Hot tub with external heater

What types of external hot tub heaters are there?

There are several external hot tub heaters. An external hot tub heater, as the name suggests, is always outside the hot tub. If you then look at the types and differences you will see this in the materials and also in the models. For example, you have external hot tub heaters that stand on the ground, but also those that are attached and suspended to the hot tub. In terms of material, you see mostly external hot tub heaters made of aluminum, stainless steel 304 and or stainless 316. 

External heaters are ideal for those who want to combine efficiency and aesthetics, as they are placed outside the hot tub, keeping the interior spacious and free for relaxation. At Welvaere you will find three different hot tub heaters that ensure that the water in the hot tub becomes wonderfully warm. The Welstove Medium, Welstove Large and the Welstove Pro. All three are beautiful and user-friendly hot tub heaters. We give you the opportunity to choose the heater you like best or the one that fits your budget.

Cost of an external hot tub heater

How long does it take for a hot tub to warm up with an external heater?

The heating time of a hot tub is affected by several elements, including the size of the Ducktub, the insulation present, the efficiency of the external hot tub heater, the outside temperature and the type of wood used for firing. When you heat the hot tub with an external stove, heating takes about 2 hours. Our smallest hot tub holds about 800 liters and the largest about 1700 liters. With the latter external stove hot tub, it takes about three hours for the water to be wonderfully warm.

How hot does the external heater of a hot tub get?

The external hot tub heater does not get hot itself. This is due to its unique two-compartment design. The inner one where the fire burns and an enclosing compartment filled with water. This ensures that the outside of the stove stays cool while the water is heated efficiently. The external hot tub heater heats the water to an average of 38 to 40 degrees Celsius. Depending on how intensely you fire, the temperature can go higher, as the stove does not have a fixed temperature setting, which means the water can get warmer.
