Infographic guide for selecting tankless electric water heater showing flow rates and zones.

Understanding Tankless Electric Water Heaters

Tankless electric water heaters are revolutionizing home hot water access, providing an energy-efficient and space-saving alternative to conventional water heaters. Unlike traditional units, they heat water on demand, drastically reducing energy costs due to their compact size—some models are up to 98% smaller than conventional storage heaters. For homeowners looking to upgrade, choosing the right model is crucial, as it must align with their specific needs and household dynamics.

Assessing Your Hot Water Demand

Before making a selection, the first step in this journey is estimating your household's hot water demand. This demand is typically measured in gallons per minute (GPM). Homeowners should tally the flow rates of all fixtures that will be used simultaneously. For instance, if a shower runs concurrently with two sinks, the required GPM may total five or more, indicating the need for a larger unit. Popular models from brands like Rheem® and EcoSmart cater to diverse requirements—from compact options ideal for single fixtures to robust choices for multi-bathroom homes.

Regional Considerations are Key

Regional climate plays a crucial role in tankless heater selection. In colder regions, groundwater temperatures impact performance—affecting the unit's heating capacity. For homes in the South where groundwater is warmer, achieving a desired output is simpler compared to homes in Northern states where groundwater temperatures can be significantly lower. Homeowners must choose models that are sufficiently powerful to meet these demands, especially in colder climates.

Electrical Capacity Matters

Finally, evaluating your home's electrical capacity is vital. Tankless electric water heaters require adequate power to function efficiently, and older homes may not always support the necessary load. Homeowners should consult with an electrician if needed to ensure the electrical system can handle the demand of a new heater.

In conclusion, when selecting a tankless electric water heater, thoughtful consideration of household hot water demand, regional climate, and electrical capacity will lead to a well-informed purchase decision. For those ready to make a change, examining these areas ensures optimal performance and long-term satisfaction.

Shield Your Home: 4 Ways to Protect Your HVAC From Natural Disasters

Update Protect Your Home: Safeguarding Your HVAC System from Natural Disasters As natural disasters become increasingly frequent and intense, homeowners must rethink how they protect critical systems in their homes, particularly the HVAC (Heating, Ventilation, and Air Conditioning) system. While many focus on securing windows and roofs, it’s equally important not to neglect the HVAC system, which is essential for indoor comfort year-round. Why Shielding Your HVAC Matters HVAC systems are often vulnerable to damage caused by extreme weather phenomena such as hurricanes, floods, and wildfires. Whether it's electrical surges during a storm or water damage from flooding, the costs associated with repairing or replacing an HVAC system can be significant. Preventive measures can minimize risk and extend the life of your equipment, securing your home’s comfort during critical times. Four Essential Steps to Protect Your HVAC System Power Down Before the Storm: Prior to any severe weather, turning off your HVAC system at the circuit breaker not only mitigates the risk of electrical damage but also protects it from potential flooding. Installing surge suppressors can provide an added layer of protection by absorbing surges that might otherwise cause severe damage. Secure Outdoor Units: High winds can wreak havoc on outdoor HVAC units, causing physical displacement or damage from flying debris. Bolting your unit securely and removing potential airborne hazards, such as patio furniture, are simple yet effective measures homeowners can take. Guard Against Flooding: For those living in flood-prone areas, elevating outdoor HVAC units is critical. Consider positioning your equipment on concrete or composite platforms to safeguard against rising waters. Always have your system inspected by a professional before restarting post-flood to avoid electrical hazards and mold growth. Regular Maintenance is Key: Routine inspections from qualified technicians ensure your HVAC system is ready for unpredictable weather. Scheduling maintenance before and after severe storms can help detect hidden issues early, keeping your system functioning efficiently. Conclusion: Preparedness is Your Best Defense Preparation is crucial in the face of natural disasters. By taking actionable steps to protect your HVAC system, homeowners not only reduce the risk of expensive repairs but also enhance their overall comfort and safety.
