Two Furnaces one duct system
Comments (7)Of course you can have 2 units tied into 1 duct system. As to your actual question, i'll answer it. You will need to either manually or mechanically block off the unit not being used...Fof instance, install the gas furnace facing the existing heat pump etc, then slide a rigid baffle in front of the heat pump, blocking any pass through air flow when using the gas furnace...lol, simple as moving one baffle incorporated into the supply plenum. 2 separate T stats, separate power supplies, same existing duct system, supply and return. I never did like the way 98% of people ask you more questions than you ask them.....Why, Why, Why.....dunno "Why" they need to know Why, just answer the question OP posted, lol....See MoreOne Heating System or TWO?
Comments (5)I don't know about the builder's economics - sometimes they don't consider all the options. I'll throw out a couple of things. I don't believe that 6 ton units are universally available or at least maybe not 9 years ago. Certainly 7 ton is not available for a reasonable price in residential construction. Cheap requires volume and 6 tons is not a volume item. Zoning right costs money. Really really big money. You can do it on the cheap but you have real issues. So you have a 6 ton unit and only the cottage needs heat. So the blower is blowing 6 tons worth of air flow into 3 small ducts and getting return from a single 20x20 grill. That will make one heck of a racket, there will be increased leakage from high pressures and the blower motor won't like it. A variable speed motor helps and so does a 2 stage system but only to a certain extent. So you can add returns and more ducts but at some point, you have cosmetic issues. I imagine a 225 sq ft cottage with 8 registers and 2 large returns. Even with a staged system, you will have 3 tons going to 225 sq ft, which will short cycle like crazy. So there are plenty of reasons not to do what you are considering. Are they insurmountable? No. But it is certainly not as simple as 3+3=6..... And another thing - 58,000 btu is 5 tons. I would think in FL that cooling load would decide tonnage since it does in NC. Maybe you misunderstood something? Also 8 tons of cooling for that square footage, even in South FL, is a bit of overkill. I have 7 tons for 5400 sq ft and it is a bit overkill....See MoreTwo computer questions
Comments (8)I really prefer Opera - it's the best browser I've ever used. Far more trouble free, far more features, far more customizable You didn't say what you're using but I'm going to guess that you're using Internet Explorer. (sigh) Oh well, your risk. But first, be sure you have a good firewall installed. I like Comodo. Next, install and update about monthly SpywareBlaster. Check for Windows Updates weekly (they usually come out on Tuesday). Requiring you to log in each time suggests an issue with the cookies on your system. Go into the cookie settings an make sure they're being allowed. Especially with using IE, it's important to have a good antivirus running all the time. I like AVG free version. And you should use a malware checker regularly. I like Iobit's Advanced SystemCare since it covers a lot of bases but you should also have a secondary checker too. I like Spybot Search & Destroy and A-squared. Hopefully you got all these programs installed and set up before even going online. If not, do it immediately and run the scans immediately. For the sizing issue, it's an age-old quirk in IE, assuming that's the browser you're using. It sometimes clears itself after a couple days. You can click the maximize button (the middle one in the upper right corder), the click File, Close. If the menu bar doesn't show, press the Alt key to view it, and you can use Alt+F to get the menu. Most of the time you can use the maximize key but sometimes you can only manually drag it out and then use the File Close and live with it that way until it straightens itself out, but most of the time the max button works. It's amazing they haven't done anything about this glitch, er "Feature" since it's been causing people problems for a decade. But Microshaft knows best. At least they think so....See MoreComputer question about startup program
Comments (4)I hope you're able to get your PC cleaned up. If this is an instance of the installation of unwanted items and that's happened before, that might suggest that your security software isn't doing its job. And/or that your internet use habits need to be reviewed a bit. Once you get things back to normal, if you're not using one already, you might consider using a well rated security system. When you use a comprehensive program, utilities like Win Patrol become unnecessary. Attached as information for other readers is a link with trusted ratings of available programs. The not-free versions tend to be more comprehensive. The better rated free ones are capable but many have fewer features. Getting a multi-user license you share within your family or friends can reduce the cost. Also, many internet providers provide top rated products for free to subscribers. Good luck Antivirus software ratings...See More- 6 years ago
