Immersion Water Heaters for Bathtubs: A Guide
Do you love long, hot baths but hate waiting for your water to heat up? If so, an immersion water heater for your bathtub may be the perfect solution for you. Immersion water heaters are small, portable devices that you can place in your bathtub to heat the water quickly and efficiently. They’re also relatively inexpensive, making them a great option for budget-minded consumers.
In this guide, I’ll discuss everything you need to know about immersion water heaters for bathtubs. I’ll cover topics such as how they work, what features to look for when shopping, and how to install and use one. By the end of this guide, you’ll be able to make an informed decision about whether or not an immersion water heater is right for you.
How Immersion Water Heaters Work
Immersion water heaters work by passing electricity through a metal element submerged in water. This causes the element to heat up, which in turn heats the water. The amount of heat produced by the element is determined by its wattage. The higher the wattage, the more heat the element will produce.
Immersion water heaters are typically rated in gallons per minute (GPM). This refers to the amount of water that the heater can heat in one minute. The higher the GPM rating, the faster the heater will be able to heat your bathwater.
Features to Look for When Shopping
When shopping for an immersion water heater for your bathtub, there are a few things you should keep in mind.
- Wattage: The wattage of the heater will determine how much heat it can produce. If you have a large bathtub, you’ll need a heater with a higher wattage.
- GPM rating: The GPM rating of the heater will determine how fast it can heat your bathwater. If you’re in a hurry, you’ll want a heater with a higher GPM rating.
- Temperature control: Some immersion water heaters come with a built-in thermostat that allows you to control the water temperature. This can be a helpful feature if you have specific temperature preferences.
- Safety features: Some immersion water heaters come with safety features such as a thermal fuse and an anti-scald feature. These features can help to prevent accidents, such as burns.
Installing and Using an Immersion Water Heater
Installing an immersion water heater is a relatively simple task. Most heaters come with instructions, but you can also find detailed instructions online.
To install an immersion water heater, you’ll need to:
1. Locate a suitable location for the heater. The heater should be placed in a location where it will be protected from water and moisture.
2. Connect the heater to the power supply. The heater should be connected to a GFCI-protected outlet.
3. Attach the heater to the bathtub faucet. The heater should be attached to the faucet using the included hose and clamps.
Once the heater is installed, you can use it to heat your bathwater. To do this, simply turn on the faucet and let the water flow through the heater. The water will heat up as it passes through the heater, and you can adjust the temperature using the thermostat (if your heater has one).
Immersion water heaters for bathtubs are a great way to enjoy long, hot baths without having to wait for your water to heat up. They’re relatively inexpensive, easy to install and use, and come with a variety of features to choose from. If you’re looking for a way to improve your bathtime experience, an immersion water heater is a great option.
