Now that we’ve established the frustration of waiting for hot water and introduced Navien as a potential solution, let’s delve into the mechanics of how these recirculation systems actually work.
Understanding the fundamental principles will empower you to make informed decisions about whether a recirculation system is right for your home and lifestyle.
What is a Recirculation System?
At its core, a hot water recirculation system is designed to keep hot water readily available at your faucets and showers, eliminating the wait and the associated water waste.
Instead of waiting for water to travel all the way from your water heater to the fixture, a recirculation system ensures hot water is always present in the pipes.
This is achieved through a closed-loop system that continuously circulates water.
The Role of the Circulator Pump
The heart of any recirculation system is the circulator pump.
This pump is responsible for moving the hot water from the water heater through the plumbing lines and back again.
It ensures a continuous flow, so the water remains hot and ready for use. Without a pump, the water would simply sit in the pipes and cool down, defeating the purpose of the system.
Dedicated Return Line vs. Cold Water Line Recirculation
There are two primary types of recirculation systems: those with a dedicated return line and those that utilize the cold water line.
A dedicated return line provides a separate pipe specifically for the return of cooled water back to the water heater. This is the more efficient method, as it doesn’t affect the temperature of the cold water supply.
Cold water line recirculation uses the existing cold water line as the return path.
While this can be a more cost-effective installation in some cases, it can lead to a temporary warming of the cold water supply when the recirculation system is active. This is an important consideration for homeowners.
Benefits of a Recirculation System
The advantages of installing a hot water recirculation system extend beyond mere convenience. They offer tangible benefits in terms of water conservation, cost savings, and overall energy efficiency.
Instant On-Demand Hot Water
This is the most obvious and immediate benefit.
No more waiting, no more wasted water. Just instant hot water whenever you need it.
Eliminating the "Cold Water Sandwich"
The "cold water sandwich" occurs when you turn off the hot water for a short period, and then turn it back on, only to be greeted by a burst of cold water before the hot water arrives.
A recirculation system eliminates this frustrating phenomenon by maintaining a consistent temperature throughout the plumbing system.
Water Conservation
Waiting for hot water to arrive at your faucet or shower wastes a significant amount of water.
A recirculation system minimizes this waste by ensuring hot water is always readily available, reducing the amount of water that goes down the drain.
Over time, this adds up to a substantial saving.
Cost Savings
Water conservation directly translates to cost savings on your water bill.
Furthermore, by reducing the amount of energy required to heat up cold water sitting in the pipes, a recirculation system can also lower your energy consumption and associated costs.
Energy Efficiency
Recirculation systems, when properly installed and used, improve overall energy efficiency.
By keeping hot water circulating, the system reduces the amount of energy required to heat water from a cold start, contributing to a smaller carbon footprint and lower utility bills.
Who Benefits Most?
While anyone can benefit from a hot water recirculation system, certain homeowners will experience the most significant advantages.
Large families with multiple bathrooms and frequent hot water usage will see substantial water and energy savings.
Homes with long plumbing runs from the water heater to the fixtures will also benefit greatly from the reduced wait times and water waste.
Finally, individuals who simply value convenience and comfort will appreciate the luxury of instant hot water on demand.
