Hot water is essential for daily activities like showering and washing dishes, and choosing the right water heater can impact your home’s comfort, energy use, and bills.
On-demand hot water heaters, also known as tankless water heaters, are becoming a popular choice over traditional tank models. They provide instant hot water, save energy, and last longer. Whether you’re considering an on-demand hot water heater electric or on-demand hot water heater propane, these systems offer a modern, efficient solution.
In this guide, we’ll explain how they work, explore their pros and cons, and answer common questions like, “How long does a hot water take to heat up?” Plus, we’ll introduce Econoair HVAC Services, your trusted partner for expert installation and maintenance.
Unlike traditional water heaters that store and heat a large tank of water, on-demand hot water heaters only heat water when it’s needed. These systems are designed to supply hot water instantly whenever a faucet is turned on, eliminating the need for a storage tank. Water is heated as it flows through the unit by either a gas burner or an electric element. This offers a continuous flow of hot water without the wait or worry of running out.
An on-demand water heater operates differently from a conventional tank model. Here’s a breakdown of how it works:
Cold Water Intake: When you turn on a hot water tap, cold water travels through a pipe into the tankless unit.
Heating Element Activation: Either a gas burner or an electric heating element is activated to heat the water instantly as it flows through the unit.
Hot Water Supply: The system delivers hot water to the faucet or appliance, ensuring a constant supply without needing to wait for a tank to refill.
System Shutdown: Once the water flow stops, the heating element or burner shuts down, preventing unnecessary energy use.
With this design, there’s no need for a large storage tank, and energy is only used when you need hot water, leading to considerable savings.
While on-demand water heaters offer numerous benefits, there are a few potential drawbacks to keep in mind:
Higher Upfront Costs
The initial purchase price of a tankless water heater is generally higher than that of a traditional water heater. Additionally, installation costs can be more expensive, especially if your home requires upgrades to accommodate the new system (e.g., gas line installation or electrical upgrades). However, the long-term energy savings often make up for the higher upfront investment.
Limited Flow Rate
Depending on the size of your tankless unit, it may have difficulty providing hot water to multiple fixtures simultaneously. For example, if you’re running a shower, dishwasher, and washing machine at the same time, a single unit may struggle to meet demand. To avoid this issue, larger households might consider installing multiple units or choosing a system designed to handle higher flow rates.
Delayed Hot Water
Because on-demand heaters don’t store hot water, there can be a slight delay in receiving hot water as the system heats it on demand. This issue can often be mitigated by installing a recirculation system, which minimizes the wait time.
The benefits of installing an on-demand hot water heater are significant, especially if you want an energy-efficient, space-saving, and eco-friendly option. Here’s a quick look at the advantages:
Energy Efficiency & Lower Bills: On-demand systems heat water only when needed, avoiding standby heat loss. They can be up to 34% more efficient than traditional heaters, leading to lower utility costs.
Unlimited Hot Water: Unlike traditional tanks, these systems provide continuous hot water, so you never run out, even with long showers or multiple appliances running.
Compact Design: Tankless units are small and wall-mounted, saving floor space and fitting easily into tight areas.
Longer Lifespan: Tankless water heaters last up to 20 years, outlasting conventional models and reducing the need for frequent replacements.
Eco-Friendly: They conserve both energy and water, reducing waste by providing hot water instantly without long wait times.
Whether an on-demand hot water heater is right for you depends on several factors, including your household size, water usage patterns, and budget. If energy efficiency, unlimited hot water, and long-term savings are priorities, a tankless system is a smart choice. Additionally, if you’re looking to free up space and reduce your environmental footprint, switching to an on-demand water heater offers significant benefits.

To keep your on-demand water heater in top condition, regular maintenance is key. Here are some tips:
Descale Regularly
Hard water can cause mineral buildup in the unit, reducing efficiency. Econoair recommends descaling your water heater annually to prevent clogs and extend its lifespan.
Flush the System
Periodically flushing your tankless heater helps remove any sediment or debris that could affect its performance. This can be done during regular maintenance check-ups.
Inspect and Clean Filters
Some on-demand systems have filters that need cleaning or replacing to ensure smooth operation. Econoair’s maintenance team will check these filters during service visits.
