Start Your Pool Heater the Right Way This Spring
What Happens When Pool Heaters Sit Idle
Even high-quality heaters develop issues during long periods of dormancy.
Most of our customers report that they tend to stop using their heaters around July and may start them around December, but they say. “usually we really plan to start heating the spa or pool around March or April.”
This means that the majority of pool owners in the area leave their heater unattended sometimes for 7 months.
Florida humidity, dust, and debris slowly affect internal components.
Common startup problems include:
• Debris inside the unit
• Electrical terminal oxidation
• Restricted airflow through heat pump coils
• Insects or rodents nesting inside equipment
• Calcium buildup affecting heat exchangers
None of these are visible from the outside.
That’s why the first startup of the season is the most important moment for heater health.
SIGNS YOUR HEATER NEEDS A STARTUP CHECK
- HEATER HAS BEEN SITTING ALL WINTER
If it hasn’t been run for months, internal debris or corrosion may be present. - YOU HEAR CLICKING OR DELAYED IGNITION
- Startup problems often appear the first time the heater turns on.
- WATER TAKES MUCH LONGER TO HEAT
Efficiency problems often begin with restricted airflow or scaling.

Heater Operation FAQ
Many pool owners begin using their heaters again in March when warm days are followed by cooler nights.
Most residential pool heaters last:
• Gas heaters: 5–8 years
• Heat pumps: 8–12 years
Lifespan depends heavily on:
• water chemistry balance
• regular maintenance
• usage frequency
• salt exposure
• airflow conditions
Poor water balance, especially high calcium or low pH, can significantly shorten heater life.
Several issues can prevent a pool heater from heating properly. The most common causes include:
• Dirty filters restricting water flow
• Low water flow through the heater
• Incorrect thermostat settings
• Dirty burner chambers (gas heaters)
• Airflow restrictions (heat pumps)
• Scale buildup inside the heat exchanger
In Florida, heaters often sit unused for several months. When they start up again in spring, debris, corrosion, or airflow issues may appear.
In Florida, heaters often sit unused for six to seven months. During that time:
• debris collects in burner chambers
• electrical connections oxidize
• airflow passages gather dust
• insects may build nests in vents
A seasonal startup inspection helps ensure the heater operates safely and efficiently before relying on it.
Most residential pools are comfortable between:
82°F – 86°F
For spas, temperatures typically range from:
100°F – 104°F
Heating beyond these ranges can increase energy costs significantly and may shorten heater lifespan.
Both systems work well in Florida, but they serve different needs.
Heat Pumps
• lower operating cost
• best for maintaining steady temperatures
• ideal for Florida’s warm climate
Gas Heaters
• heat water quickly
• ideal for occasional use
• great for spas and quick warm-ups
Many homeowners choose heat pumps for everyday heating and gas heaters for rapid temperature increases.
