My Buying Guide on ‘Best Water Heater For Bathtub’

As someone who loves taking long and relaxing baths, I understand the importance of having a good water heater for your bathtub. A good water heater not only provides warm and comfortable water for your bath but also helps in reducing your energy bills. With so many options available in the market, it can be overwhelming to choose the best water heater for your bathtub. After thorough research and personal experience, I have compiled a buying guide to help you in choosing the best water heater for your bathtub.

1. Type of Water Heater

The first thing to consider when buying a water heater for your bathtub is the type of water heater you want. There are three types of water heaters available: tankless, storage tank, and heat pump. Tankless water heaters provide hot water on demand and are suitable for smaller bathtubs. Storage tank heaters store hot water in a tank and are suitable for larger tubs. Heat pump heaters use electricity to transfer heat from the air or ground to heat your bathtub’s water.

2. Size

The size of the water heater is crucial when choosing one for your bathtub. You need to consider the size of your tub, how much hot water you need, and how often you use it. For smaller bathtubs, a 30-gallon tank should be sufficient, while larger tubs may require 50-80 gallons.

3. Energy Efficiency

A good quality water heater should be energy efficient as it can help in reducing your energy bills in the long run. Look for a model with an Energy Star rating as it means that it meets the energy efficiency guidelines set by the government.

4. Heating Speed

The heating speed of a water heater is essential if you don’t want to wait too long for hot water in your bathtub. Tankless heaters provide hot water instantly, while storage tank heaters may take some time to heat up depending on their size.

5. Durability

You want to invest in a durable and long-lasting water heater that can withstand regular usage without any issues. Look for models with corrosion-resistant materials like stainless steel or glass-lined tanks.

6. Temperature Control

Having control over the temperature of your bathwater is crucial when choosing a good quality water heater for your bathtub. Look for models with adjustable temperature controls or digital displays that allow you to set and maintain your desired temperature easily.

7.Age of Your Current Water Heater

If you already have a working water heater but are looking to upgrade, consider its age before making a purchase decision. Most heaters have an average lifespan of 8-12 years, so if yours is nearing its end, it might be time to invest in a new one.

8.Warranty

A warranty is crucial when buying any appliance as it provides peace of mind and protects you from any manufacturing defects or malfunctions within a specific period after purchase. Look for models with at least a 5-year warranty on parts and labor.

In conclusion, investing in a good quality water heater is essential if you want to enjoy warm and comfortable baths without breaking the bank on energy bills. Consider these factors when purchasing one and make sure to do thorough research on different brands before making a final decision.
I hope this buying guide helps you in finding the best water heater for your bathtub!
