HEATING TIME OF AN ELECTRIC OUTDOOR HOT TUB WHIRLPOOL

When purchasing a hot tub the rather extensive selection regarding the various parts may be daunting for some. For this very reason, we at TimberIN try to make this process as simple, informative and smooth as possible. One of the most frequent inquiries of our clients is the expected heat generation of the electric heaters available. To explain what one may expect when purchasing an electric heater, we have prepared this theoretical heat calculation model. Please keep in mind, that the information provided is based on zero heat loss.

 The general formula for calculating the time required to reach a specific change in temperature

  •  Power required to increase water temperature by ΔT degrees in a fixed time (t), assuming no heat loss:

Formule1

  • Time is taken to increase water temperature by ΔT degrees from a fixed power input, assuming no heat loss:

Example: Time is taken to heat 2 m3 of water from 10°C to 35°C with a 9-kW heater, assuming no heat loss:

Ofuro hot tub heating time

 

To save our clients time, we have pre-calculated the approximate heating time for some of our most popular hot tub models. Firstly, comes one of the smallest models, the Japanese Ofuro Bath for 2 persons with polypropylene liner. This model is ideal for clients with limited space, it provides coziness and intimacy without losing the functionality and quality of a larger tub. The polypropylene liner provides a possibility for an air bubble massage system, as well as, a hydro massage system to be installed creating an enhanced experience of the classic hot tub. Polypropylene also provides a waterproof environment; therefore, a client doesn’t have to worry about potential leaks, due to the change of weather. A wide selection of wood types, colors and LED lighting provides a possibility to both personalize, customize and tailor the hot tub to both its surroundings and the clients’ personal taste.

Ofuro

In the case of this model, an electric heater is quite a popular choice, as it provides a clean atmosphere, high mobility and requires minimal maintenance. Regarding heating up water, the volume of the object in question is one of the most important factors. In this case, the coziness of the Ofuro becomes an even bigger advantage as the heating time drops. The inside benches and the slope of the walls reduce the overall water volume even more. For example, if a client were to heat up the water from 10°C to 35°C with a 6-kW heater, the approximate time calculation, would look like this:

Nevertheless, clients who are who are interested in luxurious comfortable and relaxing experiences for both family and friends should look no further than the Wellness Royal model. The best seller of 2017 continues to provide unforgettable moments for clients from all around Europe.

Much like the previously mentioned Ofuro model, the Wellness Royal provides even more customizability options to satisfy every need of the user. As this model is considerably larger in volume, higher output electric heaters can be accommodated to increase the speed at which the water is heated. For example, if a client were to heat up the water from 10°C to 35°C with a 9-kW heater, the approximate time calculation, would look like this:
