Raypak® Hi Delta® Family Boiler Solutions

Did you know that as of 2023 atmospheric boilers will no longer meet DOE federal efficiency requirements?
As the Department of Energy continues to pass regulations promoting higher efficiency, atmospheric products such as the Raytherm™ boiler fall out of compliance.
Fortunately, we have a variety of solutions for your replacement boiler project needs! One of our lowest upfront cost solutions is our Hi Delta™ product family.
The Hi Delta product family was designed to be an easy transition over from the Raytherm. Hi Delta, is designed to be extremely versatile for retrofit projects. They are stackable via the SureRack™ kit, and available with the FlexGas™ dual fuel option.
The majority of Hi Delta connections such as water and gas are field reversible or can be ordered through Raypak to go on either side.
Compared to atmospheric boilers, the Hi Delta uses smaller diameter venting, which is often easier to install and reduces the overall venting material cost.
The Hi Delta product family consists of a range of control options, which includes our powerful VERSA IC platform featuring more intuitive controls, easy to read diagnostics, and cascading capability.
Hi Delta, is designed for easy serviceability making it a long-lasting product for your investment. It can withstand inlet temperatures down to 105ºF without condensation, which is an industry best in class.
Your replacement projects shouldn’t be more complicated than they already are. That’s why we’ve created the Hi Delta to make it a breeze. Here at Raypak we will be with you every step of the way!
