freeze damage is when water freezes and broadens within spa pipelines or spa equipment, like your filter, pump or heating system.
Water expands about 10% when it freezes. For pipelines or equipment that have a little quantity of water within, for example a pipe that is less than half filled with water, unused space inside the pipe enables some ice growth.
When pipes, pumps or filters are over half complete of water, there is little space for growth, and even extremely thick products can rupture from the ice pressure inside.
Today’s lesson centers on ways to avoid freeze damage in a spa or hot tub, which can be a complicated and pricey spa repair work, and sometimes, could ‘total’ the spa, with repair work expenses of thousands of dollars.
There are 3 ways to prevent freeze damage in a spa or hot tub
1. Winterize the Spa
We do not recommend that you winterize your spa, unless you are sure that it won’t be used for at least 3 months, or it can not be maintained (at a vacation house, for example).
Winterizing the spa is a procedure that takes a few hours, to drain all of the water from the spa, and utilize air to ‘blow the lines’, to require water from the pipelines, hoses and equipment.
We did a short article on How to Winterize a Spa, if you are considering winterizing the spa. It’s simple, however if you desire guarantees of a proper winterization, most spa service business offer this service.
2. Usage Freeze Protection
Modern medspas packs will have a freeze security mode on the spa that will turn on the flow pump when temperatures get near freezing. If you don’t see this available in your control alternatives for the spa, you may not have freeze security.
Freeze security works with an air temperature sensor that interacts with a controller, wired into the pump power circuit. Freeze security is standard equipment on all our Digital, Flex-Fit and Balboa spa loads, which is the most basic way of adding freeze security for older spas with air activated spa packs.
For aid including freeze security to your spa, feel complimentary to call our spa techs with some info about your spa.
3. Run the Pump
As long as water is moving through the pipes– all of the pipes, the water will not freeze. Open all of your jets, if your spa has the capability to separate banks of jets. Low speed can be used, as long as all pipelines are made use of.
The water need not be hot, or even heated at all–. As long as it’s moving through all the pipelines and equipment when temperatures are listed below 32 degrees. The heat from the spa pump, under a closed skirt, is also valuable to heat up the devices. Naturally, a spa cover need to be used during winter to avoid ice forming on the spa surface.
Throughout winter, it might be smart 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 give 24 hours of security
• Keeping a tight fitting spa cover in place and protect
• Spa insulation– the more there is, the more protection you have
• Hang a 100 watt shop 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 perhaps you spot some freeze damage currently, the devices needs to be defrosted out. If there are broken pipelines, using electrical area heating systems might be unsafe, under the skirt.
If you have an outdoor camping tent large 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 utilized whenever we ‘d get a ‘frozen spa’ call. We utilized a little kerosene heater once the tent was established over the spa, and monitored it carefully. If there was freeze damage, (and there generally was), we would drain it entirely, make the repair and fill it back up.
Including warm water to the spa is another old trick. With a little adapter, a garden hose pipe can be connected to most sink faucets, to bring hot water to the spa, to raise the water temperature for a faster thaw. Sometimes, you can carefully wet frozen pipes with warm water– just do not spray any motors, electronic devices or controls.
SPA POWER FAILURE!
If your power stops working throughout winter season, keep in mind that a heated spa with a good fitting spa cover has enough warmth to prevent freeze damage for 24 hours approximately, longer if it’s effectively insulated.
To maintain some heat under the spa skirt throughout a power failure, you might hang a 100 watt store light in an area close to the spa pack. In some scenarios, a small area heating unit might be safe to use likewise, inside the spa cabinet, in a dry place, till power is brought back.
