Power

You must decide whether you want to go for a large electric water heater or a gas water heater. Moreover, you must understand that the electric tankless water heater might be cost-effective initially, but it might not be able to have a temperature rise just the way you want.

However, compared to the electric tankless water heater, the gas water heaters are a lot better in terms of the temperature rise. Still, these water heaters are also not the most affordable option.
But we would say that the gas tankless water heaters are a lot more energy-efficient and have a quick and efficient mechanism.

Whether you plan to install the water heater indoors or outdoor, you must consider the ample space available for the installation. Most people prefer installing a tankless water heater in their bathrooms, which can be a great choice.

However, you must consider that the large electric hot water heaters for a big family are comparatively smaller in size than the gas water heater. You must also understand that the electric tankless water heater for a family of 4, 5 or 6 must have a flow rate that is highly compelling to meet the needs of a large family.

Energy Efficiency

Moreover, energy efficiency plays a vital role in long-term saving costs and better use of the water heater.

Flow Rate

The most vital feature of the best tankless heater for a large family is the floret. You can not settle for a tankless water heater with a flow rate of 3 or 4 gallons per minute. You must find out the water heater with a minimum flow rate of 5 to 7 gallons per minute.

FAQs

How much will the best tankless water heater cost?

When considering the average cost of an electric tankless water heater, it will be between $500 to $1000. However, when looking for a water heater that can serve a large family, it might cost a little bit around $1000 or more, including the installation process.

However, for a gas tankless water heater, you might need to have a budget of up to $2,500. Also, for a unit that can serve a family with up to 4, 5, or 6 people, you must find a water heater with a flow rate of at least 9 gallons per minute.

But in the traditional heaters, you need to wait at least 30 minutes before you get the hot water in the fixture.
