Hot Tubs Heaters
At Easy Spa Parts we carry every Dimension One Spas heater still available. Starting in the 1980’s, D1 heaters often used a replaceable heating element similar to a water heater design but about 12” long. With the advent of the Crystal Pure Ozone System, Dimension One introduced a large heating coil that efficiently warmed the water at low wattage. By 1997 many Dimension One hot tub heaters began using a Laing heater. This 01781-27 low flow heater utilizes a small circulation pump to silently move water through the heater tube. The Dimension One @Home series currently uses the traditional 01562-08 2” flow through heater which requires the main jet pump, operating low speed, to heat the spa water.
Quality Hot Tub Heaters—How Long Should It Take to Heat My Spa?
If you’ve never owned a hot tub, you probably have a few questions about how it works, and what to expect. One of the most popular questions has to do with heat times. In other words, how long should it take for your hot tub heater to heat the water in your spa? Of course the answer to this question varies based on where you live, and the weather. If you live in a warm climate, it should take far less time to heat your spa than if you live up north where temperatures are cold. All things considered, your spa water should warm at a rate of approximately 3 to 5 degrees per hour.
Basically, there are three factors involved in hot tub heat time:
- Ambient temperature.
- Whether or not you use a hot tub cover.
- Age and performance of hot tub components.
Ambient temperature has to do with the air temperature around the hot tub. For example, if it’s 80 degrees outside and your hot tub is on the back deck, it will heat relatively fast. By comparison, if it’s in the middle of winter and the temperature outside is 36 degrees, reaching an optimal temperature will take longer.
Here’s the good news: using a spa cover can considerably reduce heat time. The right cover serves to insulate the tub, or prevent heat from escaping. When it’s time to heat up, the hot tub will reach a high temperature more efficiently.
Finally, keeping your spa in excellent working order ensures that your hot tub heaters, pumps, and other important components work as they should. Over time, all components will wear out. However, modern spa heaters can be extremely efficient when cared for properly. In addition to spa heaters, be sure to check your hot tub cover regularly to identify any rips or tears in the vinyl, which could make heating the spa less efficient.
Keep filters clean and monitor circulation pumps on a regular basis too, for water and heat to flow freely throughout the spa. Maintenance is key—and the easiest way to make sure your hot tub heaters continue to provide you with warm, relaxing water when you need it most.
Spa Heaters and Energy Use
There’s nothing quite like slipping into a piping hot spa. For relieving aches and pains, loosening a tight neck or stiff shoulders, a soothing few minutes enveloped by sustained heat is divine. But what about energy use? Are hot tubs efficient, and is there any way to keep energy use to a minimum while enjoying regular hydrotherapy?
Most hot tubs rely on electric or natural gas spa heaters to warm the water. With efficiency in mind, quality hot tub brands have started manufacturing tubs that are equipped with energy efficient components. Energy efficient spa heaters, pumps, even LED lighting help control cost, along with quality insulation in both the shell and the hot tub cover. Effective insulation can greatly improve the efficiency of the hot tub.
Dimension One Spa Heater
If your D1 hot tub heater is not warming the water your first thought might be to buy a new heater. Think again. Better yet, call the expert technicians at Easy Spa Parts for help diagnosing your spa. Every UL certified hot tub requires a 01710-131 flow switch or 01515-04 pressure switch to insure there is adequate water flow through the heater, before allowing the water to warm. All other facets of the D-1 hot tub heater system could be operating correctly but if the flow switch is defective you’ll see the typical “Low Flow” error indicated on the main control panel. Watch our informative low flow error video on troubleshooting for more information.
If your D-1 heater requires a Laing 01512-320E low flow pump, a defective or air locked unit can also cause a low flow error. Again, watch our low flow video or call us for troubleshooting help here too. If all flow systems appear to be operating properly, you might need to use a small compressor to clear the heater / ozone lines to improve flow. Follow the steps in this instruction sheet to see if it helps.
Some D-1 spas with relatively new 01782-27 or 01781-27NS heaters may have tripped the TCO safety switch. Call us for an instruction sheet showing this procedure. All the steps above, and others, are offered so you understand that a Dimension One Spa that’s not heating does not necessarily mean you need to buy a new heater.
Spa Heater FAQs
My spa is not heating. Do I need a new hot tub heater?
Maybe not. The most common reason for a spa to stop heating is a “Flow Error”. Call us before buying a spa heater and we can help troubleshoot the root cause of the problem.
Are all spa heaters the same?
We offer only the factory designed heater and all other spa parts for your Dimension One Spa. Heaters vary by size, shape and electrical requirements. Get the right heater for your spa – call the experts at Easy Spa Parts.
Can poor water quality damage a heater?
Yes. Over time, water that has a pH reading that is too high or low can attack the heater element or tube and cause it to trip the gfi. Titanium heating elements resist this damage better than cheaper, incaloy elements. We use titanium elements whenever they are available.
Can I install new hot tub heater myself?
Installing new hot tub heaters can be a little tricky, so call us for advice about doing it yourself. Easy Spa Parts has step-by-step instructions for some heaters and can walk you through the task with other units.
