Rheem RTG-84DVP Low Nox Direct Vent Tankless

Review of Rheem RTG-84DVP Low Nox Direct Vent Tankless Water Heater Liquid Propane Energy Star 8.4 GPM

When it comes to taking care of a household, finding the most affordable tools for living a good life is one of the many challenges to deal with. It’s easy to install a traditional water heating system with a tank, but your bill is always going to be a burden.

The tankless water heating systems were created, especially for cutting down your spending. They give hot water on demand and are a wise addition to any household or even commercial applications.

What is it that tankless water heaters bring to the table?

Even if the lower energy use and the lower energy bill are the main advantages of tankless water heaters, there are plenty of other aspects to consider.

If you’re always struggling with storage space, a tankless water heater is going to be an excellent choice for your household. There’s no tank to find a storage space for. Therefore it’s always easy to find the right place for it.

Since the tankless water heaters heat water on demand, the water doesn’t stay in the system. The risk for calcium and magnesium in water to damage the system is lower, which makes the tankless water heaters more durable than the traditional competitors. However, if you have hard water, using a water softener is going to benefit even the tankless water heater.

No tank also means less maintenance and most tankless water heaters only require flushing once a year or even less than that.

Some may feel that the tankless water heaters are pricey (it’s typically the strong gas/LP models that are pricier). However,  they’re always a good investment in the long run.

How to describe Rheem RTG-84DVP Low Nox Direct Vent Tankless in a few words?

Whether you go with electric or gas models, tankless water heaters are always going to cut down your spending. Having said that, let’s start by highlighting that Rheem RTG-84DVP Low Nox Direct Vent Tankless is running on LP (liquid propane). It’s designed for residential applications and heats water on demand for many years to come.

Not only that, the tankless water heater is one third the size of a traditional water heater, but it’s also reliable and energy-efficient. The innovative technology on the unit resulted in a small water heater that doesn’t disappoint with the features or performance. Operating the unit is straightforward, whereas the compact size allows installing for a water softener or wins you more storage space for something else.

Which technical specs impress us the most?

Don’t let the small size of the unit fool you since Rheem RTG-84DVP Low Nox Direct Vent Tankless is reliable. It provides 8.4GPM at 35A-degree F rise max. It gives 6.6GPM at 45-degree F rise and comes with 3”/5” concentric vent system featuring built-in condensate collector.

The minimal flow for activating the water heater is .26GPM, whereas the minimum activation flow rate is .40GPM. It’s an impressive 180,000BTUs input for the unit, which makes it strong enough for sustaining a dishwasher, a shower, and a washing machine simultaneously.

The unit comes with UMP-117 remote control, which eases out the operation from a distance. You get 10ft of thermostat wire, which should be enough for most household applications.

Not only that, you can operate the unit from a distance, but you can also check the water temperature or status at a point due to the digital display. It’s a user-friendly digital display that helps you set the temperature and take a look at the unit’s status from time to time.

Installation shouldn’t be complicated, especially if you have the plumbing experience. Keep in mind that you need to buy a vent termination kit for proper installation, as well.

It’s a self-protective system that is built in the unit, protecting it against overheating. The next generation burner technology used for the water heater explains the high performance and energy efficiency. The Rheem RTG-84DVP Low Nox Direct Vent Tankless follows the low nitrogen oxide emission standards too. Thanks to its build, safety features, and overall performance, the water heater is also eligible for federal tax credits.

  • It doesn’t come with installation vent kit
  • You may void the warranty if not installing it by a professional plumber
  • The customer service could be more helpful and more willing to help
  • It’s made for LP, so you cannot convert it for gas. However, there’s a similar model specially designed for gas.
