The 7 Best Steam Generators in 2023 – In this article, we will review the best steam generators that you can buy in 2023. An overview of the top-rated models is provided, as well as their primary specifications, and major advantages and disadvantages. However, we should first take a quick look at the basics of steam generators, followed by a buying guide for anyone looking to purchase an excellent and efficient steam generator. Please read all the way through before making a decision.


Basics of Steam Generators 

Steam generators are low water-content boilers, similar to flash steam boilers. Construction is usually in the form of a spiral coil of water tubes arranged into a single coil. Circulation occurs once through and is pumped under pressure, as in a forced-circulation boiler. As they are constructed from narrow tubes without large drums or tanks, they are safe from explosions, even when they work at high pressures. Depending on how much steam is required at any given moment, the pump flow rate can be adjusted.

To ensure consistent output temperature, the burner output is throttled. The burner output needed is determined by the amount of water being evaporated. This can either be done by an open-loop control based on pump throughput or a closed-loop control that maintains the measured temperature.

Steam generators typically have less steel in their design than steam boilers, which use many smaller diameter tubes instead of a single tube coil. The feedwater is continuously pumped through the coil using a specialized feedwater pump. During a single pass through the coil, a steam generator converts incoming water to steam using a once-through, forced flow design. Hot gases transfer heat to the water as it passes through the coil, which causes the water to become steam. In order to achieve 99.5% steam quality, a steam/water separator has to be used since the generator design does not have a steam drum where the steam can be disengaged from the water.

As generators do not use a large pressure vessel like firetubes, they are often smaller and faster to start, making them ideal for situations where on-demand power is needed. While this is advantageous for energy efficiency, generators have low turn-down rates. They are therefore less effective in providing steam during periods of fluctuating demand.


Steam Shower Generator

The popularity of steam showers has grown in recent years. You can have your own spa treatment in the comfort of your home with a steam shower. Besides being soothing and relaxing, steam showers also offer several health benefits. Taking a steam shower after a long day of work or a tough workout is a great alternative to going to a sauna. Apart from relaxing, steam showers can also be beneficial for clearing congested sinuses, promoting glowing skin, and improving circulation. Having a steam shower in your home will enhance your health and wellbeing.

You will need to purchase a steam shower generator if you wish to install a steam shower at home. The steam generator is the device that heats water to the right temperature to create steam. Your shower system then emits the steam through your steam head, which almost instantly fills your shower with warm, relaxing steam. So when you’re looking for a steam generator, wouldn’t it be best to pick the best one available? There are a number of important factors to consider before purchasing a steam shower generator for your home. Depending on the size of your steam shower, you will require a different size steam shower generator.


Steam Generators Buying Guide 

When purchasing a steam shower generator, you should think like a plumber. There are several factors you should consider:

  • Certifications, and safety checks, among others.
  • Materials used, craftsmanship quality, and product warranty.

Secondary concerns include:

  • Water consumption.
  • Noise levels.
  • Control panel usability.
  • Range of temperatures.
  • Ease of making adjustments in real-time.
  • Time required for it to heat up.
  • Amount of steam generated.

And how do you select a steam shower generator? First, decide which feature is important to you. Aromatherapy or surround sound may be important to you. Some people look for high maximum temperatures, while others prefer low energy consumption.

Therefore, selecting the best steam shower generator varies from buyer to buyer. The layout and size of your shower will affect which steam shower generator option you choose. For instance, if your shower area is large, a steam shower generator with a higher power rating and capability to cover larger areas would be best.


Dimensions of the Shower Room

It is essential to know your shower room volume before choosing a steam shower generator since most product descriptions include information about the unit’s performance. 

For a large shower room, a generator would need to produce more steam in order to cover the entire area. Thus, the best steam generator to use for a large shower room is one that outputs a large volume of steam.



Another important factor to consider when buying a steam shower generator is its dimensions. The generator must, after all, fit inside your shower space! Steam shower generators typically have the following sizes: 15 inches x 6 inches x 15.5 inches. There are, however, both smaller and larger options available for all tastes. 



When choosing the suitable option, be sure to consider its weight. It is generally easier to install lighter and smaller steam shower generators than heavier and larger steam shower generators.


Power Consumption

Steam shower generator buyers often worry about power consumption. Even so, this concern is not well-founded since steam showers are quite inexpensive, given their level of luxury. Among the most efficient and economically viable luxury shower items, steam shower generators largely depend on the homeowners’ existing standing charges for electricity and water. Yet, it is true that the amount of power consumed will depend on the shower room size. A steam generator’s power requirement increases with the amount of steam it is able to produce.


Starting Time

It is also important to consider the process of starting each steam shower generator. As steam is a heat-producing substance, each steam shower generator must be allowed to warm up before it can efficiently produce steam. On average, it seems like a warm-up takes about ten minutes. However, it may vary depending on which steam shower generator you use. It will take longer for larger steam shower generators with larger dimensions and capacity to heat up, while more powerful steam shower generators will heat up more quickly.


Automatic Drainage

Steam shower generators with automatic drainage are excellent features to look for. It’s the one that no one ever realizes they need! With automatic drainage, any surplus water within the steam shower generator is automatically drained. By using this feature, you not only eliminate the need for any cleanup but also prevent any buildup of bacteria or minerals in your system. It also prolongs the life of your unit.


Control Panel

Your steam shower control panel is the key to having the best experience, so you will want one with an intuitive, easy-to-use control panel. Control panels often come with a timer as an essential feature. You can use it to know how long you have been in the shower. Steam shower generators may even automatically turn off the steam once the timer goes off, providing a hassle-free and convenient experience.


Noise level

Noise is another factor buyers should consider. In case you have roommates or young kids, you won’t want a steam shower generator that is extremely noisy while in use, since you run the risk of waking them up or disturbing them. Manufacturers of steam shower generators are aware of this and have designed their products to be as quiet as possible.



To install the steam shower generator, you will have to connect it to some cables in order to provide the steam shower generator with power, water, etc. Make sure the cables are included with your purchase. Otherwise, you should see if the manufacturer can suggest a suitable cable.

You should also make sure not to exceed the range of the cable when installing the steam shower generator. Such practices are potentially dangerous and could lead to future malfunctions.



It would be wise if you also thought about the warranty when buying a steam shower generator. When you purchase a “luxury” item, you want to make sure that it will work for many years to come. Buy a steam shower generator that comes with a warranty if you want to be sure you’re getting a quality product. There are different warranty types available – generally, there are options ranging from 6 months to 3 years. It’s always a smart choice to find a steam shower generator that has a warranty, regardless of its duration!

FAQs about Steam Generators

What are the two main types of steam generators or boilers?

Large pressure tanks called steam boilers use intricate fuel systems to heat water to the boiling point. Fire-tube and water-tube boilers are the two primary categories of steam boilers.

What is the difference between steam boiler and steam generator?

Even when the burner is turned off, flash steam can come out of a steam boiler to meet system needs. This is because steam boilers have a higher water content per output than steam generators.

How long do steam generators last?

Steam boilers typically last 20 to 30 years, provided regular maintenance and care procedures are followed. The three most crucial factors to examine when thinking about replacing a steam boiler are safety, economics, and requirement changes.

Are new steam boilers more efficient?

Modern boilers may attain efficiencies as high as the mid-nineties, turning virtually all the fuel into usable heat for the residence, compared to earlier boilers’ range of 56% to 70%.

Are there high efficiency steam boilers?

Although steam boilers are less efficient by nature because they run at greater temperatures than hot water boilers, high-efficiency versions of all kinds of furnaces and boilers are now readily accessible.
