If you’ve ever wanted endless hot water at the turn of a faucet, a tankless water heater might be the perfect solution. Unlike traditional water heaters, tankless water heaters, also known as on-demand water heaters, don’t store hot water in a tank. They heat water on demand, providing a more efficient and convenient way to get hot water.
Let’s look into how these systems work, their benefits, and what to expect from a tankless water heater installation.
What is a Tankless Water Heater?
A tankless water heater system heats water as it passes through the unit, rather than storing hot water in a tank. This means you get hot water only when you need it. Here’s how it works in simple terms:
- When you turn on the hot water tap, cold water enters the unit.
- A gas burner or electric element quickly heats the water as it moves through the system.
- The hot water is then delivered directly to your faucet or showerhead.
Tankless Water Heaters: Gas
When choosing a tankless system, we work with gas models only. These use a gas burner to heat the water and require a steady gas supply. They tend to heat water faster and are ideal for larger households.
Choosing between gas or electric tankless water heaters (which we don’t service) will depend on your home’s setup, available fuel types, and personal preferences.
How a Tankless Water Heater Heats Water on Demand
So, how does a tankless hot water heater heat water so quickly? It’s all about the advanced heating technology inside the unit. The key difference between traditional water heaters and tankless ones is that there’s no storage tank.
When you open a hot water tap, the water flows through the system. Sensors detect the water flow, triggering the heating element (gas or electric). The water is then heated to the desired temperature as it passes through the heat exchanger and delivered straight to your tap. This process ensures you’re never waiting around for hot water!
Pros and Cons of Tankless Water Heaters
Like any appliance, there are pros and cons to using a tankless water heater. Here’s what to consider:
Pros
- Energy efficiency: Since there’s no need to keep water hot in a tank, a demand water heater uses less energy, lowering your operating costs.
- Longer lifespan: Tankless systems generally last longer than traditional tanks, often up to 20 years with proper maintenance.
- Endless hot water: You won’t run out of hot water, no matter how long your shower is!
- Space-saving: Tankless water heaters are compact and can be installed in smaller spaces.
Cons
- Higher upfront cost: The cost of a tankless water heater can be higher than a traditional tank model.
- Installation complexity: Tankless water heater installation requires a professional and may involve upgrades to your home’s electrical or gas supply.
- Inconsistent temperature: In some cases, you may experience temperature fluctuations if multiple taps are using hot water simultaneously.
Cost of a Tankless Water Heater
The cost of tankless water heater installation can vary based on the model and your home’s requirements. On average, you can expect to pay anywhere from $1,500 to $3,000, including installation.
Keep in mind that while the initial cost may be higher, the long-term savings in energy costs and the longer lifespan of a tankless system can make it a worthwhile investment. Plus, you’ll enjoy lower operating costs compared to a traditional water heater.
Tankless Water Heater Maintenance
Just like any other appliance, regular tankless water heater maintenance is essential to keep the system running smoothly. Here are a few tips:
- Descale the system: Minerals from hard water can build up in the heat exchanger, reducing efficiency. Descaling every year or so can prevent this.
- Check filters: Ensure the water inlet screen is clean and free from debris.
- Inspect for leaks: Occasionally check for any leaks around the unit, particularly in the pipes and connections.
A professional technician can perform these tasks during your regular water heater maintenance checks.
What to Expect During Tankless Water Heater Installation
Tankless water heater installation is more complex than simply swapping out an old tank. Depending on whether you choose a gas or electric model, your installer may need to upgrade your home’s gas supply or electrical panel to handle the new system.
Here’s a general overview of the installation process:
- Assessment: A professional installer will assess your home’s current plumbing and energy needs.
- Upgrades (if needed): Your installer may need to upgrade the gas supply, install new venting, or make changes to your electrical system.
- Installation: The tankless water heater is mounted on the wall and connected to your home’s water and energy supply.
- Testing: Once everything is connected, the installer will test the system to ensure it’s working properly.
Hiring a licensed professional is key to ensuring your system is installed correctly and safely.
Is a Tankless Water Heater Right for You?
Tankless water heaters are a fantastic option for anyone looking for a more energy-efficient and space-saving way to heat water. They offer nearly instant hot water, a longer lifespan, and lower operating costs over time.
However, they do come with a higher upfront cost and more complex installation requirements. If you’re not sure whether a tankless system is right for your home, it’s always a good idea to consult a professional. They can assess your water usage, fuel types, and home setup to recommend the best option.
The Bottom Line
A tankless water heater system can be a game-changer for your home, providing endless hot water while saving space and energy. Whether you choose a gas or electric tankless water heater, proper installation and maintenance will ensure you get the most out of your system for years to come.
