Cooling Question
@ February 10, 2012 8:05 AM in Cooling Question
I am currentlylooking at a job that has an extremely large furnace 120,000 btu's (two times the heat
load) but a properly sized single stage 4 ton a/c unit.
The homeowners would like to zone the house from top to bottom! The first floor load is basically two thirds the entire load.
I do not see how this would be advantages to them in anyway. Especially
with bypass dampering the single stage 4 ton a/c system will short cycle
and not dehumidify the home properly.
Just looking for others input for or against my thoughts. Any information would be greatly appreciated

Finally completed my boiler!

After getting the first gas bill in my new home I decided to shift priorities and install my boiler!!!!!Help Tim!!!!

There has been much debate in our shop regarding this topic lately!We all know if you need "more" gas because of multiply appliances in a location you need more VOLUME!
The debate is where do you need the volume from! Some guys think that
you need the largest pipe to carry the gas as soon as it comes through
the wall and into the house!
Others think that you can add the "volume" section close to the
appliances and that will be fine. Argument being that a lot of the low
pressure gas lines in our area come into the homes 3/4" anyway so why
does it mater where we add the volume?
Any well knowledge gas pipe sizing guys out there?

But the argument is still that the top and bottom of the meter are supplied with 3/4".When and how does the volume come into play?

@ May 24, 2010 5:24 PM in Timber Framed Home
We just got brought onto a project that is pretty far along on the building process. It is a Timber Framed Barn that has been converted into a residence. All the interior framing is completed but the previous builder didn't let any of the other trades in. The house has no conditioning or electric yet?????I wanted to know if any of you guys have experience with Timber Framed structures and what types of systems have you used? It is such an eye pleasing structure that we don't want to hack it up with ugly duct-work or copper baseboard. We are entertaining the idea of radiant but cost and the available floor space is a factor....
Thanks,
Jamie

Does anyone make heatload applications for Macs????Zone Valves
@ November 26, 2009 4:55 AM in Zone Valves
What have you guys found to be the most energy efficient zone valve on the market?We are always trying to make are systems more and more efficient and with the introduction of the Grundfus Alpha zone valves are going to be even more present in the US.
Uponer
@ November 26, 2009 4:51 AM in would love your feedback!
I think you guys feel through the cracks when you cleaned house a few years ago. You still make great PEX but have really seemed to lost your steam in the market place. We no longer get our web leads and have not been mailed or contacted about any new products.Quite disappointed of Wirsbo (opps) Uponer as a company.
Just my 2 cents
And we do a lot of Uponer

@ October 18, 2009 10:30 AM in Large Peerless Purefire job...
Just finished a large Peerless Purefire job. Pretty nice boiler that wired, vented, and piped rather easily.We installed a total of 23 boilers between 5 boiler rooms. Each boiler room had two dedicated domestic hot-water boilers that tied to a large indirect. The remaining boilers in the room where for central heating.

I just want all the wallies out there who know Cousin Nick to say a little prayer for him tonight before you go to sleep.Last week he was diagnosed with hotchkins lymphoma and meet with his oncologist today. He starts kemotherapy within the next two weeks for the next four months, having a treatment every two weeks. At that time his doctor has told him he may not work because of how "dirty" our trade is and the potential of getting cut. And he will be out of work for a minimum of 6 months...
Nick's the good looking one on the left!
So sad

Here is a small solar thermal job we finished a few weeks ago! Really cool system that has been handling this two person residence well. we also put a Tekmar control on the boiler so it can be locked out during the evening..30% tax rebate
@ September 18, 2009 6:41 AM in 30% tax rebate for solar thermal
So this would also cover the new solar indirect?30% tax rebate for solar thermal
@ September 17, 2009 7:07 PM in 30% tax rebate for solar thermal
In the summary of tax credits it statesAt least half of the energy generated by the “qualifying property”
must come from the sun. Homeowners may only claim spending on the solar
water heating system property, not the entire water heating system of
the household.
The credit is not available for expenses for swimming pools or hot tubs.
The water must be used in the dwelling.
The system must be certified by the Solar Rating and Certification Corporation (SRCC).
I don't understand the "Homeowners may only claim spending on the solar
water heating system property, not the entire water heating system of
the household." part
