Project Description

Location: Marlborough, MA

This home was approximately 10-15 years old, and it contained two hot air gas furnaces and a direct fired, gas water heater. We replaced these items with an indirect water heater, two hydro air units (in place of the gas furnaces) and powered all with a Viessmann Vitodens boiler hidden in these closets that are part of a new finished basement which we are heating with baseboard. We also installed a Mitsubishi mini split AC system for the basement. We installed zone dampers to make the house four zones instead of two, and upgraded the SEER level of the condensers from 9 to 12 SEER for a 20%+ reduction in electrical consumption.
