Also known as hot tub heaters, these machines are essential to control, maintain and adjust the warmth and temperature of the water. There are many types of hot tub heaters, among them the electric resistance device is more popular and predominantly used since it is more energy efficient and cost effective. If you are unaware about the device and its method of work, here is some information that will give you insight.
What is an Electric Resistance Heater?
Among many of the available heating methods for hot tubs and spas, the electric resistance is the ultimate choice. It is an electrically charged device that operates with automatically. It is main purpose – similar to any ordinary heater – is to maintain and provide the right amount of temperature to the hot tub. But what is different in this particular product is that, it requires very little human effort and meddling and enables the user to lie back and enjoy the warmth of the water.
How does it Work?
The spa heater creates applies electric current to the metal resistor. This in turn results in the creation of heat. With it, the resistor is able to extend to the rest of the assemble housing inside the heater. This spreads the heat through the entire unit. When the spa water reaches the assembly housing, the water’s temperature will increase due to the unit’s heat. This enables the water to exit as in a warm condition.
What are its Advantages?
If you are familiar with the benefits of a gas heater, then do know that a spa heater offers more or less the same benefits to its user. Since operates with air temperature you will be able to experience excellent service during the winter season. The purchase and installation costs are very low when compared to other heaters in the market. Furthermore, electric resistance heaters are environmentally friendly as well.
What are its Disadvantages?
When compared to a heat pump, this device is 6 times less efficient. This low efficiency levels makes the device to consume a large amount of electricity to operate. This is one of the main reasons why it is not used to heat swimming pools. Moreover, these heaters also require thorough management and thus have heavy maintenance costs as well.
Therefore, even though the device offers incredible performance capacity, do know that you need to spend quite a lot to experience it. So, unless you have large budget set aside for your hot tub, it is wiser to use a regular heat pump.
