All products at Reimers are ASME and UL authorized for labeling. These agencies visit unannounced frequently and validate quality and performance. Reimers has held approvals from them for decades. With thousands of electric boiler systems in the field Reimers has honed internal assembly and quality methods quite well. Electric immersion elements provide energy to the water without the need of fuel tanks or chimneys. Lower cost to install, faster install, and quieter are traits of Reimers boilers.
