>>> In honor of our fragile island home, 3rd rock from the sun – here are 3 ways to make your hot tub more eco-friendly this Earth Day – April 22! Saving Energy with improved insulation, Reducing Chemicals with alternative sanitizers and Saving Water by improving your spa filtration. Make your hot tub more eco-friendly >>>
Save Energy: Improve Insulation
Spas and spa covers are made for mild, moderate and severe winter climates. Spas and hot tubs that are not as well insulated as they could be, around the sides and on top, take more energy to maintain hot water and overcome radiant heat loss. This becomes more pronounced during very low temperatures and high winds. Fortunately, there are some things you can do to add more R-value to a poorly insulated spa. The Pink Panther brand (Dow-Corning) has lots of boards and thin bats that can be retrofitted into a spa cabinet to increase spa insulation.
On the topside, look at our Ultra or Works spa covers, for the best performance in a thermal spa cover. Replacing a thin, ill-fitting or waterlogged cover with a heavier weight 1.5 lb. or 2 lb. foam, in a 6-4″ taper, will really improve your spa or hot tub insulation, and save money on heat loss around the cover. For high winds, which can seep in under a spa cover and cool your spa, our High Wind Straps keep your spa from lifting up slightly during heavy winds. Finally, adding a floating foam spa blanket traps heat in the water where it belongs, and the added heat barrier helps reduce heat loss.
Reduce Chemicals: Secondary Sanitizers
When you reduce your use of chlorine and bromine, the Earth wins, because when you reduce your demand for chlorine or bromine, the supply (and production, and transport) slows down to compensate, as supply always adjusts to meet demand. Adding secondary sanitizers to your spa can cut your usage of chlorine or bromine by as much as half. I’m speaking about adding Minerals or Ozone purifiers to your spa, to remove the majority of the contaminants in the water, allowing you to use a much lower level of bromine or chlorine in the spa. Many people use Minerals and Ozone together, along with regular use of MPS shock, for a completely chlorine free hot tub.
Mineral sanitizers for spas are so easy to use, just drop the Nature2 Spa Stick or other brand mineral stick into the hole in your filter cartridge. Water passing by picks up the minerals, instantly purifying copper/silver ions. Connecting a spa ozonator like the Del Spa Eclipse is a piece of cake on any ozone ready spa or hot tub. For tubs without a Mazzei injector manifold, or other port to connect the ozone hose, you can install your own Mazzei injector into 3/4″ or 1″ water hose leading to a low-water ozone jet. It’s best to push ozone out of a dedicated ozone jet near the floor of the tub, but ozone can also be introduced through certain low wall jets.
Save Water: Improve Filtration
Your spa filter is the most important part of maintaining good water. And a good spa filter can be the difference between a water change every 3 months, or every 4 months, or even longer – if you have a really good spa filter. There are some things you can do to improve water filtration, for longer lasting water, and fewer chemicals needed to maintain water quality.
Firstly, many spa filter cartridges are available in the standard square footage size (25 sq. ft. for example), but also you can find the same size filter cartridge with more square footage (37.5 sq. ft. for example). Same dimensional size spa filter cartridge, but it has more pleats, for more square footage, or greater filter surface area. Secondly, many spa filter cartridges are also available in the blue Microban cartridge, which kills bacteria on contact, and it never wears off, although the cartridge itself will not last any longer than normal. Another thing you can do to really improve your spa filtration is to add a second spa filter. We’ve blogged about that before in more detail. Having two spa filters can drastically extend the time between water changes, and with a large spa filter, a spa could conceivably go an entire year between water changes! Finally, remember that filter cartridges should replaced every 12-24 months, depending on how big your filter is, and how often the spa is used. Regularly replacing your filter cartridge is the first step to maintaining water quality, and preventing excessive water changes.
Happy Earth Day!
