EndoTherm is an energy saving additive for hydronic heating and chilled systems (non-potable) which is proven to reduce energy consumption by 10-15%. It works by reducing the surface tension of the system water which improves heat transfer, creating a condition that is optimal for efficiency gains in the HVAC system. Buildings hit temperature setpoints quicker and systems are required to run less frequently to maintain temperature, saving significant amounts of energy.

Most HVAC systems use water or a glycol/water mixture as a heat transfer medium to provide either heating or cooling to a building. Water is used because it is cost effective and readily available, however it is not the most efficient transporter of heat due to the high surface tension. When added to the system water, EndoTherm improves the heat transfer characteristics of the fluid which allows more heat to be delivered  or exhausted from the building and thus reducing overall heating/cooling costs and CO2 emissions.

The University of British Columbia found that EndoTherm increased the temperature difference (ΔT) between the water leaving the heat exchanger and the water returning back to heat exchanger by 15%. The improvement in ΔT meant the building could now extract and deliver more heat from the district energy system and reach previously unattainable temperature set-points.

Vancouver International Airport saves 17.32% with EndoTherm

In 2017, PACE treated the South Terminal at the Vancouver International Airport (YVR) with EndoTherm to improve heat transfer and efficiency. The result was 17.32% reduction in boiler natural gas consumption and greenhouse gas emissions. YVR's EndoTherm case study was recently reviewed and published by the Building Energy Innovators Council (BEIC). The project had full payback in the first year, reducing natural gas consumption by 432.49 GJ. This gas reduction cut greenhouse gas emissions by 25.98 tonnes of CO2e which is equivilant to removing the emissions of 5.6 cars per year. 

Optional Equipment:

Pace Automated Feed System to maintain the recommended concentration of EndoTherm

 The PACE Automated Feed System is a PACE Solution! We recommended installation in larger systems or remote sites in order to help maintain ideal concentrations of EndoTherm and achieve peak efficiency. Installing this technology monitors system water loss and automatically adds additional EndoTherm to continuously maintain heat transfer performance and maximize energy savings. The PACE Automated Feed System can be connected to a cloud-based server to track consumption and provide low level and water loss alerts in real-time.
