What the price includes
An installed price covers the heater, labor and basic hookups. HomeGuide says the unit alone runs $1,000 to $4,000 or more. A new gas line, plumbing changes and an electric circuit are often extra. Monthly running costs are not part of the price. Ask if the quote includes a pad, permits and haul away of an old unit. It does not include tax or extras the provider adds on the day.
DIY or hire a pro
Pool heater work mixes gas, water and electric lines, so most people hire a pro. A bad gas hookup can be unsafe, and an error in the wiring can start a fire. Many towns also require a permit. A solar panel kit can be a DIY job for a handy owner, but the plumbing still needs care. Labor runs $500 to $1,170 on HomeGnome, which is a small part of the bill compared with the risk. Ask the pro to check your pool pump and the pipes first.
How to tell you need it
You may need a new pool heater if the water will not warm up, the unit makes loud noises, or it shuts off on its own. Rust, leaks and a high gas or power bill are also signs. HomeGuide says gas heaters last 7 to 8 years. Ask a pro to check for a simple repair before you buy a new unit.
How to judge your quote
- Ask for the unit, labor and hookups on separate lines.
- Ask the monthly running cost for your pool size.
- Ask if a gas line, plumbing or an electric circuit is extra.
- Ask how long the heater lasts and what the warranty covers.
- Compare the total with the range above: $1,500 to $5,200 per job for most people in 2026.
Ways to pay less
- Compare running costs, not only the sticker price. HomeGuide lists heat pumps at $50 to $150 a month against $200 to $500 for gas.
- Get at least three quotes and ask for the unit, labor and hookups listed on separate lines.
- Pick the right size for your pool. HomeGnome lists unit prices from $1,300 for small pools to $5,000 for large ones.
- Add a pool cover to keep heat in, which lowers how hard the heater has to work.
- Ask about install in the off season, when pool pros may have more open time and may give a better price.
Why this costs more in 2026
Trade labor now runs about $75 to $150 an hour in most of the US. Lumber, steel, copper, PVC and concrete all cost more than in 2024, and freight went up after the oil shock that began with the Iran war in February 2026. A heat pump can cost up to $8,000 installed in 2026 per Swimply, and that higher up front price is a big part of why pool heater bills run high.
