Energy-Efficient Well Pumps for Colorado Springs Homes: Right-Sizing, Constant Pressure & VFD Options

When homeowners ask us about the most energy-efficient well pump, the answer usually isn’t one specific pump or system. Efficiency starts with equipment properly matched to your well, your home, and how much water you actually use.

For some Colorado Springs homes, a properly sized standard well pump is the right choice. Others may benefit from a constant pressure system with a variable frequency drive (VFD) that adjusts pump speed as water demand changes.

At Barnhart Pump Co., we look at the entire water system before recommending an upgrade. Our goal isn’t to install more pumps or more technology than you need. It’s to recommend a system that performs reliably and efficiently for your specific property.

What Makes a Well Pump Energy Efficient?

A well pump doesn’t operate efficiently on its own. The pump, motor, pressure tank, controls, plumbing, well conditions, and household water demand all work together.

When we size a well pump, we consider factors such as:

What We Evaluate	Why It Matters
Well depth and pumping water level	Determines how far the pump has to move water.
Well production rate	Helps us choose a pump that won’t outpace the well’s ability to recover.
Household water demand	Determines how much water the system needs to deliver during peak use.
Pressure needs	Affects the pump, pressure tank, and controls needed to deliver comfortable pressure.
Elevation and plumbing	Distance, elevation changes, and friction all affect how hard the pump has to work.
Pump controls	Determines whether the pump runs at a fixed speed or can adjust to changing demand.

The most efficient pump is generally the one that is properly sized for the work it actually needs to do.

Is a Bigger Well Pump More Efficient?

Bigger is not automatically better when it comes to well pumps.

An oversized pump may deliver more water than your home needs and can cycle on and off too frequently in a conventional system. That short cycling wastes energy and can shorten the life of the pump motor.

An undersized pump creates a different problem. It may struggle to keep up when several fixtures or appliances are using water at the same time.

That is why we don’t choose a pump based on horsepower alone. We calculate your household’s water demand, well depth, pumping water level, well production, elevation, pressure requirements, and other system conditions before recommending a size.

What Is a Constant Pressure Well Pump?

A constant pressure well pump system is designed to provide steadier water pressure as demand changes throughout your home, while a traditional well system typically uses a fixed-speed pump. When pressure drops to a certain point, the pump turns on and runs at full speed until the pressure tank reaches its upper setting.

Constant pressure systems utilize pressure sensor and a variable frequency drive, or VFD, to change the speed of the pump motor based on how much water you are using.

If you turn on one faucet, the system may only need part of the pump’s capacity. If two showers, the washing machine, and irrigation are running at the same time, the pump can increase its output to meet the additional demand.

The result is more consistent pressure without requiring the pump to operate the same way every time someone turns on the water.

Can a VFD Make a Well Pump More Energy Efficient?

The short answer: It can in the right system.

Because a VFD well pump can change speed as water demand changes, the motor does not necessarily have to run at full output every time water is used. Variable-speed operation can reduce energy use when the system regularly experiences changing flow demands. 

But a VFD is not automatically the most efficient choice for every well.

If your water demand is relatively predictable and your current system is properly sized, a standard well pump may already be a practical and efficient option.

That is why we look at the well and the way your household uses water before recommending a variable-speed system.

Are Constant Pressure Systems More Efficient?

Constant pressure systems can improve efficiency in the right application, but energy savings aren’t their only advantage.

Many homeowners are more interested in what they notice every day: steadier pressure.

A constant pressure system may be a good fit if you:

• Notice pressure dropping when several fixtures are used at once
• Have a larger household with frequent simultaneous water use
• Run irrigation while using water inside the home
• Want more consistent shower pressure
• Are replacing an existing pump and want to explore variable-speed options
• Have limited space for a traditional large pressure tank

VFD systems also allow the pump to start and stop more gradually, rather than immediately going from off to full speed.

The biggest benefit is having a system that can respond more closely to changing water demand. Whether that translates into meaningful energy savings depends on the well, pump, and way the property uses water.

When Is a Standard Well Pump Still the Right Choice?

Not every home needs a VFD or constant pressure system.

A properly sized conventional well pump can be an excellent choice when the well has adequate production, household demand is relatively consistent, and the existing pressure setup meets the homeowner’s needs.

There is no advantage to adding complexity simply for the sake of having a more advanced system.

We recommend the setup that makes sense for your unique property. Sometimes that is a variable-speed constant pressure system. Other times, a properly sized standard submersible pump is exactly what the home needs.

How Low Water Pressure Can Affect Pump Efficiency

If your water pressure has dropped, installing a bigger pump is not always the answer.

Low water pressure can come from several places in the system, including:

• An aging or failing pump
• Pressure tank problems
• A failing pressure switch or control
• Plumbing leaks or restrictions
• Increased household water demand
• Low well production

Our first step is to figure out what has changed.

If your pump is properly sized but wearing out, replacing it with the appropriate new pump may solve the problem. If you’ve added bathrooms, irrigation, or other water demands since the original system was installed, your needs may have changed enough to consider a different pump or constant pressure system.

And if the well itself is not producing enough water, installing a larger pump won’t create more water. In that situation, we may recommend pump protection, storage, or another low-producing well solution instead.

	Standard Well Pump System	Constant Pressure/VFD System
Pump operation	Runs at a fixed speed	Adjusts speed as demand changes
Water pressure	Moves between pressure-switch settings	Designed to maintain steadier pressure
Pressure tank	Typically larger	Typically smaller
Good fit for	Predictable household demand and comfortable existing pressure	Changing demand or homes where consistent pressure is a priority
Efficiency	Can be very efficient when properly sized	May improve efficiency when variable-speed operation fits the application

 

The best system is the one that matches your well, your household demand, and the way you use water.

Choosing an Energy-Efficient Well Pump in Colorado Springs

Colorado Springs-area well systems can vary significantly from one property to another. A home in Black Forest may have very different well depth, water level, and production than a property in Peyton or Fountain.

Those differences matter when selecting a pump, as much as working with a well company that understands your unique situation, needs, and landscape. 

Barnhart Pump Co. has worked with Colorado well systems since 1983, and our team brings more than 100 years of combined experience to pump sizing, installation, troubleshooting, and repair. We work with standard submersible pumps, constant pressure systems, VFD pumps, low-producing wells, and other residential water system needs throughout the Pikes Peak region. 

That experience allows us to look beyond horsepower or an efficiency claim on a specification sheet. We want to know how the system will actually perform in your well and your home.

Let Barnhart Help You Choose the Right System

Frequently Asked Questions

What water well pumps are energy efficient in Colorado Springs?

There isn’t one pump that is the most efficient for every Colorado Springs home. A properly sized standard pump can be very efficient, while some homes may benefit from a variable-speed or constant pressure system. The right choice depends on well depth and production, household demand, pressure requirements, and how the property uses water.

Are constant pressure systems more efficient?

They can be. A constant pressure system uses a VFD to adjust pump speed as water demand changes, which can improve operating efficiency in the right application. For many homeowners, the biggest benefit is more consistent pressure when several fixtures are being used at the same time.

Can a VFD help my well pump use energy more efficiently?

Yes, particularly when water demand varies throughout the day. A VFD allows the pump to slow down when full output isn’t necessary and increase speed as demand rises. Whether it makes sense for your home depends on the pump, well, pressure requirements, and water-use pattern.

Is a bigger well pump better or more efficient?

Not necessarily. An oversized pump can cycle too frequently, while an undersized pump may struggle to meet demand. The most reliable and efficient approach is to size the pump for the actual requirements of the well and home.

Will a VFD fix low water pressure?

It can help when changing or high household demand is contributing to pressure fluctuations, but it will not solve every low-pressure problem. We recommend identifying the cause first so we can determine whether the right solution is a repair, pump replacement, different sizing, or a constant pressure system.
