Advanced Wood Stove Midstream Program Launched

In coordination with RERC and in partnership with Burlington Electric Department and Vermont Gas Systems, Efficiency Vermont has launched a new midstream program to incentivize advanced wood stove installations. This point of purchase discount is available for Vermonters who purchase and professionally install qualifying cord wood or pellet stoves from a participating retailer. Qualifying installations will receive up to a $1,000 discount.

Stove qualifications:

  • 70% or greater measured efficiency
  • 2.0 grams per hour measured emissions rating

Incentives are available regardless of whether you are replacing an existing stove, live in Vermont Gas territory or in Burlington. However to qualify, these stoves cannot be self installed, and for best results, should be done by a contractor that is a NFI Specialist.

Solar water heating program sunsets

As of October 1, 2018, incentives for solar water heating are no longer being offered. With more cost effectives alternatives coming into the market over the past several years, purchases of Solar Hot Water heaters have slowed significantly. With heat pump water heaters as a viable choice for many customers, Efficiency Vermont will no longer provide rebates for Solar Hot Water. We will, however, continue to monitor the market for innovations in this technology with the potential to produce cost effective solutions for Vermont customers in the future.

Whole building heat pump program launched

What are Whole Building Heat Pumps?

Whole Building Heat Pumps (WBHP) are air source heat pumps that deliver fully distributed space conditioning through a building's ductwork or hydronic (hot water) distribution system. This is contrasted with Cold Climate, Ductless Heat Pumps which heat or cool the room/rooms in which they are installed. In addition to being fully distributed, WBHP are fully integrated with a building's backup or auxiliary heating system, removing any manual swap-over or other system integration issue which may compromise performance. Systems that feed into ductwork though a building are referred to as "Centrally Ducted" while those that feed into hydronic distribution are termed "Air to Water". These systems provide Vermont Customers with the ability to efficiently convert a large portion of their heating to electricity, while maintaining comfort and minimizing complexity of operation.

Eligible Equipment:

  • Air Source Split System or Packaged Heat Pumps
  • ≤65,000 Btu/h Nominal Capacity
  • Centrally Ducted, OR
  • Air to Water

The WBHP program is live as of November 1, though the rebate forms have not yet been finalized. Rebates will be available retroactively to the 1st. Available to residential and commercial customers.

WBHP is offered through prescriptive, end-use customer rebates. Customers (or contractors) will utilize the Residential Heating Systems or Commercial HVAC form to access these rebates. We are currently developing an EEN trade group specific to these technologies. Although it will not be required at program launch, we do anticipate making it a requirement to get access to rebates in the near future.

Centrally Ducted Heat Pumps

These systems, often referred to as "Ducted Unitary," are comprised of an outdoor condenser unit and an indoor air handler, often combined with a fossil-fuel furnace. These systems are also commonly referred to as "hybrid" systems since they utilize 2 difference fuels with pre-programmed swap-over controls. The condenser and air handler must be designed to operate as a system and tested as such by AHRI.

Rebates: $300/ton (nominal capacity)

Performance Requirements:

  • Listed on NEEP Cold Climate Specification
  • HSPF ≥ 10.0, SEER ≥ 15.0
  • COP @5° F > 1.75 (at maximum capacity operation)
  • Compressor must be variable capacity
  • Indoor and outdoor units must be part of an AHRI matched system

Air to Water Heat Pumps

There are 2 main configurations to these systems. "Mono-bloc" systems house all heat pump system components, including refrigerant to water heat exchange in a single box, generally located outdoors. Water must be combined with glycol in these applications and run between the heat pump and the building's hydronic distribution system. The other configuration is termed "Split" because the system is split between an outdoor condenser and an indoor refrigerant to water heat exchanger. These systems rely on a refrigerant line connecting the inside and outside components. No glycol is utilized in these systems since all the water is contained inside the building.

Rebates: $500/ton (nominal capacity)

Performance Requirements:

  • A5W110 – COP 1.7 (At an outdoor ambient temp of 5F, the unit must deliver 110F supply water at a minimum COP of 1.7)
  • Listed on Efficiency Vermont Qualified Products List
