大多数热水浴缸都配有一个一体式电加热器，根据水容量的不同，输出功率通常在3kW左右。然而，最近，通过外部锅炉使用燃气加热的趋势日渐盛行，因为与电加热相比，这种方式加热水的速度更快。这意味着当您不使用热水浴缸时，可以将其保持在一个较低的温度，甚至可以完全关闭加热器。因为，当您准备使用热水浴缸时，无需花费很长时间便可达到所需温度。

而采用电加热器加热浴缸所需的时间很长，在使用冷水的情况下通常长达24小时。为了加快加热速度，一些业主采用锅炉热水“预先注入”浴缸，但即使这样，也需要再加热6到10个小时，才能达到所需的38-40°C。

虽然许多家庭用户为忍受这种不便做好了准备，但对于度假公园之类的商业用户来说，这种情况是无法接受的！

在假日住宿预订中，对热水浴缸的需求已经大幅上升，目前已成为位列第二的客户需求设施。为满足这一需求，度假区必须寻找一种更快的方式来加热浴缸水，因为客户更迭期间时间紧迫。一般来说，在新客人到来之前，只有大约4-5个小时的时间进行浴缸排水、清洁、重新注水和加热。

解决方案相对简单——使用一个燃气锅炉之类的外部热源，简单地旁通热水浴缸电加热器。为了实现这一点，需要使用换热器将锅炉水的热量传递到浴缸水中。这和大多数游泳池加热的原理完全相同，只是规模较小。

为此，Bowman开发了一种超紧凑型换热器，能够安装在热水浴缸管道系统中，最终，采用冷水加热浴缸需3-4小时，采用预热水加热则只需1小时左右。

此外，还有另一个好处。电加热通常较为昂贵，通过改用燃气锅炉加热后，根据众多用户的反馈，能源成本得到了大幅降低。之前，一些用户的单个浴缸加热成本高达500英镑！

度假区如何从改用燃气加热中受益。

As their name suggests, hot tubs require a lot of heat to achieve and maintain the 38°C to 40°C water temperature they usually run at.

Most hot tubs are supplied as standard with an electric heater already installed. This usually takes many hours to heat a typical 1,400 litre hot tub from ambient water temperature to normal operating temperature, and as electricity is one of the most expensive ways of heating, it’s not surprising that many users find their electricity costs rise sharply!

A more efficient solution is to heat the hot tub from an external heat source, such as a gas boiler. Usually, this can be done by connecting pipework from the hot tub to the boiler, in a similar way to adding a new radiator to a new room in a home.

The only difference is the hot tub requires a heat exchanger to act as an interface to keep the pool and the boiler water separate from each other. Installing the heat exchanger into the pool water circuit and connecting to the boiler is straightforward, though a plumber may be required to install.

Once the hot tub is being heated from the house boiler, many users notice how much quicker the water temperature increases and in many cases, the hot tub can be ready to use in just 2 -3 hours of heating, which is a real bonus, as it significantly reduces the energy used and, as gas heating costs are much lower than electricity, energy costs are significantly reduced too!

Bowman has been one of the pioneers in providing hot tub heating via heat exchangers and have a comprehensive range of products for this specific application. For more information on Bowman Hot Tub Heat Exchangers
