Is Rheem water heater any good?
Yes — Rheem water heaters are a premium-tier choice. Our installers rate the lineup 4.8/5 based on real Long Island installs. Rheem is manufactured by Rheem Manufacturing, which means shared parts and proven engineering. For most Long Island homes the bigger factor is installation quality — a properly sized, properly commissioned Rheem will outperform a poorly installed premium brand every time.

Expert Review: Rheem
First-hand experience from our Nassau County water heater installation team.
Our Field Experience with Rheem in Nassau County
As Homets Air & Heat, we’ve been installing and servicing water heaters across Jericho and wider Nassau County for years. When it comes to Rheem, our experience has been overwhelmingly positive. Their reputation as an industry leader is well-deserved, and we've found their units to be consistently reliable and robust. We appreciate the excellent parts availability on Long Island, which makes servicing straightforward and keeps our customers' downtime to a minimum. From standard tank models to their advanced ProTerra hybrid heat pump line, Rheem offers a solution for nearly every home and budget, even if it leans towards the premium end.
Handling Long Island's Hard Water and Coastal Conditions
Long Island’s water, particularly in Nassau County, is known for its hardness. This can be a significant challenge for water heaters, leading to sediment buildup and reduced efficiency over time. Rheem water heaters are built with durable components that stand up well to these conditions. Many models feature self-cleaning elements or have anode rods designed to combat corrosive elements. Furthermore, the coastal environment and fluctuating temperatures here demand resilient equipment. Rheem
