How to Buy Water Heaters for Your Bathroom the Right Way

The technology for bathroom water heaters has been changing at a relatively fast pace with unique and highly efficient heaters being produced presently.

There are very many models of these heaters with some being better than others in terms of efficiency and ease of use.

Sophistication and complexity of the heater 

Bathroom water heater manufacturers design their products exclusively and differently from each other.

This leads to varying levels of sophistication and complexity in the heaters.

While sophistication is a good thing in that it enhances the uniqueness of a heater, complexity may interfere with the ease of use of the heater.

Heaters that are too complex are not only hard to install and operate but may also be quite expensive to maintain since they require specialized attention from the best technicians.

Fuel consumption 

Bathroom water heaters can be very costly to operate particularly if their fuel consumption is very high.

Other than solar-powered heaters, fuel consumption plays a very important role when identifying the best model to buy.

For example, if you buy a heater whose electricity consumption is very high, it becomes very uneconomical to afford the use of such a heater in the long run.

Therefore, you will have to dig deeper into your pocket when paying your energy bills.

Solar-powered heaters are usually the best option as they are very affordable to use since the sun is a free fuel.


The best bathroom water heater should address your needs for a compact size heater.

If you have a fairly big tub, you will need to settle on a large-size heater.

These heaters are able to warm a large volume of water at once without straining their efficiency or output ability.

Likewise, if your bathroom/tub is small, you should look for a relatively small heater that will address your preferences.

After you have decided on the best water heater type that is right for you, you should shop for the top rated ones in efficient water heater.

The Energy Factor is the best indicator to rely on when determining the rating efficiency.

This factor refers to how efficiently energy is passed from its source to the water for heating purposes.

It also puts into consideration the standby and cycling losses.

Products with high EFs are more efficient and have very few energy losses.

It is worth noting that all manufacturers include the EF on the heater’s energy guide labels.

It is therefore easy to compare different EFs for various heater models.

Comparing costs 

Cost is a very important consideration you need to keep in mind also.

The actual cost of a heater is not only the purchase price of the heater.

You should also include an estimate of the operation expenses and maintenance costs that will be incurred throughout the lifetime of the heater.

When choosing the ideal heater to purchase, you should analyze the total life cycle cost of the heater and its associated benefits.

Is the overall cost of the heater comparable to its efficiency, reliability and benefits of use?

If yes, then buying that heater is a worthy investment.

Usually, the cheapest unit to purchase is also the most expensive to operate and maintain.

In addition to this, cheap products have very short warranties if any.

Purchasing a heater with a long warranty is very beneficial in the long run as it helps you in making substantial savings in case the heater because faulty or non-functional while the warranty is still valid.

The criteria for selection of these heaters should be based on the pros and cons of the heaters in respect to your specific needs and preferences in bathroom water heaters.

There are numerous considerations to make and as such, you should not settle on any water heater unless it is fully satisfactory to you.
