There are as many heating solutions as there are opportunities
for heating. Andrews Mechanical, Inc provides a broad choice
of these solutions to fit your specific need. We offer choices for the new
home owner or to refit the old heating system; an appropriate commercial heating
device, or an economical method for heating your industrial building.

RADIANT: This method seems to be one of the most
popular systems with new home builders and owners lately. We have treated this
area separately on the 'RADIANT' page
of this web site. Have a look! |

FURNACE SYSTEM: This still remains the primary
system of new installations for the majority of contractors which uses natural
gas, electric or other fuel. A furnace works by drawing air inside a heat exchanger,
where it is warmed with a flame of natural gas, propane or fuel oil, or with
heated electric coils. A blower sends the warmed air through the house via
metal ducts; it enters the room through a register or grill in the floor or
wall. Indoor air is circulated continuously through the system, so a furnace
filter is used to contain dust, pollen and other airborne particles. |

ELECTRIC HEAT PUMP: Another home heating option
is an electric heat pump. This unit works by moving existing heat from one
area to another in one of three ways:
* Air-to-air: An condenser absorbs heat from the outdoor air (even the coldest
air contains some heat) and transfers it to an indoor heat exchanger inside
the home. Indoor air is warmed in the heat exchanger and circulated throughout
the home. During the summer, the process is reversed to cool and dehumidify
the home.
* Water-to-air: Instead of extracting heat from outside air, this type of pump
absorbs heat from ground water or surface water, such as a farm pond.
* Ground-to-air: Also known as a geothermal system, this type of heat pump
uses underground loops to absorb heat from the earth. Geothermal systems are
usually installed in newly-built homes, but can also be used in existing home.
One advantage of a heat pump is that it provides both heating and cooling capabilities
in one unit. Electric heat pumps are usually supplemented with a backup system,
such as radiant floor heaters or baseboard units (see below), in case of extended
periods of extreme temperatures. Heat pumps also use filters to reduce airborne
particles and keep the unit clean. |

BOILER SYSTEM: Heating the medium (water, ethelyne
glycol, etc) by various means and then using the same medium to heat the
surrounding environment is an ancient method that is updated by the latest
in technology. Heating boilers by LAARS
or HydroTherm can
give you excellent performance and great efficiency to make your living
space more comfortable. Andrews Mechanical, Inc can supply
you with the system and perform the necessary Combustion Analysis and Water
Condtioning services to ensure the best performance and long life of your
system. |

ELECTRIC RESISTANCE: Electric resistance heating,
usually found in the form of baseboard heaters, was popular during the 1940s
and 1950s, and is often used in multi-family dwelling like apartment houses.
A baseboard unit has an electric heating element encased in metal pipe. Air
warmed by the heating unit rises to the top of the room, and cooler air is
drawn into the bottom of the heater. Each unit has a separate thermostat to
allow for different temperatures in each room. |
