Hot Tub Costs for Electricity

A hot tub requires electricity to power its heating system, jets, and other components. The cost of electricity will depend on the type of hot tub, its size, and how often it is used.

The initial hot tub cost varies depending on its size, features, and brand. However, the cost of owning a hot tub does not stop at the purchase price. In addition to chemical costs, hot tub running costs include electricity expenses.

On average, hot tub owners can expect to spend $30-$50 monthly on electricity. This figure may vary depending on the frequency and duration of hot tub usage, the efficiency of the hot tub's heating system, and the local electricity rates.

Here are our tips on reducing the hot tub electricity costs:

1. Invest in an Energy-efficient Hot Tub.

Energy-efficient hot tubs use less energy while maintaining the same level of heating performance. They are equipped with:

  • Advanced insulation
  • Efficient heating systems
  • Smart controls (These allow you to set and monitor the temperature of the water)

Energy-efficient hot tubs can save you money in the long run by reducing your monthly electricity bills.

2. Provide Proper Insulation for Reducing Hot Tub Running Costs.

Heat loss is one of the primary reasons why hot tubs use a lot of electricity.

Ensuring that your hot tub is properly insulated can significantly reduce heat loss and, as a result, reduce your electricity bill.

3. Regulate the Temperature of the Water.

Turning down the temperature by just a few degrees can save you money on your electricity bill. For example, lowering the temperature from 104°F to 100°F can reduce hot tub running costs by up to 30%.

Water Costs

When it comes to hot tub ownership, one cost that is often overlooked is the cost of water. Hot tubs require a significant amount of water to fill, and depending on the size of your hot tub, the cost to fill it can vary.

The frequency with which you need to refill your hot tub depends on several factors, including the size of your hot tub, how often it's used, and how well you maintain the water quality. It's recommended to drain and refill your hot tub every three to four months for optimal water quality, even if you use a cover and maintain the water regularly.

If you have a standard-size hot tub that holds around 400-500 gallons of water, it can cost you around $2-$4 to refill it, based on the average cost of water at $0.004 per gallon. If you have a bigger hot tub that holds 700-800 gallons of water, refilling it can cost around $5-$8. Remember that this cost can vary depending on your location and water provider, so it's always a good idea to check with your local utility company for exact pricing.

Repair and Replacement Costs

Hot tubs require regular maintenance to keep them in good condition, but even with proper maintenance, they may still require repairs or replacement parts over time.

Here's what you need to know about hot tub repair and replacement costs, especially for new and older ones.

New Hot Tub

If you've recently purchased a new hot tub, you can expect to spend less on repair and replacement costs for the first few years. New hot tubs come with warranties that cover the cost of repairs or replacements for defects in materials or workmanship. It's still essential to read the terms and conditions of the warranty to understand what it covers and for how long.

Older Hot Tub

If you own an older hot tub, the repair and replacement costs may be higher, especially if you haven't kept up with regular maintenance. Common issues with older hot tubs include:

  • Leaks
  • Pump failures
  • Control panel malfunctions

Repairing or replacing these parts can be expensive, depending on the severity of the issue and the availability of replacement parts.

Repair Costs

The cost of repairing a hot tub varies depending on the type of repair needed and the severity of the issue. Minor repairs like replacing a filter or a jet, can cost as little as $50-$100. More significant repairs, such as fixing a pump or a heater, can cost $500-$1,500 or more.

It's essential to address issues as soon as they arise to prevent them from becoming more severe and more expensive to fix.

Replacement Costs

If your hot tub requires replacement parts or components, the cost can vary significantly depending on the make and model of the hot tub. For example, replacing a hot tub cover can cost between $200-$500, while replacing a pump or a heater can cost $1,000 or more. In some cases, replacing the entire hot tub may be more cost-effective than repairing or replacing individual parts.

Hot Tub Maintenance Cost

Regular maintenance is essential to keep a hot tub in good working condition. The spa maintenance cost will depend on the frequency of servicing and the system's complexity. The average maintenance cost for a hot tub is around $300 to $500 per year. Here is what you need to cover:

Cleaning the Filters

If you choose to clean the filters yourself, the cost is minimal. All you need is a garden hose, a bucket, and a filter cleaning solution, typically costing around $10-$20.

The cost can be higher if you prefer to hire a professional to clean your hot tub filters. Professional hot tub maintenance companies may charge $50-$100 or more to clean your hot tub filters, depending on the size and type of your hot tub.

We recommend cleaning your hot tub filters at least once a month, depending on how often you use your hot tub. If you use your hot tub frequently, you may need to clean the filters more often. A good rule of thumb is to inspect the filters regularly and clean them when you notice they're dirty or clogged with debris.

Servicing the Heating System

Hot tub heating systems require regular maintenance and occasional repairs to keep them working correctly. The cost of servicing a hot tub heating system can vary depending on the type and severity of the issue.

Minor repairs likereplacing a faulty thermostat or heating element, may cost between $100-$200. More significant repairs, such as replacing the entire heating system, can cost upwards of $1,000.

A new hot tub cover can range from $200 to $500, depending on the size and type of cover you need. It's important to replace a damaged or worn-out hot tub cover as soon as possible to prevent heat loss and maintain the system's energy efficiency.
