14 best spa heaters

Spa heaters are essential components of hot tubs and spas, designed to heat the water to a comfortable and therapeutic temperature. They play a crucial role in maintaining the overall enjoyment and functionality of these aquatic relaxation systems. Here's what you should know about spa heaters:

  1. Heating Method: Spa heaters typically use one of three main heating methods: electric heaters, gas heaters, or heat pumps. The choice of heating method depends on factors such as energy efficiency, cost, and available resources.

  2. Electric Heaters: Electric spa heaters are powered by electricity and are known for their ease of installation and relatively lower upfront cost. They are ideal for smaller hot tubs and spas.

  3. Gas Heaters: Gas-powered spa heaters use either natural gas or propane to heat the water. They are capable of quickly raising the water temperature and are suitable for larger spas or hot tubs. Gas heaters are often favored for their efficiency in colder climates.

  4. Heat Pumps: Heat pumps are energy-efficient spa heating options that transfer heat from the air or surrounding environment to the water. They are environmentally friendly and cost-effective over the long term, although they may have a higher initial cost.

  5. Temperature Control: Spa heaters come with temperature control features that allow users to set and maintain the desired water temperature. Many modern heaters are equipped with digital thermostats for precise control.

  6. Size and Capacity: The size and capacity of a spa heater should match the volume of water in the hot tub or spa.A heater that is too small may struggle to maintain the desired temperature in larger spas.

  7. Installation and Maintenance: Proper installation and regular maintenance are essential to ensure the longevity and efficient operation of spa heaters. Maintenance tasks may include cleaning, inspecting for leaks, and addressing any electrical or gas-related issues.

  8. Safety Features: Spa heaters are equipped with safety features such as pressure switches, high-limit switches, and safety sensors to prevent overheating and ensure user safety.

  9. Energy Efficiency: Energy-efficient spa heaters can help reduce operating costs. Look for models with high energy efficiency ratings and features like timers to optimize energy use.

  10. Compatibility: When replacing or upgrading a spa heater, it's important to ensure compatibility with the existing plumbing and electrical systems. Consultation with a professional technician may be necessary.

  11. Warranty: Spa heaters often come with warranties that cover various components. Be sure to understand the warranty terms and conditions before purchasing.

In summary, spa heaters are crucial components in hot tubs and spas, allowing users to enjoy warm and relaxing water experiences. They come in different types, sizes, and heating methods, and selecting the right spa heater depends on factors such as the size of the spa, energy efficiency goals, and available resources. Proper installation and maintenance are essential to ensure their longevity and safe operation.

User questions & answers

Question: I have 18’ above ground pool, living in NJ this heater will work for me
Answer: I have it on a 15’ pool indoors in a heated room at 80° it takes 2 hours to heat 1°. I think that you need a much bigger heater, especially if you are thinking for the spring and fall months.
Question: my tub is 330 gallons, how long would it take to heat
Answer: Hello Lawrence. The Smart SPA 5.5 will heat a 330 gallon tub by 15F in about 180 minutes.GadgetsGo is an Authorized Ecosmart Dealer.Kind Regards,Ross GadgetsGo
Question: What is the temperature setting range on the digital display
Answer: Hello Dave. The temperature setting range on the digital display is 80F -104F (26C - 40C) in 1 degree intervals. GadgetsGo is one of the first Authorized Ecosmart Dealers, since 2009. Feel free to ask us any other questions. Kind Regards, John M. GadgetsGo
Question: I want to replace a propane water heater with this electric spa heater, is this possible? Please advise
Answer: Hello Mary Ann, This unit heats a spa with 700 gallons of water by 20°F in about 6 hours (and a proportionately lower temperature rise with a more gallons, and higher temp. rise with less gallons). All tankless water heaters operate on the same principle. The SPA 5.5 requires a 30 amp double pole breaker and 220V, hard wired to your junction box or electrical panel. GadgetsGo is one of the first Authorized Ecosmart Dealers, since 2009. Kind Regards, John M. GadgetsGo This heater requires one 40 amp double pole breaker. If it will not produce the desired flow rate and temperature rise to get to 105°F, then choose another model with more kW and amps, and ensure that you can supply it with the required electrical capacity. For a complete explanation of how to choose a tankless water heater, check out our blog post at blog.gadgetsgo.com.

Hot Springs Heater Relay Board 77119 (Formerly 74618) IQ 2020 Watkins

Hot Spring

Based on 203 reviews Check latest price

Product description

This is an upgraded IQ 2020 Heater Relay Board with jumpers & shortened screws for the front cover of the IQ2020. When part was upgraded, it went from three relays to two.

Replaces the 74618 as of 9-10-2013

What is included: NewUpgraded IQ 2020 Heater Relay Board w/ Jumpers & Shortened Screws for the front cover of the IQ2020

Description: New(New as of 9-10-2013) This IQ2020 Heater Relay Circuit Board is the newest revision for the 2001-2009.5 IQ2020 Control Box. It's upgraded design provides a more efficient method of connecting the heater's power cord to this board therefore reducing fatigue on the two "beefed up"relays. The black wire from the heater's power cord now connects into the H1 position on the large gray terminal block. The heater's white wire (neutral) connects onto its own separate gray terminal block labeled H2. This will reduce stress on the relays and increase their lifespan due to better transfer of voltage. The ground wire connection remains the same. The incoming power wires and the black & white wire from the heater are inserted into the gray terminal blocks round holes by prying the gate open using a small screwdriver. This upgraded circuit board replaces the 1st, 2nd & 3rd generation boards in the IQ 2020 Control Box found in all 2001-2009.5 Hot Spring, 2001-2009 Tiger River and 2008-2009 Limelight spa models.

Symptoms this part has failed:

No power going to the heater even though the red HTR ON L.E.D. light is lit inside the IQ2020 control box.

The heater board is charred on the front and/or the backside.

Note: In older control boxes, you may encounter that a chip on this new heater relay board prevents the metal guard from seating properly and it may need to be trimmed. Visit backyardplus to watch video or download instructions.

Note #2: This circuit board works in all countries

User questions & answers

Question: I have an apollo spa model ap9696s. which heating element works for it? thanks in advance
Answer: Measure length of your tube and research wattage that originally came with tub.
Question: I have a Royal Spa majesty tub. Will this one work for my tub
Answer: It most likely will fit if your hot tub uses 240 volts. Get it from Amazon, and when you have it, compare it side by side with your old one. Its an easy job to remove the old one from your spa. If its different, you can always return it.
Question: Is there a simple way to determine if my heater is no good? Measure resistance
Answer: If it is a 5500 watt heater and 240 volt, Ohms should be about 10 - 11 ohm. Math is volts squared divided by watts = ohms
Question: Does it fit Gecko heater 4kw s15” flow thru 2.25” dia
Answer: No it does not
