Hybrid Water Heater Review
One of the recurring joys of home ownership is plumbing. In 2021, the water heater in our home developed a small leak. Fortunately, the leak was small enough where we had some time to work out the next steps. Our long-term goal for our home is fully run on electricity for both comfort and climate reasons.
The domestic hot water system that existed in the home when we bought it used the indirect heating loop in the oil boiler and an unplugged electrical water heater as a storage tank. The boiler was setup to maintain a set point between 120F and 170F all year round. Looking at the summer usage of the boiler, we used between 0.5 and 1 gallon of oil per day to keep the boiler hot. Extrapolating this, I estimate that heating water was burning around a full tank of oil per year – around $900/yr at the $3.50/gal price in Feb 2022.
