Getting a pool heater installed can feel confusing when you’re not sure who to call. Last month, my neighbor spent three weeks calling different contractors because nobody could agree on who should handle her gas pool heater installation. She ended up needing both a plumber AND an electrician to get the job done right.The truth is, pool heater installation usually requires multiple trades working together, but the main installer depends on what type of heater you’re getting. Gas heaters typically need plumbers for the gas lines, electric heaters need electricians for the wiring, and heat pumps often require HVAC specialists. Pool contractors can sometimes handle everything, but they usually subcontract the specialized work anyway.Most homeowners don’t realize that pool heater installation isn’t a one-person job. You’re dealing with electrical connections, gas lines (for gas heaters), water circulation, and sometimes even permits. The key is finding someone who can coordinate all these moving parts or knowing exactly which specialist to call for your specific heater type.Pool heater installation also varies significantly by region. In colder climates like Minnesota or Colorado, gas heaters are more common because they heat water faster. In warmer areas like Florida or California, heat pumps dominate because they’re more efficient when outdoor temperatures stay above 50 degrees. Your local climate affects not just what type of heater you should get, but also which contractors will have the most experience with your specific needs.

Do Electricians Install Pool Heaters?

Electricians absolutely install electric pool heaters, and they’re actually required by electrical code in most areas for any electrical work. Electric resistance heaters and heat pump pool heaters both need proper electrical connections that only licensed electricians should handle.

Important: Pool electrical work requires special expertise due to safety concerns around water and electricity. Always use a licensed electrician with pool experience.

Here’s what electricians do during pool heater installation:Electrical Panel Work: They run new circuits from your main electrical panel to the pool equipment area. Most pool heaters need dedicated 220V circuits, which means new breakers and heavy-gauge wiring. Electric resistance heaters typically need 25-50 amp circuits, while heat pumps can require anywhere from 30-60 amps depending on their size.GFCI Protection: Pool equipment requires ground fault circuit interrupter protection by law. Electricians install GFCI breakers or outlets to keep your family safe from electrical shock. This isn’t optional – it’s required by the National Electrical Code for any pool equipment.Equipment Connections: They wire the heater unit itself, connect control panels, and make sure everything meets local electrical codes. They also install disconnect switches, which are required to be within sight of the pool equipment.Grounding and Bonding: Pool electrical systems require special grounding and bonding to prevent electrical shock. Electricians install copper bonding wires that connect all metal components around the pool area, including the heater, pump, ladder, and even rebar in concrete decks.

When Do You Need a Plumber for Pool Heaters?

Plumbers are absolutely necessary for gas pool heater installations, and they handle all the water connections regardless of heater type. If you’re getting a natural gas or propane heater, you legally need a licensed plumber or gas fitter to run the gas lines.

Gas Line Installation: Natural gas heaters need gas lines run from your home’s gas meter to the pool equipment area. This isn’t DIY territory – improper gas line installation can cause leaks, explosions, or carbon monoxide poisoning. Most gas heaters need 1/2″ or 3/4″ gas lines, depending on the BTU rating and distance from the meter.

Water Circulation Connections: All pool heaters, whether gas, electric, or heat pump, need to be plumbed into your pool’s circulation system. Plumbers install the bypass valves, unions, and pipe connections that let water flow through the heater. They also install temperature and pressure relief valves required by code.

Drainage and Ventilation: Gas heaters produce condensation and need proper drainage. Plumbers install condensate drains and make sure there’s adequate clearance for combustion air. Poor ventilation can cause the heater to shut down or operate inefficiently.

Some areas require separate licenses for gas work versus water plumbing. Make sure whoever you hire has the right credentials for gas line installation if you’re getting a gas heater. The gas company usually needs to inspect and turn on service after installation too.

Pool Contractors vs Specialty Trades

Pool contractors often advertise that they can handle complete heater installations, and many can. However, most subcontract the electrical and gas work to licensed specialists. This can actually work in your favor because you get one point of contact who coordinates everything.

Advantages of Using Pool Contractors: They understand pool systems better than general contractors. They know proper sizing, optimal placement, and how heaters integrate with pumps, filters, and automation systems. Pool contractors also handle permits and inspections, which saves you time.

Potential Drawbacks: You’re paying markup on subcontracted work. If there’s an electrical or gas problem later, you might end up dealing with multiple parties to get warranty service. Some pool contractors aren’t as experienced with the latest heat pump technology.

HVAC Contractors and Heat Pumps: Heat pump pool heaters are basically air conditioning units in reverse. Many HVAC contractors are more experienced with heat pump technology than traditional pool contractors. They understand refrigerant systems, defrost cycles, and troubleshooting heat pump specific issues.

The best approach often depends on your specific situation. If you’re just replacing an existing heater with the same type, a pool contractor might be most efficient. If you’re switching heater types or adding heating to an existing pool, you might want to hire trades directly.

Different Heater Types Require Different Professionals

Gas Heaters (Natural Gas or Propane): Require plumbers for gas lines and water connections, electricians for controls and ignition systems. Gas heaters are still the fastest way to heat a pool, raising temperature 1-2 degrees per hour. They work efficiently in any weather but cost more to operate than heat pumps.

Electric Resistance Heaters: Need electricians for installation and usually pool contractors for water connections. These are becoming less common because they’re expensive to operate, but they’re reliable and work in any temperature. They’re often used as backup heaters in northern climates.

Heat Pump Heaters: Best installed by HVAC contractors or pool contractors with heat pump experience, plus electricians for power connections. Heat pumps are 3-5 times more efficient than electric resistance heaters but only work effectively when air temperatures are above 45-50 degrees.

Solar Pool Heaters: Usually installed by specialized solar contractors or pool contractors. They need roof work for collector mounting, plumbing for water circulation, and sometimes electrical for pumps and controls. Solar heaters have the lowest operating costs but are weather dependent.

Hybrid Systems: Some homeowners install combination systems, like a heat pump for everyday heating plus a gas heater for quick temperature boosts. These complex installations definitely need coordination between multiple trades.

But here’s the thing – electricians typically don’t handle the plumbing connections or the heater mounting. They focus on the electrical side while plumbers or pool contractors handle the water lines and equipment positioning.Electric heat pumps are becoming super popular because they’re energy efficient, but they need bigger electrical service than regular electric heaters. Some heat pumps draw 50+ amps, which might mean upgrading your main electrical panel. That’s definitely electrician territory.If you’re getting an electric pool heater, start with a licensed electrician who has pool experience. They can tell you if your electrical system can handle the new load and what permits you’ll need. Don’t let just anyone touch pool electrical work – water and electricity don’t mix, and the consequences can be deadly.Common Safety Violations: Unlicensed handymen often skip GFCI protection, use incorrect wire sizes, or install equipment too close to the pool. These violations can be deadly and will fail inspection. Always verify licensing and insurance before hiring anyone for pool electrical work.Carbon Monoxide Risks: Gas heaters produce carbon monoxide, which is odorless and deadly. Proper installation includes adequate ventilation and clearances from doors, windows, and air intakes. Some areas require carbon monoxide detectors near gas pool equipment.

Cost Factors and Budgeting

Pool heater installation costs vary wildly depending on your situation. A simple electric heater replacement might cost $800-1,500 total, while a new gas heater installation with gas line trenching can hit $3,000-6,000 or more.

Electrical Work Costs: Running new 220V circuits typically costs $300-800 depending on distance and panel upgrades needed. Panel upgrades can add $1,000-3,000 to the project. Get electrical quotes early because this work often takes the longest to schedule.

Gas Line Installation: New gas lines cost $500-2,000 depending on distance and trenching required. If your gas meter needs upgrading for higher BTU demand, add another $500-1,500. Underground gas lines require locating utilities and getting permits.

Equipment Costs: Gas heaters range from $1,500-4,000, electric resistance heaters cost $1,000-3,000, and heat pumps run $2,500-6,000. Higher efficiency units cost more upfront but save money long-term on operating costs.

Labor and Permits: Installation labor typically runs $500-1,500 depending on complexity. Permits cost $100-500 in most areas. Some jurisdictions require separate electrical, gas, and building permits.

Get quotes from multiple types of contractors to compare total project costs. Sometimes hiring trades directly costs less than using a general contractor, but you lose the convenience of single-point coordination.

The electrical work usually takes 4-6 hours for a straightforward installation, but it can take longer if you need panel upgrades or if your pool equipment is far from the house.Typical Installation Timeline: Simple replacements take 1-2 days, while new installations can take 1-2 weeks. Gas line installation often takes longest because it requires utility locating, trenching, and gas company connection. Electrical work usually happens first, followed by gas lines, then final heater installation and startup.Permitting Delays: Permits can add 1-3 weeks to the timeline in busy jurisdictions. Some areas offer expedited permitting for an extra fee. Submit permit applications early to avoid delays during peak pool season.Weather Considerations: Outdoor work gets delayed by rain or extreme temperatures. Plan installations during shoulder seasons (spring or fall) when contractors are less busy and weather is more predictable.Equipment Availability: Popular heater models sometimes have long lead times, especially during spring pool opening season. Order equipment early or have your contractor check availability before starting work.

How to Choose the Right Contractor

Choosing the right contractor makes the difference between a smooth installation and a nightmare project. Here’s what to look for when hiring pool heater installers:

Licensing and Insurance: Verify that electricians have electrical licenses, plumbers have plumbing licenses, and gas fitters have gas certifications. All contractors should carry liability insurance and workers compensation. Ask to see certificates and verify with licensing boards.

Pool-Specific Experience: General electricians and plumbers might not understand pool codes and requirements. Look for contractors who regularly work on pool equipment. Ask about recent pool heater installations and request references.

Written Estimates: Get detailed written estimates that break down equipment, labor, permits, and materials. Avoid contractors who give verbal estimates or demand large upfront payments. Good contractors typically ask for 10-25% down with the balance due on completion.

Manufacturer Certifications: Many heater manufacturers offer training programs for installers. Certified installers often provide better warranty coverage and know the latest installation requirements for specific brands.

Local References: Ask for references from recent local installations. Contact previous customers about work quality, timeline adherence, and problem resolution. Good contractors are proud to share their work history.

Communication and Professionalism: Pay attention to how contractors communicate during the estimate process. Do they return calls promptly? Do they explain options clearly? Are they on time for appointments? These behaviors predict how they’ll handle your project.
