Electric bidets are also known for their magical ability to heat water. But have you ever wondered - how do bidets heat water? Or about different water heating methods used by bidets? Because if you're a curious cat like me, you're about to have the time of your life. 

Today, let’s discuss various types of water heating methods used by today's bidet seats in this article, including the benefits and issues associated with them. So without further ado, let's talk about how bidets work and how do bidets heat water:

How Is Bidet Water Heated?

We all know that a bidet toilet seat provides relaxation and comfort, right? But if you've ever used a bidet that offers only cold water or doesn't come with a friendly, toasty, preheated seat, you know the situation can be less than blissful.

Warm water bidets with a built-in toilet seat warmer have become the rage in recent years. Almost all modern bidet toilet seats offer warm water washing. However, the method of heating water differs significantly between different bidet toilet seats.

Generally speaking, there are three kinds of bidets: one with a tank-type heater, a tankless on-demand heater, or a hybrid of both. The water heating method of a bidet differs depending on its type.

We'll walk through each water heating design offered by non-electric and electric bidet toilet seats, but first, let's talk about their differences. 

Electric Vs. Non-Electric Bidet Systems

Even though both types of bidet attachments offer a more hygienic experience than toilet paper alone, there are distinct functional differences between these two types of bidets that ought to be understood before choosing the one that best meets your needs.

An electric bidet has several perks to offer you, and if you're looking for a luxe bathroom experience and are willing to splurge on it, it is the best option for you out there. Some of the advantages of an electric bidet are:

  • It Is Easier To Use Electric Bidet Models For Individuals With Limited Mobility And Strength.
  • The Addition Of A Warm Air Dryer Feature Can Eliminate The Need To Use Toilet Paper Completely.
  • There Are A Variety Of Models With Fully Adjustable Nozzles.
  • Right- And Left-Handed Individuals Alike Can Operate The Control Panel Or Remote.
  • The Heated Seat Option Ensures You Are Not Greeted By A Chilly Feeling When You Sit Down In Winters.
  • It Is Compatible With Most Toilet Models And Standard Toilets.

There are many non-electric bidet options, and there are many types of attachments for bidets. For example, bidet toilet spray is one of the most common types, similar to a detachable hand-held shower head standard in bathtubs and showers. 

If you're on a tight budget and want to make a switch, it is the best option available. Here are some of its advantages:

  • Any Toilet Can Accommodate A Non-Electric Bidet.
  • The Majority Of Non-Electric Bidets Attach To The Toilet Under The Toilet Seat.
  • They Are Incredibly Affordable And Come In Various Bidet Attachment Styles.
  • Just Like Electric Bidets, They Provide Thorough Cleaning.

To use and install an electric bidet, an electrical outlet close to the toilet must provide the power needed. For example, you may have to have someone install a power socket if you do not already have one. However, it may not always be possible to add an electrical outlet to the bathroom due to the layout.

Since non-electric bidets provide a lower comfort and convenience than electric bidets, they are easier to install. For example, it is possible to get warm water from a non-electric bidet by connecting the hot water line from a nearby sink or other fixture, but this may take some time as the cold water clears the bar.

Let’s finally unveil the mystery of how bidets heat water and what are the different water heating methods used by bidets.

How Do Bidets Heat Water? - Water Heating Methods Used By Bidets 

Bidets offer three kinds of water heating systems; a tank-type heater, a tankless on-demand heater, and a blend of both- a hybrid mechanism. All types provide warm water washing, but which is best for you? Are there any pros and cons to each type?

So let's dig into different kinds of water heating methods used by bidets and solve the mystery of how do bidets heat water:

1. Bidet Seats With Tank Type Water Heaters

A tank-type water heating system has several names like a tank water heater, a traditional water heater, or a reservoir-type water heater. 

Bidet seats with tank-type water heaters have an internal reservoir/tank that stores water. You can store heated water at your preferred temperature with a bidet toilet seat.  

The water is heated either by an electric heater or by the home's plumbing system. The water generally is heated immediately, but preheated water can also be stored for use later.

The heated reservoir will draw water from the bidet seat during the wash. After about 30 seconds, the warm water will gradually cool down until it reaches ambient temperature. The water tank of the bidet seat usually reheats entirely in about five minutes.

Several onboard tank systems allow you to control the stored water temperature. The system will either provide more warm water or mix it with cool water, depending on your preference. 

There is usually about one minute of continuous warm water provided by most of these tank systems before they run out and cool down again. 

People who prefer customised bidet temperature most often use tank water heaters. 

However, you can easily adjust the temperature to the current situation. The only drawback is that they take time to reheat. So let's take a look at the pros and cons of tank-type water heater:

Pros:

  • You Can Get Hot Water Immediately
  • Internal Water Pumps Result In Higher Spray Pressure
  • A Quicker Wash 
  • Due To Their Long Market Existence, Tanks Have A More Reliable Technology

Cons:

  • It Takes About 30 Seconds For Warm Water To Cool
  • Power Consumption Is Higher Than Tankless Types
  • Usually Larger In Size

2. Bidet Seats With Tankless Water Heaters

Popularly also known as the instant water heater and on-demand water heater system, tankless water heaters don't have a reservoir. Instead, warm water is only supplied once the system is activated, also known as an on-demand bidet. 

This type of water heating method used by bidets is made in various ways; One of the most common types is the 'on the fly' heater; it heats water as it passes. It uses the same principle used in most bathroom showers and under kitchen heaters.

The water heats up as it passes through the system; therefore, there is no need to preheat a large volume of water. Consequently, you'll save a lot of money on energy bills. Also, there is no chance of running out of water since the water gets heated as it passes through the coils.

They are ideal for individual and small family use since they heat up quickly. As the water passes through the bidet, it warms as it passes through it, so you won't ever run out of warm water. 

These bidets may offer a slight delay in delivering warm water. This is due to a bit of cool water present in the lines most of the time. You can either run the bidet for a few seconds beforehand to avoid this cold water hitting your bottom or look for a model with a pre-flushing system.

Despite their convenience, these bidets aren't the most energy-efficient, and many use a lot of electricity while they're operating. So weigh this model's pros and cons into consideration when shopping.

Pros:

  • Unlimited Supply Of Warm Water
  •  Greater Energy Efficiency
  • Can Change Warm Temperatures While Washing

Cons:

  • Initially, Water Is At Room Temperature Before It Is Heated
  • The Water Pressure Is Lower Compared To Tank-Type Water Heaters

3. Bidet Seats With Hybrid Water Heaters

A hybrid system offers some of the advantages of both systems and some additional features. Hybrid bidets typically provide warm water on demand, and having an onboard tank eliminates the shock factor associated with icy water sitting in your bidet lines.

Moreover, the water in these bidets continues to warm as it flows through the bidet system, ensuring that the water remains warm.

A hybrid heating bidet toilet seat combine tank and tankless water heaters. This heating method uses a smaller reservoir of preheated water while continuously heating the water during a wash. The result is unlimited warm water. Here are its pros and cons:

Pros:

  • Unlimited Supply Of Warm Water
  • It Offers A Higher Spray Pressure Than A Tankless Model
  • Comparatively, They Are More Energy-Efficient Than Tank-Type Bidets.

Cons:

  • It Consumes A Lot Of Energy Due To Preheating
  • The Water Pressure Is A Bit Low Compared To Tanks

That Should Clear Things Up!
