Oil Heater Systems:

Standard Blower:  A standard blower delivers a specified amount of airflow based on a tap setting.
Variable-Speed Blower:  This is a high efficiency blower that is designed to deliver a varying amount of airflow based on the desired outcome. These blowers increase the effectiveness of humidification, dehumidification, air filtration and balance of airflow.
Boiler Systems:
Indirect Fired Water Heaters:  This style water heater has a longer life expectancy, less standby losses and recovery rates up to 10 times normal coil and water heater rates.
Components include:  Pump Away Process, Isolation of Circulators, Pressure Reducing Valve, Circulators (not Zone Valves), Spiro Vent, Backflow Prevention Valve, Full Flow Valve.
Chimney Liners:
Higher Efficiency Furnaces and Your Chimney:  Most furnaces installed today have Annual Fuel Utilization Efficiency (AFUE) in the 78% to 81% range. Since these furnaces use more of the heat produced by the furnace to warm your home, there is less heat in the exhaust gasses that are vented outside. When not vented properly, these lower temperature exhaust gasses could lead to moisture in your chimney.
Condensation and Chemistry Lead to Corrosion:  If you’ve ever enjoyed a glass of iced tea on a hot summer day, you’ve experienced condensation first hand. Warm moist air comes in contact with the cold surface of the glass and forms water droplets. Something similar could happen in your chimney. Warm moist air hits the cold chimney wall, and water droplets form on the inside of your chimney.  Condensation was not a problem with your older, less efficient furnace, because more of the heat produced escaped up the chimney, carrying moisture with it. But while today’s furnaces are more efficient, they are prone to condensation build-up and that can lead to rust and corrosion.
Why You Need a Chimney Liner: Installing a proper metal chimney liner requires a small cost up front when compared with the costs to repair a corrosion-damaged chimney in the future.
A listed metal chimney liner ensures that your home is up to local and national building codes – an important consideration if you ever decide to sell your home.
A metal liner will protect you and your home against the effects of condensation, including chimney damage, ruined drywall, corrosion in your furnace and backed-up exhaust gasses.
Neerings Plumbing & Heating strongly recommends stainless steel liners over aluminum liners. Stainless steel offers far greater strength.
