Plumbing Fixtures and Tankless Water Heaters Buying Guide

Hot water has daily applications in our homes such as bathing, cooking and washing. During the cold season, cold water can become downright unbearable. You don't have to heat water every time you need some warm water. A reliable water heater can supply your home with a steady flow of hot water around the clock.

Do you need a new water heater but you aren't sure which one to purchase? Do you need to replace your existing water heating system? We have prepared this guide for you.

We will start with a brief on how water heaters work.

A water heater is a system that utilizes an energy source to heat water for domestic or industrial use. The most popular sources of energy used for heating water are electricity, solar, and natural gas.

Tank Water Heater vs. Tankless Water Heater

Tank Water Heater

Typically, a water heater comprises a heat source, a storage tank and a series of pipes and valves. A dip tube supplies cold water at the bottom of the reservoir where it gets heated.

For a gas water heater, a chimney may run through the center of the tank so that the escaping exhaust fumes heat the surrounding water. Warm water becomes less dense, rises to the top of the tank, and exits through the heat-out pipe. The piping system in the building supplies the water throughout the household.

Tankless Water Heater

A tankless water heater delivers hot water on-demand. Such systems exhibit high efficiency since there is no energy wasted in keeping the water hot in a reservoir.

When you open a hot water tap, cold water runs into the heating unit and get heated as it passes. It exits the system when hot or warm for immediate use.

Types of Water Heaters

We can classify water heaters by the kind of energy they consume. You can either have a natural gas water heater, electric water heater or a solar water heater.

Let's be more specific by focusing on how these systems function. Your water heater can be one of the following:

• Conventional Storage Tank Water Heater
• Tankless Water Heater
• Condensing Water Heater
• Solar Powered Water Heater
• Heat Pump Water Heater

What Sizes of Water Heaters Can I Choose?

Sizing of hot water heaters depends on the desired temperature ranges at specified flow rates. You must consider the number of house occupants to determine the water tank size that suits your needs.

For tankless water heaters, there is no reservoir consider. The primary factor is the flow rate, which refers to the amount of hot water the system can deliver in a minute.

On-demand gas water heaters usually achieve higher flow rates than tankless electric water heaters. If you want to install a tankless heater, ensure that its flow rate is at least 2.5 gallons of hot water per minute (2.5 GPM). Adjust the variable upwards as per your needs.

When sizing a conventional tank water heater, think about the capacity of the tank. Here are some tank sizes you can consider for your home.

• 30-Gallon capacity
• 40-Gallon capacity
• 50-Gallon capacity
• 80-Gallon capacity

Your household hot water requirements will also come into play. Getting your tank capacity right can offer substantial energy savings. A smaller tank than required means multiple cycles of heating per day while an overly large reservoir means heating more water than needed.

What Features Should I Look for in a Water Heater?

Product features impact the usefulness of an item, though some are aesthetic. Here is what to look out for when choosing a water heater.

Digital Display

Water heaters with digital displays are more straightforward to monitor. Depending on the model, you can read and regulate the water temperature on a panel. An advanced system may also report errors in case the heater develops a problem.

Some water heaters will also let you customize their operation. For instance, you can set the heat pump mode if you will be away to make the system more energy efficient.

Glass-Lined Tanks

Glass resists corrosion. Therefore, rust won't be part of your concerns when you have a glass-lined tank.

Drain Valve

Mounted at the base of the tank, drain valves, are outlets for excess water. They are usually brass or plastic in most systems. Our advice is you go for brass because its quality is superior to most other materials.

Anti-Scale Devices

Water heaters may offer anti-scale devices to prevent deposits from settling on the heating appliances. They may also soften the water and convert some mineral elements to a filterable state.

Warranty

One way of predicting the lifespan of a product is its warranty. You can expect a product to serve you well if the manufacturer offers a considerable warranty period. Find out if the coverage extends to the whole unit or some specified water heater parts.

Things to Consider When Buying a Water Heater

Vital considerations when purchasing a hot water heater include:

• Tank Size: Tank capacity should match your demand for hot water.
• Power Source: A water heater can only be useful if you can access and afford the relevant energy source.
• Efficiency: Get yourself a water heater marked Energy Star for high efficiency.
• Budget: We can help you to select a unit that balances your needs with your budget.
