Energy costs are rising worldwide, which is impacting people’s lifestyles. If you have a hot tub installed in your home, heating all that water must be costing you a lot. If you are thinking of heating that water with a boiler and saving some money over the heating costs, you’ve come to the right place.
Answering the question in the title: Yes, you can heat your hot tub with a boiler, and it is very economical to do so. There is no harm there. But to do it properly, you will need the right type of boiler.
Generally, there are three types of boilers: conventional boiler, combi boiler, and system boiler. A conventional boiler can heat a large amount of water in one go because there is a tank attached to it. The combi boiler is for small places that need immediate heating. The system boiler has connected cylinders and radiators, which increase its storage capacity, so they are good for medium-sized areas.
With this in mind, a conventional boiler is likely to be the best type of boiler for hot tubs. If you already have a boiler at home and you are thinking of replacing it, you need to consider the cost of boiler replacement. But before you go and buy a conventional boiler, here are some questions you need to consider.
Why do you want to use a boiler to heat your Hot Tub?
For starters, it’s cheaper to heat a hot tub with a boiler. If you already have a conventional boiler with a large tank installed in your home, then you can simply connect it to your hot tub. For people looking to upgrade their home heating system with a new boiler, we recommend that they buy a conventional boiler with a large tank this time around. You can connect it to your hot tub and save a considerable amount of money and resources in using it. If you have the right-sized boiler unit, you can easily heat a hot tub in no time.
How can you heat your hot tub using a boiler?
You can install a separate heat exchanger unit to get this done. The separate heat exchanger unit will generate enough heat to raise the temperature of both your home and your hot tub. Once again, you need to ensure that you have the right sized boiler, a boiler that fits both your home and hot tub needs.
What is a heat exchanger, and how does it work?
The term “heat exchanger” may lead you to think that it is something complicated that you will have trouble with. However, a heat exchanger is a simple device that circulates the hot water from your boiler around the exterior of the heat exchanger, thus heating it. The heat is then transferred to your hot tub, and you get to enjoy those relaxing baths.
Let’s explain how the heat from the heat exchanger is transferred to the hot tub. While remaining isolated from the water in the boiler tank, the water in the hot tub passes through the heat exchanger unit. As it passes, the heat in the heat exchanger is transferred to the water through contact, and the temperature of the water rises. It is a very simple procedure and also quite effective.
So how exactly does this save me money?
Boilers are not just for heating water. Boilers do heat water, and this heated water has many uses. People living in cold regions used large conventional boilers to heat their homes. If you are one of these people, then you are already paying for running your boiler to heat your living spaces and water.
The heat exchanger uses the heat that is already being produced and uses it to heat the water in your hot tub. This way, you don’t have to install a separate heating unit and pay for heating that up as well.
Conclusion
Using a boiler to heat the water in a hot tub is not ideal, but it is very cost-efficient and safe. Using a heat exchanger keeps things isolated and leverages the extra heat produced to enjoy your hot tub. If you are getting a new boiler, consider a conventional one to make the most of your hot tub!
