How Much Does a Water Distillation System Cost in 2024?

Average Cost:

$2,000 - $6,000

Water distillation systems range in cost based on type, size, and features of each system. On average, countertop distillers range from $100 to $600, while whole-house distillation systems typically cost between $2,000 and $6,000. Commercial systems can be much more expensive, starting at $5,000 and reaching upwards of $20,000 for larger, customized setups. In this article, we will explore factors influencing the cost, as well as the pros, cons, and maintenance considerations to help you determine the best option for your needs.

Water Distillation: Types, Costs & Benefits

Water distillation systems boil water to produce steam, which is then condensed back into a liquid form. The result is that contaminants such as bacteria, heavy metals and chemicals are removed from the final product. It’s considered a very reliable purification method.

The cost of a water distillation system varies based on the type, size, brand and additional features. In general, countertop distillers cost less and are ideal for small households, while a whole-home system will cost much more and require a more intensive installation process.

In this guide, we’ll break down the different types of water distillation systems and the factors that affect their cost.

What Is a Water Distillation System?

A water distillation system operates by heating water to its boiling point, creating steam. The steam rises, leaving contaminants such as salts, minerals, chemicals, bacteria and other impurities behind. This steam is then captured and cooled, returning it to liquid form and leaving purified water behind. Other water filtration methods such as reverse osmosis often leave some contaminants behind.

Water distillation is often used in household settings to purify drinking water, but it’s also used on larger scales for commercial properties such as laboratories, hospitals, and other industrial applications looking to ensure the highest levels of purity for their operations.

Types of Water Distillation Systems

There are several types of systems designed for different needs, and each ranges in cost.

Countertop Distillers

Countertop water distillers are smaller, portable units that are designed for personal use. These systems typically have a lower water capacity between one to four gallons and are ideal for smaller households and individuals who want purified water for drinking and cooking. Countertop distillers are affordable, easy to use, and require minimal setup, meaning they’re also the least expensive type on the list.

Whole-House Distillation Systems

Whole-house systems are larger units that treat all of the water entering a home. These systems are ideal for households that want purified water for drinking, cooking, bathing, and cleaning. Whole-house distillers have a much higher capacity than countertop models and are typically installed as a point-of-entry system. Installation can be more complex and may require professional help. These systems are much more expensive than countertop distillers.

Commercial and Industrial Distillation Systems

Industrial distillation systems are available for commercial usage. These systems are typically designed to handle much higher volumes of water than whole-home systems and are often customized to meet the specific needs of businesses or laboratories. The cost of commercial and industrial systems can vary widely, depending on the size and complexity of the setup but are the most expensive type on the market.

Factors That Affect Water Distillation System Costs

Several factors influence the price of a water distillation system, including:

  • System Size and Capacity: Larger systems with higher capacities, such as whole-house distillers, tend to be more expensive due to their increased power and complexity.
  • Brand and Quality: Premium brands often charge more for their systems, but these also come with improved durability, advanced features, and longer warranties.
  • Additional Features: Some systems include extra features such as digital controls, automatic cleaning, and built-in storage tanks, all of which can increase the price.
  • Installation Requirements: While countertop systems can be installed easily by the homeowner, whole-house systems often require professional installation, adding to the overall cost.

How Much Does a Water Distillation System Cost?

The cost of water distillation systems ranges based on top. Countertop distillers typically range from $100 to $600. Whole-house systems generally cost between $2,000 and $6,000, including installation. Commercial and industrial systems start around $5,000 but can often exceed $20,000.

Many manufacturers offer financing options to help make the upfront cost more manageable. Additionally, seasonal promotions and discounts are often available, especially during sales events. Some suppliers may offer discounts if you bundle your distillation system with other water treatment solutions, such as reverse osmosis filters or water softeners.

Larger, whole-home systems and commercial systems often require professional installation, which is a separate, added cost. In addition, these systems should be regularly serviced, which is also an added expense.

Professional installation for whole-house water distillation systems ranges from $500 to $2,000, depending on the complexity of the plumbing and the size of your home.

Routine maintenance includes cleaning to remove scale buildup where hard water is a factor. Filters should also be replaced depending on usage. This kind of maintenance typically costs between $50 to $300 per year for professional house calls.

Pros and Cons of Investing in a Water Distillation System

As with any water treatment system, there are many benefits and considerations when it comes to using a water distillation system. Understanding both the advantages and limitations can help you decide if a water distillation system is the right choice for your home.

  • Pros

    • Effective Purification
    • Long-Term Savings
    • Sustainable
  • Cons

    • Higher Upfront Cost
    • Energy Usage
    • Maintenance

Pros

  • Effective Purification: Distillation removes a wide range of contaminants, including heavy metals, bacteria, and chemicals.
  • Long-Term Savings: With a water distillation system, you can reduce or eliminate the need for bottled water, which saves money over time.
  • Sustainable: Using a distillation system reduces the environmental impact associated with bottled water production and disposal.

Cons

  • Higher Upfront Cost: Water distillation systems, especially whole-home systems, cost much more than other types of water filtration solutions.
  • Energy Usage: Distillation is a process requiring energy to heat water, which can increase utility costs.
  • Maintenance: Purified water requires a system that operates smoothly, and water distillation systems need regular, professional maintenance for optimal performance.

Is a Water Distillation System Right for You?

Homeowners concerned about the quality of their water supply will benefit from the improved quality and peace of mind that comes with installing a home water distillation system. When deciding whether to invest in a water distillation system, consider factors such as your household water needs, budget, and the quality of the local water supply.

For households with limited space or smaller water consumption needs, a countertop distiller might be sufficient. Larger households or those with specific purification needs may benefit more from a whole-house system.
