Heat pump and hybrid water heaters
Rinnai REHP80 80 Gallon Specifications
Researched from the DOE test procedures, NFPA 54 and NEC code tables, and manufacturer specifications. Updated .
Quick answer
This page collects what is actually published about the Rinnai REHP80 80 Gallon and shows what those figures produce, computed rather than transcribed. Anything the listing does not publish is not filled in with an estimate.
Published specifications
Everything here is taken from the listing or the manufacturer, and nothing is inferred.
| Specification | Value |
|---|---|
| Gallons | 80 |
| Fuel | Electric heat pump |
| Energy Star | Yes |
Published standard Source: Manufacturer listing data. A specification not listed here is one this listing does not publish. Check the installation manual for the full data plate.
Why there is no performance table on this page
This listing does not publish an input rating in BTU per hour or in kilowatts, and without one there is nothing to compute a flow rate or a recovery rate from. Estimating it from the price or from the physical size would produce a confident number with nothing behind it, so this page does not.
The installation manual for this model publishes the input rating on its data plate. Once you have that figure, the recovery rate calculator and the tankless sizing calculator will do the rest.
How it sits against the rest of its category
Other heat pump and hybrid water heaters in this catalog: Senville Hybrid Heat Pump 50 Gallon, Rinnai REHP50 50 Gallon, ACiQ 50 Gallon Hybrid, Rinnai REHP65 65 Gallon.
Compare them on input rating and on the figures the manufacturer actually publishes rather than on the headline number in the listing title, which in this category is frequently a maximum measured under conditions the listing never states.
Other heat pump and hybrid water heaters
Senville Hybrid Heat Pump 50 Gallon
$1,099.99The lowest price of entry into a heat pump water heater in this catalog, and Energy Star listed, which means its efficiency figure was measured against the DOE test procedure rather than claimed.
Best for: A first heat pump water heater in a warm garage or basement

Rinnai REHP50 50 Gallon
$1,799.00A 50 gallon heat pump tank from a manufacturer with an established residential service channel, which is the part that decides what year eight looks like.
Best for: The standard 50 gallon replacement, done properly

ACiQ 50 Gallon Hybrid
$1,799.99A hybrid runs its compressor most of the time and falls back to resistance elements on a heavy draw, which is why a hybrid never simply fails to make hot water.
Best for: Households unwilling to risk a slow recovery

- What are the specifications of the Rinnai REHP80 80 Gallon?
- The listing publishes gallons, fuel, energy star and related figures, shown in full in the table on this page. Anything not shown is something the listing does not publish, and this page does not estimate it.
- Is this page based on hands-on testing?
- No, and we never claim otherwise. Everything here is compiled from the manufacturer listing, published specifications and the energy relations that turn those specifications into flow and recovery figures. We do not test products in person. Where a figure is not published, this page says so rather than estimating it.
- Are the prices on this page current?
- They come from verified catalog data at the time the page was built, and prices in this category move often. Treat any price shown as a guide and check the listing itself before deciding. Availability moves even faster than price does on water heater accessories in particular.
A water heater is a pressure vessel. The temperature and pressure relief valve is the one component on it that is never capped, plugged or removed, and a valve that will not open when you lift the test lever has failed and needs replacing rather than ignoring. If the valve weeps after the heater runs, that is thermal expansion in a closed system and the answer is an expansion tank or a pressure reducing valve, never a cap.
