Understanding Tankless Water Heaters

Tankless water heaters, also known as on-demand hot water systems, have been gaining popularity due to their functionality and eco-friendly aspects. Unlike traditional tank-type water heaters that heat and store a large volume of water, these units operate by heating the cold water only when there’s demand for it.


This is achieved through either an electric element or gas burner which heats the incoming cold water before it reaches your faucet. This ensures an endless supply of hot water without waiting for a storage tank to fill up.

One major advantage of tankless technology over its conventional counterpart is energy efficiency. Since they don’t constantly maintain a full reservoir of heated water like in a typical storage tanks system, standby heat losses are significantly reduced.


Eco-Friendly Aspects of Tankless Water Heaters


The principle behind how tankless systems work directly contributes towards reducing carbon footprint. It helps conserve more natural resources because less energy is wasted keeping stored hot in case you need it; instead, you get instant access whenever required.


In terms of performance measures such as BTU ratings – commonly used to gauge heating power – tankless models show a considerable range: from less than 60,000 to over 220,000. In comparison with electric units’ wattage varying from 2400 W up till around 36000 W.

Apart from being environmentally friendly and providing unlimited warm showers (yes.), they can be more cost-effective too. These benefits make them not just another alternative but potentially a better choice compared against older style heater setups out there today where chances are high some form degradation has already occurred due to hard use combined effects wear tear alongside potential mineral buildup inside from hard water over time.


However, the tankless water heater cost might be higher initially than a traditional model. Despite their higher initial price tag, tankless water heaters can be more cost-effective in the long run as they consume less energy and have a longer life expectancy – potentially up to 20 years or even more with proper upkeep.


With these modern heaters, you get more than just efficiency – their compact size lets you install them easily in any part of your home. You can even opt for an outdoor tankless water heater if that’s what suits your needs best. And the cherry on top, many models come packed with smart tech features, making them a breeze to operate. The Right Tankless Water Heater For Each Home

Understanding the type of tankless water heater that is right for your hone might seem daunting, but this guide will help outline the variables.


Choosing The Right Tankless Water Heater


The first factor is all about your home and lifestyle. There are a lot of factors at play with this one. Square footage of your house, the number of people in the household, the number of bathrooms in the house, and various potential lifestyle characteristics. In this case, consulting with an expert who specializes in tankless water heaters can ensure you get the right product for your unique needs.


With regards to cost-efficiency, higher BTU ratings mean that they can heat up water faster at a lower cost. One key way in which this is felt is flow rate and temperature rise capabilities. For example, a unit offering 1.32 gallons/min at 35°F rise in temperature would suffice for small households with fewer hot-water needs compared to another offering up to 11.2 gallons/min under the same conditions.


So, What is BTU Rating?


The BTU (British Thermal Unit) rating of your heater is a key player. This rating gauges how much heat it takes to bump up the temperature of one pound of water by just one degree Fahrenheit. So, if you’re eyeing heaters with higher BTUs, know that they can pack more heat.


Noritz Tankless Water Heaters


When it comes to tankless water heaters, Noritz stands out for their wide array of models and series. They offer units that cater to various needs, making them a popular choice among homeowners.

Earlier this year The United States Environmental Protection Agency (EPA) put forth new regulations, marking a significant step in addressing the potential harm posed by "forever chemicals" known as per- and polyfluoroalkyl substances (PFAS) in drinking water. While certain states have enacted laws to regulate PFAS in drinking water, there has been a notable absence of federal mandates, resulting in a lack of uniformity in testing and filtration procedures across public water systems. However, the EPA's current proposal represents a historic shift in addressing this critical issue. Understanding PFAS and the Rationale for Regulation: PFAS, characterized by their persistence in the environment and the human body, are synthetic compounds renowned for their resistance to water, oil, and grease. Their widespread use in everyday consumer products, ranging from waterproof jackets to nonstick cookware, has raised concerns about their potential health and environmental implications. Regulation of PFAS is imperative for several reasons: 1. Human Health Impacts: A growing body of research has linked PFAS exposure to a range of health issues, including liver damage, immune system dysfunction, hormone disruption, developmental delays in children, and an elevated risk of certain cancers. These health concerns underscore the need for rigorous regulation. 2. Environmental Concerns: PFAS have infiltrated water supplies, soil, and even the bloodstream of a substantial portion of the U.S. population. Groundwater near industrial sites, military bases, and areas where firefighting foams were used is particularly susceptible to PFAS contamination. This widespread presence has heightened concerns about the safety of drinking water. Impact of the Proposed Standards on Tap Water Quality: While homes across southern California have increasingly benefited from whole house water filtration systems to purify their water, the introduction of these new PFAS standards promises improvements in the quality of tap water for consumers, for everyone. Key implications include: 1. Cleaner and Safer Tap Water: The proposed regulations would impose more stringent guidelines, obliging water suppliers to implement measures to reduce PFAS contaminants. This will result in cleaner and healthier tap water for consumers. 2. Enhanced Quality Control Measures: The standards require water suppliers to adopt robust testing and monitoring procedures for PFAS levels in the water supply. This proactive approach will expedite the identification and mitigation of potential issues, ensuring consumers have confidence in the safety of their tap water. 3. Protection for Vulnerable Populations: Individuals particularly vulnerable to PFAS exposure, such as children, pregnant women, and those with weakened immune systems, stand to benefit from these standards. Lower PFAS levels in tap water reduce health risks and contribute to the well-being of these groups. Protecting Your Water from PFAS: While the proposed regulations are a positive step in the right direction, we are still a long way from seeing any notable impact at the local level. In the meantime, we encourage individuals to take proactive measures to safeguard their drinking water: 1. Water Testing: Conducting laboratory tests to ascertain PFAS contamination in your water supply is a prudent step. Utilizing a water test kit and sending a water sample for analysis ensures accurate results. 2. Installation of Water Filtration Systems: If PFAS is detected, consider installing high-quality water filtration systems. Two effective options are reverse osmosis and activated carbon filtration, both capable of removing PFAS from drinking water. Through a complex 6-stage process the Agape Waters Water Treatment System, (in conjunction with our 5-micron post-carbon filter,) eliminates chlorine, chloramines, lead, heavy metals, chromium-6, pesticides, bacteria, and VOCs (Volatile Organic Compounds,) greatly reducing hard water calcium and magnesium scale from forming and lowering the surface tension in the water. This 6-stage process includes a double high-strength magnetic pass, a 3-chamber catalytic surface treatment, and KDF (Kinetic Degradation Fluxion) media flow through. With the water being in an up-flow stream, no regeneration backwash maintenance is required and the high-strength magnets act as the power source which means that no electrical power source is needed. This Agape Waters Custom Water Treatment System is unique to the industry and patent pending with a service life of 12+ years. Conclusion: The EPA's proposed regulations offer the potential for significant improvements in tap water quality in the years ahead. Until these regulations are fully implemented, it is advisable to test your water for PFAS and explore the benefits of reliable water filtration systems, such as reverse osmosis or whole-house activated carbon filters, should PFAS contamination be detected. These proactive measures aim to ensure the safety and well-being of individuals and communities by mitigating the risks associated with PFAS exposure.
