What is better than to arrive from hard work and get into a hot tub or spa to relax and rejuvenate sore muscles and joints?
Surely it will make you feel amazing and shortly stress-free. This works only if the spa/tub operates with the hot water.
This is why you should buy one of the quality electric spa heaters. Electric-powered spa heaters are designed to provide reliable, high-performing and efficient operation for a long time, no matter the climate. Here we will tell you why electric spa heaters are so useful and why you need one!
Electric spa heaters are very similar to the heaters you use for heating pools. They have the same pumping feature, come in similar cabinets, and sometimes even work for both spas and pools without problems. However, not all of them will offer the same effect you are looking for.
This makes it not only harder to choose but somehow confusing, so we’ve decided to give you a better idea of what to go for and how to pick the right one. Keep reading and find out!
We all know that when it comes to effectiveness, gas heaters may win the whole battle. However, the gas is often affecting the environment, costs a lot, and makes devices prone to break faster due to constant exposure to fire and gas combustion.
Then you have heat pumps, which are superbly efficient but don’t offer as much performance – they heat water much slower than other types. They cost more at first, and installation costs may also go up exponentially. Yet, they offer little to none damage to the environment.
Electric spa heaters, on the other hand, are more efficient, provide superior heating, don’t damage the environment as much, and can still be as effective as a gas heater or even more efficient. Sometimes, electric heaters are even cheaper than gas heaters, so you have outstanding results just there.
Here are a few other advantages you get with electric spa heaters:
Perfect for moderate climates: work better in warmer areas but mildly cold places are also fitting
Efficiency is over 90% which is better than in gas heaters, and energy consumption is lowered exponentially
Electric spa heaters can be installed practically anywhere: they are small, don’t weigh as much, and provide convenient designs
Operating an electric heater is simple
Much quieter and stress-free: they work seamlessly without problems causing little to no noise even at high-performance levels
Cleaner water and environment
The electric heaters come with a power measurement in BTU or kW. This tells you how powerful, and how much heating capacity can a device provide. Normally, spa heaters have between 40,000 and 150,000 BTU. This is more than enough for small, medium and large-sized spas. However, you may find some that have even more BTU and provide superior performance, faster heating capacity, and eventually fit larger spas or pools.
Another way to know the capacity of a heater is by looking into its wattage. Generally, spa heaters come in power ranging from 1.5 kW models to 11 kW models, even up to 15 kW for the larger spas. Of course, the less kW available, the less power a device has.
Now that you know about BTU or spa capacity, it is time to learn what size you need to look for. It is important to know all the measurements of your hot tub or spa as well as the amount of water (in gallons) it normally works with (or volume). This way you will be able to make a better decision on what heater to buy.
We recommend using the old and effective measurement of 700 BTU for each gallon of water. This means, that for every 70,000 BTU, you will be able to heat up a 100-gallon spa in less than one hour.
For kW measured heaters, you should know that 1 kW of power heats up a gallon of water in seven minutes. Or, by using the 5.5 kW heater, you can heat up 100 gallons of water in 80 minutes.
However, it all depends on the efficiency of the heater you choose and the desired temperature. Higher temperatures will obviously take more time to achieve than you may think.
Desired temperature range for any spa is between 101 and 103 F (should not exceed 104 F) and since the spas are thermostatically controlled, the danger of exposing yourself to high temperatures is significantly reduced.
Note: Heat-up time, as the time required to heat the water to the desired temperature, is an important detail to use when sizing the heater.
You might also want to take into consideration the wind speed and altitude as those can increase the surface heat loss. Or, the shade, because it might be the reason why you need to upsize the heater.
Overall, you could say it offers around 40,000 BTU in its largest model. With a great power, reliable stainless steel construction and an excellent user-friendly interface, the heater may be a magnificent choice for any homeowner.
