How to keep your bathtub water hot?

Keeping the bath water hot is a simple task. If you have not already done so, you should check to see if your house has a boiler or furnace that provides hot water. If not, then you will need to purchase one otherwise known as an immersion heater which is installed in your bathroom and heats up on demand by turning on a tap.

How to keep your bathtub water hot?

There are lots of ways to keep your bathwater from cooling down too quickly, so try them all until you find what works for you!

Get the hottest water you can

You want hot water that’s as hot as possible. The best way to do this is to use a hot water heater. Hot water heaters are great because they can hold large amounts of hot water for long periods of time (12-24 hours). They also tend to be very efficient, providing you with the most energy-efficient option for keeping your bathtub warm all day long.

Because there are so many different types of hot water heaters on the market today, it’s important to know what kind will work best for you and your lifestyle. Your options include:

  • Electric – These are inexpensive and easy to install, but they require electricity in order to run properly and may not provide enough heat if there’s no power source nearby.
  • Gas – They need fewer parts than an electric heater but still require fuel such as propane or natural gas; some models allow users access their own supplies while others must be filled with their respective fuels before using them outdoors or indoors depending on how often they’re used per day/weekend/etcetera.

Use a low-flow shower head

A low-flow shower head is the best way to keep your shower hot for longer. Not only does it save you money on water bills, but it also saves you from wasting all that water and makes your tub last longer as well.

If you have a thermostatic mixer valve (TSV), this will automatically control the temperature of your bath by regulating the flow rate of hot or cold water, so if one end is hotter than the other, then this will be able to balance itself out without any problems.

Fill the tub with cold water first

When you are filling a bath, always fill it with cold water first. This will prevent your pipes from heating up too quickly and causing them to burst or leak. Once the tub is full of cool water, add just enough hot water to get the temperature that you want for your bath (while still being comfortable). If you have an electric boiler for your bathroom or home, this can be an expensive mistake!

Turn on the hot water and start filling it up

To keep your bathtub water hot, you need to turn on the hot water and start filling it up. Hot water takes longer to cool down than cold water, which means that if you turn on the faucet with a high flow rate of hot water, the temperature won’t drop as fast as if you had turned on a fast-flowing stream of cold water.

The more gallons per minute (GPM) of hot water that’s coming out of your faucet, the faster its temperature will drop once it enters your tub. So if you want to keep your bathtub as warm as possible for an extended period of time, try turning down the GPM flow rate of whatever device is supplying heat to it so that less heat escapes into areas where it isn’t needed (such as outside). You can do this by using something called a “combination diverter valve” or “mixing valve.” This device has two different spouts: one that supplies only cold tapwater and another that supplies only warm tapwater plus some sort of heating element (like an electric element). By switching between these two spouts manually or automatically through an electronic controller. You can control how much hot or cold fluid flows into your bath at any given moment.

Keep your bathroom door closed

Keeping your bathroom door shut can help keep the heat in and the cold air out, which will make sure that you have a hot tub all night long. If you have a shower curtain, try using it to cover up any gaps around your door so that water doesn’t escape as easily (and leave you feeling colder).

Cover the tub after you get out of it

It’s a common mistake to leave the water on while you’re showering and then be surprised when it cools down. If you want hot water, turn off the faucet while you’re in the shower, or fill a bucket with warm water and use it to rinse yourself off.

Once you’ve gotten out of the tub and your skin is dry, cover it up with a towel (or two), shower curtain, bath mat, anything that will keep air from reaching your body as much as possible. Air causes condensation on cold surfaces.

Conclusion

You can also try using a bathtub heater or an inflatable tub if you don’t want to wait for your water to get hot.
