How to get hot water fast by installing a dedicated electric water heater

Proper installation of a water heater is crucial for its long-term and uninterrupted operation, as well as efficient hot water delivery. It's important to install the water heater with a piping system that is as short as possible and strategically located near the fixtures where hot water is needed, such as bathrooms, kitchens, laundry areas, and garages.

If you have a sink that is far away from the water heater, resulting in slow hot water delivery, consider installing a point-of-use water heater (POU), such as an Eemax, Tempra or Tronic tankless or Ariston as the small tank-type appliance.

When there is a considerable distance between the water heater and a fixture, it takes time for hot water to reach the desired location because the cold water stored in the pipes needs to be pushed out first. By minimizing the distance between the heater and the fixture, you can expedite the removal of cold water from the pipes, resulting in faster hot water delivery, regardless of whether you have a tankless or tank-type water heater. Additionally, it is recommended to insulate all water lines, especially those running through areas with lower temperatures, to further optimize heat retention.

When purchasing a water heater, it is essential not to solely rely on marketing terms like "instantaneous." While true instantaneous hot water may not be achievable in all cases, there are effective solutions available, such as recirculation systems and boosters, that can provide you with near-instant hot water when needed. These options ensure that you have quick access to hot water without any frustrating delays.

By considering factors like installation location, distance, insulation, and the right supplementary systems, you can enhance the efficiency and performance of your water heater, guaranteeing a steady supply of hot water whenever you need it.

How to get hot water faster by installing a tankless water heater with the recirculation

If you're in the market for a tankless water heater that offers the convenience of a built-in recirculation system, look no further than the exceptional Navien NPE-A and Rinnai RUR series. These innovative models go beyond standard tankless water heaters by incorporating advanced recirculation technology, ensuring hot water is delivered swiftly and efficiently throughout your home.

Now, let's delve into a brief overview of both models.

Navien NPE-A series

Navien NPE-A-NV

The Navien NPE-A series offers three models designed for different home sizes: NPE-180A, NPE-210A, and NPE-240A. These models have a gas input of up to 199,900 BTU and a water flow of up to 11.2 GPM (with a temperature rise of 35°F). The largest model, NPE-240A, is suitable for large homes with up to 4 bathrooms. However, if you require less power or water flow, you can opt for one of the two smaller models.

All models come equipped with an internal circulation pump, and it is also possible to add an external pump to the water heating system for recirculation applications. It's important to ensure that the external pump is appropriately sized to provide the desired water flow. The circulation pump is responsible for speeding up the delivery of hot water.

This ultra-high efficient series of tankless water heaters achieves a remarkable energy factor of 0.95, resulting in significant savings for users. The low gas emission burner and environment-friendly operation contribute to its efficiency.

One standout feature of the Navien NPE-A models is the ComfortFlow technology, which sets them apart from other models or brands. This technology minimizes water temperature fluctuations within the system, ensuring more enjoyable showers and hot water delivered when needed. The system recognizes usage patterns, saving water and time when utilizing the recirculation mode.

Only the NPE-A models offer two pre-heating modes: internal and external recirculation mode. The mode is selected by adjusting the position of the DIP switch (which is initially set to OFF) and positioning the 2-way valve. The process of switching between the two modes is simple and straightforward.

Internal recirculation mode

Set the 2-way valve to "INT." position

Set the DIP switch to 1-ON, 2-OFF

External recirculation mode

Set the 2-way valve to "EXT." position

Set the DIP switch to 1-OFF, 2-ON

Regardless of the chosen mode, you can expect fast hot water delivery with minimal occurrence of the "cold-water-sandwich" effect, and there is no minimum water flow rate requirement.

In situations requiring additional hot water, the cascading capability of the NPE-A models allows up to 16 units to be linked into a single system.

For convenient operation, all these features can be controlled from the main command center located on the unit's front panel. The advanced electronics enable users to easily control, monitor, and troubleshoot the system using the provided error codes from the diagnostics system.

Maintenance is also crucial. For instance, the inlet water filter located inside the cold-water inlet should be periodically cleaned to ensure proper water flow. Any obstructions within the filter can result in reduced flow and slow water delivery.

Rinnai RUR

Rinnai RUR199 tankless water heater

Rinnai tankless RUR water heaters like the aforementioned Navien units, are on-demand systems that provide an endless supply of hot water. Thanks to advanced electronics, these units offer consistent temperatures and greatly reduce the occurrence of the "cold-water-sandwich" effect.
