Should I rent my Rheem water heater or buy it?

Buying your Rheem tank is almost always the smarter financial move. Here is why renting doesn't make sense for a high-quality Professional Classic unit:

The Cost Trap: Over a typical 15-year rental agreement, you end up paying 6 times more than the actual cost of a Rheem Professional tank and installation.
Low Maintenance, High Quality: Because the Rheem Professional series is built with brass valves and a thicker tank lining, it is a low-maintenance, high-reliability unit. Paying a monthly fee for "protection" on a tank this durable is an unnecessary expense.
Escalating Fees: Rental contracts usually include price escalations every year, meaning your bill keeps going up while your Rheem tank gets older.

Contract Penalties: Most rental companies trap you in 15-year terms with massive penalties if you try to break the contract, move houses, or upgrade your system.

What is the difference between Rheem Performance (Home Depot) and Professional Classic series?

While they share the same core tank quality, the Professional Classic series is built for longevity and contractor-level performance. Key differences include:

Exclusive Labor Protection: Buying retail means you are responsible for finding and paying a plumber if anything goes wrong. With 4Most Energy, you get an exclusive one-year labor warranty on the installation.
Components: Professional models feature durable brass drain valves and metal-cased gas controls, whereas retail models often use plastic alternatives.

Support: Professional units are supported by licensed contractors who handle warranty exchanges directly, saving you from dealing with big-box customer service and long wait times for parts.

Can I use this for my floor heating?

Yes, select models in this series come with side water connections specifically designed for space heating applications. Ask us about a "Combination" setup.

What does "Induced Draft" mean for a power vent water heater?

In a power vent system, "Induced Draft" refers to the specialized blower assembly mounted on top of the tank. This motor mechanically "induces" a draft by pulling combustion gases through the heater and pushing them out through a plastic vent pipe. This allows for flexible horizontal venting through a side wall (up to 100-150 feet) rather than relying on a traditional vertical chimney.

We had a great experience with Rey and his team during our new Rinnai boiler installation. The technicians did an amazing job and worked efficiently. The technician Sam was knowledgeable, professional, and respectful throughout the installation. He took the time to answer all my questions and made sure everything was properly checked before finishing the job.

They arrived on time and completed the boiler installation on schedule.

We are very happy with the service and would definitely recommend them to anyone looking for reliable and professional HVAC service.

Thanks.

I was very pleased with the competitive pricing I got specifically from 4most energy. I contacted many companies to get their best quote. Sometimes there are even daughter or sister companies that will give you better quotes than the parent companies. It's best to check around for the identical product with installation from many companies. I was also pleased with the installers. They did have to cut away some insulation to install the Rinnai RX199 on the outside wall the house. Not sure if they should have tried replacing that insulation afterwards, but won't complain about the job they did because I think I got the best price on the market after getting quotes from about a dozen companies.

We recently had a Navien Combi boiler installed by 4Most Energy and had a great experience from start to finish. Rey was our sales representative and Sam was our technician, and both were excellent to work with.

They arrived on time, the installation was fast and efficient, and everyone was friendly and professional throughout the process. Sam did a great job with the installation, and everything is working perfectly.

We’re also very happy with the Navien Combi boiler itself. Overall, we couldn’t be happier with the service, the installation, and the product. We would definitely recommend 4Most Energy.

I contacted 4Most Energy to replace my 14 year old AC unit. Their intake process was smooth. They provided a reasonable quote the same day. The installation of the new AC unit was scheduled and the service provided by Farzad and his associate was completed within a reasonable time. They did a great job on the installation, hauled away the old equipment, and left the job site (both indoors and outdoors) in good condition. I would not hesitate to recommend 4Most Energy for your heating and cooling needs.

Great job Rey, Sam and team! My tankless water heater was broken for two months and after getting the run around from Enercare and Reliance, I decided on purchasing a Navien from 4Most Energy and they did a great job explaining the process and installing it the next day. Thank you for the top notch service!
