Quick answer
AquaCal doesn’t sell one heat pump line called “HeatWave” — it sells three, and the names are close enough to cause real mix-ups. HeatWave (model prefix HW) is the standard-compressor line built for heating performance. HeatWave SuperQuiet (model prefix SQ) swaps in a scroll compressor and is rated at 55 dB, per AquaCal’s own marketing. TropiCal Inverter (model prefix T) is the newest line, using full inverter technology and R32 refrigerant across three sizes (T70, T100, T130). The confusion is real, not hypothetical: hvacdirect.com’s own product listing for model HW160ARDSBPA — the standard, non-scroll-compressor HeatWave — is titled “AquaCal Pool Heat Pump, HeatWave SuperQuiet - 128,000 BTU,” conflating the two lines in the exact listing a quiet-operation shopper would search for.
Three lines, one brand name
This site’s existing best AquaCal pool heater guide covers the SQ125, SQ160R, and SQ225 — all HeatWave SuperQuiet models. What it doesn’t cover is that AquaCal sells two other heat-pump lines alongside it, and the overlapping “HeatWave” branding is where a buyer can get tripped up.
| Line | Model prefix | Compressor | Noise | Refrigerant | BTU range |
|---|---|---|---|---|---|
| HeatWave | HW | Standard, high-speed fan | Not published | R410A | 128,000 (HW160) |
| HeatWave SuperQuiet | SQ | Scroll | 55 dB at 10 ft | R410A | 101,000-143,000 (SQ125-SQ225) |
| TropiCal Inverter | T | Variable-speed inverter | Not published (marketed as quiet) | R32 | 63,000-123,000 boost (T70-T130) |
AquaCal’s own HW160 brochure doesn’t publish a decibel figure at all — a real gap worth flagging, since the SuperQuiet line’s 55 dB rating is repeated across nearly every retailer page we checked, while the base HeatWave line’s noise level simply isn’t stated anywhere we found.
The mislabeling, confirmed on a live retailer page
Searching for “AquaCal HeatWave SuperQuiet” at hvacdirect.com turns up a product page for model HW160ARDSBPA, rated 128,000 BTU and priced $5,316, under the title “AquaCal Pool Heat Pump, HeatWave SuperQuiet - 128,000 BTU.” The model number’s “HW” prefix is AquaCal’s own designation for the standard-compressor HeatWave line, not the scroll-compressor SQ line the “SuperQuiet” name describes elsewhere in AquaCal’s literature. The same retailer’s broader AquaCal catalog page lists a separate SQ140ARDSBPA (114,000 BTU, $4,652) and SQ200ARDSBPA (138,000 BTU, $6,450) under the same “HeatWave SuperQuiet” title wording — so the retailer isn’t distinguishing the two lines by title at all, only by model number buried in the listing. If quiet operation is the reason you’re shopping, check the model prefix (SQ, not HW) before checking out, not just the listing title.
AquaCal HeatWave SuperQuiet SQ160R (128,000 BTU)
- Carries AquaCal's confirmed 55 dB rating and scroll compressor — the model to buy if noise is the deciding factor.
- Already this site's top AquaCal pick in our best AquaCal pool heater guide.

HeatWave HW160 — the standard-compressor line
AquaCal HeatWave HW160 (128,000 BTU)
- Same 128,000 BTU rating as the SuperQuiet SQ160R, built with a standard high-speed-fan compressor instead of a scroll compressor.
- AquaCal's own brochure for this model doesn't list a decibel figure — budget for a louder unit than the SQ line unless a dealer can confirm otherwise for your specific install.
The HW160 and SQ160R share an identical 128,000 BTU rating and a near-identical $5,316 price point in the listings we checked — so price alone won’t tell these two apart either. The only reliable signal is the model-number prefix itself.
TropiCal Inverter — the newest line, and the smallest
AquaCal TropiCal T130 Inverter (123,000 BTU boost)
- AquaCal's newest line, using full inverter technology that modulates output (36.0-18.5 kW on the T130) instead of cycling a fixed-speed compressor on and off.
- Runs R32 refrigerant, a newer refrigerant than the R410A used across both HeatWave lines — worth asking a local installer about availability before buying, since not every service tech stocks R32 parts yet.
- The published BTU figures (63,000/108,000/123,000 for T70/T100/T130) are boost-mode numbers, not a flat sustained rating — expect the unit to run below that peak output most of the time it's maintaining temperature.
TropiCal’s top size, the T130, tops out at 123,000 BTU boost — smaller than the HeatWave SuperQuiet SQ225’s 143,000 BTU, covered in our best AquaCal pool heater guide. If your pool needs more capacity than that, TropiCal isn’t the line to shop yet.
Which AquaCal line actually fits
For most buyers prioritizing quiet operation near a house or neighboring yard, stick to the SQ-prefixed HeatWave SuperQuiet line and double-check the model number on any listing titled just “HeatWave” — as the hvacdirect.com example shows, the title alone isn’t a reliable signal. If noise isn’t a deciding factor and price-per-BTU is, the standard HW-prefixed HeatWave line runs about the same price for the same output in the sizes we checked, so there’s little reason to pay extra for SuperQuiet branding without actually getting the scroll compressor. TropiCal is the one to watch for buyers who want inverter-driven efficiency and the newer R32 refrigerant, with the caveat that its largest size (T130) doesn’t yet match the biggest SQ or HW units on raw capacity.

The bottom line
“AquaCal HeatWave” isn’t one product — it’s a brand name shared by three distinct heat-pump lines (HeatWave, HeatWave SuperQuiet, and TropiCal Inverter) with different compressors, refrigerants, and (in HeatWave SuperQuiet’s case specifically) a published noise rating the other two lines don’t carry. At least one major retailer’s own listing title blurs the standard HeatWave line into the SuperQuiet name, so the model-number prefix — HW, SQ, or T — is the only detail worth trusting over the listing title itself.
