What You Need to Know


Superinsulation (See our Deep Energy Retrofit page) allowed us to heat the home last year with this 10k Btu heating system - about one fourth the size of the smallest gas furnace.

Other Benefits:

Cost about 10 times less than a ground source heat pump and is just about as efficient. "Right sizing" means that it does a fantastic job of dehumidifying while it cools the house in the summer.

Maintenance Requirements:

clean the filters every-other month.

Efficiency or Sustainability Improvements:

Everything we could think of!

My Motivation:

A Bright Future!


The best part of my job is helping others replicate the success that I've had making my old house a model of energy efficiency. Please come to the free Tour, or call me at work to set up a consultation.

Experience with Installer:

Nick Anselm was great to work with.
