Heat Pump Water Heater Installation: An Eco-Friendly Upgrade for Watertown Homes
Upgrading to a heat pump water heater installation is one of the most impactful steps Watertown residents can take to reduce energy usage and lower utility bills. Unlike conventional systems, these units extract heat from the surrounding air to heat your water, greatly improving water heating efficiency.
How Heat Pump Water Heaters Work
Heat pump water heaters function by absorbing heat from the air and transferring it to the water in your tank. This process uses electricity far more efficiently than traditional resistance heaters.
- They operate like a refrigerator in reverse
- Ideal for installation in basements or utility areas with ambient heat
- Suitable for homes with moderate to high hot water demand
Because Watertown basements are typically insulated but unconditioned, this makes them perfect environments for heat pump water heaters to operate efficiently and quietly.
