Summit Natural Gas Residential Customer Rebates

Upgrade to Summit Natural Gas of Maine, an efficient heating system, and a weatherized home and you could qualify for up to $3,560 in rebates and $25,000 in financing. Think of it as home comfort paid for by energy savings.

Benefits of Natural Gas

Natural gas is the nation’s primary source of heat for many reasons:

Some modern gas boilers are small enough to be wall-mounted.
  1. Low rates – Natural gas is currently one of the lowest-cost sources of heat.
  2. More efficient – Natural gas boilers and furnaces can be more efficient than oil systems because they can adjust their heat output to match demand (“modulating”) rather than having to cycle on/off and they can extract more heat from their exhaust (“condensing”).
  3. Convenient – Because natural gas is piped directly into homes, there’s no need to schedule deliveries or store fuel on-site.
  4. Better for the environment – Compared to oil or coal, natural gas has lower greenhouse gas emissions.

Benefits of Weatherization

  1. Reduce heating bills.
  2. Reduce/eliminate cooling bills.
  3. Increase comfort in both summer and winter.
  4. Eliminate ice dams on roofs.
  5. Avoid frozen pipes.
