Pool Heater-Chiller Units

A pool heater-chiller does both: heat in spring and fall, cool in summer. Every unit on this page handles both modes as standard: no add-ons, no upgrade required. The main decisions are pool size, budget, and whether you want an inverter compressor for lower running costs and quieter operation.

Choosing the Right Pool Chiller Heater Combo

Inverter vs. Standard Compressor

Standard single-speed compressors cycle on at full power and off — reliable, simple, lower upfront cost. Inverter compressors modulate continuously to match demand: quieter, more efficient at partial load, and meaningfully lower monthly running costs. For pools used frequently or in warm climates where the pump runs most of the year, an inverter pays back the price premium within one to two seasons.

For pools used frequently or in warm climates where the pump runs most of the year — Florida, Texas, Arizona — an inverter pays back the price premium within one to two seasons.

Every Madimack unit is a full inverter. FibroPool offers both (FH235-i and FH285-i are inverter; others are standard). AquaCal's TropiCal line is inverter; the SQ-R line is standard. GulfStream TA units are standard.

110V vs. 240V: Check Before You Order

The FibroPool FH120 and FH135 run on standard 110/120V — plug into any outdoor outlet, no electrician needed. Every other unit on this page requires a dedicated 220–240V circuit. If you don't have that run already, budget $300–$800 for an electrician before ordering.

Not sure what voltage you have? Check your breaker panel. A 240V circuit uses two breaker poles tied together. Pool heat pumps on 240V typically need a 30–60A dedicated breaker. Your electrician can confirm in under 10 minutes.

Pool Heat Pump with Chiller vs. Heat-Only: Which Do You Need?

A pool in direct sun can reach 90°F+ in summer in Florida, Texas, Arizona, and New York — too warm to swim in and hard on pool chemistry. A heater chiller combo lets you hold a target temperature year-round. Buying a pool heater and chiller combo upfront is cheaper than replacing a heat-only unit later, and most units here are priced comparably to their heat-only equivalents at the same BTU output.

Shopping heat-only? Units in the Pool Heat Pumps collection cost less upfront, but many of them are heat only and won't cool. If there's any chance you'll want cooling (especially in a warm climate), the heater-chiller is almost always the right call.
