Description

This measure description covers the injection of a chemical additive into hydronic systems to improve the heat transfer efficiency in closed loop systems. Whilst the product can be installed into many thermal systems (heat pumps / chilled water) the initial UES measure proposal is for the main application into boiler systems. Hydronic additives can be used to manipulate waters heat transfer properties. These additives have been developed to improve the delivery of heat where and when it is needed to allow systems to react quicker to changes in demand; improve system delta-Ts; reduce run times and reduce wastage at the end of each system. This measure is DIFFERENT to oil-fouling and nano-technologies with different mechanisms and applications. We appreciate chemical additives are often met with skepticism but current market leaders are supported by academic studies, lab-based projects and 100s of case studies around the world. Chemical additives have been installed into 100,000+ buildings worldwide. Hydronic Additives is an active and approved UES in Canada with two fully prescriptive rebates in BC (FortisBC) and SK (SaskEnergy). Links to these have been provided below and references can be provided. FortisBC Prescriptive Rebate https://www.fortisbc.com/rebates/business/hvac-controls SaskEnergy Prescriptive Rebate https://www.saskenergy.com/ways-save/hydronic-additive-rebate-boilers FortisBC ran a 25 site pilot under their innovation demonstration program. The lowest achieved saving was 8.4% which became their adopted Energy Saving Factor (ESF). This ESF has been adopted by other programs including SaskEnergy and was also used in a first draft submission to the NY TRM. Hydronic additives are currently being reviewed by several NA utilities. UGI in PA offer a pre-approved rebate (ESF of 7.3%) whilst Consumers Energy in Michigan have just finished their 2nd year of pilot projects; the most recent a 3rd party pilot run by Franklin Energy at Corewell Health. Technical information on hydronic additives can be supplied upon request.
