater, the greater the EF value. While the performance of gas and electrical designs is usually equivalent, especially when comparing designs of the very same producer and size, certain types of electric-powered designs– including heat pump and hybrid heat pump models, as talked about below– have the performance edge.


The EF ranking of a hot water heater can be found on the product’s box or in the literature that includes it. Every brand-new conventional water heater need to have a bright yellow and black Energy Guide label that shows the product’s energy factor as well as the following information:


  • The type of fuel the water heater uses.
  • Its estimated annual operating expense.
  • The estimated quantity of energy used annual (BTUs or watts).
  • If the water heater satisfies Energy Star requirements for water heaters), an Energy Star business logo (.
  • Tank size (in gallons).
  • First-hour ranking (see below).


You will not have the ability to see the Energy Guide label if you shop online, but reliable vendors offer all technical requirements about the designs they offer, so you’ll have all the information you need to make an informed choice.

A number of types of gas and electrical water heaters are more energy-efficient by design.

Neither fuel type ensures the highest efficiency; however, suppliers have actually created extremely energy-efficient subcategories of water heaters for each type of source of power.

Efficient Gas Water Heaters

Energy-efficient Gas Water Heaters

Condensing hot water heaters catch and recirculate energy that would otherwise be wasted in order to enhance the whole efficiency of the unit.


Condensing units capture and recycle hot water vapor, in contrast to normal (non-condensing) gas water heaters, which route hot water vapor down a flue and exhaust it out of the house.


Naturally, these units have drawbacks and advantages:


  • Condensing hot water heaters are more costly than comparable non-condensing units.
  • Operating costs are lower for condensing water heaters.
  • Condensing hot water heaters have greater first-hour scores and recovery rates than non-condensing models.
  • A set up gas line is needed.
High Efficiency Condensing Water Heaters

Energy-efficient Electric Water Heaters

The heat pump hot water heater is the peak of performance in electrical water heaters. This water heater is most suited for usage in warm areas since it draws heat from the air.


Heatpump models are more costly than non-heat pump ones (about $800 to $2,500 more than a general electrical model), but they are the most energy-efficient hot water heaters on the marketplace today.


Hybrid heat pump hot water heaters make it possible for the customer to select multiple working modes for various situations, hence increasing the product’s performance.


Most hybrid heat pump units, for example, provide a “holiday” mode that reduces operating expenses while nobody is at home.


Depending upon the model, selecting a hybrid heat pump over a normal water heater can conserve you up to 80% on hot water expenses. These products, however, need to be set up in an area of a minimum of 1,000 square feet, so while they appropriate for a big garage, they are not practical for a small utility closet.

Tankless Water Heaters

Efficient Water Heaters Powered by Gas or Electrical energy

Tankless hot water heaters, often referred to as “on-demand” or “point-of-use (POU)” water heaters, are readily available in both gas and electrical designs. When a faucet or a device is switched on, these smaller sized configurations suck water in through a heating element.


They can be up to 35% more energy highly effective than standard tank-type hot water heaters since they heat up water as you utilize it. Condensing or non-condensing gas tankless water heaters are readily available.


They have a limitation on how much warm water can be pumped out simultaneously, so choose the unit based upon how much warm water you’ll need. Due to the fact that they do not hold warm water, recovery and first-hour scores do not apply (see below).


Instead, tankless hot water heaters are sized based upon their “circulation rate,” which is determined in gallons per minute (GPM).

Gas water heaters tend to heat up faster.

Because of its combustion, gas generates heat quicker than an electric heating element. As a result, the recovery rate and first-hour ranking (FHR) of gas hot water heaters are higher than those of comparable electrical units with the very same producer and tank size.

(You can find these scores on the system’s description on the merchant’s or producer’s site).

  • The amount of water that the system can heat up an extra 90 degrees Fahrenheit with time is suggested by the recovery rate, which is determined in gallons per hour (GPH)
  • When the water in the tank is totally heated, the FHR shows how much hot water the heater can give up the first hour. The greater the FHR, the more effective the water heater.

An electrical water heater installation could be a Do It Yourself job.

An inspired do-it-yourselfer with standard electrical skills can normally change an electric hot water heater and save money on installation expenditures (about $350 to $450, depending upon the location locations of the nation will have varying rates).

Replacing a gas hot water heater, which needs removing and reconnecting a gas line, is an entirely different process. Gas lines need to be moved during installation, and gas and gas hot water heaters (other than condensing models) need to be vented to the exterior.

This is not a job that the average property owner has the ability to do; instead, it is suggested that the installation be handled by an expert.


If a home presently has a gas water heater, a local plumber will charge $400 to $550 to remove the old system and install the brand-new one, no matter whether it is a tank or tankless model. Nevertheless, switching from electrical to gas may cost an extra $1,500 to $2,300 in installation costs due to the requirement to run a new gas line and install venting.


The type of water heater (tank or tankless, for example), rather than the source of power, will choose for how long it lasts.


Tank hot water heaters last 10 to 13 years on average for both gas and electrical, whereas tankless units can live up to 20 years or more. Electric heat pump water heaters have a life-span of 12 to 15 years on average.


Whatever type of water heater you choose, whether gas or electrical, you will get the most useful life out of it if you constantly follow the producer’s annual service and upkeep schedule.
