the ideal home water heater being installed.

Choosing the right water heater for your home is the most essential step for ensuring the efficiency and longevity of this indispensable household appliance. Most of the issues homeowners have with their water heaters come from mistakes when buying the unit, notes Schambs Property Management team .

Unlike other water heater problems – most of which can be fixed – there is nothing you can do to correct the mistake of buying the wrong water heater for your home. The only two ways to deal with the problem are to keep living with the consequences of your error or buy another water heater.

That is why it is vital to research before buying and installing a new water heater for your home. Your home has unique hot water needs, and not every water heater can meet those needs. That is why, before you pull out your card to pay for a water heater, you must ensure it is the right one for your home.

5 tips to help you find the ideal water heater for your home

Water heater capacity or size

This is the most vital factor when selecting a water heater. A low-capacity water heater will see you running out of hot water, while one with excess capacity will increase energy costs. How do you determine the right size of water heater for your home? The US Department of Energy recommends a 50-60-gallon storage tank for a property of 2-3 people. For larger homes of 3-4 persons, a medium 80-gallon storage tank should be enough. A large tank is the best option if you have more than 4 people in your home. For tankless water heaters, look at the gallons-per-minute ratings and how many gallons of hot water the water heater can deliver within a minute.

The type of water heater

The second most important factor is the type of water heater. There are five types of water heaters, but only two are relevant for this post: conventional storage water heaters and tankless (or on-demand water) heaters. Tankless water heaters don’t have storage tanks but deliver hot water at a steady rate whenever needed. Storage water heaters have a large tank where they store heated water. From an energy-efficiency standpoint, tankless water heaters are better. However, they cost more. Storage water heaters are cheaper but have a shorter lifespan of 10-15 years compared to 20 years for tankless water heaters.

Type, availability and cost of fuel

The type of fuel your water heater runs on affects its size, operating cost and efficiency. Electricity is the most common way water heaters are powered. Electricity is widely available and works with every kind of water heater. Propane and natural gas are other popular options; they are available in most parts of the USA and are less expensive than electricity. Propane and natural gas are also very efficient. Depending on where you live, solar energy is an option worth exploring. Homeowners in the Southwest USA should seriously consider switching to a solar-powered water heater.

Water heater cost

This is not just the cost of purchasing the water heater but the cost of owning it. Storage water heaters have the lowest upfront costs, but maintenance cost rises as the reservoir ages. It costs more to buy a tankless water heater, but the operating cost is lower. Solar water heaters have the highest upfront cost, but this cost is easily recouped since you will not be spending money on electricity or gas. The type of fuel your water heater uses also plays a part in its operating costs. Gas water heaters are more affordable than electric water heaters. Solar water heaters have the overall lowest operating cost.

Water heater maintenance

Storage water heaters suffer from leaks/corrosion and need occasional descaling. If the water in your area is hard, the rate of scaling will be higher, and you will have to drain and flush the tank more often. Scaling affects the efficiency and longevity of your water heater. In addition to flushing the tank yearly, you need to replace the anode rod and relief valves in a storage water heater. But despite how much work it is to maintain a storage water heater, it is easier than maintaining a tankless water heater. Unlike storage water heaters, caring for a tankless water heater is complex.

To conclude, unless you are an expert, it is hard to make the right decision on the best water heater for your home all by yourself. That is why you should consider speaking with a professional plumber as you make these decisions. Remember that if you get it wrong, you will have to live with the consequences of your choices for a very long time.

Choosing the Right Capacity for Your New Water Heater Installation

Are you about to replace the old water heater in your home? If yes, do you plan to install a new unit similar to the old one, or do you plan to upgrade the water heater? There is no better time to review your home’s hot water needs than when you are about to buy a new water heater.

The two things you want to consider when buying a new water heater are how much hot water your home uses and the water heater’s energy efficiency. As Pentwell Properties say you want to buy the right size water heater that meets the family’s hot water needs and also helps you save energy.

How do you do that? The steps for sizing a new water heater for your home depend on the type of water heater you want to install: a tankless water heater or a storage-type water heart. Below are the explanations on how to size these two water heaters.

Sizing a new water heater

How to size a storage water heater

Use the unit’s First Hour Rating (FHR) to size a storage water heater. That is the number of gallons of hot water the water heater can supply per hour when it starts with a full tank. The FHR depends on the tank capacity, the source of heat, and the size of the burner.

You can usually find the FHR for the unit in the top left corner of the EnergyGuide label listed as capacity (first-hour rating). Information about the FHR can also be found in the product literature. Look for a water heater with FHR above your home’s peak hour demand.

The second thing you must know to correctly size a storage water heater is your home’s Peak Hour Demand. That is the number of gallons of hot water the home uses during the peak hour of use. That depends on the number of people in the house. How do you calculate peak hour demand?

On average, each member of your household uses around 12 gallons of water in the shower. Multiply the number of people in the home by 12 (the number of gallons used per person). That is the number of gallons of hot water the water heater must supply during peak hours.

If there are five people in your home, the water heater must be able to supply 60 gallons of hot water during peak hours. That means the water heater must have a first-hour rating above 60 gallons. The peak hour demand must always be lower than the water heater’s FHR.

The water heater’s FHR also helps you determine its yearly cost of operation and estimated yearly energy consumption. This information can be obtained from the EnergyGuide Label, and it is different for gas and oil-powered water heaters versus electricity-powered units.

Tankless water heaters do not store water but supply hot water on demand. Sizing these types of water heaters is a bit more complicated.

How to size a tankless water heater

Tankless water heaters do not store water but supply hot water on demand. Sizing these types of water heaters is a bit more complicated. Tankless water heaters are rated according to the maximum temperature rise possible at a given flow rate.

To size a tankless water heater, you must know the flow rate for the different water devices in the home. Depending on whether you are installing a whole-house water heater or the unit is for a specific fixture, you may now determine the required temperature rise at that flow rate.

As a first step, list all the water devices in the home. Add up the flow rates for all the water-utilizing appliances and plumbing fixtures in the house, or add up the flow rates for all water devices you expect to use simultaneously, such as a faucet and showerhead.

If you do not know the flow rate for a device, you can calculate it by holding a pan or bucket under that device. Run the water for a minute and calculate how much water has flowed into the pan or bucket. Typically, this will be between 0.75 gallons and 2.5 gallons per minute.

To calculate the desired temperature rise for the unit, deduct the incoming water temperature from the required output temperature for the water heater. You may assume an incoming water temperature of 50ºF (10ºC) can hold a thermometer under a cold-water faucet to get the temperature reading.

With these details – the flow rate for your home and the required temperature rise for your new water heater – you now have an objective measure for deciding if a tankless water heater is suitable for your home.

In Conclusion

Remember that buying a new water heater is not just about choosing the proper unit. There are other essential considerations, as well as the process of installing the water heater. To get the most out of your new water heater, you may want to talk to a professional before you make any decisions.
