Types of Pentair Pool Heaters

The first decision to make when choosing a Pentair pool heater is identifying the right energy source to power it. Pentair offers pool heating solutions running on electricity, natural gas, or geothermal heat extracted from the air. Each approach has its advantages.

Heat Pump Pool Heaters

For a green and energy-efficient option, consider a Pentair pool heat pump. These units extract latent heat from the surrounding air and transfer it to the pool water. The heat extraction process makes them very economical to operate. Just take care when sizing – heat pumps lose heating capacity in colder weather.

The UltraTemp® series from Pentair stands as one of the most popular heat pump pool heater options. UltraTemp heat pumps come in a variety of sizes from 90,000 BTU to 140,000 BTU units. This allows heating pools ranging from 15,000 to 40,000 gallons. These low-profile units can be mounted flush on the ground or wall-mounted.

Gas Pool Heaters

Pentair also offers several lines of conventional gas pool heaters for reliable heating performance. Units range from 150,000 BTU capacity up to 400,000 BTU commercial-grade models.

The MasterTemp® line uses a proprietary pre-mixed gas combustion method to maximize heating efficiency. Plus, built-in diagnostics make it easy to troubleshoot issues when they arise. If you seek a basic and affordable gas heater, the Lite2TM series may suffice to warm your pool.

Electric Pool Heaters

Finally, consider electric heaters like the Sta-Rite® Max-E-Therm® for small to mid-size pools. Connecting to a 240-volt power supply, an electric Pentair heater can reach temperatures between 65°F to 104°F. Sizing flexibility ranges from 150,000 to 250,000 BTU units. While electric heaters cost more to operate, they avoid combustion byproducts.

Proper Pentair Heater Installation

Installing a pool heater requires careful planning and preparation for smooth and safe operation. When adding any Pentair heating unit, be sure to follow a few key guidelines.

Review Manuals and Specs

While Pentair heaters come preassembled from the factory, proper installation is critical. Always thoroughly read the entire product manual and follow all instructions for locating, mounting, and connecting your heater. Pay close attention to clearance requirements, ventilation guidelines, gas or electric connections, and automated control settings.

You’ll also want to confirm that your prospective Pentair model meets the BTU specifications recommended for your pool size. An undersized heater can struggle to reach desired temperatures.

Leverage Pentair’s Customer Support

Even after studying all manuals, questions may arise during installation or operation. Thankfully, Pentair offers stellar technical support via their customer service team. Their USA-based call center has won awards for expert assistance.

Before calling, have your Pentair heater model and serial number handy for easy reference. The team can walk through diagrams, troubleshooting, and parts replacement to get your heater running at maximum performance.

Consider Professional Installation Help

Finally, don’t hesitate to have a pool pro installer evaluate your setup and oversee the heater introduction. An experienced technician already knows all the ins and outs of proper Pentair product connections, compliance with codes, and identifying potential issues early. Paying for professional installation can give priceless peace of mind and help qualify for full Pentair warranty coverage.

 

Sizing Your Pentair Pool Heater

Choosing the appropriately sized Pentair pool heater ensures your unit can adequately handle the heat load requirements of your pool. A properly sized heater should maintain your desired water temperature while maximizing efficiency.

Calculate Needed BTUs

The necessary heating capacity for your pool is measured in BTUs or British Thermal Units. Factors like a pool’s surface area, desired temp increase, and local climate all help determine required BTUs.

As a general guideline, plan on 100 BTUs to heat one square foot of pool surface by one degree Fahrenheit.

So a 500 square-foot pool wanting a 20°F temp increase would need about 100 x 500 x 20 = 1,000,000 BTUs (or 1MBTU). Add another 10-30% extra BTU capacity as a buffer.

Match Heater Size to Pool Gallons

Most pool pros recommend selecting a Pentair model rated for about 100 BTUs for every gallon of water volume.

For example, a 15,000-gallon above-ground pool would need around 140,000 BTU heating capacity. That matches up well with Pentair’s UltraTemp 140 heat pump pool heater.

Consider a High-Capacity Model

For especially large inground pools, install an upper-tier Pentair heater like a 400,000 BTU MasterTemp gas heater. This scales up to handle commercial-size public pools.

An oversized Pentair unit only runs partially as needed, avoiding overworking at full throttle all the time to heat every last gallon. This improves longevity while delivering toasty pool temps!

 

Operating and Maintaining Your Pentair Heater

To achieve reliable and energy-efficient performance for years to come, proper operation and regular maintenance are key for your Pentair pool heater. Follow these best practices for peak heating function.

Prioritize Efficiency

For maximum efficiency, set your Pentair heater’s thermostat precisely to your ideal pool temperature instead of much higher. This avoids overheating the water further than required. Limit how often your heater cycles on and off each day – longer continuous runtimes conserve energy.

Also, add a pool cover at night and during cold weather. This greatly reduces heat loss from the surface so your Pentair heater doesn’t work as hard reheating cooled water. Automatic pool covers work best for convenience.

Clean Fins and Coils

Over time, airflow can suffer from a buildup of debris, leaves, pollen, etc stuck to heater fins and coils. Carefully vacuum and brush accumulated gunk from heat exchangers using a soft brush attachment. Avoid damaging delicate aluminum fins.

You’ll also want to confirm water chemistry balances like pH stay in recommended ranges. This prevents mineral scale accumulation that reduces heat transfer over time. Consider a pool maintenance service for periodic cleaning if upkeep proves difficult.

Inspect Connections and Components

Visually check around the outer cabinetry, vents, wiring, and plumbing for leaks, abnormal corrosion, cracks, or combustion exhaust issues. Confirm gas line valves function properly and don’t leak. Inspect for insect or rodent nests clogging areas. Tighten loose parts and replace damaged components as needed.

Following the recommended maintenance in Pentair manuals extends your heater’s lifespan for maximum return on investment. Don’t allow minor issues today to become major repair headaches tomorrow!

 

Troubleshooting Pentair Heater Problems

Even reliable Pentair heaters can occasionally suffer minor troubles or error warnings affecting function. Getting those problems promptly diagnosed saves headaches and costly emergency service calls.

Check Error Codes

Many Pentair heaters feature digital status displays indicating useful diagnostics. MasterTemp heaters, for example, use LED readouts corresponding to different issue types. Things like clogged filters, airflow disruptions, failed ignition attempts or tripped high limits may appear.

Consult Pentair’s manuals for specific error code details. Oftentimes, the source proves a quick and simple fix the owner can directly resolve following the listed steps. This avoids delays in waiting for a service tech.

Attempt Minor Repairs

For more complex repairs like control board replacements, check Pentair’s service manuals for detailed component testing procedures. Using a voltmeter and diagram tracing wires, an advanced DIYer may troubleshoot issues on their own when comfortable.

However, gas valve solenoids, igniters, combustion chambers, and pressure switch replacements often reside in the advanced difficulty category. Know your skill limits to avoid safety risks or improper installations.

Watch for Leaks

Pool owners should periodically inspect the heater for any drips or leaks of water or exhaust gases. Catching seal failures early prevents more severe deterioration needing pricier repairs later.

Wet spots might indicate loose plumbing fittings, cracked heat exchangers, eroded O-rings, or hole corrosion. Make sure condensation drains remain unobstructed also to prevent interior flooding.
