You wouldn't have gotten any of that here in NJ on a conversion.

It's certainly worth it to run the numbers. A boiler may be $2000 but
it's likely 6000$ installed, forgetting any issues with the structure
(running a new flue, etc.) In the Houston climate, it might not pay.

Bug Out Bags -- levels and layers
by Christopher A. Young
August 15, 2008
Emergencies come in different levels. It is some
times possible to size up a situation. Before, or
during the event. If your car breaks down, and
you're walking home. That's a different severity
than if another nation is invading, and you need
to be out of the cities.
Bug out bags can also be "get home" bags. It is
very possible you're at work, and your chosen
action is to get home to your warm home with a
good stock of supplies.
This article won't tell you what to put in your
bag. Contents are varied, based on your personal
and medical needs. Also time of year, and type
And here are some proposed layers of bags.
When you are on a day hike with your church group,
a fanny pack (also called bum bag) can be worn,
without attracting much attention. This bag straps
around your waist, and allows you to pack some
supplies. With out wearing a full backpack.
Children, when they start walking, can understand
carrying something along. Especially if everyone
in the family is carrying stuff. Kids pack should
be lighter weight than the adult packs. Perhaps
focusing more on food and clothing. Kids grow
rapidly, so check the clothing two or three times
a year, and see if it still fits.
SHORT TERM BUG OUT BAG (ALSO GET-HOME BAG)
If the emergency happens when you are away from
home, a short term bags is needed. Some call this
a 72 hour kit. These bags would be lower profile
and be without obvious weapons. You'd not want
to be wearing a battle rifle on your back to get
home from a traffic jam. That's sure to get you
questioned by the police.
LONG TERM BUG OUT BAG
This is what you would take along if there was a
good chance that you would not be coming back and
things were really nasty. Foriegn invasion, or
maybe EMP burst, and the cities are riot zones.
You'd want much more food, clothing, medical, and
STEP UP PACK
Since many of the same items are included in a
short and long term bag. It makes sense to figure
out what "extra" items are that are needed for
long term. Develop a pack that could be used to
upgrade the short term bag to a long term bag.
In the case of a long term bug out, you would
take along both the short bag, and the upgrade.
Since you're planning for a much longer time
frame, the upgrade may be in a wheelbarrow, or
some kind of wheeled "Mormon Handcart".
If you have one emergency vehicle bag, then much
of the time it's in your "other car" and not with
you. Each vehicle needs a bag, a 72 hour kit
of sorts. With the basics (matches, flashlight,
food, space blankets). Winter beater vehicles
will get extra winter related supplies.
When possible, start your long term bug out by
vehicle. If you have enough early warning, you
may be able to be far enough ahead of the crowds.
You may be able to do 65 MPH down the open road,
which is a lot faster and more comfortable than
walking with a wheel barrow. Rope the wheel
barrow on top of the car, you may need it if you
get into a traffic jam or can't get gasoline.
At least a couple articles have been written, on
the advantage of making an emergency kit for your
home. This is typically packed in a Rubbermaid
tote. Kept near the main door of your home, in
case you need to leave in a hurry. While this
is a good idea, many emergencies happen when you're
already away from home. So, the Rubbermaid
kit should be in addition to your car kits.

Subject: Battery booster pack
Date: Thursday, July 24, 2008 8:17 AM
A useful device, is a battery booster pack. You can find them at Walmart,
or any auto parts store. Just a 12 volt gel cell battery and a couple
and clamps. The one I have, I paid about eight bucks at BJ's Wholesale
I got one about five years ago, and it was totally useful. The battery is
strong enough to jump start a vehicle, when the auto battery is dead. The
inverter on the back provides up to 300 watts of AC 110 volt power for
45 minutes, if the internal battery is fully charged. The booster pack has
an internal charger, just flip open the little door, and stick on the
an extension cord. The booster pack will run a floor or table lamp for
several hours of light. More hours, if you use a power saver compact
fluorescent bulb or fluorescent desk lamp. Much brighter than candles or
camping lantern. And far, far safer.
Has a light on the front. On mine, I pulled the lens off, and pull the bulb
out. It's too easy to bump the light switch and the battery goes dead. At
least, that's what I thought was the problem. Turns out the battery wasn't
holding a charge. This was winter time, so I figured I'd killed the battery
by letting it freeze. Here is an identical unit, with a different brand
Now, the price has gone up a bit. I paid eighty bucks for mine, and now
they are getting one
seventy five. Ouch!
Says retail $250 but they only get $150. Things going up in price, I see.
When mine went dead, I took the cables, clamps, and so on. And the
Wired it all to a garden tractor battery from Walmart. Found out later
own van, that the garden tractor battery isn't strong enough to boost a
vehicle engine. However, it does provide some 12 volt power, and also the
300 watts of AC for a few minutes is useful.
About the time I bought a second one of these. Another eighty bucks. And
the battery went dead. I called the factory and found out they had bought a
load of old batteries. The rep there offered me a replacement battery,
was much cheaper than replacing the unit. Being a repair man, it wasn't all
that hard to pull the box apart, and swap out another battery.
Harbor Freight has booster packs aroud fifty bucks, with a battery and
lighter socket and some cables and clamps. The inverter is only about
bucks at Walmart, so you can get the jump pack and a separte inverter. For
about the same money I paid five years ago. The Walmart $30 inverter plugs
into a lighter socket, so you can move it from car to car, or run it off
battery booster pack.
Of course, you have to charge the unit after each use. Most of these come
with their own wall charger. Take it home and plug it into the 110 volt
power. I rigged a cord with a 12 volt lighter plug on each end. So I can
plug the cord into the vehicle and into the jump pack. Charge while I'm

All of my experience with boilers is with gas fired commercial boilers.
Here in Winnipeg, everyone uses gas fired heating equipment, whether it
be boilers or furnaces. The odd place, usually commercial buildings
like strip malls use electric heat.
I'm surprised to learn that oil fired boilers can be converted into gas
fired units, and vice versa, but it's clear that the boiler would have
to be designed for either fuel right from the start, and I've never seen
that. Perhaps it's more common in more expensive boilers like Viesmann.
But, if you go onto a more common boiler manufacturer's web site, like
Weil McLain, they classify their boilers as gas burning and oil burning,
and so far as I've seen, they don't have a catagory for either/or.
Anyhow, now the OP is aware of the possibility and can check to see if
it's a feasible option in his/her case.
Never heard of a vice versa. Wouldn't think there would be a demand.
If I remember right there were gas conversions for coal furnaces. I know
there were gas conversions for oil furnaces. I would think there are
(were?) gas conversions for oil boilers. (Maybe not now with tighter
Weil McLain is the largest manufacturer of cast iron boilers in the USA,
and I expect the largest manufacturer in all of North America.
Here is Weil McLain's "Products" web page that shows all of the
different types of boilers currently available from Weil McLain.
'Residential Boilers, Commercial Boilers | Weil-McLain'
Note the "2" at the top of the product selection indicating that the
first page only shows the first 12 different kinds of boilers. Weil
McLain offers 9 different kinds of residential gas fired boilers, 4
different kinds of oil fired residential boilers and 7 different kinds
of commercial boilers.
On the second page it calls three of their commercial boilers "gas oil"
boilers, which to me means that they can be set up to fire on either
kind of fuel; and could undoubtedly be switched from one to the other
relatively quickly and easily. I could see a demand for that feature in
places like Alaska where gas may be temporarily interrupted by an
earthquake that severs the gas lines. Places like hospitals and
government offices could have their own oil storage tanks and switch
over to burning oil until the gas service is restored.
What I don't see, however, are residential boilers that can burn either
kind of fuel or a conversion kit to allow a residential boiler firing
one kind of fuel to burn another. What I do see, however, is that Weil
McLain's GV90+ gas fired residential boiler can be easily converted to
propane, which would be of similar advantage to houses in Alaska or
California or British Columbia where earthquakes are more common; or in
urban areas where the gas utility isn't reliable.
'GV90+ Gas Boiler | Weil-McLain | Product Detail'
Anyhow, it's possible that boilers made 20 years ago, and those that
sold well in some parts of the continent were different than those
available today. But, from what little snooping I've done on Weil
McLain's web site I'm coming to the conclusion that being able to switch
a boiler that's meant to fire gas to one that burns oil, or vice versa,
isn't very common. If the boiler was designed to fire either fuel, you
have that option, but if it wasn't designed for that, then I'm expecting
that option isn't available to you.
But, I'm old enough to acknowledge that I don't know everything like I
did when I was 15, so I might be dead wrong on this one too.
All sorts of combinations exist.
I've been associated with boilers in one way or another since my first
job in 1963 where we build heating and AC products. Last place I worked
we had dual fired units. We'd run gas most of the time, but when it got
really cold, the gas company would call and give us two hours to switch
over to oil. We got a special low rate for that and we'd only have to
go to oil a few days a year. We burned about 250 gallons of oil a day
so the price differential was considerable.
At another place, we burned #6 oil. On a Monday, you's start up with #2
until the pre-heater with steam probe warmed the #6 to flow.
The building we have where I work now has just about anything you can
imagine. Two fire tube gas high pressure steam boilers for process, a
gas cast iron low pressure steam for heating, 5 gas unit heaters, 2
steam unit heaters, 2 oil furnaces. 2 gas high efficiency water boilers,
3 gas fired rooftop heating units, fin and tube cooling tower, water
cooling tower, water recirculating system (tank, sump, 5 pumps) for
process cooling and even some electric baseboard. Getting ready for
winter keeps my maintenance guy busy for a couple of hours.
You can. There are gas "conversion burners" made to replace oil
The gas is "sprayed" into the combustion chamber with air, just like
the oil burner. Gas has the advantage that it's cleaner and is
already a gas so doesn't have to be atomized. It works really well.
You can. It's a simple swap of the burner. They aren't all that
cheap but it's a trivial job for anyone who has serviced oil burners.
Somewhat true. Many areas that didn't have gas service fifty years
ago, now do. It really is worthwhile to convert, given a chance.
Obviously, if there is no gas available (or propane is too expensive)
it can't be done (or isn't worthwhile).
Not so much. A 20Y0 firebox likely won't last that 80 years. If major
surgery like that is needed, scrap the whole thing and get an updated
That's a good point. Heating-degree-days make all the difference.
If natural gas isn't available in Houston, I'd be looking at a
mini-split (heat pump).
Good grief. These things aren't rockets. If it doesn't work, swap
There's no way to know without running the numbers. I'd certainly do
everything possible to get rid of an oil burner!
You bring up a good point. It's quite likely that he already has AC,
so switching that to a heat pump shouldn't be a big deal. Gas is
almost certainly a better choice but a heat pump shouldn't be a
terrible choice for Houston.
Another consideration that hasn't been mentioned so far is that by
switching to a high efficiency gas (or oil) boiler, you also acquire a
They call them "condensing boilers" because they recover so much heat
from the burning fuel that the water vapour in the flue condenses to
Now, anyone that's familiar with drinking carbonated soft drinks knows
that CO2 dissolves in water, and that's often what gives carbonated
soft drinks their "bite". Well, in the case of the condensate that
comes off of high efficiency condensing boilers, that condensate is
actually very acidic, and just putting it into your house's main drain
line isn't healthy for that drain line.
In my case, when I put my two high efficiency condensing boilers into
service, I immediately set about making a pH neutralizing filter out of
limestone. Basically, the condensate would pass through a 5 foot long 2
inch diameter PVC pipe containing limestone before it would end up in my
The limestone we have here near Tyndal, Manitoba is about 95% calcium
carbonate. It's basically the calcium carbonate shells of sea creatures
that lived millions of years ago and compacted into a continuous rock by
the weight of Lake Aggasiz, which was a lake that covered most of
southern Manitoba millions of years ago. But, even at 95 percent
calcium carbonate, I was still finding that I had to clean my limestone
every coupla weeks or so. The condensate would dissolve the calcium
carbonate, but leave behind the 5 percent that didn't dissolve as a
"fuzzy" kinda residue on the limestone rocks. That fuzzy residue would
keep water stagnant within the thin layer of fuzz just like insulation
keeps air stagnant, and that would severely reduce the effectiveness of
the filter. I had to empty the limestone rocks out every couple of
weeks and basically rub them against each other so that they cleaned
that fuzz off each other, thereby restoring the effectiveness of the
filter. Now, I'm using a product called NM-20 from Axiom Industries in
Saskatoon, Saskatchewan that's almost 100 percent soluble in the
condensate, and so I only clean my pH filter once every few months now;
more often in winter because of the additional condensate produced.
But, if the OP is a busy professional with kids that need to be
chauffeured to soccer and judo and ballet and every other kind of
activity kids take an interest in, it might not be the smartest thing to
opt for a high efficiency condensing boiler because that's going to give
him/her one more chore that needs to be done periodically. They might
prefer to simply have a less efficient boiler and let the water vapour
go up the chimney than be saddles with additional work cleaning their
condensate neutralizing bed regularily.
I know when I was still using limestone in my neutralizing bed I was
wondering how much longer I could keep up that practice of cleaning the
limestone every 2 or 3 weeks, and the idea of keeping it up for years
was a depressing one.
Well, many soft drinks use phosphoric or citric acid to give them a
"bite". Carbonic acid isn't all that "acidic".
What's the problem with mildly acidic water in the sump pit? There's
plenty of water in the ground to dilute it. I can understand some
concern about cast iron plumbing (though it will he highly diluted)

and that's where my condensate goes. Condensate isn't going to
do anything to it. If you have cast iron or copper, then I guess
it's another story, especially if the condensate is the only
thing that's in that waste line. If it's a cast iron main sewer
line, with all the other water that typically goes down it,
I would think it would probably take a very long time for the
condensate to have an effect on it. All kinds of slightly acidic
or slightly base liquids that are slightly corrosive go down
sewers all the time.
Around here they go into the sump pit with no neutralizer. I
haven't seen or heard of any bad things happening.
That must be fun. I can't imagine many people doing it.
Only if they have special circumstances that require it or
local code requires it.
I've seen dozens of condensing furnaces installed here in NJ,
not one has a neutralizer.
If most people were doing that cleaining/maintenance, you'd be
hearing a lot of bitching.
Did you seek therapy? Maybe some Prozac would help.
Do you have a PH number? I don't see a problem with either clay or
plastic drains. If it goes into a washtub or similar drain, it is so
diluted I doubt it would bother anything. The cast iron, maybe, but
that may even be coated with a protective coat of scum.
Condensing boilers have been around for a long time and I've never
heard of anyone actually having a drain related problem from them.
I do know that with steam heat, the condensate pipe will rust out
before the steam feed pipe. But we are talking gallons of condensate
per hour over years.
Seems rather extreme and a lot of work. How about dumping in some
baking soda once in a while and eliminate the other filters?
I used to take samples of my condensate down to my plumbing wholesaler
and they would measure the pH as a free service. I've had condensate of
pH 3.1 coming out of my boilers, which is about the same as grapefruit
juice. That's when I discovered the problem with using 95 percent
limestone. The remaining 5 percent that didn't dissolve caused a
stagnant layer of water around each limestone rock, preventing the
limestone from neutralizing the condensate.

If you mean using baking soda in my neutralizing bed, baking soda is far
too fine a powder to be used in the neutralizing bed. You have to
remember that it's only a pressure difference of about 4 inches of water
that drives the condensate through the neutralizing bed, and a fine
powder like baking soda simply would't be permeable enough to allow
water to flow through it with that small a pressure driving it. And, of
course, CO2 bubbles are produced as the condensate dissolves the
carbonate, and those bubbles have to be able to pass through the
neutralizing bed as well, or else everything gets clogged up.
What you need for a condensate neutralizing media are stones somewhere
between the size of peas and grapes that will allow condensate to flow
through them easily but still provide enough surface area for all of the
condensate to be neutralized.
I've read all the responses up to this date.
Another expense to consider is that when converting from oil to any
other fuel or electricity there is the expense of the removal of the oil
in the tank and either filling the now empty buried tank with an
appropriate filler (I would use concrete to prevent the tank caving in)
or the removal of the above ground tank.

If it's underground, it can be leaking and you'd never

any experiences they've had with similar tanks. The

Filling the tank with concrete wouldn't be my first choice.
It creates another potential problem, ie that if you ever
need to excavate that area for something, eg running some
pipe, septic system, house addition, etc you now have a
huge concrete mass. Sand or gravel sounds like a much
better and cheaper alternative, which is what I've seen
used here in NJ.
