Do tankless water heaters increase electric bill?

Yes, tankless water heaters do increase your electric bill. While they require less energy to heat the water and are usually more efficient than traditional tank water heaters, their electric draw is often higher.

This is largely because they are designed to produce hot water on demand, which means they must constantly draw electricity when they’re in use. Tankless water heaters usually require high wattage and may use more energy than traditional ones, depending on the flow rate; the higher the rate, the more energy is consumed.

In addition, they typically have a minimum electric load (often 20 amps), which is more than standard water heaters. In some cases, upgrading an electric service might be necessary to accommodate this.

What size tankless water heater do I need for a family of 4?

The size of tankless water heater you will need for a family of four will depend on your hot water usage and preferences. Generally, a family of four would need between a 6-7. 5 GPM (gallons per minute) tankless water heater, depending on the flow rate for the showerheads, faucets and other fixtures in your home.

For example, if you have low-flow fixtures, you may be able to get away with a 6 GPM tankless water heater. However, if you have full flow fixtures and use a lot of hot water, it would be best to get a tankless water heater with a higher GPM rating.

Additionally, you should consider how far away the tankless water heater is to the fixtures it will be serving, as the farther the heater is, the more likely you are to need a higher GPM rating. It is also important to factor in the incoming water temperature in your area, as colder water temperatures will require a larger capacity tankless water heater in order to perform adequately.

Ultimately, you should consult with a licensed plumber who can advise you on the best size tankless water heater for your family of four based on a variety of different factors.

To keep the unit running efficiently and at the optimal temperature, however, it is important to use water-save features and set the temperature control on the heater to an appropriate setting for the needs of your household.

Will a tankless water heater lower my gas bill?

A tankless water heater can potentially help you lower your gas bill. Tankless water heaters heat water on demand, so you will only be using energy to heat water as you need it, instead of using energy to keep a tank of hot water constant.

If you use a lot of hot water and/or have a large family, you may end up using more energy overall, but this would still be less than a traditional tank model. Furthermore, many tankless water heaters come with energy efficiency ratings, so you can find one that fits your needs while shifting your energy consumption into a more efficient model.

While tankless water heaters are often more expensive when compared to tank models, the difference can be made up in gas bill reductions in the long run, making it a more cost effective option in the long run.

Is it worth it to go tankless?

When deciding whether or not it’s worth it to go tankless, the cost savings of switching to a tankless system should be taken into consideration. Going tankless is beneficial in helping to save energy and money on your monthly water bills.

Tankless water heaters can heat water on an as-needed basis, meaning they don’t continually run like traditional water heaters. This means that you won’t waste energy or money on heating and reheating the same water.

Tankless water heaters also use less energy, and when compared with traditional hot water systems, tankless systems can save up to 30% on your energy bill each year. Additionally, some tankless water heaters provide instant and on-demand hot water which can help to conserve water.

The cost and complexity of installation of a tankless system should also be taken into consideration. Tankless water heaters require a larger up-front investment than traditional hot water systems and generally require more complex installation.
