There are three main types of water heaters available in Boston: gas, electric, and tankless. Gas
water heaters are the most common type of water heater in Boston. They are relatively
inexpensive to operate but can be more expensive to install. Electric water heaters are also a
popular option in Boston. They are more energy-efficient than gas water heaters, but they can be
more costly to operate. Tankless water heaters are a newer type of water heater that is becoming
increasingly popular in Boston. They are more efficient than gas or electric water heaters but can
be more expensive to install.
