Indirect temps

@ July 9, 2013 7:06 PM in Indirect temps

What temps do you generally set your indirects? Do you add tempering valves on them?

I'd suggest

@ July 4, 2013 4:03 PM in Buy wall furnace or use existing radiant heat?

A Rinnai Energysaver, possibly 2 in each apt. I'd also look at Tjernlunds Airshare room to room fans. To get away with one unit positioning will be critical.

My general disclaimer, I represented Rinnai in my business for many years and consult with them still, so bias noted. I do heat my home with them however;)

Appendix E of NFPA 31

@ June 25, 2013 9:12 PM in 6" Boiler Exhaust w/ 5" chimney liner. how bad is this?

Bob, you are correct that the Appendix is "not a part of the code". That said, over the years I've talked to many people and been involved in many installs where the sizing in Appendix E worked perfectly. Many of those used 4" liners or pellet vent.

These tables were initially put together by Rich Krajewski and John Strasser at Brookhaven. I think they should have been adopted in '93 or '94 when first presented, and when I was on 31 I voted for them. Instead, 20 yrs later we still do not have lining standards for oil. The code says it must be the same size as the breaching. Not much science that I can see behind that rote statement. It's just the way it has always been.

Contact the manufacturers

And their local reps. Of the majors, Fujitsu, Mitsubishi and Daikin, Fujitsu is in N NJ and have regularly scheduled trainings. As well, the local reps, Wales Darby have a training facility and also provide training.

I think this an excellent move on your part. Become really good at these mini-split systems and specialize in them and it is, in my opinion, all up-side for you. Good luck!

I'm surprised that you are almost always at the minimum

@ June 9, 2013 7:22 PM in Ductless AC / minimum line set lengths

I will reference Fujitsu as that is what I know best. Laying the line set off in a serpentine manner behind the unit is best. Coils are absolutely a no no. Traps oil. Increasing the line set may be convenient for you but if you call engineering asking for a charge on an up sized line set they won't even talk to you. They will simply say install it per the specs. The mins are 9' for 9, 12 & 15 kbtu units. 18 and up is 16'. Confirm those numbers?

The first year the inverter units came out, we were told that you could get a resonance out of the evaporator if the line sets were to short. Some time later I was with one of the Japanese engineers and asked him what the noise was. He said it was the compressor telling you it is unhappy.

I'd suggest sticking to the specs for warranty support.

Resurrecting a 9 yr old thread?

@ June 7, 2013 11:41 PM in Rinnai Water Heater Leaking

You can ask a "new" question. You say the pressure relief pipe is leaking. I have to say that on a tankless that is exceedingly rare, at least in my experience. What temp are you running, model #. With a leaking prv after 13 mos, I'd replace the valve while also checking gas pressure and water pressure. Do you have high water pressure? Temp and pressure being directly proportional adding temp to a high pressure system might trip the prv

Do the suggested flow test

@ June 4, 2013 8:00 PM in Tankless meets Jacuzzi: who wins?

And determine the vol of water needed to fill your tub. A 199kbtu condensing tankless will make around 6gpm at a 70* rise (50-120). If you sit in a bathtub over 105* you are no longer bathing, you are parboiling. So at a satisfactory bathing temp you should be in the 6.5gpm to the tub. Will the tankless fill the tub? Yes! How long to fill the tub you have to test and report back.

Every time...

I begin to think I'm a pretty smart guy I find myself in a place like this!

Done

@ May 21, 2013 6:10 PM in Kitchen sink vent

& Thanks!

As an option

@ May 19, 2013 9:52 AM in Floor mounted tub spout

I had a Victoria Albert tub, the Asia model, which is their clawfoot type. I used the block bases though. I also used their free standing "Faucet Tower". It worked out pretty well...if you have the space.

I'm in the middle of the kitchen and bath(s) re-model and found the same tub as a display close-out. Bought it again and this time will use a deck mounted faucet next to the tub at the center. I will have to kinda shape the wall protrusion, but it should be a better detail.

Those long faucet risers just give me the willies. Good luck with your install

Yeah, you screwed me up

@ May 19, 2013 9:43 AM in Order of Catagories on the Wall

I kinda had an order that I've been running the topics for a long time. The Wall, boom. AC, boom. Radiant boom. Gas, oil, dhw, boom boom boom. I could scroll the topics with my eyes closed after a lot of practice. Now I have to really pay attention again. Nice going!

Kitchen sink vent

@ May 18, 2013 10:26 AM in Kitchen sink vent

I have an 8' window in the new kitchen. The kitchen sink is centered in that window and the window is at counter height. This would give me a 5' vent arm below the rim. How would you vent it?

Based upon a few

@ May 15, 2013 9:41 AM in Plumbing Forum?

of my recent posts, it would certainly be helpful to me;) I came up through the plumbing trade and was a contractor, but not having worked with the tools for a long time, why, things have changed. I would like to see it and will contribute as I can.

Individual room control

@ May 12, 2013 11:47 PM in What is the most effective heating system for Schools & Intermittent use buildings?

I'd suggest that you look at Rinnai Energysavers in each room. Modulating gas valve, modulating blower, programmable stat built in, very durable. Each teacher controls the temp in his or her own space. Check it out.

Any advise on pex....

@ May 10, 2013 10:53 AM in Any advise on pex....

I'm re-piping the house and running Uponor pex. I have the Milwaukee Expander. Wow, what a tool! I was able to 1" with the expander that I never could have done with the manual kit. Anyway, it is a manifold system. Longest run of hot water from my tankless will be 16' ;)

My question is, how are you terminating under the sinks, toilets for a secure mount? Any suggestion, much appreciated. I'm a copper guy by training and inclination, but water quality issues pointed to pex here.

I would never add ductwork

@ April 21, 2013 8:03 PM in Radiant vs Forced Air

to an existing home. IN fact, I would never install duct-work n a new home. You basically have to tear the house down to do a "good" install. I would recommend that you move ahead with the boiler install and if you need cooling with a very effective heat side as well, that you look at mini-split heat pumps. Muuuucccchh more efficient, ultimate in zone control and quiet.

Fujitsugeneral.com and Mitsubishi.com are the two top brands.

BTW, you don't say where you are.

@ March 22, 2013 10:42 AM in Noisy Carlin EZ gas conversion burners

With Pete Axeman in his lab and he was showing me the Carlin gas burner. It was very loud. He said, "watch this", and put on a 1'section of I think it was 4" pipe on the inlet and the burner quieted right down. Really an amazing difference. Maybe there is something here for the EZ as well

Yes, it is certainly annealed

@ March 8, 2013 10:48 AM in For your entertainment...

It was a very hot fire. I went over to bladeforum and got some suggestions on how to re-harden the ax head. It is back in something like its mild steel form. Also, S&N being out of business I am going to have to unlimber the spokeshave and make a new 18" handle. Just beginning the re-model/addition of new kitchen and bathrooms I need more projects.

Keep in mind

@ March 7, 2013 5:56 PM in Duct vs Ductless Air Conditioners

that your current ductless system is "net to the space" and there are no duct losses. Given the increase in efficiency of the mini-splits and the heating performance increases at low temps, I'd upgrade the mini-splits and give up on the thought of ductwork. What I did is pull my ducted system and install mini-splits. I put a single 25 Seer unit in the primary living area and a dual unit in the upstairs bedrooms. Adding an addition this spring for new kitchen and new bathrooms I will put another super efficiency unit in the common area of the kitchen and be done with it. Personally, I will never put ductwork into my house again.

When you do something this boneheaded you have to be able to share it with folks, so here goes. Yesterday I was building a fire in Vermont Castings Encore and my daughter arrived with my sweet little 18 month old Grandson. My wife and daughter were chatting away, as they will, in the other room. While I was getting the kindling set to go, I found that I had to go back outside for some larger wood. The lad was transfixed by Grandpa's efforts. I had my very nice Snow and Nealey hatchet next to the stove and realized I had to find some place to put it where the little guy couldn't get his hands on it while I was outside. What better place than to temporarily place it into the fire box. I'll pull it out when I put in the larger pieces. All good! As I am bringing the wood in the girls decide that is a good time to pepper me with questions, demands, suggestions, etc. Girls being girls I guess. So...,you know where this is going...I finish making the fire, light her off and away it goes. A while later I begin wondering where the hatchet is and go in search of. I could not find it and by now I have a real nice fire going. Dreading what I might find I go over to the stove and cannot see anything resembling a hatchet so I let it go. I let the fire go out overnight and this morning while cleaning up the ashes, I find my hatchet head in the ashes. I thought for a while of hiding the hatchet head, but this is just to good to keep to myself. I just showed it to the girls and they are ricochetting off the walls in hysterics. Every time I begin to think I am a pretty smart guy I do something like this!

By the by, if you are in need of a good hatchet, Snow and Nealy make excellent products. I'm going to buy the small splitting set with hatchet and small splitting maul...and a new handle. I'll give the new hatchet to my daughter so through the years, every time she touches it she will get a laugh. I'll re-temper the edge, sharpen and re-handle and hopefully I too will get a laugh every time I grab the darned thing.

On the brighter side, the little guy thinks Grandpa is OK, and in years to come I will tell him this story too.
