Gas Heating vs. Electric Heating

Question:

Is it better to go with a gas heater or an electric heater for a hot tub? -Nicole

Answer:

There are pros and cons to both types of heaters. Most portable spas come with built-in electric heaters, so in this case, the decision is made for you. In-ground spas are usually equipped with gas heaters. The advantage of gas is that it's generally cheaper and it also heats more rapidly than electric. The choice is yours.

Gas Spa Heaters

Question:

Are all hot tubs electric, or do they come gas heated as well? -Annonymous

Answer:

At one time, gas heaters were the norm when it came to heating your hot tub, but over the years, electric heaters have typically become standard equipment. Many companies have warmed back up to the idea of gas, and modern gas heaters are more energy efficient and will have lower operating costs than their electric counterparts. Today, a variety of propane and natural gas spa packs are available for both in-ground, and above-ground hot tubs. Many in-ground spas come with gas heaters and portable ones are often equipped for electric heating. Beware, however, that the cost of gas continues to rise at a greater rate than electricity. This is something to monitor and really the choice is yours in the end. For a helpful list of where to start shopping around, click on Hot Tubs to access our Hot Tubs Manufacturers section.

Water Not Heating

Question:

I recently purchased a used 145-gallon spa. It has been powered for 6-hours now and the temperature has only raised 10 degrees. I am a first time owner, but it seems like it's taking a long time to heat. Am I doing something wrong?

Answer:

If your water is circulating properly and your thermostat is turned up your spa should be heating. First, make sure your thermal cover is on. Heating will be much slower if the water comes in contact with the air temperature. Secondly, try cleaning or replacing your filter. Clogged filters will restrict your water flow forcing your pressure switch to shut down power to the heater. It takes hours to heat a cold spa, but should heat at approximately 1° to 1½°F per hour.

Low Jet Pressure

Question:

Lately, when we use our spa the pressure doesn't seem nearly as strong as it was last year. I've misplaced our manual. Can you help?

Answer:

Be sure you didn't overlook setting your spa to its highest speed. Your pump may need to be replaced if the voltage on the back of the motor reads correctly and the high speed still hasn't kicked in. You may have a circuit board or internal wiring problem. Be sure to inspect for breaks in the cord insulation and also for melted terminals. It's also possible these connections may need to be replaced. Have a look at our Home Spas section for more on home spas.

Faulty Switch

Question:

I installed a Jacuzzi® tub about 3 months ago. My problem is that the pump doesn't shut off when I push the button! I have to unplug it to cut off power. Could the problem be with the motor or is the switch faulty? -Bill

Answer:

The switch's function is to complete or break an electric circuit. To discover why your pump is still operating even after you've tried to turn it off, you must know what kind of circuit you're dealing with (series or parallel) to understand what type of switch it is. You could be facing anything from moisture problems and corrosion, to over-heated wires. The bottom line is that to troubleshoot effectively, you must know your system and basic electrical theory. My recommendation: avoid the risk, and subcontract a professional electrician. Click on Hot Tubs for a variety of related information, including Hot Tub Safety .
