- Gravity Warm Air
Gravity warm air systems are common in older homes. Some gravity warm
air furnaces may heat a house relatively well, but it is doubtful that
the temperature control and heat distribution will be as good as with
a forced-circulation system.
- Gravity Steam
One pipe gravity steam heating systems are common in older
homes. The system is similar in appearance to hot water. This is an
extremely simple system, and if properly installed, it will provide
adequate heat, but with no great speed or control. It can be
modernized without basic changes merely by replacing standing
radiators with baseboard heaters. This system can be further modified
into a two-pipe system or a circulating hot water system with greater
heating speed and superior control.
- Radiant
Radiant heat from hot water flowing through coils embedded in
concrete floors or plastered ceilings is less common but may provide
excellent heating. Such systems may become air locked and require an
expert to restore proper operation. Breaks in ceiling coils can
be repaired fairly easily, but repairing breaks in floors is extremely
difficult. If floor breaks are extensive, system replacement is
necessary.
- Electric Panel
Electric panel heating is simple, and offers both good heating
and control. The heating panels should be in good condition unless a
heating element has burned out.
- Oil Burners
All oil burners require periodic inspection and maintenance
(lubrication, adjustment, cleaning) to ensure a safe and
odor-free environment. This inspection should be performed at
least once a year.
- Gas Heating
Gas Burners should be periodically inspected for leaks. They
tend to heat either water or steam boilers, which in turn run either a radiant or gravity steam
heating system.
