Pros and Cons of Tankless Water Heaters

When it comes to heating water for home use, the tankless water heater is one of the first products to shake up the industry in decades. On-demand water heaters are skyrocketing in popularity, and are often a more efficient solution for many homeowners. As with any major appliance, however, they come with their own unique set of benefits and drawbacks which should be carefully considered before a purchasing decision is made. When the time comes to replace your hot water heater, consider the pros and cons of doing so with a new tankless model.

Pros

The benefits of using a tankless water heater are numerous. They take up far less space than a traditional storage tank model, are far more energy efficient and cost significantly less to operate than their storage tank brethren. Instead of heating unused water which is then held indefinitely, you’re only using energy to heat what you need at any given moment.

The average estimated lifespan of a tankless model is up to two decades, which also outstrips the ten to thirteen years estimated for a traditional model. Even with the higher up-front cost of a tankless hot water heater, the increased longevity and energy savings often make it a far more economical option in the long run.

Cons

The primary drawback to tankless water heaters will usually only effect large households, which is the fact that more than one point of demand can reduce the effectiveness of the water heater. If someone in the house is showering while others are doing a load of laundry in hot water and running the dishwasher, the output is going to be reduced for everyone in the house. Tankless water heaters may not be the best solution in high-demand households. Additionally, the increased up-front expense over a traditional water heater may be prohibitive for some families, though the cost is often recouped in fairly short order through reduced energy bills.

Working with a licensed and experienced plumber to determine whether or not a tankless water heater is right for your family is the best way to make an informed and accurate assessment.

Size Matters With Water Heaters

When you are considering purchasing a conventional storage type water heater, be sure to choose one with the proper capacity.  A water heater that is too small will not be able to keep up with the demand for hot water and a water heater that is larger than necessary will be inefficient and cost more to operate.

A conventional tank type water heater keeps a full tank of water hot 24 hours a day.  Hot water is always available when needed, but a lot of energy is wasted keeping the water hot when it will not be needed for hours.  Called standby heat loss, the problem is worse the bigger the tank is.  Accordingly, you can minimize standby heat loss by purchasing the smallest sized water heater that will meet the demand.

Experts recommend using the “first hour rating” rather than tank size when selecting a storage type water heater.  The first hour rating is an indication of how much hot water a water heater can supply in one hour starting with a full tank of hot water.

Obviously, the size of the tank will affect the first hour rating but in addition, a water heater that can heat water quickly will have a higher first our rating than a water heater that heats water more slowly. The type of fuel (electric, natural gas, propoane, etc.) and the size of the heating element determine the rate at which a water heater can heat water.

The Department of Energy publishes tables that you can use to estimate your peak hourly demand for hot water.  Once you estimate your peak hourly demand, select a water heater that has a first hour rating within a couple gallons of that amount.
