Energy

Our push mower is cheap to run, quiet, doesn't smell bad, easy to service and takes up hardly any room in the shed. Oh, and it keeps you fit! What's not to love.

Insulation
So far we think we feel warmer. In a few weeks I will be able to provide conclusive numeric verification based on temperature recordings.
EECA Energy Wise provides funding for insulation.
