The Best Appliance to Heat Bathwater
Bathwater Not Hot Enough?
There are a lot of reasons why you can have access to electricity but not hot bathwater--or at least not piping hot bathwater. In my case, it is a condo building with a shared hot water tank that is set lower than I like and gets even cooler during busy times of the day. Other people might be dealing with a malfunctioning or undersized hot water tank or just want to heat up a tub on their deck or even outside.
In-Line Water Heaters
There is a range of options that require a plumber such as point-of-use water heaters that are installed into the water supply. This comes with an extra cost, and may not be an option if you are a tenant.
Stove or Kettle
Many online pages recommended heating water in a kettle or on a stove and taking it to the bath. This option is laborious and potentially quite dangerous.
The general category I decided to use was a safe electrical appliance specifically designed for heating water.
Selecting a Plug-In Appliance
Electricity and water are always a dangerous combination. So it is vital to choose an appliance with the following qualities:
- It must be specifically designed to heat water.
- The heating element must have a safety guard to prevent burns or damage to the tub.
You also need to ensure you use a power point that has a fuse and with not be splashed by any water.
There are no appliances specifically made to heat bath water. What you need to look for is a submersible heater or bucket heater. You need it to be able to heat a relatively large volume of water to your desired temperature.
I would suggest looking for a minimum of 1000 watts, able to heat to 130 degrees Fahrenheit or thereabouts.
Do NOT Select a De-Icer
Many heating appliances have the goal of just preventing water from freezing. These are used to keep water drinkable for animals or stop a fish pond from getting too cold in winter. This kind of heater will turn itself of long before the water gets piping hot.
The Best Option
I went through a period of trial and error using heater from Farm Innovators, Allied Precision, and others. I found most of these to be seriously underpowered and to take more than two hours to heat water and to not heat the water enough.
I ultimately found the right product with the 1500W immersion heater from Gesial -- listed below. This heater has a good guard, can be placed fully under the water, and got a full tub of water piping hot in under two hours. That seems to be about as good as it gets with this kind of appliance.
- Always ensure the heating element is fully covered by water before plugging it in.
- Pug into a power point with working fuse well away from the water.
- Unplug and remove the element before entering the bath.
