Gas, Wood Or Electric Hot Tub Heaters: How To Choose The Right One

I asked my buddy which of the 3 heating systems he’d use if he were to build a hot tub, and he answered none of them. When I asked him again (this time more seriously), he decided to go with electric hot tub heaters. But of course, being the sarcastic and ignorant clown he is, he obviously didn’t give much thought to his reply and overlooked the pros and cons of each system.

When choosing a certain heating setup, it’s important that you understand the advantages and disadvantages that come with each one. You also have to take into consideration how much money you earn, and if it’s possible to squeeze it into that tight budget of yours.

So first of all, let’s take a closer look at the selection of my friend, namely: electric hot tub heaters. The initial cost of getting this installed is relatively low, plus you can easily install it anywhere, so long as there’s a standard hook-up.

Repair and maintenance is in some sense “effortless”, especially since the replacement parts are available everywhere. However, the biggest disadvantage here is the time it takes to heat up a pool of water, which can be quite long. Moreover, because it uses a lot of electricity, your electric bill will definitely go up.

Next, we have using firewood to keep the tub nice and hot. The good thing about this method of heating is the fact that it heats the water at a much faster rate, and costs a lot less than using electric hot tub heaters or gas. You can even use coal if you’d like, making it even more cost-effective. On the other hand, utilizing fire or coal for every type of plunge bath won’t do, simply coz they aren’t designed for this heating scheme. Wood fire can only work for specially designed personal spas only.

Lastly, we have gas for keeping your private pool of water heated. The largest benefit users may enjoy is its ability to get the water to the desired temperatures in a short span of time. Great for tubs built in the ground, gas heaters are cheaper than using electric hot tub heaters, but more expensive than using actual fire.

These are just 3 of other methods that you can choose to keep the temperature of that plunge bath of yours to your liking. All you have to do now is recognize the pro and cons of each, and pick one that’s best suited for your needs.

Hot Tub Installation Guidelines and Requirements

A hot tub is an excellent investment for your home. What could be better than coming home after a long day to your own relaxing spa, filled with warm water. Most hot tubs are located outdoors, making them a great place to relax, even in the wintertime. However, some models can also be installed inside.

Many people hire professionals to do their hot tub installation, but you’ve got the tools and know how, you can do it yourself. Unless you’re experienced, you’ll probably need to have a professional run any gas lines required for the heater, and install the electrical circuit needed for the pump. However, you should be able to perform all other aspects of hot tub installation on your own.

There are a few things you should pay attention to when installing your own hot tub. The first part of any hot tub installation is appropriate planning. Most people use their hot tub more frequently when it’s placed close to the house, or, if inside the house, close to the bedroom. You’ll need to have adequate support, wherever you choose to locate your hot tub. The average filled tub weights over five thousand pounds. This means that it might be hard to install a hot tub on your existing deck, since most aren’t engineered for this kind of weight.

Your hot tub must sit on a solid surface. A concrete pad is common for outdoor hot tub installations. Be sure that it’s thick enough to prevent settling, which could cause the hot tub to develop leaks. If your hot tub is very tall, you may want to sink it into the ground slightly, by digging an appropriately sized pit for the concrete pad to rest in. If you sink your tub, it will have to be assembled above ground, then placed in the hole.

For indoor hot tub installations, there are different considerations. The biggest one is how to deal with moisture accumulation. When you remove the insulating cover of the hot tub to use it, a large amount of steam can accumulate in the room. Potentially, moisture retention in rooms can lead to mildew and other problems. Therefore, you should make certain the room for your hot tub installation is one with good ventilation.

If your hot tub is inside, you should also take chemical use into account. If you use chlorine or bromine to sanitize your tub regularly, there can be a fairly large amount of off-gassing. Instead, try using an ionizer or other less dangerous sanitizer. The good news is that since indoor hot tub installations usually are exposed to less dirt and debris, you won’t have to sanitize them as often.

Once you have a location for your hot tub, you’ll need to consider the equipment. National code required that you locate this equipment at least five feet away from the tub, unless you separate the two with a permanent solid barrier. Many people locate it much further away, since one of the advantages of a hot tub over portable spas is not having to sit on top of the noisy equipment.

If you’re going to located the pump and piping more than fifty feet from your hot tub, be sure to up-size them to prevent loss of pressure in the jets. Likewise, if you locate your heater more than five feet below the tub’s water level, you’ll have to adjust it. Heaters located more than ten feet below this level will need a special flow switch. Try to install your pump below the water level of the tub. Pumps located higher up can lose their prime, ceasing circulation of water and damaging the pump.
