@ December 8, 2013 3:17 PM in Coal Still Feasible?Steam or Hot Water?
If hot water check out alternateheatingsystems.com.
A goup of fellows in my area (central New York) each purchased one of these
and are very satisfied with them. Substantial fuel savings over oil. They get
together and buy a truck load of coal out of Pennsylvania each year. Comes
bagged on pallets, the truck is specially built with rollers for unloading. I
helped them with system design.
@ December 4, 2013 8:57 AM in Putting system together - pump selection help"Siggy's Hydronic Design Studio II - Hydronic Circuit Simulator section is a very useful tool for estimating head loss & for pump selection. I've used it for some time now & find it to be quite accurate. I believe Hot Rod & Mark E are familiar with it. I believe there is a free trial use of it on his web site - hydronicpros.com
@ March 2, 2013 11:26 AM in Should I add a vent damper?Hap,
This is probably a stupid question because you sound very knowledge,
but did you follow the manufacturer's wiring instructions exactly? Or perhaps
the damper has a harness that simply plugged into your control circuit.
Then did you test the fail safe operation of the damper? Sorry if I affended
you, but you can't be to safe.
@ February 25, 2013 5:15 PM in favorite zone valve?Over the years (52) we have used just about every zone valve out there -
Flair, Dole/B&G, White Rodgers, Hwell, Erie & lately I've been impressed with
Caleffi. Sold litterly 1000's of Hwell. We found the biggest problem was the
end switches didn't hold up. The best thing in my opinion to happen to zone
valves in recent years was the introduction of the zone valve zoning panels
Taco & Argo to name a couple. These allow you to not use the end switches
on the valves if you choose not to. Since using these our zone valves last much

If my memory serves me correctly I believe the minium return air temperature
furnace manufacturers like to see is 60* coming back to their units (Carrier
& Lennox for sure) for any sustained time. This could cause condensation

@ February 17, 2013 2:46 PM in Any one know where to buy parts for old boilers?Tim,
Wasn't there a resistor you could mount under the auto pilot to bypass a troublesome pressure switch internally in the valve? Wonder if thats whats going on.
@ February 17, 2013 2:35 PM in National ConvectorsThere's a book Dan's got out - EDR - Every Darn Radiator. The're in there. How old is the house?
@ February 17, 2013 2:29 PM in Choice- Lochinvar WBN051 or Cadet CDN040?Have you guys taken a look at Siggy's Hydronic Design Studio-2. It uses all your formula's and will give you an answer in 2 minutes.
@ February 15, 2013 5:13 PM in Sizing issue for replacement steam boiler for single pipe steam system;THANK YOU SWEI! JOHN PUGHE
@ February 15, 2013 4:51 PM in Sizing issue for replacement steam boiler for single pipe steam system;JNY is correct, there are also other things to consider, are the pipes insulated or are they uninsulated to name one. Dan wrote a wonderful article some time ago with reguard to properly sizing a steam boiler replacement. I wish I was good enough at this computer stuff to know how to post it for you. Perhaps Dan will chime in on this
@ February 14, 2013 3:35 PM in What business lessons did you learn from the Great Recession?Hey Dan,
You must be doing "RESEARCH" for a future article.
@ February 10, 2013 2:13 PM in Utica Boiler ignition problemRight on Toddy!! Oh for the good old days. I'll stop down & visit you one of these days. I think I still have an extra circuit breaker I'll give you.
P.S. I also think its great your willing to help this gentleman on a weekend. I'll let Scott know how dedicated you are, maybe they'll put something in the old envelope for you.
@ February 10, 2013 1:40 PM in Utica Boiler ignition problemI used to carry a little plastic 3 amp - 5 amp circuit breaker (got them through
Carrier, your would find them in their low voltage circuitry on their rooftop units)
They were perfect for a situations like this, saves going through a bunch of fuses
until you find the problem.
Todd, go out on that flat roof above the lunch room you'll find one in that rooftop
if it's still there. Just kidding LOL.
@ February 7, 2013 3:47 PM in Head Loss Cumulative?How about TRV's on your heat emitters with a homerun system using
the Alpha circ. Much simplier wiring. You could get a manifold with flow meters to monitor whats
going on. I'll bet 3/8" might work on some of your runs. I would also suggest
Pex-Al-Pex over Pex - It expands much less than pex & I think it is easier to
@ February 7, 2013 3:33 PM in heat load calculation-HELPSorry Charlie,
I should have described it better. I was referring to a wall - 2x4 or 2x6's on
16" or 24" centers or ceiling rafters. The program takes into account the
different "R" values for the "stud"area and the cavity.
@ February 7, 2013 10:46 AM in Cold showers?Sorry for the spelling Gordan, I blew that one.
@ February 7, 2013 10:44 AM in Cold showers?Good point Gordon - if memory serves me I believe it's 27 Gallons.
@ February 7, 2013 9:49 AM in Cold showers?hEY Robg
If you go to Ergomax.com they have piping diagrams there showing proper
piping. We put in several of these and always included a mixing valve.
Take a look & see what you think.
@ February 7, 2013 9:37 AM in heat load calculation-HELPIf you are looking for a heat loss method try going to hydronicpros.com -
thats John Siegenthalers web site. Go to the download section. There is a free download there called Heat Load Pro Trial Version. I've found it to be a very
accurate program for calculating heat loss. It even accounts for the effect of studding. If you like it you can purchase the full program.
@ February 3, 2013 2:13 PM in Baseboard Calculation QuestionTry Slant Fins web site, look under commercial baseboard for a model
that is close to your model's demensions, they show several. That would probably
be close enough.
@ February 3, 2013 10:32 AM in Cold showers?That Ergomax indirect has boiler water in the tank and a coil for the domestic
hot water within the tank surronded by boiler water. The proper hook up for
one of these would be to have a thermostatic mixing valve installed in the
domestic piping along with a thermometer to monitor the exiting water temp.
The aquastat in the tank should then be set to 160-180 degrees. then you dial in
the exiting water temp with the thermostatic mixing valve.
You could first strap a thermometer on the hot water supply pipe exiting the tank,
open some faucets and see how it responds. I've also seen these internal coils
get dirty which cuts down there capacity.
