Quest PowerHeat CHH 300 Pro

The Quest PowerHeat CHH 300 Pro central hydronic heaters are CSA/UL certified and designed to operate on multiple fuel sources. The burners utilize proprietary technology to ensure smooth, clean, cold-weather ignition and steady burn efficiency. The Quest PowerHeat CHH 300 Pro is tri-fuel and a burner change is all that is required to convert from one fuel type to the other. All exposed components on PowerHeat CHHs are made of non-corrosive stainless steel and aluminum — no expensive refurbishment required. Unlike competitive units, the Quest combustion chamber is 100% stainless steel, making it corrosion-free as well, even when running in low temp applications.


British thermal unit (BTU) is an energy unit used to measure thermal energy needed to heat or cool spaces.
