Benefits of an Instant Hot Water System
Instant hot water systems offer quick comfort and save energy. They heat water on demand, reducing waste and cutting utility bills.
Immediate hot water access
Instant hot water systems provide hot water right when you need it. These systems heat water as it flows through, giving you endless hot water. You don’t have to wait for a tank to heat up.
This saves time and cuts energy waste from keeping a big tank hot all day.
Electric and gas models offer quick hot water access. They work well in homes, apartments, and businesses. Users enjoy hot showers without running out of hot water. These systems also take up less space than traditional water heaters.
Energy efficiency
Instant hot water systems save energy by heating water only when needed. They also eliminate standby heat loss from storage tanks, which means lower utility bills and less energy waste. Electric tankless heaters, backed by ENERGY STAR, are especially efficient.
They use power only during active use, reducing overall energy demand.
These systems also help the environment. By lowering energy use, they decrease greenhouse gas emissions, making them a smart choice for eco-conscious homeowners. The energy savings add up over time, making instant hot water systems a wise investment for wallets and the planet.
Space-saving design
Instant hot water systems save space in homes and buildings. These compact units don’t need large storage tanks, freeing up room for other uses. You can install them in tight spots like closets or under sinks.
Their small size makes them perfect for apartments, tiny houses, or any place where space matters.
These systems hang on walls or fit in small cabinets. They heat water as needed, so no bulky tank is required. This design allows for more flexible placement options, and you gain extra floor space and storage areas in your home.
The sleek look of these units also adds a modern touch to any room.
Types of Instant Hot Water System
Instant hot water systems come in three main types. Each type offers unique benefits for different home setups and user needs.
Electric Tankless Water Heaters
Electric tankless water heaters offer on-demand hot water without a storage tank. These units heat water as it flows through using electric coils, saving space and energy compared to traditional tanks.
Airthereal makes several models, ranging from 8 kW to 27 kW. Prices start at $159.99 for the 8-kW version and go up to $299.99 for the 27-kW model.
These heaters work well for homes with 240-volt electrical systems. The right size depends on how much hot water you need at once. Larger units can handle multiple faucets or appliances at the same time.
Electric tankless heaters are easy to install and maintain. They also last longer than tank-style water heaters.
Gas Tankless Water Heaters
Gas tankless water heaters offer on-demand hot water without a storage tank. These units heat water as it flows through, using natural gas or propane. They save space and can be more energy-efficient than traditional tanks.
But there’s a catch. These heaters emit twice as much unburnt methane as standard gas storage models. This matters because methane has 86 times more warming power than carbon dioxide over 20 years.
Despite their benefits, gas tankless heaters make up only 2% of U.S. gas water heater sales. Their higher upfront cost and installation needs may slow adoption. Users must also consider flow rate needs and gas line capacity.
While they can cut energy use, their methane emissions raise questions about their environmental impact.
Point of Use Water Heaters
Point-of-use (POU) water heaters offer quick hot water access right where you need it. These compact units fit under sinks or in closets near fixtures. POU heaters store 2.5 to 20 gallons of water and heat it on demand.
According to the U.S. Department of Energy, they cut energy use by up to 50% at each outlet.
POU systems cost $400 to $800 to install. They last 10-15 years for tank models and up to 25 years for tankless versions. These units save space and energy while giving instant hot water.
For homes with spread-out fixtures, POU heaters offer a smart solution.
Key Considerations When Choosing a System
Choosing the right instant hot water system depends on your needs and home setup. Learn about flow rates, energy sources, and installation requirements to make the best choice.
Flow rate needs
Flow rate is key when picking an instant hot water system. It measures how much hot water the unit can provide at once. Most homes need 2-5 gallons per minute (GPM). Showers use about 2.1 GPM, while dishwashers need 1.5 GPM.
Gas units offer higher flow rates, up to 5 GPM, than electric models at 2-5 GPM.
Your home’s size and habits affect flow rate needs. Large families or homes with multiple bathrooms require higher GPM. Consider peak usage times, like mornings when several people shower.
Match the system’s flow rate to your household’s demands for the best performance.
Energy source availability
Energy source availability is key in choosing an instant hot water system. Your home’s current setup affects your options. Homes with natural gas lines can use gas-powered units.
These often heat water faster than electric models. Homes without gas access may need to stick with electric systems. Some areas offer propane as an alternative fuel source.
Cost and efficiency matter, too. Electric units are often cheaper upfront but may cost more to run. Gas systems can be pricier to install but usually have lower operating costs. Solar-powered options work well in sunny climates and can save money in the long term.
Fuel oil and geothermal energy are less common but might suit certain homes. Pick a system that matches your home’s energy sources and budget needs.
Installation requirements
Installing instant hot water systems needs care and skill. A qualified contractor should handle the job to meet local codes and safety rules. They’ll check your home’s power supply, water pressure, and venting needs.
Proper ventilation is key to removing exhaust gases from gas units. Electric models may need upgraded wiring to handle the high-power draw.
The installer will also pick the right spot for your unit. It should be close to where you use hot water most, reducing wait times and heat loss. They’ll connect water lines, install shut-off valves, and set up the control panel.
Regular upkeep based on the manual helps keep your system running well for years.
Summary
Instant hot water systems offer comfort and savings. They heat water on demand, cutting energy use and costs. These compact units fit in small spaces, making them great for any home.
Choose the right system based on your needs and energy source. With proper care, these systems provide years of reliable hot water service.
FAQs
1. What is an instant hot water system?
An instant hot water system, a tankless water heater, heats water on demand without storing it. It uses a heat exchanger to warm water quickly as it flows through the unit.
2. How do electric instant water heaters work?
Electric instant water heaters use heating elements to warm water rapidly. When you turn on a hot water tap, cold water enters the unit and is heated instantly by electric coils.
3. Is an instant hot water system energy-efficient?
Yes, instant hot water systems are energy-efficient. They only heat water when needed, reducing energy waste. This can lead to lower energy bills compared to traditional storage water heaters.
4. Can instant water heaters supply enough hot water for a whole house?
Larger instant water heaters can supply hot water for an entire home. The key is choosing a unit with enough British Thermal Units (BTUs) to meet your household’s peak demand.
5. Does an instant hot water system require special installation?
Installing an instant hot water system often requires a professional plumber. Depending on the model, these units may need upgraded electrical circuits or gas lines.
6. How does an instant hot water system differ from whole-house systems?
