December 1, 2020

diagramReplacing Your Current Unit with a Combi Boiler

A combi boiler is a great replacement for a tank water heater and traditional boiler. It’s compatible with any hydronic heating device, including radiant heat systems and the Rheem hydronic air handler. You’ll have an endless hot water system and a cozy home.

What a Space Saver

Combi units are major space savers. You can replace two larger units with this unit that hangs on the wall. It’s more efficient than the boiler and you’re getting the benefits of a tankless water heater.

Energy Efficiency Brings Energy Savings

This ENERGY STAR-certified unit has a 95% AUEF rating which means that it saves energy and may qualify for rebates. And since the unit only produces hot water when you need it, you’ll save energy and money. Check with your local utility company. 

Built-in Features

In addition to the standard features and functionality you will get from a combi boiler, the Rheem Prestige Combi Boiler also has a leak sensor that automatically detects a leak and closes the water or gas valve to stop a leak. With built-in controls and display, schedules and settings can be easily adjusted directly form the unit.

Outdoor Temperature Reset

One common issue when using a boiler is that the system can “over-heat” the home during spring and fall when the outdoor temperatures rise. The water temperature in the system is maintained at a constant, high temperature which can cause those in the home to feel warmer than desired.

The Rheem Prestige Combi Boiler includes an Outdoor Temperature Reset which tracks the outdoor temperature and automatically adjusts the temperature setting on the boiler function to keep the home at the desired set point while saving money during periods when it’s not as cold outside. It even has an auto-boost feature that makes sure that the temperature you set your thermostat at is achieved and speeds it up if needed. These features both combine to help keep the home at a steady and reliable temperature year round.
