Changing a Hot Water Heating Unit? Know the Best Time

When to replace the Hot water heater in your residential property?

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


A hot water heater’s tank must last six to twelve years with better upkeep, however, tankless hot water heater can last as much as twenty years.


For the most up-to-date due dates, you must consult your warranty.

So, how can you tell when it’s time to replace your hot water heater? A hot water heater that is routinely maintained and fixed as required can last for a lot of years. You‘ve most likely been utilizing the exact same water heater since you moved into your present residential property.

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


You might initially think about having the water heater fixed, but there are indications to look for that will help you determine whether to replace the hot water heating system in your residential property.

Here are 5 indications it’s time to replace your water heater:

None of these symptoms are a sure signal that it’s time to replace the hot water heater. Before making a choice, always seek advice from a competent plumber. The plumbing service can advise you if the repairs are still beneficial.


In a normal residential property, for how long do hot water heater last? The majority of systems have a life expectancy of 15 to 20 years. Despite the fact that the present water heater remains in good working order, it is normally best to install a brand-new system if it is more than 20 years old.


A drop due to age will occur quickly, and it is a good idea to get ahead of it by purchasing a brand-new water heater.

The volume of hot water reduced

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


You should not notice corrosion on your water heater until it’s rather old. If it does occur, it is normally irreversible, and you will have to replace your water heater.

Water reddish staining

This shows that the interior of the hot water heating unit tank is rusting if you turn on the taps and see a reddish tint to the hot water.

Frequent repairs

Monitoring the overall number of times a hot water heating system requires to be fixed in a year is a great way to figure out when it is time to replace it.

Your residential property’s water heater needs to only need to be serviced two times a year.

Electric vs. Gas Water Heaters: How To Pick?

Learn more about the benefits and disadvantages of each fuel source, along with newer, more effective types of hot water heater that might save you cash in the long run.


If you‘ve had the exact same hot water heating system for more than 10 years– the average lifespan– a good plan would be to think of replacing it well before it breaks down and puts you in a mess.


However, well before you start looking for a brand-new hot water heater, you must initially determine whether it needs to be gas or electrical. While both types are extremely much the same, there are noteworthy distinctions in regards to features and performances between the two.

The choice between gas and electrical water normally boils down to the kind of power currently present in the residential property.

The majority of times, house owners simply opt for whatever the residential property currently has. Nearly every residential property has electrical energy, and lots of have both gas and electrical energy.


If you just have electrical energy, the choice is easy: You need to choose an electric powered water heating unit.


Electric powered hot water heating units might not be the only alternative for rural residents who do not have access to natural gas. If they have gas, they can utilize a gas water heating system.


Both gas and electrical hot water heater are graded by “input,” which is a measurement of how much gas or electrical energy is utilized each hour to heat up the water in the tank.


BTUs are utilized to determine gas input, while watts are utilized to determine electrical input.

Electric Gas Water Heater
  • A gas hot water heater’s average input score varies from approximately 30,000 to 180,000 BTUs, depending upon size. The higher the BTU score, the faster the appliance will heat up water.

  • The power input of electrical hot water heater varies from around 1,440 to 5,500 watts, and the exact same principle uses– the higher the wattage, the faster the appliance will heat up water.

Gas hot water heater have higher starting costs than equal electric powered hot water heater, but they can also be less expensive to operate.

The price of a water heater differs primarily based on how big, efficient, and high quality your hot water heater is. Usually, the higher the price, the better the equipment will perform. A gas hot water heating system, on the other hand, will cost more upfront than a comparable-size electric powered hot water heating system.


On the other hand, it is normally less expensive to operate a gas hot water heater because the cost of natural gas is lower in many places of the nation than the cost of electrical energy.


Depending on where you are, you might prefer one over the other. Your monthly bills are what will impact you in the long run.


While the cost of a water heater is vital, it needs to not be your only choosing factor. Your choice needs to take into consideration the cost of efficiency, operation, and performance.

Electric powered hot water heater (mainly electric powered heatpump hot water heater) can have EF rankings that are higher than gas hot water heater.

The energy factor (EF) of a gas or electric powered hot water heater is a measurement that compares the amount of hot water produced daily to the amount of fuel used up.


The more efficient the water heater, the higher the EF value. While the efficiency of gas and electric powered models is generally comparable, particularly when comparing models of the exact same maker and size, certain kinds of electric-powered models– including heat pump and hybrid heat pump systems, as discussed below– have the efficiency edge.


The EF score of a hot water heater can be looked for on the product’s box or in the literature that comes with it. Every brand-new standard water heater must have a bright yellow and black Energy Guide label that shows the product’s energy factor along with the following information:


  • The kind of fuel the water heater uses.
  • Its expected yearly operating cost.
  • The expected amount of energy utilized yearly (BTUs or watts).
  • If the water heating system fulfills Energy Star requirements for water heating units), an Energy Star emblem (.
  • Tank size (in gallons).
  • First-hour score (see listed below).


You won’t have the ability to see the Energy Guide label if you go shopping online, but reliable vendors supply all technical specs about the models they offer, so you’ll have all the details you need to make an educated choice.

A number of kinds of gas and electrical hot water heater are more energy-efficient by design.

Neither fuel type ensures the highest performance; however, suppliers have produced extremely energy-efficient subcategories of hot water heater for each kind of source of power.

Efficient Gas Water Heaters

Energy Efficient Gas Water Heaters

Condensing water heaters catch and recirculate energy that would otherwise be squandered in order to enhance the whole performance of the appliance.


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


Obviously, these systems have advantages and drawbacks:


  • Condensing water heaters are more expensive than comparable non-condensing systems.
  • Operating costs are lower for condensing water heaters.
  • Condensing water heaters have higher first-hour rankings and recovery rates than non-condensing units.
  • A set up gas line is needed.
High Efficiency Condensing Water Heaters

Energy Efficient Electrically Powered Water Heaters

The heatpump hot water heater is the peak of efficiency in electric powered water heaters. Because it draws heat from the air, this water heater is most suited for use in warm locations.


Heat pump units are more expensive than non-heat pump ones (about $800 to $2,500 more than a basic electric powered model), but they are the most energy-efficient water heaters on the market today.


Hybrid heatpump water heaters enable the consumer to choose several working modes for various circumstances, thus increasing the product’s efficiency.


The majority of hybrid heatpump systems, for instance, use a “holiday” mode that decreases overhead while no one is at home.


Depending on the model, picking a hybrid heatpump over a regular water heater can save you as much as 80% on hot water bills. These devices, however, must be installed in an area of a minimum of 1,000 square feet, so while they are suited for a large garage, they are not suited for a small utility closet.

Tankless Water Heaters

Highly Effective Water Heaters Powered by Gas or Electricity

Tankless water heaters, typically known as “on-demand” or “point-of-use (POU)” water heaters, are readily available in both gas and electrical models. When an unit or a faucet is switched on, these smaller setups draw water in through a heating element.


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


They have a limit on how much hot water can be pumped out simultaneously, so pick the device based on how much hot water you’ll require. Because they do not hold hot water, recovery and first-hour rankings do not use (see listed below).


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

Gas water heaters tend to warm up more quickly.

Because of its combustion, gas generates heat faster than an electrical heating element. As a result, the recovery rate and first-hour score (FHR) of gas water heaters are higher than those of equivalent electrical systems with the exact same maker and tank size.

(You can locate these rankings on the unit’s description on the seller’s or maker’s site).

  • The quantity of water that the unit can heat up an additional 90 degrees Fahrenheit with time is shown 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 heating system can give in the first hour. The higher the FHR, the more effective the water heater.

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

A motivated do-it-yourselfer with standard electrical skills can normally replace an electrical hot water heater and conserve installation expenditures (about $350 to $450, depending upon the location areas of the nation will have differing rates).

Changing a gas hot water heater, which requires reconnecting a gas and disconnecting line, is a completely different procedure. Gas lines must be moved during installation, and natural gas and gas water heaters (other than condensing versions) must be vented to the outside.

This is not a project that the average house owner is able to do; instead, it is advised that the installation be dealt with by an expert.


If a house currently has a gas water heater, a plumbing technician will charge $400 to $550 to eliminate the old unit and install the brand-new one, despite whether it is a tank or tankless model. Changing from electrical to gas may cost an additional $1,500 to $2,300 in installation costs due to the requirement to run a brand-new gas line and install venting.


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


Tank water heaters last 10 to 13 years on average for both gas and electrical, whereas tankless devices can live up to 20 years or more. Electric heatpump water heaters have a life expectancy of 12 to 15 years on average.


Whatever kind of water heater you pick, whether gas or electrical, you will get the most beneficial life out of it if you constantly follow the maker’s yearly service and upkeep schedule.
