Pentair Pool Heater Specs — BTU Ratings & Efficiency Table
Pentair pool heater datasheet summary: model-by-model BTU ratings, efficiency and COP from official sources, linked line by line — with sizing context against the industry formula.
Quick answer
Pentair's published heater lineup covers 7 models across 3 product lines (gas, heat pump), spanning 140,000 to 400,000 BTU/hr. Gas models are rated by fuel input — divide by the stated efficiency (82% federal floor at minimum) for the heat actually delivered. Heat pump figures are delivered heat output, rated at warm-air test conditions. Check any model against your pool's requirement with the BTU calculator.

Pentair keeps the lineup focused on 2 fuel paths rather than spreading across every category — the table below is short enough to compare against your required BTU in one read.
Every figure below traces to an official Pentair source (linked per table); anything the sources don't state is marked "(to be verified)" rather than guessed. To see whether a given BTU rating fits your pool, run the BTU calculator first.
Pentair MasterTemp (Natural gas)
Five input classes 175k-400k BTU/hr in NG and propane; copper standard, HD cupro-nickel option.
| Model | Rated BTU/hr | Efficiency / COP | Notes |
|---|---|---|---|
| MasterTemp 175 (460792) | 175,000 input | (to be verified) | Natural gas item 460792 / propane 460793. |
| MasterTemp 200 (460730) | 200,000 input | (to be verified) | ASME variant 461000; propane 460731. |
| MasterTemp 250 (460732) | 250,000 input | (to be verified) | ASME variant 460771; 250HD cupro-nickel 460806. |
| MasterTemp 300 (460734) | 300,000 input | (to be verified) | Propane 460735. |
| MasterTemp 400 (460736) | 400,000 input | 84% | 84% thermal efficiency with standard copper exchanger; HD cupro-nickel variant 82% (460805). ASME 460775. |
Pentair UltraTemp (Heat pump)
Heat-pump-only line in four sizes with titanium exchangers.
| Model | Rated BTU/hr | Efficiency / COP | Notes |
|---|---|---|---|
| UltraTemp 90 / 110 / 120 / 140 | 140,000 output | (to be verified) | Four sizes 90K/110K/120K/140K BTU/hr (largest 140,000 listed here); titanium heat exchanger. Per-model detail (to be verified). |
Pentair UltraTemp ETi Hybrid (Heat pump)
Dual-fuel hybrid: heat pump + gas heater in one cabinet, four operating modes (heat pump / gas / dual / hybrid-auto).
| Model | Rated BTU/hr | Efficiency / COP | Notes |
|---|---|---|---|
| UltraTemp ETi 220 (460969) | 220,000 output | (to be verified) | Up to 220,000 BTU/hr combined (dual mode); up to 193,000 BTU/hr at 80°F/80% RH test condition; dual titanium heat exchangers; up to 120 GPM. |
How to read these specs against your pool
Gas-fired models in the table are rated by fuel input — the heat that reaches your pool is at least 82% of that (federal floor, 10 CFR 430.32), and datasheet efficiency figures may be higher. The sizing guide shows how to convert.
Heat pump ratings are heat output at warm-air test conditions; real output falls with air temperature, so shoulder-season swimmers size one step up. The heat pump vs gas calculator prices the difference at your rates.
Three practical checks before buying: first, confirm the required capacity with the BTU calculator (wind, shade and a solar cover move it); second, match the rating type — don't compare a gas input figure against a heat pump output figure; third, verify the exact model against the official Pentair datasheet and your installer's gas-line or electrical assessment, because installation constraints, not the spec table, decide what can actually be connected.
Then estimate what the model costs to run in the running cost calculator. This page is independent — no affiliation with Pentair; brand names are trademarks of their owners.
FAQ
Where do these Pentair specifications come from?
Every figure is captured from Pentair's own published material — official product pages, datasheets and installation manuals — with the source link shown under each table and a capture date. Nothing on this page comes from retailer listings or third-party claims about Pentair products.
Why do some fields say "(to be verified)"?
When Pentair doesn't publish a number for a field (a COP value, for example), this page leaves it marked "(to be verified)" instead of estimating it. The missing figure changes nothing about the ratings that are published — and the BTU calculator works from capacity, which every model states.
How do I compare Pentair with another brand?
Compare the same rating type: input BTU/hr against input, output against output, and convert gas input to delivered heat at the stated efficiency. All brand pages on this site follow the same table format from the same capture discipline, so brand pages are directly comparable — that is the point of running them on one neutral site.
