Tips for water heaters

You do not think about your water heater daily, but you will certainly know if it malfunctions. A water heater ensures that your water is at the ideal temperature, from washing the dishes to taking a bath. Not to mention a water heater can have a substantial impact on your expenses. As a matter of fact, heating water takes up to 20% of a household’s energy costs.

When it is time to install or replace your water heater, it is imperative to ask the experts – Αποφρακτική Αντωνίουthe right questions in order to find the best unit for your household and budget.

The Type of Fuel Required

Ensure you know the kind of fuel your current heater uses so that you can get one that utilizes the same. While it’s possible to move to a different source of fuel, it will come at a substantial cost and depends on your home. Natural gas and electricity are the most common sources of water heater energy. Depending on where you reside, you can ideally use solar power, geothermal energy, or other forms of gas like propane.

Simply put, the available energy will dictate the type of water to install and can ideally have an impact on the ongoing water heating costs.

Tank or Tankless?

This is one of the most basic questions for anyone on the market for a water heater. The answer, however, depends on both your requirements and budget. A tank water heater is a more conventional model that you are likely using. As the name implies, hot water is kept in the tank, where it is constantly kept warm until it’s ready for use.

A tank water heater usually has a lower upfront cost, but it can lead to higher energy expenses in the long haul. On the contrary, tankless water heaters are expensive upfront, but they have lower operating costs because the water is only heated when required. They are also more compact as they do not keep a reserve of water.

According to a – Αποφράξεις Αντωνίου Αθήνα review, tankless water heaters may be more energy and cost-effective, but they ideally have some downsides. They take longer to heat water compared to their counterparts as there’s no hot water in reserve, waiting for use. This can be frustrating for people with huge families or those who are always in a hurry. Tankless units can also be problematic during winter.


Energy Efficiency

As said from a water heater guide, it is also important to ensure your unit is energy-efficient and an energy-star symbol is the first thing to look for in this regard. Picking an energy star rated water heater is a great way of knowing if you’re getting a unit that will conserve energy while still performing optimally. The energy factor or EF is another important element to consider, as it shows the efficiency of your system. The higher this number, the more efficient the unit

10 Water Heater Tips

Below are several money-saving water heating tips (many supported by that will help lower those large water heating bills.


Though many manufacturers set their water heater thermostats at 140°F, most typical households are comfortable with 120°F. Try taking a shower after you’ve adjusted; it’s unlikely you will notice a substantial difference in the temperature. Not only does this small decrease cut costs, but it also reduces scalding and slows mineral build-up and corrosion in your heater and pipes.


Insulating your storage tank (whether it’s electric, natural gas, or oil) helps to reduce heat loss and prevents the unit from turning on as frequently. Be careful to follow the manufacturer’s recommendations which include not covering the heater’s thermostat, burner, and the top and bottom. Call your local plumber for assistance in insulating your hot water tank.


Heat traps allow the flow of cold water into the tank but prevent heated water and unwanted convection to flow from the unit. Most modern water heaters are designed with built-in heat traps. But if your unit is more than 10 years old (and in good condition), installing a heat trap is a viable option. Ask our professional plumber – Αποφράξεις Αντωνίου – for more information.



While this may seem like an obvious tip, using cold water for most laundry loads (especially during the rinse cycle) and basic grooming (brushing teeth, washing hands, etc.) will go a long way in helping cut down your utility bill. Cold water is also healthy and good for your health and well-being.


A leaky faucet may seem like a minor nuisance, but it can waste water and money in a very short period of time. Repair any leaky faucet immediately (be sure to check the outdoor faucets as well). Did you know that 10% of homes have plumbing leaks that waste over 90 gallons a day! 


It’s a good practice to drain your water heater every year or so. Draining the tank helps to remove sediment that can impede heat transfer and ultimately lower the efficiency of the unit. While this is a relatively easy procedure, always make sure to follow the manufacturer’s directions. If in doubt, call a professional to help with water heater maintenance.


A traditional water heater tank is always running, which is a waste of electricity. Installing a timer to turn off your heater at night is a great way to help conserve energy – and could add years to the life of the unit. Call your local plumber for more information on water heater timers.


In addition to insulating the tank itself, consider adding insulation to the first 6 feet of both the hot and cold water pipes connected to the unit. This will prevent fire hazards and help conserve heat so that your system doesn’t have to work so hard to reheat it.


If your dishwasher or washing machine is more than 10 years old, you might consider replacing it with a new, more energy-efficient model. There are many new designs on the market that use less water and are much more efficient than what was on the market even a decade ago.


It’s a good idea to replace your water heater if it is more than 10 years old. An old water heater is not only inefficient but could also cause irreparable damage if it leaks or bursts.

When Should I Replace My Water Heater?

If you are thinking about replacing your water heater, there are many different options available to you, including tankless water heating. By only heating water when you require it, a tankless water heater can save you $70-$80 per year, which adds up over its 20+ year lifespan.
