The 4 Types of Water Heaters: Which One Should You Get?

4 Mins read


When it comes time to buy a water heater or replace an old one, you will quickly learn that not only are there various types 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 choices 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.


  • 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. 


  • 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.


  • 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.


  • 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.


  • 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.


  • 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.


  • 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.


  • 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.


The bottom line is that there are a lot of considerations to be made, but it’s important not to overthink the process. Hopefully, you now have a better idea of which heater you should go with. Just remember to check into any energy or water efficiency incentives available for your area if you want to save money on utilities. We wish you all the best in your plumbing endeavors.
