Things to Consider When Buying a Tankless Water Heater

Nowadays, everyone is energy-conscious; this means when purchasing any electrical device, energy consumption is often their top priority. With different models equipped with great features, there are several things you will need to consider when purchasing a tankless water heater that will best meet your need. Some of the aspect you should consider when buying a tankless water heater include;

· Size

It is highly essential to purchase a tankless water heater that will best suit your need and to do this, you will have to carry out a little research. First and foremost, you will have to consider adding up the flow rate. Usually, this is the amount of hot water you will use at any given time; ensure that it is best to measure it in gallons per minute. This will include your dishwashers, any washer, showers, sinks, and tubs that you will be running at any given moment. You might consider Google searching the appliances you use along with the shower heads to provide the appropriate idea of your flow rate.

You will then add them up, and the resulting number should be the flow rate of your tankless water heater. Note it down before purchasing it from any shop. When you fail to find a tankless water heater that does not match your flow rate, then the probability of your home requiring double units will be high. In addition to that, you will need to consider the temperature rise. Usually, the amount of temperature of your tap water will rise before coming out of the faucet; this is as a result of the tankless water heater. Always look for temperature rise that will be best for you; usually, 5 gallons of water will get heat per minute when using a gas unit and two gallons per minute for the electric unit.

· Gas or electric unit

You might consider purchasing a gas or electric tankless water heater unit. Each design features a unique benefit. For instance, tankless water heaters operate using large gas lines when compared to conventional water heaters. As a result, it makes the installation process much more expensive when compared to an electric unit.

A gas tankless water heater unit tends to heat water faster, allowing them to supply higher water pressure. However, their pilot lights are always on even when you do not require hot water. This makes them operate on more energy when compared to their counterparts, the electric units. As an individual who prefer gas units over electric units, you should consider looking for those with intermittent ignition device. This device aids in turning the pilot light off and on whenever you require hot water.

· Your household

The size of your household tends to have a significant impact on the type and the size of your tankless water heater. Despite the fact that a tankless water heater will offer you endless hot water for a single tap, it will not supply hot water to your sinks, washers, as well as other showers at the same time. If you have several valves that operate on the hot water at the same time, it will be best for you to install two or more tankless heaters to help you keep up with the demand. Furthermore, the United States Department of Energy states that homes equipped with water heaters on each hot water outlet tend to save more energy when the family uses over 86 gallons of hot water in a day.

· Energy efficiency

Energy efficiency should top your priority when looking for a tankless water heater. Despite the fact that the primary goal of tankless water heater is to save energy, it is best for you to pay attention still when making a purchase. You should note that whenever the efficiency and saving of a system decrease, the need for hot water in the households increases.

Tankless water heaters tend to use the Energy Factor (EF) rating in measuring the overall efficiency of a water heater. Usually, the EF is determined by useful energy that comes from the water heater. The number is then divided by the energy (either gas or electricity) that goes into the water heater for it to heat your water.

EF rating is then based on the amount of hot water being produced by one unit of fuel consumed. Therefore, the higher the EF rating, then the more efficient your water heater is. However, when it comes to operating costs, tankless water heaters with high EF ratings tend to use more electricity when compared to gas units. With gas being an affordable fuel source when compared to electricity, gas units will deliver lower annual operating costs.

· Warranty

Usually, warranties tend to differ from one manufacturer to another and from one model to another. Most of the manufacturers require you to register the tankless water heaters for it to be professionally installed and have an available warranty cover. When selecting the best tankless water heater, comparing warranties is becomes vital. Whenever the manufacturer stands behind their products along with a warranty time frame that is reasonable, it shows a great indication that has a firm believes in their product in terms of quality and reliability.
