An energy efficient pool is one that moves water slowly, stays covered when nobody is swimming and sits out of the wind and the worst sun. For an energy efficient pool Abilene TX owners should upgrade the pump first, then add a cover, then control wind and shade. A heater is the last purchase, not the first.
A porous fence, a shaded deck and a cover that gets used do more for the bill than most equipment.
The short answer
- Evaporation is the main way a pool loses heat, and the dry, windy air around Abilene speeds it up.
- A variable speed pump is the first equipment upgrade for any pool still on a single speed pump, because power use falls much faster than pump speed.
- The Department of Energy says a cover can cut pool heating costs by 50 to 70 percent, but only if your household uses it.
- Windbreaks work best when they are porous and close to the pool, and any tall structure may have to meet city pool barrier rules.
- Do not buy a heater for a pool you will not swim in during the cold months.
- Rebates and time-of-use electricity plans depend on your address, so check your own provider and PowerToChoose.org instead of assuming.
Where does an Abilene backyard pool lose the most energy?
Evaporation is the biggest loss. The Department of Energy identifies evaporation as the main way a pool loses heat. A pool in dry, windy West Texas evaporates faster than one in a humid climate. Pumping comes second, and it is the one you can fix fastest with equipment.
Abilene sits in West Central Texas, where summer air is dry and the wind rarely quits. Dry air pulls water off the surface faster than damp air does. Wind carries away the humid layer that would otherwise slow evaporation. Every gallon that leaves takes heat with it and has to be replaced with cooler fill water, which the sun or a heater must then warm. That chain is why a pool in Taylor County may need a different plan than one in Dallas or Fort Worth.
The table below shows how we would sequence upgrades. It assumes nothing about your budget, only about how the savings stack on each other.
| Upgrade | What it cuts | Worth it in Abilene when |
|---|---|---|
| Variable speed pump | Pump electricity, one of the largest regular loads on most pools | You still run a single speed pump, or yours is near the end of its life |
| Smarter pump schedule | Pump hours and peak-rate use | Always. It costs nothing |
| Pool cover | Evaporation, heat loss, makeup water and debris | You heat the pool, or you want to cut water loss |
| Windbreak | Evaporation and surface cooling | The pool sits in an open yard with nothing upwind |
| Shade structure | Summer water temperature and deck heat | The water runs warmer than you like in July and August |
| Heat pump or gas heater | Nothing. It adds a load | You want a longer swim season and have done everything above |
| LED lights | A small lighting load | You are replacing a light anyway |
Is a variable speed pump the first upgrade to make?
Yes, if your pool still has a single speed pump. A variable speed pump can run slowly for long hours, and because power falls much faster than speed, that uses far less electricity. ENERGY STAR certifies pool pumps that meet its efficiency requirements.
Pump physics explains the savings. Under the pump affinity laws, power use changes with the cube of speed. A pump at half speed draws roughly one eighth of the power while moving half the water. Real pumps give back some of that gain to friction and motor losses, so actual savings are smaller than the theory, but still large. Federal efficiency standards for new dedicated-purpose pool pumps took effect in July 2021, which is a big reason variable speed pumps are now so common.
Four steps show what your own pump costs. You need the running watts from the pump label or a plug-in meter, the hours it runs and the rate on your electric bill.
- Take the pump’s running watts and divide by 1,000 to get kilowatts.
- Multiply by the hours the pump runs each day.
- Multiply by 30 for a month, then by the rate per kilowatt-hour on your bill.
- Repeat the math for a variable speed pump at low speed, using the watts on its spec sheet.
Run that math before you spend. If your single speed pump is new and healthy, a cover may pay back faster than a swap, and the numbers will tell you which.
How many hours a day should you run the pump in Abilene?
Run it long enough to turn the water over about once a day, then adjust to how clear the water stays. In Abilene’s summer sun, expect to run longer than in spring. A variable speed pump makes the long hours cheap because it does them at low speed.
Texas lets most customers pick their electricity provider. Some plans price power differently by time of day or offer free nights. Whether those plans exist depends on the utility area your Abilene address falls in. The place to check is PowerToChoose.org, using your own address, before you build a schedule around any plan. On a flat rate, the hour makes no difference to cost. In that case, run the pump through the midday hours, when sun and swimmers are working against your sanitizer.
One schedule rule matters more than any rate plan. Do not let a timer shut the pump off during a hard freeze. The February 2021 and December 2022 freezes both showed how much damage freezing water does to idle plumbing and equipment. Our post on freeze-proofing your DFW backyard covers freeze protection in more detail.
Does a pool cover pay off in Abilene’s wind and heat?
It pays off most if you heat the pool. The Department of Energy says a cover can cut pool heating costs by 50 to 70 percent. If you never heat the pool, a cover still slows evaporation, keeps debris out and cuts makeup water. The savings show up on the water bill more than the electric bill.
- Solar (bubble) cover. The cheapest option. It floats on the surface, slows evaporation and lets some sun into the water. It needs a reel, or it will not get used.
- Automatic cover. It slides across on a track at the turn of a key. It gets used most, and use is what saves energy.
- Winter safety cover. It anchors to the deck and protects the pool, but it is not a daily cover.
Wind decides which cover works in Abilene. A loose bubble cover left out on a windy afternoon ends up in a corner or over the fence. Plan the reel or the track from day one, and buy the cover your household will actually put on. The best cover on paper saves nothing when it sits rolled up in the garage.
How do wind and shade change a pool’s energy bill?
Wind strips heat and moisture off the surface, and summer sun heats the water. Block the first and shade the second. The Save Tarrant Water program recommends fences, screens or plants close to the pool to cut wind and evaporation.
A windbreak works best when it is porous and close. A tall solid wall can push wind over the top and drop it onto the water behind it. A slatted screen, a hedge or a staggered fence slows the air down. Anything tall may also have to respect pool barrier rules and setbacks, so confirm the details with the City of Abilene before you build. We cover wind loads on posts and roofs in our Abilene patio cover post.
Shade does the opposite job in summer. At Longhorn Outdoor Living we build pergolas and patio covers. The layout question is always the same: put the structure beside the pool, not over it. A pergola on the afternoon-sun side cools the deck and seating area. A structure directly over the water tends to shed leaves and droppings into it, and the pump and filter then have to handle them.
Heat pump, gas or solar: which heater fits West Texas?
For a pool heated only in spring and fall, a heat pump is usually cheapest to run. Gas is fastest and works in cold air. Solar is nearly free but depends on sun. If you swim mostly from late spring to September in Abilene, you may not need a heater at all.
| Heater | Strength | Weak spot in Abilene |
|---|---|---|
| Heat pump | Low running cost when the air is mild | Slow, and output drops as air cools. Check the model’s minimum air temperature |
| Gas heater | Heats fast in any weather | Higher running cost, and wind pulls heat off the surface |
| Solar panels or solar cover | Almost no operating cost | Only works while the sun is up, and a cover is needed to hold the heat |
| Electric resistance | Simple equipment | Costly to run, so rarely the right pick for a backyard pool |
Abilene winter nights can drop to freezing, so a heat pump alone may not carry a pool through January. The National Weather Service office in San Angelo, which covers Abilene, publishes local climate data. Use it to check your own swim months.
The rule is simple: do not buy a heater for a pool you will not swim in during the cold months. A heater’s running cost shows up every time you flip the switch. A cover plus the sun gets many pools comfortable well into the swim season without one.
Do LED lights, filters and pool finish matter for energy?
They matter less than the pump and the cover, but they are cheap wins. LED pool lights draw far less power than the incandescent bulbs they replace. A clean filter lets the pump run at lower pressure. Finish and deck color change how hot the surface runs.
Pool finish color affects water temperature. Dark finishes absorb more sun and run warmer. That helps a pool you want to warm in spring and hurts one that already feels like a bath in August. In Abilene’s summers, a mid or light tone is usually the safer pick unless you plan to heat. Deck color follows the same logic, and our luxury coatings can help keep a deck cooler under bare feet.
Filter upkeep is the dullest saving on the list. Empty the baskets weekly and clean the cartridge or backwash on schedule. A clogged filter makes the pump push harder for the same flow.
Which upgrades come first on a small budget?
Start with the free changes, then spend in the order below. If you heat the pool, move the cover ahead of the pump.
- Fix the pump schedule and clean the baskets and filter.
- Replace a single speed pump with a variable speed pump.
- Put a cover on the water and make it easy to use.
- Add a porous windbreak on the side the wind comes from.
- Add shade beside the pool for the deck and seating.
- Buy a heater last, and only if you will swim in cold months.
Planning a new energy efficient pool in Abilene: what should you build in?
Build in a variable speed pump, plumbing sized for low flow and a spot for the cover reel or track. Lay out fences, structures and plants to block the wind on your lot. All of it usually costs less to include in the design than to retrofit later.
At Longhorn Outdoor Living we draw the equipment pad, cover storage and shade structure on the same plan as the pool and spa. Our post on building a pool in Abilene covers what to settle before anyone moves dirt. Efficiency decisions made at that stage are the ones you never have to pay for twice.

Questions we get asked about this
For most pools it is replacing a single speed pump with a variable speed pump and running it slowly for longer hours. If you heat the pool, a cover can matter just as much. The Department of Energy says a cover can cut heating costs by 50 to 70 percent. Start by working out what your pump costs per month.
Some loss is normal. Dry air and wind pull water off the surface every day, and an uncovered, unshaded pool loses more. Try a bucket test: if the pool drops much faster than a bucket of water set on the first step, look for a leak. A cover and a windbreak cut the normal loss.
A heat pump is usually cheaper to run when the air is mild. A gas heater is faster and works in cold air. Abilene winter nights can get cold enough to slow a heat pump, so check the minimum air temperature on any model’s spec sheet. If you swim mainly in summer, you may need neither.
They can, because West Texas has plenty of sun. They only heat while the sun is up and need roof or ground space. A solar cover is the simpler version. Payback depends on how many months you swim and what you pay for power or gas, so we will not quote a number.
Only if your plan makes night power cheaper, such as a free-nights or time-of-use plan. On a flat rate the hour makes no difference to cost. Daytime running keeps the water cleaner when sun and swimmers are working against your sanitizer. Check your plan’s terms at PowerToChoose.org first.
Programs change and vary by utility and retail provider. We have not verified a current program for Abilene, so ask your provider and check the offers at PowerToChoose.org for your address. Ask whether a program requires an ENERGY STAR certified model before you buy.
