Upgrade & Save is offered through the Connecticut Energy Marketers Association. CEMA understands that your new heating equipment is an investment in your future, and we want to make it possible for every local homeowner to enjoy the long-term savings that come with new, higher-efficiency heating equipment, and the peace of mind from a new, reliable aboveground oil storage tank. Research has shown that property owners with new, high-efficiency heating equipment are more satisfied with their comfort level and fuel choice. And comfort and satisfaction are what turns a house into a home. All Oilheated homes in Connecticut receive a Bioheat® fuel blend, per Connecticut statutes.
