The Bottom Line

Rheem makes quality boilers that are durable, reliable, and backed by a good warranty. They have both natural gas and propane versions available, so they’re suitable no matter where you live.

All the models are high-efficiency, with 95% or 96% AFUE ratings, and are ENERGY STAR rated. As such, these units are eligible for most of the rebates that are available.

However, Rheem doesn’t have a lot to offer in terms of selection. But the models they do have, however, have cost-saving efficiency ratings and easy-to-install features, so you can expect to save money with a Rheem boiler. 

Rheem Boiler Reviews from Real Customers

Most consumers we’ve heard from have good things to say about Rheem boilers. They like that they are quiet, reliable, and run well. They also have good features, such as the built-in safety features, and they’re energy efficient, so they can help reduce heating costs compared to an older system.

Rheem Average Boiler Price Range

$2,000 – $5,000+ (including installation)

Here at Furnace Prices, we know how important it is for you to be able to budget for a boiler upgrade. While we can’t give you an exact quote, we can tell you Rheem is mid-range in terms of budget.

The reason we can’t give a quote is because so many things impact the cost of a new boiler, including:

• Installation (the cost will also fluctuate based on the following factors)
• Your location
• The infrastructure and design of your home
• The boiler brand, make, and model
• Boiler type (such as conventional versus combi)
• Zone requirements
• AFUE rating

There is one way you might be able to save on your boiler purchase, and that’s through rebates. From time to time, the government, utility companies, HVAC distributors, and manufacturers offer rebates, particularly on high-efficiency boilers. Always check what deals and rebates are available before purchasing.

The best way to ensure you get the most bang for your buck is to invest in an ENERGY STAR boiler, which will use 10% less energy than a standard boiler. Most Rheem boilers are certified, with the exception of one or two sub-models.

Rheem Boiler Options Reviewed

Rheem High-Efficiency Gas Combi Boilers

The Rheem Prestige is Rheem’s option for a combi boiler, so it provides both heat and domestic hot water. Combi boilers can be a wise investment because they combine two appliances in one, reducing the purchase price, installation costs, and maintenance costs.

Rheem High-Efficiency Condensing Boilers

Until the ThermaForce™ boilers were released, Rheem didn’t have any heat-only boilers available or any condensing boilers. Luckily, the ThermaForce™ boilers come in heat-only condensing sub-models. That means each unit is equipped with a secondary heat exchanger that reuses exhaust gasses to extract more energy from them. These boilers are highly efficient.

Rheem High-Efficiency Condensing Combi Boilers

ThermaForce™ boilers are also available in condensing combi sub-models that provide both heat and domestic hot water. Condensing combi boilersare highly efficient and compact, so they’re great for smaller spaces.

Rheem Exclusive Features

Feature 1 – Auto Boost

The auto boost feature is a technology that comes standard with every Rheem combi boiler. This feature will boost the hydronic loop when the thermostat setting isn’t reached quickly enough to ensure your home gets to the right temperature as soon as possible.

With the auto boost feature, you never have to worry about your home getting cold because the boiler can’t keep up when the mercury drops or you turn up the heat.

Feature 2 – Safety Features

Along with dependability and quality, one of the major things Rheem focuses on is consumer safety. That’s why every one of their boilers is equipped with numerous safety features, including:

• Overheat cut off limit switch
• Flame sensor
• Exhaust thermistor
• Pressure sensor
• Gas leak detector
• Water leak detector
• Heating supply thermistor

Rheem’s Boiler Warranty

No Rheem boiler review would be complete without discussing the warranty coverage.

There are two main reasons you want to pay attention to a boiler warranty: for one, a good warranty could save you plenty of money in repair and maintenance costs. If you’re lucky, then your boiler won’t ever need repairs, but even well-made components can fail, and the warranty will protect you in that event.

And that brings us to the other reason warranties are important: they tell you how much faith the manufacturer puts in their products. A manufacturer that backs their boiler with a good warranty does so because they don’t expect any major problems during the warranty period. In other words, a 10-year warranty is similar to the manufacturer saying they expect the boiler to be reliable for at least that long.

So what do Rheem warranties look like? They’re among the best on the market, thanks in part to their industry-leading labour warranty. Rheem backs all of their boilers with the following warranties:

• A 10-year warranty for the heat exchanger
• A five-year warranty for parts
• A one-year labour warranty

Not all boiler manufacturers provide labour warranties, so this is a nice perk from Rheem.
