A tankless water heater, also referred to as an instantaneous or demand-type water heater, provides hot water only as it is needed. It is space-saving, energy-efficient, and saves you money.

Tankless water heaters offer a constant supply of hot water without using a storage tank. They don’t produce the standby losses expected with storage water heaters.

Cold water travels through the unit and is heated using electricity or gas to provide a hot water supply that lasts until you turn the tap off.

If a tanked water heater doesn’t work for your home, a tankless water heater makes the best alternative. It’s space-saving since there’s no bulky water tank, and you don’t have to wait for the water to heat up.

The water is heated almost immediately when you turn your faucet on.

A tankless water heater makes an excellent option if you are tired of running out of hot water when doing home chores. It will never run out of hot water.

However, when shopping for one, you need to put your home size and the water usage habits of your family into consideration.

If you usually run several appliances or showers at a go, it overburdens your heater, and your water might not heat up to the required temperatures.

Why Should You Purchase a Tankless Water Heater for Your Large Family?

You’ll enjoy several benefits of switching to a tankless water heater. They include:

  • Long-term Energy and Cost Savings

The main advantage of getting a tankless water heater for your home is that these units are energy efficient and will help you save you a lot of money in the long term.

A water heater with a tank expends energy throughout to maintain the temperature of a 40-50 gallons water supply. It’s the only way to ensure that the water is hot when needed.

Tankless water heaters provide hot water on demand and don’t maintain a water supply.

By only heating your water when you need it, the heater does not experience standby heat loss, which usually happens when heat escapes the storage tank necessitating constant heating.

Therefore, if you have a large family, you’ll save a lot on energy with a tankless water heater. These heaters save between 8% and 50% more power than tank-style models.

If your family utilizes a lot of hot water, about 86 GPD, you’ll save 8% to 14% on energy.

In addition, if you install a tankless water heater at each outlet instead of a centralized system for the whole house, you’ll save even more – 27% to 50%.

  • Takes Up Less Space

If you have a large family, you already know how valuable space is. The more space-saving the water heater is, the better.

Tankless water systems take up less space compared to tank-style models. Some models can even be mounted on the wall and fit in most closets.

  • Provide Unlimited Supply of Hot Water

With a large family, you need water that offers an unlimited water supply. Just imagine where you’ve come home from hiking, and everyone needs to take a shower.

With a tank-style water heater, chances are, hot water will run out before everyone has taken a shower.

If you have a tankless model, you’ll never find yourself in that situation.

Every tankless water heater has a maximum flow rate. If your water usage is below the maximum flow rate, you’ll get an endless hot water supply.

  • Lower Risks of Leaks

One of the biggest drawbacks of tank-style heaters is that over time, hard water minerals buildup in the tank leads to corrosion and eventually leaks.

Tankless models don’t have tanks, thus minimizing the risk of leaks or flooding.

Does this mean that they are immune to problems? Not at all, these units can run issues that result in leaking, but it’s really hard to come across major leak floods.

  • Durable

Unlike tank-style water heaters that last up to 10 years, tankless models usually last over 20 years.

If you already own a home, investing in a tankless water heater is a smart move. It’ll save you from replacements for a very long time.


If you have a large family, investing in a tankless water heater will save you money. These units are energy-efficient, provide unlimited access to hot water, never leak, and don’t add harmful metals to your water.

Tankless models last for a very long time, meaning that once you have one in place, you won’t have to worry about replacements.
