在洪水或飓风带来的风暴潮之后, homeowners are advised to take important safety precautions with regard to their home’s heating and cooling systems. A house or basement exposed to standing water can damage your home’s water heater, 炉, 锅炉, 12bet, 通风, 和热泵系统-把你的家庭置于危险之中.
Flood-damaged heating and cooling equipment and systems should be replaced and not repaired, 根据AHRI. All inspection and replacement work on flooded equipment should be performed by qualified heating and cooling contractors, 而不是房主. 考虑一下新的事物，你就可以把不幸变成机遇, 节能模式将降低你未来的能源账单. Also ask your local utility about available rebates for new energy-efficient gas or propane 炉s.
If you have a central forced-air 炉 in the house you are repairing, 还要注意你的管道系统. A qualified heating contractor will not try to salvage duct insulation that has been in contact with flood water, 但会取代它，因为它无法净化. 你的承包商也会对管道系统进行清洁、干燥和消毒. 要做彻底的工作，就需要拆卸管道系统. These repairs to your ductwork also give your contractor the opportunity seal joints in the ductwork and improve insulation to reduce heat loss.
If there is any question whether flood water has reached a gas appliance, 是否有合格的供暖承包商对机组进行过检查. 天然气炉, space heaters and 锅炉s all have gas valves and controls that are especially vulnerable to water damage from floods and that damage may not be easy to detect. 腐蚀从阀门和控制装置内部开始, 而且损害可能不易察觉, 即使设备的外部是干净干燥的. 至少，这种损坏会导致可靠性问题.
电炉是由电热盘管组成的, 在盘管之间提供空气流通的风扇, 控制装置包括安全继电器. 就像燃气暖风炉一样, 电炉容易腐蚀和损坏, 导致可靠性问题或安全隐患. If there is any question whether flood water has reached an electric 炉, 是否有合格的供暖承包商对机组进行过检查.
使用 extreme caution when there is the potential for propane leaks and get propane equipment checked, repaired and/or replaced by a qualified heating contractor as quickly as possible after a flood. 在任何情况下, your contractor must replace all valves and controls that have been in contact with flood water. Propane systems also require attention to their gas pressure regulator. This regulator contains a small vent hole in its body to sense outside pressure. For effective gas pressure regulation, this hole must always remain unobstructed. During a flood, debris can easily plug the hole, causing dangerous malfunction or corrosion. The regulator should be replaced, as water from floods can carry corrosive chemicals.
在这种供暖系统中, electrically-heated cables are embedded in the plaster or drywall ceiling. The cables warm the ceiling, which in turn warms the room by radiant heat. 如果天花板被洪水弄湿, 石膏板会变弱，甚至开裂, 天花板也需要更换. Although the electrical cables themselves may appear to be undamaged due to their tough, 防水涂料, 电缆上可能有很大的机械应力, and a qualified electrician should be consulted to determine whether the cable is reusable.
Split air conditioning and heat pump systems have power and control wiring between the indoor and outdoor parts of the system, and the piping that moves the refrigerant from inside to outside the home and back.
即使系统长时间与洪水接触, 这个密封的系统可能会保持完整. 然而, if flood water has repositioned either the indoor or outdoor units of a split system by only a small amount, 制冷剂系统有可能发生破坏. The heat pump (or air conditioning system) will then require major repair or full replacement.
注水后制冷剂系统是否完好, 整个系统应进行清洗, 干, 和消毒. You should have a qualified heating and cooling contractor check all electrical and refrigeration connections for both indoor and outdoor units, 包括所有控制电路. The decision to repair or replace should be made by a qualified professional on a case-by-case basis.
你的热水器是否是燃气的, 燃油或电动, 如果它暴露在洪水中, 更换部件. A new water heater is a relatively small investment, and replacing it is fairly easy to do.
在燃气装置中，阀门和控制装置很可能被腐蚀. In an electric unit, the thermostat and controls will likely corrode. 在这两种类型, the insulation surrounding the unit will be contaminated and will be nearly impossible to disinfect. 另外, 绝缘材料需要很长时间才能干燥, 导致油箱从外部被腐蚀.
Even if water heater components have been cleaned and the unit seems to operate properly, 零件将来可能会被腐蚀. Both gas and electric water heaters have a pressure relief valve that can corrode and stick after being exposed to flood water. 因此，一定要更换这个阀门.
一些自然灾害的受害者, government aid may be available to help consumers finance the replacement of flood-damaged HVAC equipment. 12betowners should contact any of the offices of the Federal Emergency Management Agency (FEMA) set up to help flood victims in your area.
