Eco-Friendly Spa Ownership: Reducing Energy Use and Water Waste
Owning a spa pool doesn’t have to mean high utility bills or a heavy environmental footprint. With a few smart habits and practical upgrades, you can enjoy the comfort and health benefits of your spa while minimising energy use and conserving water. This guide will help you run your spa more efficiently, lower your impact, and save money in the process.
1. Use a High-Quality, Insulated Spa Cover
One of the easiest ways to reduce heat loss is to invest in a well-insulated, properly fitted spa cover. A good cover traps heat, prevents evaporation, and keeps debris out.
Close it tightly when not in use
Replace damaged or waterlogged covers to maintain efficiency
Clean and treat it regularly to extend its lifespan
You can also add a thermal spa blanket that floats on the water’s surface for extra insulation.
2. Lower the Default Temperature
Every degree counts. Setting your spa to 37°C instead of 39°C can make a noticeable difference in energy use without sacrificing comfort. If you don’t use the spa daily, consider:
Using an economy or sleep mode
Reducing the temperature between uses
Scheduling heating cycles for your typical soak times
Keeping the water warm, rather than reheating from cold, is often more efficient in the long run.
3. Maintain Your Spa Regularly
A well-maintained spa runs more efficiently and uses fewer resources. Clean filters ensure smooth circulation, which reduces strain on pumps and heaters. To optimise efficiency:
Rinse filters every 1 to 2 weeks
Deep-clean or replace them every 3 to 6 months
Check for blockages or worn components that affect flow
Healthy water also means fewer chemical adjustments and less frequent draining.
4. Choose an Energy-Efficient Spa Model
Not all spas are created equal. Trueform spas are built in New Zealand with durable, fully insulated acrylic shells that retain heat efficiently and stand up to local weather. Look for models that include:
Full foam or perimeter insulation
Programmable heating and filtration settings
Ozone or UV sanitising systems to reduce chemical use
If your spa is older, an upgrade may offer long-term savings.
5. Conserve Water Where Possible
Spa pools require water changes a few times per year, but that doesn’t mean you can’t reduce waste:
Keep water clean to extend its life
Cover the spa when not in use to reduce evaporation
Drain and refill only when water quality cannot be restored
Use leftover spa water for outdoor cleaning or garden watering, where appropriate and safe
Always follow local water guidelines and consider environmentally friendly cleaning products when draining.
6. Choose Sustainable Accessories and Products
Small choices add up. You can reduce your environmental impact by selecting:
Reusable spa-safe cups and trays instead of disposables
Biodegradable or low-toxicity water treatments
Solar-powered lighting and accessories for your spa area
Timber decking from certified sustainable sources
An eco-friendly spa experience includes the environment around it, not just the water inside.
Final Thoughts
Making your spa more eco-friendly doesn’t require major sacrifices. With good insulation, thoughtful temperature control, regular maintenance, and sustainable habits, you can reduce your environmental footprint while still enjoying all the benefits your spa has to offer. It’s better for your budget, and better for the planet.
