Aside from hygiene, it’s a recognized truth that hot and cold showers provide us with distinct advantages. A cold shower energizes us and gives us more motivation to take on the day, while a hot shower relaxes us, enhancing blood flow to joints and muscles and improving sleep.

Most of us need both types of showers in our lives, and we want to be able to switch between them as needed. Thankfully, we now have the ability to do so, owing to a flexible piece of equipment known as the water heater.

These inventions, as essential as they are, appear to receive far less attention than other household appliances such as the refrigerator and air conditioner. So, if you’re thinking about buying a water heater for the first time or replacing an old one, this article will tell you all you need to know.

First, let’s dive into the individual health benefits of both hot and cold showers for you to gain a clearer understanding of how important they may be for your life.

Health Benefits of Cold Showers

Although having a cold shower is not a pleasant experience for most, especially first thing in the morning, it can have some health advantages.

Improved Blood Circulation

Cold water makes the blood vessels on the skin’s epidermis contract. This redirects blood flow away from the skin’s surface. In fact, a  study discovered that having a cold shower after exercise may enhance overall hydration by chilling the body significantly.

Blood arteries in deeper bodily tissues widen as blood flows away from the surface. This increases circulation in deeper tissues.

Lowered Cortisol Levels

Cortisol is the “fight-or-flight” hormone released by the body in reaction to stress. Reducing cortisol levels in the blood may consequently aid in stress reduction. Researchers have discovered that when people immerse themselves in cold water, their cortisol levels drop rather significantly.

Reduced Pain Levels

Cold showers and baths, according to research, causes an instinctive pain response known as stress-induced analgesia. Diminished pain response during or after exposure to stressful stimuli, such as cold water immersion, is referred to as SIA.

Diminished Sports-related Muscle Pain and Swelling

Prior research from 2009 looked at the impact of cold showers on athletes’ physical performance. Following their respective sporting events, some athletes were given cold showers, while others were given tepid showers.

The researchers found no changes in later physical ability between the two groups, nor in the degree of muscle injury or inflammation reported by the subjects.

However, sensations of muscular pain and overall weariness were much lower in the cold shower group. This psychological influence may be advantageous during competitive sports.

Health Benefits of Hot Showers

It is difficult to find folks who do not appreciate hot showers. After all, who can resist a soothing sensation as they clean up after a hard day at work? These showers aren’t only pleasurable, they’re quite healthy to engage in, too.

Better Cardiovascular Health

Warm showers appear to enhance blood flow in adults with chronic heart failure, according to a 2014 hydrotherapy research. This is due to the natural expansion of blood vessels caused by high temperatures.

Other researchers looked at the impact of hot showers on arterial stiffness, which happens when the arteries in the body become less flexible. Arterial stiffness is a primary contributor to cardiovascular disease atherosclerosis, which can result in high blood pressure.

Improved Muscle and Joint Health

As previously said, hot showers may increase blood flow, which can help relieve tight joints and fatigued muscles. Meanwhile, cold showers can help decrease inflammation and numb discomfort.

Improved Brain Health

One research published in 2018 looked at the impact of hot showers on the brain-derived neurotrophic factor (BDNF). BDNF is a protein that performs a variety of critical tasks in the brain and spinal cord.

The research was relatively tiny, with only eight males participating. One group got a 20-minute hot shower that reached 42°C. The other group got a 20-minute bath in cold water.

BDNF levels were considerably more significant in participants who took the hot shower. The researchers concluded that the hot bath-induced hyperthermia led to enhanced BDNF production.

Sleeping Better

Taking a hot shower or bath before bedtime is recommended by many health-oriented organizations as a technique to promote sleep.

A hot shower may increase sleep quality because of how the body relaxes when bathing and the subsequent drop in body temperature.

If you arrived at a conclusion that you need one of these water heaters in order to enjoy the best of both worlds in showering, keep reading to find out where to get one.

Types of Water Heaters

When it comes time to buy a water heater or replace an old one, you may quickly learn that not only are there various types of water heaters available, but each has its own set of advantages and disadvantages. With so many current options on the market, it’s always preferable to be informed about your options rather than relying on chance or a possibly biased “specialist” salesman.

Water heaters are classified into four main types. Each has its own innovative qualities and energy efficiency, so it’s well worth your time to learn about them all before buying.


1. Conventional Water Heater

Conventional water heaters are one of the most popular types. They have a large insulated tank that stores and warms the water.

Pros:

  • Lower initial cost- Unless you choose an ultra-modern model, you’ll likely pay significantly less on the initial upfront expenditures of a traditional water heater than you would for any of the other options.
  • Efficient in all climates- No matter where you live in the globe, you can be confident that a conventional water heater will perform flawlessly. It will give consistent and smooth operation if adequately maintained.
  • Lower installation expenses- In addition to having attractive starting prices, traditional water heaters are also affordable to install. This, of course, is dependent on where you intend to build and if you will require plumbing, gas, or electrical setups. 

Cons:

  • Increased energy waste- Because traditional water heaters include a steady supply of warm water, they are constantly consuming energy to keep the temperature stable.
  • It takes up a lot of space- There’s no getting around the size of a traditional water heater. Because they are intended to house a reservoir of warm water, they tend to be on the bigger side of the size spectrum.
  • Water damage vulnerability- One of the most severe fatal defects of traditional water heaters is their vulnerability to water damage. If you fail to do regular routine maintenance checks, you may wind up dealing with rust and corrosion, which can jeopardize the operation and health of your water heater. This might potentially result in substantial and costly water damage to your house.

2. Tankless Water Heaters

Through super-heated coils, tankless water heaters may create immediate hot water. These coils fill up with water as soon as you turn on the water, providing near-limitless hot water for your house.

Pros:

  • Instant hot water- Rather than having to wait for chilly water to change into warm water and warm to turn into hot, tankless water heaters deliver instant hot water when you need it. Because these models only heat water as needed, they consume less energy overall, especially when compared to a traditional heater.
  • Saves space- One of the most noticeable advantages of a tankless water heater is its small size. Tankless variants do not require any cumbersome storage space because they do not require a continual reservoir of water. This allows them to be easily mounted on walls or stored in small nooks and crannies.
  • Lower monthly costs- Installing a tankless water heater in your house significantly lowers your monthly expenditures thereby saving you thousands of pesos on a yearly basis. The reduced requirement for energy flow allows you to reap the benefits of your power-saving decision.

Cons:

  • Higher initial cost- These types of water heaters are considerably above average. While there are several advantages to switching, people on a tight budget will have to wait a while before making up the cost difference.
  • There is no discernible advantage over comparable low-cost alternatives- Tankless water heaters are much more expensive than a variety of other water heater options, but they do not always come with highly outstanding bonuses that are difficult to get with less costly alternatives. 

3. Heat Pump Water Heater

These types operate without generating heat directly, often referred to as hybrid water heaters. The only electricity utilized is to move heat from point to point by using the heat in the earth and surrounding air.

Pros:

  • Heat pump water heaters use around 60% less energy than traditional water heaters. Though heat pump heaters have a higher average cost than tankless heaters, you’ll realize the benefits of energy savings sooner.
  • Heat pump water heaters are perhaps the most energy-efficient alternatives to gasoline, oil, and electric water heaters in the long run. Heat pump water heaters hold a lot of potential for people looking for a water heater that is both energy and cost-effective.
  • Heat pump systems are incredibly low-maintenance when it comes to routine checkups. Maintaining your hybrid system may be simply self-assessed and accomplished with only a once-a-year check. A professional inspection of your system is advised every 3 to 5 years.

Cons:

  • Heat pump water heaters have a life duration of around ten years on average. Heat pump water heaters pale in comparison to solar and tankless heaters, which have an average lifespan of 20 years, and conventional systems, which have an average lifespan of 10-15 years.
  • Heat pump water heaters need at least 1,000 cubic feet of area to function safely and efficiently.
  • This carbon-neutral device will undoubtedly turn off anyone hoping for a water heater that minimizes their carbon impact.

4. Solar Water Heater

Solar water heaters rely on the sun’s energy. They function by transferring energy from roof-mounted panels to a closed-loop system that links to a water tank, which subsequently heats the water.

Pros:

  • Solar heaters are by far the most energy-efficient water heaters available today since they use renewable energy. Solar power may be harnessed everywhere the sun’s rays reach on any given day since it is entirely reliant on sunlight.
  • Lower utility bills- Solar panels are not only highly eco-friendly but they are also relatively cost-effective. While the initial installation cost may be offputtingly high, switching to solar may dramatically lower your water and power expenses.

Cons:

  • Only suitable for sun-drenched environments: Upgrade to a solar water heater if you live in a shaded location or in a climate where there are more wet days than sunny days.
  • Installation costs- One of the most significant disadvantages of solar water heating is the expense of installing solar panels. If you’ve decided to go solar, there are a variety of financing options available to help you get started.
  • Rooftop area requirements- The more power you consume from your solar panels, the more panels you will require. The more solar panels you have, the more roof space you’ll require. If your house is tiny, your roof might not be able to support the amount of panel electricity you need.

Important Factors to Consider Before Buying

Knowing the type of water heater you need or want might be beneficial, but here are the things you have to consider further before handing over your cash.

 

1. The Tank vs. the Tankless

Tank water heaters are available in two varieties: gas and electric. Both gas and electric heaters are insulated and can keep the inside water warm. Furthermore, both contain a thermostat for temperature control. The primary distinction between a tank and a tankless water heater is the simplicity of operation and energy efficiency. Because they do not store heated water, tankless water heaters appear to deliver an infinite hot water supply. Instead, it warms water on demand or as needed.

2. Dimensions/Storage Capacity

Your family’s demands should ultimately influence the type of water heater you pick. That being stated, the size of your water heater should be determined by the number of people in your home. If you want a continuous supply of hot water for all family members, you need to think about the capacity of your water heater.

3. Energy Conservation

Consider purchasing an energy-efficient water heater to save money on your utility expenses. This not only saves cash but also makes the best use of energy. Choosing an energy-efficient water heater can help you save up to 60% on your power cost.

4. Preferences for Design

When it comes to water heaters, there is virtually no shortage of alternatives in today’s market. Having said that, you have a plethora of options at your disposal. This does not, however, imply that you can simply pick one that performs the job. Choose the most excellent water heater for your area to ensure that it complements the overall design and appearance of your house.

5. Budget

Prior to purchasing a water heater, you must evaluate your budget like you would any other purchase. Before you go to the store or the site, make a rough estimate of the yearly running and maintenance costs. First, compare numerous water heaters to see which one is the best in terms of quality, price, and features.

6. Warranty

Different manufacturers provide varying lengths of warranty. Choose one that you are pleased with to guarantee that you receive enough repair and maintenance assistance for your product if any components are damaged.

Installation

While this guide strives to assist you as much as possible, the people behind it simply do not believe that a DIY water heater installation is safe unless you are a qualified or experienced expert yourself. The chances of this being a good idea are pretty slim. Trust the specialists with your water heater installation to ensure a proper installation. You wouldn’t want to endanger yourself or your family.

Most home improvement projects are stressful, but installing water heaters is incredibly demanding. Working with plumbing, moving heavy equipment, and ensuring wiring are secure and accurate takes time, especially if you’re not used to it.

When it comes to this service, Teko is perhaps the finest in the market. You may arrange a service in three simple steps, and a specialist will be dispatched straight to your door! Install your water heater without ever leaving your house.

Having said that, if you’re determined to do this on your own, you’re proficient with basic plumbing tools, here are the steps to go about it. 

1. Take off the Front Cover

Before installing the new tankless unit, gently remove the front cover with a screwdriver. After you’ve removed all of the screws, store them somewhere you won’t lose them. All of these screws are required for your water heater to perform correctly. Remember that wires may be placed between the cover and the device. Unplug them carefully before removing the lid completely.

2. Mount the Water Heater

Mounting the water heater may be accomplished with a combination of screws and the provided mount. Stick to the instructions that came with your equipment.

3. Connect the Pipes

After you’ve done mounting the heater, it’s time to connect the pipes that deliver water to and out of it. For sure, you received an installation schematic with your equipment, which you should consult to establish where the hookups should be made.

Stainless steel is the ideal pipe material for a tankless water heater. It can endure high temperatures without compromising the system’s accessibility or flexibility. If you don’t have stainless-steel pipes, copper and PVC plumbing are viable substitutes. When you choose a flexible tube made of stainless steel, you can be sure that the connections can be simply disconnected, which is helpful if you wish to clean them on a regular basis.

4. Set up the Flow and Pressure Valves

After the connections have been established, the flow and pressure valves must be installed. Flow valves are easy to set up. When repairs are required, you may turn off the water supply to the heater rather than having to cut the water supply to your entire home.

5. Bleed the hot water system

The water heater should be fully installed and functional at this point in the procedure. However, you should still execute the bleeding process before turning on the hot water system. All hot water outlets in your home should be opened to help remove any air from the system. Keep them open for a few minutes, as the bleeding process should be finished.

6. Before attaching the cover, inspect the electrical connections.

It is critical that you verify the electrical connections to your water heater for your safety. Check that these connections are correctly wired and connected to the correct terminals. The lid should then be reattached using all of the previously removed screws. The installation is practically complete once the cover has been appropriately fitted on the device.

7. Turn on the circuit breaker

It’s okay to turn on the circuit breaker now that you don’t need to work on the heater.

8. Examine the temperature and the outlets

After you’ve turned on the water heater, you’ll want to customize the system’s temperature settings. These devices may get quite hot when set to their maximum settings; therefore, it’s best not to use them to avoid burns.

Precautions for Using

It’s probably not your first time to use one of these, so some detailed instruction on how to do so will be an insult to you. However, there may be ill-advised habits that we are all accustomed to that might harm your device and shorten its lifespan. When working with your machine, consider this section a safety guideline.

For starters, it is advised that you read your owner’s manual before anything else, as most safety instructions are there, too. And while the precautions we are about to discuss will be of utmost importance, there might be instructions in those manuals that are brand-specific. So, do your due diligence. We understand that this sounds like a lot of work, but the return is being able to utilize your appliance for much longer and possibly even pass it down to the next generation. Please read the precautions below.

  • The water heater’s maintenance requirements are modest. For indicators of deterioration or failure, periodic inspections and testing are always suggested. 
  • Any damage, cracks, leaking, or weakness should be addressed and repaired as soon as possible.
  • Be careful not to overtighten any of the connecting points. This might result in significant internal damage to the device.
  • Keep in mind that water heated at higher temperatures accumulates minerals considerably faster than water heated at lower temperatures.
  • Installing manual shut-off/maintenance valves on the water heater’s input and output will allow you to flush the device with a descaling solution.
  • If the water supply has an extremely high degree of mineralization, we propose routine maintenance once a year or every six months.
  • Every six months, clean the pre-filter on the inlet. To eliminate any particles, gently give this a wash.
  • When doing any type of maintenance on the water heater or the home’s plumbing system that may introduce air into the plumbing pipes, it is critical to turn off the water heater and purge the air out of the lines before re-powering the unit.

 

Diagnosis and Repair

As with human ailments, our appliances can show indications of underlying problems. While we recommend contacting your appliance service provider as soon as you spot a problem with your water heater, there are some difficulties that you can solve or at least identify to some extent.

Here are some common water heater problems and their causes, as well as some troubleshooting advice. We’re urging you once again to consult your manual for brand-specific issues and solutions.

1. No hot water and the display does not light up.

  • It could be a power outage or faulty wiring.
  • Check the power supply.
  • Check the circuit breakers.
  • Make sure the breakers at the main electrical panel are on.
  • You may have a defective breaker, or the unit may be wired incorrectly.
  • Make sure the shutoff valve on the unit’s incoming water supply line is fully open.
  • The flow rate needed to activate the heating element (0.5 GPM) may not have been reached.
  • Increase the flow rate from the water supply source.
  • Clean the filter screen on the unit’s water inlet.

2. No hot water and the display does light up.

  • Make sure to shut all power on your breaker panel before attempting to reset the unit. 
  • Reset the unit.

3. Water is heated but not hot enough.

  • The water flow rate exceeds the heating capacity of the heater. Reduce the water flow rate at the faucet or slightly close the shutoff valve on the unit’s incoming water supply line.
  • Voltage might be less than 240 volts. The heating elements on your water heater are designed for 240 volts. When used with a lower voltage, they produce less heating power. You may need to upgrade to a larger input heater.
  • If it’s a new installation, double-check the wiring to confirm that it is correct.

4. Water is too hot.

  • The water flow rate through the heater is too slow. Increase the flow rate at the water outlet.
  • The temperature setting might be too high. Switch to a lower temperature setting.

5. Heater shuts off during use.

  • It could be a power outage or faulty wiring.
  • Check the power supply. 
  • Check the circuit breakers.

6. Water stops flowing.

  • It could be a possible blockage in water pipes or hoses.
  • Make sure the main water line valve is fully open and there are no obstructions in the water supply line.

Disposal

Most electric tankless water heaters are relatively small appliances, and they can be thrown away with ease along with your other trash. Needless to say, you must observe proper segregation in doing so. 

If the old water heater is still working, and you’re simply buying a new one to upgrade, consider selling or donating it to a worthy organization. This is an efficient way to dispose of your old heater. If it’s not functional anymore, consider contacting your local junk shop and see if they would take it off your hands for scraps.
