Many Newton residents live in older homes—from Victorians and Colonials to early- and mid-century houses. While these homes have character and charm, they can also present unique challenges when it comes to electrification and energy upgrades.
Heat pump water heaters are among the most efficient ways to heat water in a home, helping reduce energy use and lower household emissions. Traditional models, however, require enough indoor space to draw heat from the surrounding air. In some older homes, finding the right location can be difficult.
Emerging technologies—including split-system and solar-assisted heat pump water heaters—may offer more flexibility. These systems place the heat-pump component outdoors, reducing space constraints inside the home and addressing some of the challenges heat pump water heaters can face in cold climates.
In this short Ask This Old House video, building engineer Ross Trethewey explains emerging split-system and solar-assisted heat pump water heater technologies and how they may offer new options for homeowners looking to electrify older homes.
