Natural Gas Heat Recovery Ventilators

Save energy costs and keep your home more comfortable year round.

All homes require ventilation to keep the air inside fresh and prevent it from becoming stale. In typical ventilation systems, that means that warm air is exhausted out of the home and the energy used to heat that air is wasted. With a heat recovery ventilation system, up to 70 percent of the heat from exhausted air is retained for use in the home, allowing for lower energy usage.

The Sponsors Mass Save® offer natural gas customers rebates of up to $500 on heat recovery ventilators, which can keep your home comfortable – and your energy bill low.
