Cost to Install a Pool Heater

Installing a pool heater means matching a unit to the pool’s plumbing flow rate, setting it on a level site near the filter, then connecting PVC piping and electrical components. Homeowners may take this on when adding or replacing pool heating, but selecting a compatible unit and completing the electrical work make this a hard installation.

Common reasons homeowners do this job

  • Adding a heater suited to the pool’s size and climate.
  • Replacing a worn or damaged pool heater.
  • Correcting a mismatch between the pool’s plumbing flow rate and the heater.
  • Creating a suitable level location near the filter for a heater.
  • Updating the PVC plumbing and electrical connections needed for a heater installation.

DIY or call a pro?

A licensed professional should install a pool heater because the work requires high-voltage electrical connections that pose a shock risk. Electrical connections need to be properly grounded and weather-protected, and the plumbing must follow the heater manufacturer’s diagram. A professional should also handle electrical and gas components.

Frequently asked questions

Can I install a pool heater myself or should I hire someone?
Hire a licensed professional. This is a hard installation involving high-voltage electrical work and a risk of shock, along with PVC plumbing connections and heater placement near the filter.
What can make pool heater installation cost more?
The price can rise with the job’s size, labor time, materials, and haul-away of old material. Small jobs may also include a minimum or trip charge.
What should I check before choosing a pool heater?
Confirm the pool’s plumbing flow rate first, then choose a heater appropriate for the pool size and climate. Identify a level installation site close to the filter and approximately 25 feet from the pool before selecting the unit.
Why is a voltage tester used during pool heater installation?
A voltage tester is used to verify that electrical connections are safe and correct after wiring. Because the work involves high voltage, grounding and weather protection are essential.
