Appliance Gas Spillage
Appliance Gas Spillage
当电器将有害气体泄漏到您的家中时，就会发生电器气体泄漏. Causes of 溢出 can be confusing, so we break it down.
我们的家庭能源审计客户经常惊讶地发现，足球外围app哪个靠谱和健康安全是联系在一起的. 如果你有一个自然通风或大气通风的热水器或加热系统，这一点尤其正确.
Most of the time, a naturally drafting system is not energy efficient, 它通过一种称为“燃烧气体泄漏”的过程危及您家庭的健康和安全,” or “溢出".
泄漏的原因可能令人困惑，所以我们将其分解如下.
The bottom line is that 溢出 is problematic, and it can even be dangerous, so you should take the proper steps to stop it in your home. 好消息是，解决泄漏问题不仅能保证你家人的安全，还能让你的设备更节能.
观看下面的视频，了解家电气体泄漏和加热系统的安全问题.
What does “溢出” mean?
炉子、锅炉和热水器燃烧天然气以产生热量. 当你家里的设备燃烧天然气时，它会留下一氧化碳等废物. 在理想的情况下, 废物通过位于电器上方的通风口或烟道离开你的家，并通向外面(通常通过你的烟囱)。. When 100 percent of the waste leaves your home, there is no 溢出. 只有当部分或全部废物无法逃逸到外部时才会发生泄漏.
自然通风或大气通风设备很难100%地清除废气，因为它只依赖于热气体的浮力，让它们沿着通风口向上传播并离开家. 这种设备总是有泄漏的危险，因为气体没有完全与你的生活空间密封, 没有风扇或马达迫使这些气体从烟道排出到外面.
When waste is unable to escape properly, 废气会通过通风口和电器之间的缝隙泄漏回你的生活空间. 这种间隙存在于所有自然通风或大气通风设备上.
Unfortunately, 有许多情况可以防止这种废气逸出并使其泄漏到您的家中. The waste gas contains harmful pollutants like carbon monoxide, 哪一个, if it spills into your home, lowers air quality and can even cause health problems.
CEE强烈建议您采取适当的措施，以阻止任何燃烧气体泄漏在您的家中. Waste 溢出 can get worse as your appliance ages. Don’t risk your health and safety.
Who can help me determine if my natural draft equipment spills?
如果你担心你的自然通风热水器或加热系统可能溢出到你的家, a trained professional can help.
明尼苏达Xcel能源公司和CenterPoint能源公司的客户可以在一年内对他们的设备进行测试 energy audit by a certified energy auditor.
If you have other utility providers, they may offer similar services. 如果没有审计，或者如果你有安全问题，需要立即更换你的设备, 与供暖或管道承包商一起安装密封和电力通风设备.
The solution: Upgrade your appliances
阻止泄漏的最好方法是升级到密封燃烧加热系统和动力排气热水器. With sealed combustion and power venting, the gas waste is completely sealed off from your living space, so there is no way for 溢出 to occur. 有些装置还有电机或风扇，迫使废物通过通风口或烟道排出.
What will it cost to upgrade my water heater and heating system?
一般来说，大多数通风式电热水器的安装费用在1,800美元到2,220美元之间. High-efficiency and sealed combustion furnaces often range from $3,500 to $6,000, and high efficiency boilers cost between $7,000 and $10,000.
如果你住在明尼苏达州，并且有自然通风设备，将废物洒进你的家, CEE的贷款中心可以帮助您为这些替换项目提供资金 nonprofit lending options.
Many utilities also offer 退税 for high-efficiency water heaters, furnaces, and boilers. Always check to see if your project is rebate-eligible.
What causes natural draft equipment to spill?
Spillage is possible with all natural draft equipment. However, under certain conditions, 溢出 is more likely. If your equipment is spilling, 找出导致泄漏的原因，并与训练有素的专业人员一起纠正它. The following conditions often cause 溢出:
- Problems with slope. 热水器的排气口需要有适当的上升，以便重力将废物排出体外. A vent should have a minimum upward slope of 1/4" rise per foot of run. It should never sag or dip. Vents with long horizontal sections should also be avoided. A heating contractor may be able to fix the problem by replacing your vent; however, 最好的选择仍然是升级到动力排气或密封燃烧系统.
- Orphaned vent. 如果你把一个旧炉子升级为一个高效率的炉子，现在它可以从房子的侧面通风, 你可能把你的自然通风热水器的通风口遗弃在烟囱里，它曾经和旧的炉子通风口共用. 它本身可能不再能够从热水器中吸收废物. 如果这就是问题所在，那就计划把你的热水器升级到电源通风的型号.
- Other exhaust equipment. 自然通风的热水器或加热系统完全依靠热气体的浮力来上升并将废物从烟道中移除. 经常, 这无法与其他更强大的排气系统，如厨房抽油烟机竞争, 浴的粉丝, or clothes dryer, 哪一个 have powerful fans and motors that work to remove food smells, 烟雾缭绕的空气, and moisture from your home. When one or more of these fans or motors are running, 它们可以通过把气体拉回烟道，迫使你的热水器溢出到你的家里. If either the furnace or water heater spills in this scenario, it is important to upgrade the equipment. 在更换之前，避免同时运行多个排气设备风扇.
You can read more about these and other conditions on this Structure Tech 博客 Post. 请注意，在这个博客中，他们使用了另一个术语“反向起草”来描述泄漏.
I have natural draft equipment — should I upgrade my appliances?
如果你的能源审核员建议你改用密封燃烧装置，或者通知你当前系统的任何安全问题, you should make the change in the interest of your home’s safety.
也, if you insulate or air seal your home, upgrade to sealed and power-vented models as a part of this work. 虽然隔热似乎与热水器和加热系统无关, it makes your home tighter, 哪一个 increases the likelihood of problems due to 溢出, since gas waste would be trapped inside.
最后, if your natural draft equipment is not spilling, 由于设备老化或故障更换设备时，应升级为密封燃烧版本. CEE recommends replacing water heaters after 10 to 12 years, furnaces after 20 years, and boilers after 25 years.
