Water heaters with reservoir tanks usually require a wait time to get the water hot. This usually means no impromptu showers unless you are willing to have it cold. But tankless water heaters flip that script with the convenience of instant showering with zero wait time. Here, we’ll cover both the advantages and drawbacks of these versions.
What are Tankless Water Heaters?
Tankless water heaters, otherwise known as on-demand water heaters, provide hot water without having to store it in a tank. Instead, they heat it directly as it flows through the unit. This technology ensures a reliable hot water supply whenever needed, making it a convenient choice for modern homes.
How do They Work?
When you turn on a faucet, the water travels through a pipe to the heater, where a powerful heating element, usually electricity or natural gas burners, rapidly warms it. This process eliminates the wait associated with traditional tanks and maximizes the system’s efficiency.
Pro: High Energy Efficiency
Tankless water heaters are highly energy-efficient as they are only activated when needed. This means there is no excess heating, resulting in energy savings compared to conventional models. Lower energy consumption not only reduces utility bills but also lessens your environmental impact over time.
Con: Costly Upfront
While such geysers offer long-term value for money, the initial investment is steep. Prices typically range from $1,000 to $3,000, including installation costs. Smaller electric heater models are cheaper than larger, gas-powered geyser tanks. Homeowners should weigh these expenses against future frugality to determine if this option aligns with their budget.
Pro: Environmentally Friendly
Tankless systems are environmentally friendly because they use less energy and produce relatively fewer greenhouse gas emissions. This is because they only heat water as needed, unlike traditional geysers, wherein the entire quantity of heated water may not be utilized. Thus, a tankless model positively reduces your carbon footprint.
Con: Limited Quantity Of Output
Tankless heaters have limited output capacity. If multiple outlets—like showers and dishwashers—are used simultaneously, there may not be enough warm water to satisfy the higher demand from all of these appliances. For this reason, it’s essential to assess your household’s plumbing needs before a fitting.
Pro: Saves Space
One of the most prominent benefits of tankless heaters is their compact design. These units can be mounted on walls, freeing up plenty of floor space in your home. Their small footprint makes them ideal for apartments, compact homes, or any area with limited installation space.
Con: Dependent On Electricity Supply
As mentioned earlier, tankless water geysers function on electricity or gas. For this reason, your hot water supply could be compromised during a power outage. Homeowners should consider potential backups or alternative heating methods to ensure an uninterrupted flow during emergencies.
Pro: Long-term Savings
Investing in these heaters can yield significant long-term benefits, with increased energy efficiency and lower utility bills. Many users report recovering the value of their purchase and fitting costs within five to ten years. This makes it a financially savvy choice for those playing the long game.
Con: Requires Setup Work
Installation of tankless systems can be more complicated than that of traditional geysers. The process may involve upgrading existing plumbing and electrical systems, which requires skilled laborers and, consequently, increased investment. Homeowners should be prepared for these potential renovations, which can add to overall setup time.
Pro: Longer Lifespan
Tankless geysers generally flaunt a longer lifespan of over 20 years if properly maintained. This longevity outperforms traditional tank models, which typically last only about 10 to 15 years. Such durability translates to fewer replacements and added savings in the long run.
Con: May Involve Waiting Period
Since tankless models heat water on demand, there may be a slight delay in the delivery of hot water when activated. The waiting period can range from a few seconds to a couple of minutes, depending on the distance from the device to the faucet.
Pro: Easy To Maintain
Maintaining a tankless geyser is straightforward. Routine descaling and filter cleaning are the primary steps involved in maintenance procedures. These simple steps can help extend the unit’s lifespan, ensure it operates efficiently, and keep your warm water flow lasting longer and uninterrupted.
Con: Inconsistent Temperatures
Fluctuating water temperatures can sometimes occur while using a tankless heater, especially when multiple outlets are open. This inconsistency can be frustrating, particularly during simultaneous showers or laundry cycles. Understanding your unit’s capacity and properly sizing it for your needs is essential to mitigate this issue.
Is a Tankless Water Heater Right for Your Home?
Whether or not to buy a tankless water heater depends on your lifestyle and plumbing needs. Factor in aspects such as household size, space availability, water requirements, and budget. Analyze the pros and cons carefully to determine if this modern solution fits your home.
