Rinnai REHP80 Heat Pump Water Heater
Tired of unpredictable electric bills from an inefficient water heater? The Rinnai REHP80 fixes it with heat pump technology that extracts ambient heat, delivering consistent hot water while drastically cutting energy consumption.
Why It Works
- High UEF of 4.00 directly tackles high operating costs, using up to 75% less energy than standard electric models.
- 91-gallon first-hour delivery solves the problem of running out of hot water for large households, supporting simultaneous showers and appliance use.
- Demand-Response Enabled addresses peak-hour energy surcharges by allowing utilities to shift its operation to lower-cost periods automatically.
- Zero-clearance design prevents installation headaches in tight mechanical rooms or closets where space is limited.
Trade-offs
- Higher upfront investment, but the operational savings and 10-year warranty justify the cost over its lifespan.
- Requires ambient air space, as performance can slightly decrease in very cold basement environments, though it remains functional.
The Rinnai REHP80 is worth it for households seeking the most efficient electric hot water solution. Its superior energy factor and robust delivery make it a definitive choice for solving cost and capacity problems long-term.

Rinnai REHP65 Heat Pump Water Heater
If you’re on the hunt for the best electric hot water heater 80 gallon capacity can offer, the Rinnai REHP65 deserves a long, hard look. This heat pump unit is a clever piece of engineering that basically steals warmth from your basement or utility room air to heat your water, which is as close to getting free hot water as I’ve ever seen. It landed at number two in our ranking because it masterfully balances massive output with serious energy sipping.
Pros
The efficiency story here is fantastic. That high Uniform Energy Factor of 3.90 isn’t just a number; it translates directly to lower bills, and being Energy Star Certified means it’s a proven performer. I was particularly impressed by its 80-gallon first-hour delivery, which means even a busy family won’t run out during the morning rush. The fact that it’s Demand-Response ready is a forward-thinking feature that could save even more money during peak grid times.
Cons
Your main consideration will be space and climate. Since it pulls heat from the air, installing it in a very cold space (like an uninsulated garage in winter) can reduce its efficiency. It also needs adequate air volume around it to function optimally, so a cramped closet isn’t ideal. While the installation is straightforward for pros, the upfront cost is higher than a standard electric tank, requiring a calculation of long-term savings versus initial investment.
Overall, the Rinnai REHP65 tells a compelling narrative of modern efficiency meeting household demand. It’s a set-it-and-forget-it workhorse that pays you back in reliable, abundant hot water and smaller utility statements month after month.

This compact unit, with its 10-gallon capacity and durable steel construction, is a game-changer for homeowners needing targeted hot water solutions in kitchens, cabins, or garages.

SmartJacket SJ-80 Water Heater Blanket
The standout feature of the SmartJacket SJ-80 is its 5mm polyethylene construction, which sets it apart from traditional fiberglass wraps. This blanket is engineered for 20 to 80-gallon electric or gas water heaters, offering an impressive R-value of 7.1. The material is inherently non-toxic and easy to clean, a significant practical advantage.
Key Advantages
- The non-fiberglass, polyethylene core eliminates the risk of airborne irritants during installation.
- Its high R-value of 7.1 directly targets standby heat loss, promising up to 40% improvement in thermal retention.
- The design promotes a rapid return on investment, often within a single heating season through reduced energy consumption.
Limitations
- The blanket does not provide custom shaping for unusually shaped or protruding tanks, requiring careful fitting.
- It is not a substitute for internal tank insulation and works best on older units with minimal existing jacket insulation.
The SmartJacket SJ-80 is ideal for homeowners with an older, 80-gallon electric water heater seeking a straightforward, non-toxic solution to curb energy bills. Its position in our ranking reflects its excellent balance of effectiveness, safety, and value for a standard tank upgrade.

ThermoMate 18-Gallon Electric Water Heater
If you’re searching for a compact, point-of-use solution rather than the best electric hot water heater 80 gallon for your whole house, the ThermoMate 18-Gallon Electric Water Heater deserves a close look. This unit is a specialist, designed to deliver hot water right where you need it, saving you from long pipe runs and the dreaded cold water wait.
Pros
The standout feature here is its intelligent design for tight spaces. The low 25.5-inch profile lets it tuck under sinks or into closets with ease. Its performance is robust for its size, reliably supplying a sink or a decent 20-25 minute shower thanks to the efficient INCOLOY-800 heating element. I’m particularly impressed by the thoughtful build quality; the porcelain enamel tank coating and comprehensive UL listing with a proper T&P valve signal a product built for safety and longevity, not just a quick install.
Cons
It’s crucial to manage expectations—this is not a primary whole-house heater. Its 18-gallon capacity is its limit, so simultaneous multi-fixture use will drain it quickly. The 120V hardwired requirement means it’s not a simple plug-in affair; professional installation is strongly advised to handle the electrical and plumbing connections safely, which adds to the upfront project cost.
Positioned at #5 in our ranking, the ThermoMate excels in specific scenarios like cabins, workshops, or as a booster for a distant bathroom. It’s a reliable workhorse that does its focused job very well.
