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.
