Best Hybrid Water Heater

Trying to shift the gears and go on the next level with your water heater? Choosing a proper water heater is very important for you. If you are looking to get a new heater to fulfill your requirements, choosing a hybrid water heater can be a top-notch choice for you. Gone are those days when everyone would like to get a simple water heater.

Since the arrival of hybrid technology, almost everyone is about to switch to the new technology. However, there are multiple products to choose from. If you are confused about choosing the best product available for you, this guide on Best Hybrid Water Heaters will help you to find the one for you.

The basic concept of a hybrid hot water heater is a fusion of both electrical and gas technology involved in a heater. It is a modern form of a heater that is available with the latest technology. If you are finding it difficult to understand, the hybrid water heaters are a combination of the regular heaters with the technologies of a tankless heater.

In the case of a hybrid hot water heater, the components are present like any that can be available at your home. However, the mechanism seems to be slightly different than any regular water heater available for the home.

How Do Hybrid Hot Water Heaters Work?

Coming to the mechanism of the Hybrid Heaters, this seems to be simple but with new and time-cutting technology. Thus with the help of this mechanism, any user can get on-demand hot water without any issues. The basic concept is to move the hot air from the pipe to the water tank.

However, when it comes to meet the high demand for water heaters, the mechanism involves a direct change. In such a case, the hybrid water heaters start with the help of electrical heating technology.

Coming to the settings, they have additional technologies involved. This will also influence on saving electricity and expenses on heating. The mechanism involves low electricity consumption as well as limited gas consumption.

Hybrid Water Heaters V/S Other Water Heaters

If you are confused about what you should choose between the three, it is very important to know the real difference between the heaters. There are mainly two categories that you can follow up including the work procedure as well as the uses.

However, coming to the types of multiple water heaters being used, there are three types including the hybrid, tankless electric and the traditional heaters. Below, we have compared all three of them according to the mechanism and the uses.

A. Regular Heater

Mechanism of Work

When it comes to the traditional type of storage, the mechanism of this type of heater is just like the common models. Here, the heating is done inside an insulated tank within the product.

Once the water gets heated, it tends to be stored down within the insulated tank. After this, it is flown through the overhead pipe present on top of the tank.

Usage and Benefit

The usage of the storage water heaters depends on the amount of storage that you need to consider. So you must consider the right amount of tank storage for your needs.

If you are willing to buy one, your product must have a high capacity for a storage tank. Since the regular heaters come with a high capacity, it helps homes with multiple hot water faucets running together.

Energy source

Coming to the energy source of the Regular Heater, most of the products are either powered by gas or by electricity. However, the cost of the models with electricity or by gas can be difficult to deal with. Coming to energy and consumption, the gas-powered models are much more efficient than most of the electric-based models. 

B. Tankless Water Heater

Mechanism of Work

Most of the Tankless Heaters are different from the regular heaters when it comes to the mechanism of work. Mostly, they are known for the on-demand hot water supply. The mechanism is however very simple and the heating is done on the pipe and not in the heater. While the water flows through the pipe, it directly heats the water on-demand.

Usage and Benefit

The usage of the Tankless Heater depends on the gallons per minute. Unlike the capacity of the tank based models, here, the factor depends on how much water it can heat per minute.

This mechanism is very useful for people who do not have much time to wait while taking a shower. Just switching on the heater will provide on-demand hot water.

Energy source

Just like the regular models, the energy source for the Tankless Heaters is done with the help of either gas-based models or the electricity-based models. Natural gas may be used as a mode of fuel for heating the water. However, if you wish to get an electric-based model, you must have a complete electrical upgrade.

C. Hybrid Hot Water Heater

Mechanism of Work

The mechanism and work of the Hybrid water Heater is a combination of the above two procedures. It works mainly like a regular heater which can heat the water tank fast and effectively. Here, the water tank is present at the bottom of the water heater. However, when it requires fast and on-demand heating, you just need to switch the mode. It can directly use electricity to heat faster.

Usage and Benefit

This Water Heater is a great way to suit the hot water needs of any home. It has a specialized switch mode option which can easily allow you to get the hot water supply that you need.

They come with a specified control panel which allows you to change the settings at any time. It has a high capacity which can provide the requirements of a whole family.

Energy source

These water heaters use a combination of gas and electricity. Most of them come with power savers as well as energy efficiency which helps to increase the energy factor. Because of the dual power source, they are capable of heating the water based on both efficiencies as well as usage.

Benefits of Having a Hybrid Hot Water Heater

Ever since the Benefits of Having a Hybrid water Heater has been developed, several people have been attracted to the concept of using such a heater. However, if you are willing to buy one, here is a list of benefits that you can get after purchasing.

1. Energy Consumption

The energy consumption of this water heater is a great benefit for using such a model. In any heater, the energy source is mainly done with the help of natural Propane gas. This increases efficiency. But in the case of these heaters, the primary heating option is gas-based. In fact, it also allows you to switch to the electric-based models when it comes to on-demand heating option. This makes most of the hybrid models high in energy efficiency.

2. Maintenance

The maintenance of the Hybrid models is quite efficient. The maintenance is very low which allows you to easily manage the product for long. Comparing the other heater types, the installation for the Hybrid Heater is also the same. So it is barely on the low side where you may not have to pay too much for maintenance.

3. Durable

Coming to the interior components of the product, they have high-quality heating elements. There are two different heating elements present in such heaters and they appear to be working great. Because of the high-quality materials, one can easily use the heater for both indoor and outdoor uses.

4. Long Life

Most of the Hybrid Heater comes with a long warranty on the product. If you choose from any reliable brand, you will get at least a 10-year warranty on the heating component. Apart from this, you can also get a minimum of a 5-year warranty on the interior component. So it would be ideal to say that they will have a minimum of 20-year lifespan with the product.

5. Low electricity bills

They come with energy efficiency factor and UEF ratings closer to 1. Since there are two heating elements, the basic heating is done with the help of gas fuel. So this will automatically reduce the amount of electricity bill which will make sure that the running cost of the product is lower.

You may end up purchasing a short-lasting Hybrid water Heater. So eventually you’ll end up paying more. To get rid of this, you can opt to pick a proper one which will give you the best features in a budget-friendly model.

3. Features

There are certain features that you must always keep in mind while purchasing the Hybrid hot water Heater. Make sure that it has an adjustable thermostat. This feature allows you to get the proper temperature of the hot water just when you need it the most.

Apart from this, you can also look for some additional features like auto-cut off, overheat protection and remote control. Having such features lifts the safety standard and helps you to control the heater easily.

4. Weight

The next important factor for you to consider is the weight of the product. Usually, most of them are a bit heavier than any regular heater. This is because they contain both the tank and the electric heating couplet. This will always increase weight by a fair margin.

However, lightweight products are easy to set up and to install. This will also assure you of the wall mounting option. So try to pick a product that will have easy installation options with lightweight materials. 

5. Dimensions

Before you buy the new Hybrid water Heater, you need to make sure that the product has proper dimensions to fit into the bathroom wall. Well, you may have to measure the space available on the wall and keep a note of it.

Make sure that the dimensions of the heater match with the space available. According to the dimensions, you can install the product either vertically or horizontally.

6. Warranty

The next important thing that you need to consider is the warranty period of the water heater. Most of the products are usually long-lasting and have high-standard materials. Check for the products which will have proper warranty options available for you to choose from.

A higher warranty will mean that your spare parts will be available for long in the market. You will also get proper service for your product from the manufacturer.

7. Efficiency

The UEF of any heater is another factor while you are choosing one. However, efficiency determines how low your electricity bills will be and how much water it can heat.

You can pick the Hybrid Heaters with high ratings which will make sure that it is more efficient. Try to pick a product that has a UEF rating closest to 1. This will make it more efficient to work with.

8. Brand Factor

Choosing just a local Hybrid Heater may seem to be very cost-effective at the first look. But just after a few years when you will have to ask for a professional to repair the parts, you may get fed up with the product.

Try to choose a proper brand for the best Hybrid water Heater. Most of the top-notch brands offer a higher warranty period and better service options for you to consider.

8. Rinnai CHS199100IN Commercial Hybrid Water Heating System

Longer Lifespan

Tank water heaters have a bottom-mounted burner. When the burner is on, it’s blasting at the bottom of this tank. 

With time, this heat causes the tank to degrade and eventually must be replaced because of the wear and tear incurred by the burner’s direct hit.

Thankfully, Rinnai CAS01400TH has never had this issue because it’s a tankless water heater. Since the tankless unit does all the heating, the tank burner doesn’t rinse any of it. 

Additionally, the tank is just for storing hot water. And, of course, the tank burner is not scratching the tank, so it’ll last much longer.

Integrated Temperature Controller

You can simply call it a self-contained water heating system that integrates a temperature controller to provide accurate and stable water heating. 

The controller regulates the electric heating element to maintain the desired temperature, eliminating the need for manual adjustments.

This feature provides greater accuracy and reliability while also reducing energy costs. 

Excellent Performance

We just love this product’s water-heating efficiency. It is so efficient that it can heat 315 gallons of 100 degrees Celsius water in the first hour. 

Even if you were to have a football team showering simultaneously, this hybrid water heater could output 231 gallons of water at 100 degrees Celsius per hour. Most devices can’t keep up that level of performance.
