Introduction to Energy Savings in Modern Homes

In today’s world, energy efficiency is more important than ever before. With rising energy costs and increasing awareness of our environmental impact, homeowners are looking for ways to reduce energy usage and save money. One often overlooked area where significant energy savings can be achieved is water pumping.

Traditional water pumps are extremely energy-intensive, accounting for nearly 10% of a home’s energy costs on average. By switching to a more efficient pumping system, homeowners can unlock substantial energy and cost savings. This is where submersible pumps come into play.

Submersible pumps provide a high-efficiency, eco-friendly pumping solution that is revolutionizing modern homes. Compared to traditional pumps, submersible models offer significant advantages:

• Far greater energy efficiency and savings
• Lower operating costs over the lifetime
• Reduced environmental impact
• Reliable, low-maintenance operation
• Longer service life
• Easy installation
• Improved aesthetics

In this comprehensive guide, we will take an in-depth look at how submersible pumps work, their key benefits, and how they can help you unlock energy savings in your modern home.

What are Submersible Pumps?

Submersible pumps are a type of electric water pump designed to operate while fully submerged in the water being pumped. The key components of the pump including the electric motor, impeller, and pump housing are hermetically sealed inside a watertight enclosure that allows the entire unit to be safely immersed underwater.

Unlike traditional well pumps that sit above ground, submersible models are designed to be installed directly into a well or tank below the water line. This unique construction provides greater efficiency and maintains cooler operating temperatures by remaining submerged.

Submersible pumps have been used in industrial and commercial settings for decades, but recent advances in materials and motor efficiency have made them ideal for residential applications. Their energy-saving capabilities make them one of the best choices for modern eco-friendly homes.

History of Submersible Pumps

• The origins of the submersible pump date back to the mid-1800s when simple piston pumps attached to long rods were used to manually pump water from underwater wells.
• In the 1860s, French physicist Ernest Sulzer invented one of the first submersible pumps driven by a semi-enclosed electric motor.
• In 1929, Pleuger Pumps pioneered the first fully submersible pump enclosed in a watertight casing.
• The technology was further advanced in the 1930s by Germany’s KSB Group and United States companies Reda Pump and Pleyuger.
• The development of sealed shaft coupling technology in the 1950s eliminated oil leaks, allowing reliable water-lubricated motors.
• Modern submersible pumps emerged in the 1960s with affordable stainless steel parts and better electric motors.
• Today, submersible pumps are a mature technology used worldwide in countless residential, agricultural, industrial, and municipal applications.

The evolution of submersible pump engineering over the last century has led to today’s extremely reliable and energy-efficient models.

Types of Submersible Pumps

There are two main types of submersible pumps used in residential settings:

Submersible Well Pumps

Designed for use in drilled wells to supply potable water for homes.

• Set down inside the well casing below the water line
• Lift water from depths up to 300 feet
• Discharge through piping into pressure tank and plumbing system
• Handle clean water only

Submersible Effluent Pumps

Used to pump away wastewater or sewage from a home.

• Installed in septic tanks, lift stations, or piping
• Discharge sewage away from home to treatment system
• Able to reliably pump abrasive effluent laden with solids
• Require robust hardened impellers and volute casings

In addition to these two main residential types, there are various configurations of submersible pumps for specialized applications like fountains, ponds, swimming pools, and more.

The Science Behind Submersible Pumps

Submersible pumps operate based on some fundamental laws of physics and fluid mechanics:

• Pascal’s Law – Pressure exerted on a static fluid is transmitted undiminished to all points in the fluid. This allows pressure to be created by the pump.
• Bernoulli’s Principle – As fluid speed increases in a constricted section of pipe, pressure decreases. The impeller generates velocity to lower pressure.
• Impeller Rotation – Spinning the impeller blades forces fluid to move using centrifugal force. Faster speeds increase pumping capacity.
• Volute Casing – The pump volute captures the kinetic energy from the impeller and converts velocity to pressure. Efficient volute design is key to performance.
• Priming – Pumps require initial priming to fill the intake with water. Submersibles use built-in priming aids and volute designs to self-prime.

Understanding these scientific principles helps explain how submersibles are engineered to lift water efficiently using an enclosed electric motor.

Key Components of a Submersible Pump

While submersible pump configurations vary across models, they share several key components:

• Electric Motor – Powers the impeller. Designed for continuous submerged operation with water-tight sealing.
• Impeller – Rotating component with blades that imparts velocity to move the pumped fluid.
• Pump Volute – Casing that captures kinetic energy and converts it to pressure. An efficient spiral design minimizes turbulence.
• Bearings – Allow smooth rotation of the shaft connecting the motor to the impeller. Robust bearings handle pumping forces.
• Seal Section – Prevents water from entering the motor by sealing around the rotating shaft. Allows pressure equalization.
• Intake Screen – Prevents solid debris from entering the pump and causing damage. Usually stainless steel mesh.
• Discharge Pipe – Transports pumped water to exit the well. Typically PVC or stainless steel.

When these components work together in an optimized design, high-efficiency pumping can be achieved even underwater.

How Submersible Pumps Work

The step-by-step operation of a submersible pump is fairly straightforward:

1. The pump is installed into the well below the water level
2. Electric cable brings power to the sealed motor
3. A motor spins the impeller via a rotating shaft
4. Impeller motion creates flow by centrifugal force
5. Volute casing converts kinetic energy into pressure
6. Pressurized flow exits pump through a discharge pipe
7. Water flows out of the well to the storage tank/plumbing
8. The pressure sensor turns the pump motor on/off automatically

This reliable process repeats constantly, varying motor speed as needed to match demand. The pump and all components remain safely underwater, maintaining cool running temperatures for optimal performance.

Benefits of Using Submersible Pumps

Compared to conventional above-ground well pumps, submersibles offer a number of compelling benefits:

Energy Efficient

• Submerged operation keeps components cool for less energy loss
• No long suction pipe means less friction loss
• Advanced motor and impeller engineering

These advantages make submersible pumps the top choice for energy efficiency, reliability and ease of use compared to older-style well pumps.

Energy Efficiency: A Closer Look

One of the biggest advantages provided by submersible pumps is dramatically improved energy efficiency compared to conventional above-ground pumps.

Several factors contribute to the superior efficiency:

• Cooler operation – Submerged pumps dissipate heat and run 20-30°F cooler than air-cooled models. Cooler motors convert more electric energy into pumping work rather than losing energy as heat.
• Shorter suction piping – Submersibles eliminate long vertical suction pipes, reducing friction losses. Shorter inlet piping improves efficiency by 3-5%.
• Optimized components – Superior motor, impeller, and volute casing designs increase pumping efficiency compared to older pumps.
• Larger passages – Unobstructed waterways without valves reduce turbulence and friction losses.
• Variable speed – Matching motor speed to demand optimizes efficiency across pumping conditions.

As a result of these design advantages, submersible pumps achieve pumping efficiencies of over 90%, compared to 70-80% for typical above-ground pumps. This directly translates into substantial energy savings over time.

Comparing Traditional Pumps to Submersible Pumps

To understand the real-world efficiency gains, it is useful to compare submersibles to conventional above-ground centrifugal and jet pumps commonly used in well systems:

Pump Type	Typical Efficiency	Motor Location	Suction Lift	Service Location	Typical Life
Submersible	90% +	Submerged	None	In-place	15-20 years
Centrifugal	70-80%	Above ground	Up to 25 ft	Pull from well	10-15 years
Jet (injector)	65-75%	Above ground	None	Pull from well	5-8 years

The high efficiency and submerged design of submersibles provide significant performance and maintenance advantages. In many homes, switching to a submersible pump can reduce pumping energy requirements by 25% or more.

Case Study: A Homeowner’s Experience

Mark installed a new submersible pump to replace the aging and unreliable jet pump in his country home built in the 1980s.

The existing jet pump was marginally able to keep up with water demands in the home, even after servicing. Mark’s power bills were also higher than expected.

After installing the submersible pump system professionally, Mark immediately noticed stronger and steadier home water pressure. Faucets no longer slowed to a trickle intermittently. Shower temperatures remained constant, without the wild swings his old pump caused.

Most importantly, Mark’s electric bill dropped by $55 per month, providing significant savings. Maintenance has also been worry-free, with no failures in the 3 years since installing the submersible.

Switching to a submersible pump improved Mark’s home water supply, reduced power costs, and provided peace of mind with a modern and robust system requiring minimal upkeep. This real-world example highlights the benefits submersible pumps can provide homeowners.
