According to studies, water heating is among the top largest energy uses at home, accounting for more than 15% of one’s overall energy consumption. It is also an all-important appliance; on 2010, Energy Star reported that eight million water heater units were shipped and sold in the US alone. Modern technology, along with the change of consumers’ demands pushed for much changes with water heaters, when it comes to design and use. And from its different varieties (heat pumps, water tanks, tankless, gas pumps) we have discovered the Stiebel Eltron Tempra 24 as the present-day best water heater that seamlessly suits most homes and lifestyles.

Find the perfect water heater for your home

Residential water heaters are smaller units used in single and multifamily homes. This equipment relies on either of these three fuels: electricity, oil and natural gas. Gas water heaters have been predominant since the conception of this appliance. More than 50% of US homes make use of burned pipe natural gas, while 4% employs bottled propane gas. Electric water heaters come in second with more or less 40%.

There are water heaters that serve 50-gallon tanks and there are those that work with less. As of 2015, Energy Star has required gas-fired heaters to increase efficiency up to 30%, while tankless waters must meet 32% above the 2010 standard. Households, in return for this investment, can save from $40 to more than $250 in their utilities per year.

In this review, we will focus on residential water heaters and how to find the best choice that fits your home. If you already have a water heater installed, take note that its lifespan lasts in approximately 13 years. If the water starts to harden, or if your heater has become difficult to maintain, perhaps it is time to replace your equipment with something modern and efficient.

Why install a water heater?

Hot water is essential to every home, especially, for those living in colder areas. Before, consumers are forced to manually heat water when washing or bathing. Water heaters eliminate that unnecessary chore. This appliance provides a consistent supply of hot water to your sink and shower on demand. More than that, it also offers other functions, such as keeping your plumbing fixtures in shape.

Water and energy conservation are among the top features of an excellent quality water heater.

Modern water heaters with Energy Star seal promises greater efficiency as well as a big cut on the consumer’s utility bills. This means you save time, effort and money in enjoying hot water, consistently supplied in the temperature you prefer.

A look into Health and Hot Baths

Hot water and baths have long been associated with each other, primarily, for health reasons. A long, hot bath, Telegraph UK discloses, can help stimulate blood circulation and cell movement. Water pressure aids in relieving organs, which improves relaxation. Bath therapy, they call it, offers solutions for pain relief, skin condition and even arthritis.

It must be noted that hot baths are not only reserved for chilly weathers. The Daily Mail reveals a study that showed how diabetics could lower blood sugar levels by spending at least 30 minutes in a hot tub. This particular research, published by the New England Journal of Medicine, states that heat dilates blood vessels, helping the body to efficiently use its own insulin. The result: sugar levels are down by 13%.

The elderly also benefits in long, hot baths. 10 minutes of soaking, according to a Japanese study, improves their cardiovascular health. Other researches denotes that baths implemented with hydrotherapy helps keeps the body in its best condition, detoxifying it, reducing stress, and keeping it from potential viruses which might cause colds and flu.

And how to indulge in a good, hot bath? With a high-quality water heater. Further down, we’ll give you a list of remarkable water heaters to look at, but first, let’s discover the basics about these utilities so you’ll know which one you’ll need.

Types of Water Heaters

Heating water consumes about 15% of a home’s energy use. A big step from their previous models, modern day water heaters make use of 10-50% less energy, helping owners save carbon footprints as well as utility bills. The actual energy consumption, however, largely depends on family size and plumbing design.

If this is the first time you’ll install a water heating system in your property, you’re in luck; you’ll have many options available regarding the heating method of your equipment. You can look into many kinds of heating systems and choose which complies to your needs the most. Let’s take a closer look at the different fuel types.

  • Electric. Electric water heating systems are usually affordable and are easy to install–perfect for DIY homeowners who wanted to conveniently add a quick new utility in their property. However, be wary; this fuel type is perhaps the most expensive to run on continuous use. Households with four members typically requires about 120-160 liters for continuous systems. Despite these drawbacks, electric water heating systems can be installed anywhere in the home, and ranges within $200 to $1500.
  • Gas. This could be your best option, especially if you have the connection. This fuel allows consistent supply of hot water as needed, all credited to the fact that gas rates do not change throughout the day. Due to its venting requirements, gas-powered water heating systems are usually installed outdoors. Users can replace natural gas with LPG, but this also means raising utility costs. If you’re looking to buy this system, be prepared to invest about $800 to $2000, installation not included.
  • Heat pump. Working with the same principal like that of an air conditioner, heat pump water systems make use of the heat from the air and applies it to the tank. This outdoor-installed water heating comes with a tank and a compressor; the latter of which produces a loud sound. Thus, it is essential that you find a safe, secluded area for its installation, away from neighboring homes. Heat pumps are best employed in warm regions. These water heating systems require a tank that holds about 270-310 liters for a four-person household. If this is your choice heating system, you might need to invest $2000 to $4000.
  • Solar. Solar-paneled tanks transform sunlight into electricity which then heats the water. An ideal location for this water heating system is outdoors, with at least 4 square meters for the panel installation, and a 300-360-liter tank for storage. On days with less sunlight, a gas booster element, usually coupled with the system, will keep the water in the right temperature. While this can be the most expensive water heater–ranging from at least $2000 to $7000, your investment will be paid off with low utility costs.

Next, you’ll need to know which water tank fits your needs. This is where you’ll store your hot water until such time you require its use.

Storage tank. These insulated containers are common to all water heating system, regardless of the fuel. Usually made from steel, these tanks can last a full decade before requiring to be replaced. In order to know which type is best suited for your property, you need to know your water quality; some elements may corrode your tank, wearing it out easily.

Instantaneous flow. This type of water tank heats water as needed. It provides hot water at the rate of two to five gallons, enough for a warm dishwashing errand. However, it must be known that some models need a few seconds before water starts heating, especially when there’s a large distance between the tap and the water heater. Instantaneous flow tanks usually make use of gas and electric powered heating systems. It is cheaper to run, compared to the usual storage tanks. Instantaneous flow tanks are also called tankless water heaters.

How to buy the right water heater

If you are looking to buy a water heater for your home, you may want to look at this checklist to fully understand which one is right for you. Among the main factors you need to consider are:

  • The demand for hot water in your home
  • The location where the heater is to be installed
  • The chosen energy source (electric, propane, natural gas, heat pump, solar, etc.)
  • The purchase cost and other expenses associated with it (installation, maintenance, utilities, rebates)

While there are highly recommended water heaters in the market, there is no one size fit all heating system. Since this will be an investment you will use for a long time, it is good to discover your options. The Energy Star website is a good place to start, as they offer highly rated, well-made water heaters, marked for their efficiency in the environment and home.

Energy factor is also one of the best things to consider. The higher the number, the more efficient the appliance is. Many places have a required energy factor, stimulating the community in making the right decision in buying their water heater. Electric-powered heaters costs more than the ones fueled by natural gas. On this note, Energy Factor vary from product to product, depending on their models and fuels.

Don’t be afraid to shell out a bit more when it comes to water heaters; once you purchase the right item, you get more savings when it comes to operational and maintenance costs. Now that’s a smart buy!

Tip #1: Size matters

One thing you need to consider is if the water heater is enough to fulfill the needs of your entire household. One person typically uses about 50 liters of hot water a day, including long showers, laundry and dishwashing. A small household with 2 members may use a tankless water heater or a small gas-powered storage tank. Medium households, with about 4 members, will benefit from gas water systems.

Tip #2: Compliancy is key

Only buy water heaters that is compliant to your building code. Tankless systems are usually convenient options, but should you choose a gas-powered water heater, you might be asked to retrofit it according to the community standards.

Tip #3: Make that math

You may want to look into the water heater’s first hour rating, which denotes how many gallons can the system supply per hour. Usually, this is found on the manual. A 50-gallon tank may only supply about 35 gallons of hot water because rest is replaced by cold water in the first hour. From there, you can discern whether the water heater’s production satisfies your requirement. If you take less than 10 minutes of shower per day, you will be using about 17 gallons of hot water. From the 35 gallons denoted in the first hour rating, two people can enjoy a hot shower in an hour.

  • In order to reduce heat loss, insulate your exposed water pipes. You may also choose to insulate your water heater by enveloping it in an insulating blanket.
  • Keep 2 feet off your water heater. This is to avoid potential damage to the appliance.
  • If you’re using a tank storage, drain it a few times in a year to remove air and sediment.
  • Test your temperature relief valve with a quick drain. Watch out for small leaks; if found, have it repaired at once.
  • Check the anode rod and see if parts of it is exposed or is coated with deposits.
  • If you’re going out on a holiday, change the thermostat to its lowest setting to preserve energy.
