What to Look for in a Water Heater

The water heating industry has gone a long way, with improved models and a wide range of high-tech customization choices available to anybody shopping to replace an aging system.

Bosch, Rinnai, GE, Ruud, Takagi, and Rheem manufacture a wide variety of water heaters, including conventional gas tanks and tankless electric models.

The Rheem Manufacturing Company is well recognized as the premier manufacturer of high-quality and energy-efficient water heaters across various product lines.

Customers can rest assured knowing that the water heaters they buy from them are of the highest quality since they are made with care and put through rigorous quality assurance testing.

There are a lot of factors to think about while picking between electricity, gas, or hybrid. Finding the right water heater may be challenging, but we hope our reviews and shopping advice will help. Gas heaters are less expensive than electric water heaters, yet they use more energy. Gas heaters are also known for their quick recovery times.

When picking which water heater to replace the current one, it’s also essential to consider the current one the client uses. Many buyers replace their old heater of the same kind rather than transition from gas to electric since this might need extra work and cost more money.

When you’ve decided on a water heater in Fort Lauderdale for you and are ready to install a new one, this guide will help you choose the perfect one for your household. 

What are the different types of water heaters?

Tank-Storage Water Heater

Tank water heaters are in most homes where the water is heated using a storage tank. Water is heated and held in an insulated tank until it is required. It is released via a pipe on top of the water heater, as the name indicates.

There is also a pressure and temperature relief valve that will release any built-up pressure or heat.

While natural-gas water heaters cost more upfront, they save money in the long term due to their lower energy consumption and lower operating costs (by nearly half).

Tankless Water Heater

Tankless water heaters don’t store water but instead, heat it instantly using coils whenever you need it. Their energy efficiency is superior to that of a storage tank.

Still, they can only provide a small amount of hot water every minute (about 3.5 gallons, depending on intake water temperatures).

It’s recommended for those who don’t regularly use water for many purposes, such as taking a shower and starting the dishwasher.

Natural gas is ideal for tankless versions since it doesn’t need a pricey update to the home’s electrical capacity to power the unit.

Water Heater With a Heat Pump (Hybrid)

Hybrid heat pump water heaters are effective in transferring heat from the air to the water below. Compared to regular electric water heaters, they save energy consumption by over 60%.

While they are more expensive than electric-only ones, their setup time and payback period are about the same. But they have to be kept in a room where the temperature is between 40 and 90 degrees Fahrenheit for optimal performance.

And since the heat pump is on top, a hybrid water heater requires as much as 7 feet of space from floor to ceiling. To collect enough heat from the air, you’ll need an area of up to one thousand cubic feet that isn’t air-conditioned and a drain nearby to empty the condensate.

What Size Water Heater Tank Does My Household Need?

Water heater manufacturers often categorize storage tank water heaters according to the volume of water they can provide. It’s crucial to calculate the typical daily need for hot water in your home so that you can stock up accordingly. A bigger tank is required for a more sizable household unless a tankless model is used.

Another factor to consider is the recovery rate or the amount of water that a storage tank can heat while replenishing the tank. A larger recovery rate is required when more hot water is used often. You may need a larger water heater if you often run the dishwasher or the washing machine.

If a tank water heater is what you’re after, consider these guidelines as a starting point for determining the correct size.

Where Should I Put My Water Heater Tank?

There are other choices if a conventional water heater is too large for your home. All three of these choices are equally effective and adaptable to electric, natural gas, or propane systems. 

Low Boy Height and Water Heater Cabinet Depth Requirements

These water heaters come in gas and electric varieties and are narrower and shorter than standard ones. Water capacity is the same as their bigger counterparts but may be placed in tighter quarters beneath cabinets and crawlspaces. Lowboys have a capacity of up to 50 gallons of water and may be as tall as 30 inches.

Having Enough Room for a Tall Water Heater

Both gas and electric tall water heaters are available, with capacities of up to 100 gallons. Their heights vary from 50 to 76 inches. They work well in low-ceilinged areas such as basements and garages.

Remember that hybrid water heaters have unique installation requirements and should be installed in a larger-than-usual area, so be sure to read the instructions provided by the manufacturer before making your final decision.

We’ve made selecting a water heater simple by dividing them into two groups: electric and gas.
