Dan Leonard

Dan Leonard proudly showing off his Maine Master Plumber’s license!

Dan started working ReVision in 2004 at the Liberty branch, when we were still Energyworks. Bringing lots of professional experience in plumbing with him, Dan started as an intern/shop guy and rapidly grew into a project manager. He moved to Portland to begin growing our new branch just a few short years later.  In those years, the Portland branch has grown to several crews and over 30 employees, and Dan is in charge of keeping things in line for our solar thermal and air source heat pump division.

Dan is licensed and knowledgeable in multiple trades including electrical, plumbing, and solid fuels. He is licensed in natural and LP gas, is a Master Plumber and is a certified solar thermal installer. Dan juggles a number of key responsibilities at ReVision, including project scheduling, installations, and customer service.  Dan’s deep knowledge of thermal systems allows him to perform the tricky work of diagnosing, troubleshooting, and servicing solar thermal systems (including those not of our design) which can be notoriously difficult to service, and a capability very few solar installers possess.

Fun fact: Dan received a black belt in karate at 17 while assisting and teaching classes to children and adults. He recently starting learning and performing as a professional wrestler.  No, seriously, check him out on YouTube.

Daniel Leonard's Energy System

Dan Leonard’s home uses a combination of wood stove, natural gas boiler, air source heat pump and solar hot water for heating and domestic hot water supply.

The evacuated tube system provides nearly 100% of his hot water from May to September and roughly 40% the rest of the year.

He primarily heats with wood, supplemented by the heat pump, which is able to extract heat out of ambient air temperatures as low as -10F to heat the home.
