Carbon Dioxide is heavier than air (as is propane). Because CO has nearly the same specific gravity as air, the alarms can be located either low (for plug-in units) or high on ceilings or 6" below ceiling on walls (avoid corners where air is dead). Do NOT install one in a garage as it will constantly alarm from the car exhaust.
The two best carbon monoxide monitors, the CO Experts monitor and the NSI 3000 from the National Comfort Institute, don’t have the approval from Underwriters Laboratories (UL) that so many manufacturers crave. There’s a good reason for that. The CO Experts and NSI 3000 monitors are low-level monitors that tell you what’s going on with the ...
A detector should not be placed within fifteen feet of heating or cooking appliances or in or near very humid areas such as bathrooms." AlanB4 | Oct 23, 2015 12:06am | #2 I've read that monoxide detectors use sensors that get fouled up with VOCs over time (one of the reasons they should be replaced every 10 years), and fireplaces generate quite ...
Propane has 3.3 times the GWP of CO2, while methane (aka natural gas) has about 25 times the GWP of CO2. In all cases, GWP is not the best measurement to use, because it is based on a 100-year scale. We have a decade, maybe two at most, to get carbon emissions under control, not 100 years. On shorter time scales, greenhouse gas impact is magnified.
Run two ducts N-S across the buidling. Fit one duct with a non-return damper at each end which allows air to exhaust and similar dampers in the other duct allowing air in from outside. Irrespective of which way the wind is blowing, air will always tend to be sucked out of the exhaust duct and blown into the inlet duct.
Carbon monoxide and water vapor. Nitrogen dioxide, carbon dioxide, and other combustion products can certainly create problems for indoor air quality, but I’m going to focus on the big two here, carbon monoxide (CO) and water vapor. Let’s start with CO. As you see below, carbon monoxide has a carbon atom and an oxygen atom.
In homes with a single central return-air grille, return air often struggles to find its way back to the furnace. The result: room-to-room pressure imbalances that lead to uneven room temperatures, comfort complaints, higher energy costs, and even moisture problems in walls and ceilings. When a furnace comes on, heated air is pushed through ...
Open- or closed-cell spray foam insulation is a great way to get air sealing and insulation in a single step, but the health implications are fuzzy. Spray foam is a great air seal and insulator, but the jury is still out on the health effects of possible fumes. Spray-foam insulation has become a weapon of choice for many builders and homeowners ...
Martin Holladay #1. Chris, First of all, you don't have to put your furnace and water heater in your attic. In fact, there are several good arguments for putting these appliances somewhere else -- the attic is just about the worst place in your house to put these appliances. Better locations for these appliances include a basement, a crawl ...
The manufacturer says the new Thermax qualifies as a low-VOC, HFC-free, and zero-ODP (no chlorine content) material, helping reduce building energy use and the carbon footprint. It’s available in standard 4×8 through 4×12 sheets in thickness of 1/2 to 3 in. with a thermal value of R-7.3 per in. Rockwool Comfortboard 80 is a rigid stone wool ...
