I need to use ^more^ electricity
Hi. I’d like some advice or suggestions. I’m in the lucky position of having to use more electricity. I have a solar pv tracker that generates about 5500 kwh/yr and I live in Vt where I cannot accumulate electricity $ credit for more than a year. My house is a New England Cape and I’ve done some energy conservation and efficiency measures during the last 15 years. I currently use about 4400 kwh/year and I hope to reduce that number over the next year. I already have an electric oven, stovetop and dryer. My oil boiler system (Energy Kinetics) is less than 20 years old and in great condition. My domestic hot water is indirect off the boiler and is a 4-year old Superstor 45 gallon tank. I have a Subaru that is not in need of replacement.
So I am unsure of the best way to reduce my oil or gasoline use and use more electricity. I’ve thought about buying a 110-volt stand-alone electric heater and running it somewhere in the house. I’ve thought about replacing my dhw system with a heat pump hot water heater, but I’m not convinced it will be more efficient during winter months when the boiler is running anyway to heat the home; and I don’t feel right trashing a perfectly good Superstor that has many useful years left.
I am thinking most strongly about a Nyle Geyser RO add-on hot water heat pump that is designed to heat the water in my existing tank, and if demand exceeds the heating capacity of the Nyle, then the oil would kick in as a backup.
I am wondering if anyone has experience with the Nyle and/or other ideas. I have read Marc Rosenbaum’s posts from a few years ago about the Nyle, and I know he wasn’t that pleased with it, but I think the units have gotten better since then. Thanks for any advice or wisdom. AndyVt
