freeze damage is when water freezes and expands inside of spa pipes or spa devices, like your filter, pump or heating system.
Water broadens about 10% when it freezes. For pipelines or devices that have a little quantity of water within, for circumstances a pipe that is less than half full of water, unused area inside the pipeline enables for some ice expansion.
When pipes, pumps or filters are over half loaded with water, there is little space for expansion, as well as extremely thick products can rupture from the ice pressure inside.
Today’s lesson centers on how to prevent freeze damage in a spa or hot tub, which can be a complicated and pricey spa repair, and sometimes, might ‘amount to’ the spa, with repair work expenses of thousands of dollars.
There are 3 methods to prevent freeze damage in a spa or hot tub
1. Winterize the Spa
We don’t advise that you winterize your spa, unless you make certain that it will not be utilized for a minimum of 3 months, or it can not be maintained (at a trip house, for instance).
Winterizing the spa is a process that takes a couple of hours, to drain all of the water from the spa, and utilize air to ‘blow the lines’, to force water from the pipelines, pipes and devices.
We did a post on How to Winterize a Spa, if you are considering winterizing the spa. It’s easy, but if you desire assurances of a proper winterization, most spa service business offer this service.
2. Usage Freeze Protection
Modern spas packs will have a freeze protection mode on the spa that will switch on the circulation pump when temps get close to freezing. If you do not see this offered in your control alternatives for the spa, you may not have freeze protection.
Freeze protection deals with an air temperature level sensor that interacts with a controller, wired into the pump power circuit. Freeze defense is standard devices on all of our Digital, Flex-Fit and Balboa spa loads, which is the easiest way of including freeze defense for older medspas with air activated spa packs.
For assistance including freeze protection to your spa, feel free to call our spa techs with some details about your spa.
3. Run the Pump
As long as water is moving through the pipelines– all the pipes, the water will not freeze. Open all your jets, if your spa has the ability to separate banks of jets. Low speed can be used, as long as all pipes are used.
The heat from the spa pump, under a closed skirt, is likewise useful to heat up the equipment. Of course, a spa cover must be utilized throughout winter season to avoid ice forming on the spa surface.
Throughout winter season, it might be a good idea to operate your pump 24 hours daily in cold northern areas, or set the time clock to switch on the pump for 10 minutes every half hour.
ALSO HELPFUL TO PREVENT FREEZE DAMAGE:
• Adding heat to your spa, a hot spa can provide 24 hours of defense
• Keeping a tight fitting spa cover in place and secure
• Spa insulation– the more there is, the more security you have
• Hang a 100 watt store light, under the skirt, next to the spa pack
Always cover the tub when you’re not using it, and check to be sure the cover is properly secured on the hot tub, because in this way you can avoid wasting energy which is good for you as well as for your pocket. If you are using a traditional rigid foam cover to do this the dealer you bought it from may have recommended to clean and condition it once a month with vinyl protector, because in this way you will avoid to let UV rays to damage it. What they don’t tell you is that the vinyl on the outside of your cover is rated by HOURS outdoors. 1500hrs to be precise. Cleaning it and rubbing it with vinyl treatment is just wasting your time and money while prolonging the inevitable. Which is why SpaCap.com Hot Tub Covers employ Sunbrella outdoor fabric which is rated by (wait for it) YEARS outdoors. In fact we have seen Sunbrella fabric still looking brand new after ten years outdoors. Nothing else comes close. That said, if you do need to clean your cover for some reason, use the solution just on the top of the cover and pay attention to not let the solution to pour into the water of the spa. It is better to take it off and clean also the underside of it with a mild cleaning solution. Rinse well and air dry.
If you discover a spa or hot tub that is strong frozen, and possibly you spot some freeze damage currently, the equipment requires to be thawed out. If there are split pipelines, utilizing electric area heating units could be hazardous, under the skirt.
If you have an outdoor camping tent big enough to place over the spa, you can thaw out a spa in a couple of hours. When I was servicing medspas in Colorado, we had a camping tent we used whenever we ‘d get a ‘frozen spa’ call.
Adding warm water to the spa is another old trick. With a small adapter, a garden hose can be attached to most sink faucets, to bring hot water to the spa, to raise the water temperature level for a much faster thaw. In some cases, you can gently damp frozen pipes with warm water– simply do not spray any motors, electronic devices or controls.
SPA POWER FAILURE!
If your power fails during winter season, keep in mind that a heated spa with an excellent fitting spa cover has enough heat to avoid freeze damage for 24 hours or so, longer if it’s effectively insulated.
To preserve some heat under the spa skirt during a power failure, you might hang a 100 watt store light in a place near to the spa pack. In some circumstances, a small space heating system might be safe to utilize also, inside the spa cabinet, in a dry location, up until power is restored.
