remote exhaust for generator

It has taken 2 days but I managed to get it finished . Through wall exhaust Heat sleeve and muffler stub adapter . Our generator and hook up is in our garage . So when we run it we have to have a fan blowing out in the window and the garage door open because of the exhaust . Having it in there means it is out of the weather ect. but the exhaust is an issue . Once installed the new flexible stainless steel exhaust hose will clamp on to the adapter at the muffler and then snake its way up and out through heat sleeve to outside reducing noise and eliminating fumes in the garage . I have already converted it to 12v electric start form left over riding mower parts making it easier to start . So now we will be able to start up and switch over the manual disconnects for all the essentials this fall and winter , which I feel are going to messy and many power outages this year.
Our system is very simple form of manual disconnect . For every important appliance (2 fridges ,2 freezers, gas furnace , well pump, hall light smoke / co detectors ) there is 2 receptacles , 1 house circuit and 1 generator circuit and all have cords even the furnace and the well pump have machinery 12 gauge flex cable with 15 amp cord ends . When the power goes out we just fire up the portable 5500 watt genny and then go about switching the plugs from house to genny circuit. It is a little more work but is completely legal and at a fraction of the cost .
Hope this helps others looking for a cost effective way to provide emergency power to your house .

Thanks Dave, it's something we need and I should implement at some point.

Next time you are over I will show you how I did it . Once you see it it will be a piece of cake for you . I would up load pics but my phone has lost the password and I can't remember what it is . The lap top know what it is but won't let me see it . Some how I need to get all my pass words into a book so I can forget where that is . FACE PALM.

So the manual disconnect is as simple as this at each appliance .
The first pic is the second fridge hook up and next is the furnace . All the others are the same . Although it takes a few minutes with a flash light it saved me thousands of dollars and alows the genny to take on one load at a time instead of a big spike . I hope to be putting in the
exhaust pass through sleeve today if my bud has time to help with the hole and will take pictures . Feeling better but still limited on what i am aloud to do physically .

Nice, simple, cost effective set up Dave.

When you loose power often and for long periods you have to do something.
It doesn't happen often for me, but I have a setup to run off of
generator.
Glad to hear your doing better, sitting around is not easy when you're use to being active.

Great simple solution, I like it! I might have a problem setting something like this up at our place, we have baseboard heaters at 3000 watts a piece and no generator yet but considering getting the 9000W champion generator from Costco. Not sure yet how I'd hook up the heating.

A
generator large enough to run elect heat is not cost effective . Your best bet is to put in a back up propane heater and have fridge , freezer, well pump ect. . Wood stove work but are hard to insure and need babysitting .

Indeed, one of those many things that need to be redone here. We've been slowly improving the house, but still a lot to do yet.

I'm with Dave, running electric heat would be costly.
I'm from the"BE PREPARED" camp. Not a boy scout, not a way out there "prepper", but a how am I going to take care of my family when something happens kinda guy. 14 years as Fire Chief kinda reinforced that thinking.
We don't have outages often, but we've done a couple of multiple days in recent years after wind storms and a tornado. Went 7days in 2001.
They are nice, but I can't justify needing or the cost of a standby generator.
Summer time keeping the fridge and freezer going is the main concern. During winter heat is the concern, keeping you and your home from freezing gets important.
We have wood as our secondary heat after natural gas. It would be enough to stay comfortable for an extended outage if we closed off some of the house.
I am fortunate to have 8000, 10000, 11000 watt for my business that I can grab when needed. The down side to these is they can go through some serious gas. We picked up a smaller 6000 watt new in the box, cheap at an estate sale a couple of years ago, haven't needed it to see how it works, but should use less gas.
Some random thoughts,
*How often do you loose power
How long is it normally off for
*Calculate how many watts you actually need
Tell the kids they don't need everything on
*Don't buy way bigger than you need
*How much gas are you going to keep around
*Now you have another engine to maintain
Will it start when you need it to
*Be safe about it, CO cautions, grounding,
transfer switch/separate circuits

Around here it comes in waves then long periods with no outages . Just never know . I consider myself p repairer not a prepper as well . w are on natural gas as well , Everything is on gas so things like the furnace just need 110 v with a max amps of 8 on start up to heat the house . 2 freezers and 1 fridge are in the unfinished basement where it is generally cooler to start. When the power goes out electronics go away and candles and board games come out . our grandson Jacob actually gets a kick out of it and has turn the lights back off when the power comes back on if the game is not done .

We only lost power once, when a large tree was brought down by a storm right over our power lines. Lucky us didn't fall on the house. Our house is really tiny and has been built as a cheap cottage. I have doubled the wall insulation and tripled the roof insulation, replaced some windows. We don't have natural gas here, yet a couple of streets over there is. The gas company says not enough customers on this side to extend.

I considered propane tank rental but then I'd need to change quite a lot here to install a propane furnace (no room in the crawl space

). We really want to build an addition to the house, but guess what, the banks don't give you a mortgage for that, you need to build it with your or borrowed money and then you can remortgage. And the current material prices are crazy still. They never lose, banks and insurance companies

. So we're ok with electrical heating for now, and it's not that expensive for our tiny house, especially after I improved the insulation.
Back to how to switch power from
generator to hydro. I am wondering why not supply power from the 240V/30A
generator outlet directly to a 30A outlet like the dryer outlet, after switching hydro off at the main panel. We have a 100A main switch on the panel. Turning that off disconnects you from hydro power, and basically should isolate the house completely even when the power comes on. The power from the dryer outlet that comes from the
generator is spread across the house then over the original cabling. Of course, you wouldn't want everything to be on, just the important devices, and you can do that from the electrical panel by turning off fuses. Am I missing something here?

@Eugen your not missing anything, back feeding like this will work. As long as you always remember to turn off the main and don't exceed the 30 amps the circuit is wired for. That said, most places codes require a transfer switch. This makes it fool proof that you don't send power back into the grid.

Yes, the code

, I know. But perhaps it's ok if you exceed the 30A because the breaker on that circuit should trip. Of course, this is just a thought experiment, I would not actually do it like this, I'd install a transfer switch.

It is more than just the code . If you do not have complete separation though an approved transfer switch or manual disconnect system like I have you could face a fine of I beleave it is $100,000 or more and if anyone is injured or worse from back feeding to the system while they are repairing it Criminal charges you will face . In Canada they do not take this lightly because hydro workers have died . Come look at my system take some pictures .
A small propane "externally vented fireplace" run of a couple of 20lb tanks would keep you and your house from freezing during the odd power outage and is more cost effective .Good used ones can be had as more people convert to Natural gas. The trick is to keep a couple of full tanks on hand at all time and refill immediately after use ,no need to rent big tank.

Exhaust and a bigg portion of the noise now exits the building . CO detector did not go off while on test run
pony panel with 15 amp breakers that plug into the genny.

As usual Dave, from almost nothing, you put together a full solution! Very neat work there and I will copy your doing when the time comes and we get a
generator! Thank you for sharing your work with us!
Yes, I've been thinking about a propane based heating system.

Depending on your building design you may consider propane fired boiler / hot water radiator system which looks and works in each room similar to electric rads and can be converted to natural gas easily if then come available. This is a great option if forced air is not a viable option due to design .
Anything that runns on a fuel need far less power to run the system , There are more options than you can shake stick at in a month of Sundays .
The question is what will work the best for you in your budget.

I can buy an interlock kit for my Eaton circuit breaker panel. Its basically a $70 piece of sheet metal that forces you to turn off the main breaker in order to enable the
generator breaker which has to be located in the top right panel slots. Never got around to wiring in my Northstar 10000 PPG
generator. I ended up getting it sold recently just before Hurricane Henri. At 320lbs it bothered my back to move it even on 4 wheels and it was just too damn loud.
I've still got a
generator, its a Westinghouse iGEN4500 inverter
generator. Very nice quiet fuel efficient
generator. The only downside is its 120V only. I can't run my well pump with it.
Your typical
generator runs continuously at 3600rpms to generate 60Hz electricity (3600RPM / 60 = 60Hz). An inverter
generator has the ability to vary the engine throttle depending on the load. An inverter
generator uses an alternator whose output is then fed into an inverter to generate the proper voltage and frequency independent of engine rpm.
Here are a couple of reviews if anyone is interested:
