Battery Backup for Gas furnace (boiler)
After the recent ice storm that disrupted the electrical grid in central NE, I would like to add an a battery Backup and inverter to my gas fired hot water heating system. Are any systems commercially available (why reinvent the wheel)? The power demand when running is less than 50 watts . A heating cycle runs about twenty minutes at a pop. The house is fairly energy efficient and the boiler only cycles about every two to three hours during the night. There is sufficient solar gain during a sunny winter day that the house gains heat during the day (3-4 degrees). Has anyone built of contemplated such an insurance policy? Naturally I would like to accomplish this project in as low a cost as possible. Any input would be appreciated.
