Managing Hot Tub Running Costs: 4 Ways to Save

Owning a hot tub is a fantastic way to relax, unwind, and enjoy quality time with family and friends. However, like any luxury, it comes with ongoing expenses. From electricity usage to maintenance, the daily running of a hot tub can soon add up if not carefully managed.  

The good news? With a few smart decisions, you can keep your running costs under control while still making the most of your spa experience. 

Understanding Running Costs

Before you can reduce your hot tub expenses, it’s important to understand what contributes to them. Typical running costs include: 

  1. Electricity – Heating the water and running pumps are the biggest energy drains. Depending on today’s usage and energy tariffs, this can cost somewhere between £1 and £2 per day.
  2. Water – While not a major expense, you will need to drain and refill your tub every few months to keep it clean an in the best working order. 
  3. Chemicals – To keep the water clean and safe, you'll need regular supplies of sanitisers, pH balancers, and other treatment chemicals.
  4. Maintenance and Repairs – Occasional servicing, filter replacements, or part repairs can also add to your annual costs.

Having a clear picture of these elements allows you to identify where savings can be made. 

Choose an Energy-Efficient Hot Tub

If you’re buying a new hot tub or considering an upgrade, choosing an energy-efficient model is crucial. Modern hot tubs come with better insulation, more efficient pumps, and smarter heating systems, all of which help reduce energy consumption. 

Look for models that offer: 

  • Energy-efficient circulation pumps 
  • Programmable controls or timers 
  • Certification for energy performance where applicable

Though the upfront cost may be higher, these features can significantly reduce your monthly bills over time. 

Use a Good Quality Cover

One of the simplest and most cost-effective ways to cut down on heat loss is by using a high-quality hot tub cover. Heat rises, and without a proper cover, much of it escapes meaning your heater must work harder (and cost more to run). 

Choose a cover that:

  • Fits tightly and seals properly 
  • Contains dense foam insulation 
  • Includes a moisture barrier to prevent water absorption

Regularly check your cover for signs of wear or sagging. A waterlogged or damaged cover won’t provide adequate insulation and should be replaced when necessary. 

Carry Out Regular Maintenance

Ah, maintenance the necessary chore! Keeping your hot tub well-maintained ensures it runs efficiently and extends its lifespan. Neglecting maintenance can lead to blockages, imbalanced water, and overworked components all of which increase energy use and costs. 

Key maintenance: 

  • Cleaning or replacing filters as per the manufacturer’s guidance 
  • Monitoring and adjusting water chemistry regularly 
  • Checking pumps and jets for smooth operation 
  • Draining and refilling the tub every 3 to 4 months

Consistent upkeep ensures your system doesn’t have to work harder than necessary, keeping your costs down. 

Final Thoughts

Managing your hot tub’s running costs doesn't have to be difficult. By taking simple, proactive steps like using an energy-efficient tub, investing in a quality cover, and staying on top of maintenance you can enjoy all the benefits of your hot tub without the stress of spiralling bills. A little effort goes a long way when it comes to long-term savings.
