Spa Energy Efficiency Checklist

Spa Energy EfficiencyLet's face it, when it comes to buying luxury items such as a pool or spa, we know people don't always consider how much energy the new addition will use... Then once power bill comes in the mail, it hits them. Yikes.

We want to alleviate that shock to your wallet and give you a few things to think about before you make your purchase. This energy efficiency checklist should help you choose the right spa to fit your budget both before and long after it's been installed:

Cabinet Insulation

Did you know a hot tub loses a lot of energy through its walls? Let's walk through what we call our Good, Better, and Best insulation options:

  • Full-Foam Insulation (Good) — 1/2-pound-density urethane foam that fully insulates the space between the shell and the cabinet.
  • FiberCor Insulation (Better) — New material applied at a 2-pound density and 4 times denser than foam many hot tubs use.
  • Layered Insulation (Best) — Select models offer multiple layers of varying density foam to minimize voids and gaps for maximum efficiency of the hot tub.

Be mindful that it generally requires more energy to reheat the water than it does to keep it at a constant temperature. If you use your hot tub quite frequently, then try to maintain the water at your desired temperature to save energy.

Cover

A well insulated spa cover will also help you keep heat contained in the hot tub. If you're not sure what to look for, here are the three main components that indicate an effective cover:

  • Tight fitting
  • Dense foam core with a high R-value*
  • Feature additional material at the center to lock in the heat at the seam and edges

*R-value: a measure of the capacity of material, such as insulation, to impede heat flow, with increasing values that indicate a greater capacity.

Always remember these few tips, too:

  • Use a cover lifter to keep the cover off the ground
  • Clean and maintain your hot tub cover monthly
  • If you see that your cover is becoming dry, brittle, cracked, or sagging, look into a replacement

Circulation Pump

A dedicated circulation pump offers maximum energy efficiency while keeping noise at a minimum and helps circulate water continuously using only a small amount of energy (sometimes using as little energy as a 40-watt light bulb). Without this pump, the hot tub will rely on its jet pumps to circulate the water, which draws more power and noise than a circulation pump.

If you already have a hot tub with a circulation pump:

  • Set the pump timer to run for shorter periods during the day
  • Call your local electric company about the off-peak hours. We advise this because some companies offer lower rates during the off-peak hours

Want To Play On The Safe Side?

For additional ways to save energy, look for specific hot tub models that offer these energy efficient features:

  • Systems that allow heat generated by the spa's equipment to be recycled back into the water
  • Jets and power that are set a level you need so you don't consume too much energy
