intellihot Brings Hot Water to New Heights

The second tallest luxury residential building in Chicago eliminates over 2,000 gallons of storage and saves 27% gas cost annually without sacrifcing comfort for its residents. 

340 On the Park is a 68-storey luxury condominium tower located next to the Millennium Park in Chicago, and was completed in 2007. It is currently the second tallest all-residential building in Chicago, with 68 floors, which houses 344 residential units, and these are a combination of multi-bathroom and multi-bedroom units. The first residential tower in the Midwest to achieve Silver LEED Certification for its “green” design, it also boasts a large winter garden for its residents. 


"We have been very pleased with the installation and performance of the system and proud to be at the forefront of demonstrating an energy-efficiency breakthrough in the building community. Any building that has a domestic hot water boiler capital project in the future should be considering Intellihot." - Amy Eickhoff, Building Manager

The Challenge

The previous water heating system consisted of two commercial 2 million BTU tank type heaters with over 2,000 gallons of storage. The units were located on the penthouse floor of the building and were in various stages of failure within 7 years. The labor and helicopter service necessary to replace the two boilers were not covered by their warranty.

The Intellihot Solution

Four iQ 1001 units were installed and cascaded together, to create a combined capacity of 4 million BTUs. Intellihot’s ingenious method of masterless cascading ensures high reliability along with limited down-time. Intellihot’s plug and play set up ensured a rapid change out without a need to re-balance the entire building.
