@ December 29, 2013 11:31 PM in Large adjustble Monkey or Spanner wrench for boiler and pipe fittings?as long as we are talking about cold and useful tools I have to put this up.
I have the 6 & 9" versions and cannot believe how well they work. Good tools aren't cheap, but once you start with these you will not believe the quality & value.
@ December 20, 2013 11:23 AM in DanI have these scrolling issues too. Now I don't. I just find out more and more about these machines all the time. They say you can save stuff on them too, but I'm not sure about that.
@ December 19, 2013 10:30 AM in Combi boiler dhw and heat or dhw or heat"proportional" priority on some equipment. The boiler will make heat and on a call for hot water will shed some of its capacity to hot water. As the hot water load increases the heating side diminishes until it is all DHW priority.
@ December 14, 2013 7:46 PM in Hey Dan and my fellow wetheadsI think what you meant to say was, "Glad the Big hose is out, man"
Hmmm, that was fun!
Best wishes for a speedy recover and Happy Hoildays! David!
@ December 12, 2013 9:22 PM in Rinnai tankless woesIs available at www.rinnai.us. Select water heaters/model/documents and there it is. 10 indicates a high entering air temp. Could just need a cleaning. I'd suggest you call a dealer who has been trained by Rinnai to pull a service call.
@ December 12, 2013 11:30 AM in New install: choose propane or oil?There are a couple tens of thousand Rinnai Energysavers doing precisely what you are wanting to do. I'd suggest that you look into that option. I think you will find it to be very cost effective and provide the comfort your tenants are looking for.
@ December 1, 2013 8:22 PM in Rinnai tankless woesThe flow control valve. Just inside the filter location is a snap ring. Remove the snap ring and with needle nose you can VERY carefully pull the turbine assembly out. There are two sides forming the body and the impeller itself. Take pictures or at least carefully note the layout of the impeller and two body parts. It's amazing how I have tied myself in knots putting those back together. Re-install and try it. If it isn't that get on the tech line. Number is on side of the cabinet.
@ December 1, 2013 12:27 PM in Rinnai tankless woesthe inlet filter screen is to keep water borne debris from stopping the turbine wheel from spinning. The turbine is a precise measuring device. It is contained in the Cold water inlet valve immediately above the filter assembly Essentially it has an electronic pick-up on it that reads rpm and the units logic converts that to flow and combustion requirements to arrive at the set point temp.
@ November 30, 2013 5:44 PM in Rinnai tankless woesIs the likely culprit. If the turbine turns and the unit will not fire then the unit would code out 11, tried to fire and failed. Either the turbine is stuck or the flow control unit is bad.
@ November 29, 2013 6:18 PM in Rinnai tankless woesTurbine on the cold water inlet valve is stuck. Do you have debris in the inlet filter? If dirt gets into the turbine it is possible that the turbine wheel isn't turning. Everything tracks off that turbine
Oh, and the other cause may be cross connected H/C piping. It happens all the time.
@ November 29, 2013 6:13 PM in Indoor Pool HVACAnd they don't recommend that application" the problem is they are simply not designed to operate and survive that chemical content in the air. I'd strongly suggest you heed their warnings. They won't last.
@ November 29, 2013 6:04 PM in Carbon Monoxide Issues - HELP!I remember when Tjernlund designed the SSII power venter. One of the original goals was to take it to manuf and let them test it to be used without a barometric for their particular systems. That idea ran right into the time when all those manuf said they didn't need a supplemental venter. They could do it all with the burner. Sometimes it works well, sometimes not. I guess like everything else.
My suggestion to you is that you get a Buderus Rep in there with the technician. You are in MA and they have excellent representation there. Insist upon it. Make sure the guy coming out has his fast ball too and ask specifically for that "right guy" on this model boiler.
If you decide to build a chimney for this I would strongly vote for a factory built chimney. Do not use masonry. Masonry chimneys are 11th century technology venting 21st century appliances. Use as small a chimney as you can get approved by the manuf, and your local code official. I bet 5" would be just fine on this.
@ November 29, 2013 11:43 AM in Rinnai tankless woesBe aware that at the outlet of the fan there is an "diffusion" chamber. It is possible that a dirty fan would also indicate that the diffuser plate above the fan is likewise dirty and could require a brush/vacuum.
@ November 27, 2013 10:43 PM in I am so sorry for not answering my emailsIs that this gettin' old is everything it is cracked up to be. I hope things go well for you. Be well, be happy and you can now tease the heck out of your brother...although I understand how he felt.
@ November 27, 2013 12:11 PM in converting a two line system to a single lineA case of false economy. Trying to "hit & hope" that an oil burner will be properly balanced is close to assuming you have the magic formula to win powerball. You can make it run, maybe but Oil is costly. Get the most out of it and your equipment by having the unit set up properly by a pro. You will save money by doing so.
@ November 27, 2013 12:05 PM in Powervent shuts off after running for 1 minuteHas anyone serviced the SSI? If the blower wheel is packed and the sensing tube too, you can wire it properly and still get no heat. It is not uncommon for "some" service companies to tune up the boiler and never touch the power enter. They will then righteously tell you they don't service power venters. That was always a head scratcher for me. If the wheel hasn't been cleaned it is not uncommon for it to get out of round and require a new wheel. The UV1controller on that unit will have diagnostics on it and has adjustable pre/post purge built in.
@ November 27, 2013 11:51 AM in low ambient heat pump to supplement house heatingBut this is a good system upgrade in my experience. As noted, make sure you fully understand the performance of the particular model number you are lookingo at installing. Seer and HSPF ratings will vary dramatically by model from each manuf.
Also, from a cost standpoint, in my home I was going to go with a triple unit. In looking more closely, I ended up doing a dual unit for the upstairs bedrooms and went with a single hi seer/HSPF unit downstairs. Equipment cost was about the same. System performance and zone control is much better.
@ November 13, 2013 11:04 AM in small heat loadsMany of these types of conversions with Rinnai Energysavers. Simple install, individual control, significant savings. They have plenty of case studies on these systems.
@ November 8, 2013 10:40 AM in Gas companies in CT make big push into oil territorylet me start by saying that oil is great heat and a great industry. That said it is simply not competitive against other options, especially natural gas. If the oil industry is able to prevent this type of program the "public" will be more than a bit peeved at the lost opportunity to save money. They loose or loose. I think any oil customer in an urban area, those served by NG, is a major target for the utilities and the customer will thank them for helping them out. We are talking about heating homes and hot water for about a third of the cost of oil. What homeowner wouldn't want that? If you were a state or local representative would you try to stop this? I think only until the next election.
@ November 2, 2013 6:00 PM in Rinnai RC80HPI"Open loop Heating" only. Close loop apps are not approved. Don't do it! You are cruisin' for a bruisin'
@ October 28, 2013 11:06 AM in Door drafterbut, if you are having temp issues and the master needs a bit more ummph I would suggest you look at a Tjernlund Airshare. It is a transfer fan that has worked well.
@ October 11, 2013 10:23 AM in Loud snap when furnace turns on and offNumber one give you the satisfaction of knowing that the heat is on and you will be warm. Secondly, it does so on shutdown to give the the knowledge and comfort that the unit is off and not consuming any more energy. See, it is all in how you look at it.
I've always described it as, Kawumpf...heats on! And then, Kawumpf...heats off
Beyond that I cannot say as I'm not sure how the Rheems are set up.
