Get Ready For HeatSmart


Great news! The Towns of Carlisle, Concord and Lincoln have been chosen by MassCEC to promote clean heating and cooling technologies in 2018 (press release). The technologies include super-efficient Air-Source and Ground-Source Heat Pumps, and renewable wood pellet heating systems, which can greatly reduce greenhouse gas emissions and save money over time. Participating residents and small businesses can take advantage of significant rebates and installer discounts to make these systems affordable.

The program will take place between February and July 2018. In order to participate, homes will be required to have had a recent energy audit. Free energy audits can be arranged through one of these links:

Sign up for your audit right away!Following the energy audit, you can take advantage of generous rebates for weatherization of your home, saving considerable $$ and reducing the capacity needed for a new heating system.

The program website will be available soon here with program details. To find out more about HeatSmart, receive HeatSmart notifications, or to get involved as a volunteer, please contact the coach from your town:

Take advantage of the new CMLP rebate for Air-Source Heat Pumps

Great news! The Concord Municipal Light Plant has recently introduced a rebate specifically for Air-Source Heat Pumps designed for super-efficient heating and cooling in cold climates. The rebate of $625 per ton (12,000 BTU/hr) of capacity will take a substantial chunk out of the cost for new installations. Eligible equipment is rated for heating down to outdoor temperatures of 5 deg F or below with high seasonal efficiency (HSPF>=10). For complete details, visit this page.  Feel free to contact Cooler Concord for advice on heat pumps, or to share your experience.


Attic insulation

We just got rid of our ineffective, old attic insulation and installed closed cell blown-in foam in the attic rafters. The difference so far is remarkable. Attic temps on sunny days are at least 20 to 30+ degrees cooler which has enabled us to forego using air conditioning on multiple days.The extra cost of closed cell foam is significant over fiberglass, however the higher R value and ability to seal in the attic space made it worthwhile in my opinion.

The work was done by Green Stamp of Waltham. They coordinated the insulating with our general contractor, North River Builders of Concord. Quite pleased with both companies.

Can’t wait to see the reported additional benefit of ice dam prevention in the winter.

Our new heat pump

Last week we had a Carrier Infinity heat pump installed in our home, which replaced the 20 year old central A/C unit.  We got several options quoted to us by several installers, and chose the Carrier since it was the highest efficiency, with an HSPF of 13.  It was installed by Muirfield Mechanical, who did a nice job.  The compressor (shown in the picture) fit where the A/C unit was, though it is taller but pretty quiet when it is running.  The indoor unit also fit in the closet where the old air handler was, so the installation was straightforward.  The controller which replaced the thermostat connects to wi-fi so we can control the system remotely, and it can switch between the heat pump and the natural gas boiler when the temperature gets low.  For testing we set it to “heat pump only” and it heated the house just fine when it got to be as low as 17F the other night, which we were happy to see.  We hope the heat pump will lower our gas use by 60-80% in a typical winter, time will tell.
