@ 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.
@ October 8, 2013 11:23 PM in Any concerns about Rinnai boiler?The pump modulates before the burner to maintain a 36* delta T across the llh
@ October 8, 2013 10:35 AM in Any concerns about Rinnai boiler?Variable speed pump. The E series Combi's have a 3 speed Grundfos set to high to drive the plate HX for DHW. With the vari speed pump and LLH all that pump does is modulate flow first and burner second to maintain the delta T across the llh. That variable speed pump is also a part of the indirect equation for proportional DHW Priority when using the 3way valve.
@ October 7, 2013 10:58 PM in Any concerns about Rinnai boiler?ATAG, an award winning Dutch manufacturer of boilers and Rinnai share technologies and Rinnai supports the sale, marketing and technical support of the ATAG boilers in NA.
The 95+% efficiencies are real. Your concerns about high pressure drops and low flow rates show that you are not familiar with the product and it's features. To provide ease of installation and system flexibility all Rinnai boilers, with the exception of the new E50C, are supplied with a low loss header. That handles your concerns I presume.
The indirect can be piped conventionally or Rinnai's optional 3-way valve allows the use of the boilers primary pump to drive the indirect. Use of the 3way valve offers proportional DHW priority.
As to the cost, I think that if you review the features of the product you will have to acknowledge the excellent value Rinnai provides. Perhaps you should try a few and report back.
To the original poster I was the Rinnai rep in your area for twenty years, so I must acknowledge my bias. That said, I heat my home and hot water with Rinnai products.
@ September 29, 2013 9:53 PM in Noisy Carlin EZ gas conversion burnersAbout 20 yrs ago I was with Pete Axeman at his plant and we were looking at one of his boilers with a Carlin gas burner on it. Very noisy! Pete said, "Watch this". He put a 1' section of 4" gal vie pipe on the intake and I couldn't believe how it quieted down. We then tried it with a 4" 90 and the effect was the same.
@ September 22, 2013 10:18 AM in ac system design helpYou could do a multi unit and use the small concealed air handlers. They have very low static so position to minimize ductwork. Your other option is a minisplit and add a few Tjernlund Aireshares.
@ September 19, 2013 9:40 AM in High flow shower headsthe number of people who buy these high flow fixtures with nary a thought to what it will take to feed them. Anyway, 3- 199kbtu condensing tankless will handle it all day long, or until the septic system blows up. To me, tankless is the only way to do these. you end up with multiple units but you have the capacity to use the fixture for as long as you are doing your thing in 17 fpm. When you step out of the shower, Junior can wash his hands and the system will fire as low as 10.5 kbtu. No standby losses which is the problem with big storage.
I once had a guy proudly tell me that his shower head cost $5500. Total flow in the shower was 25 gpm. I proudly told him the equipment requirements to feed his play room. He was upset.
@ September 17, 2013 11:45 PM in Rinnai parts neededDescription of the unit, it is certainly worth getting "available" parts to repair. The 1001 hasn't been produced for at least 15 yrs. As parts cycle through the recommendation would be to go with a newer modulating burner and fan unit, if your particular need cannot be fulfilled. If I was told by distribution that a part was nla, I'd check direct with the factory before replacing...depending on the general condition and history of the unit .Some parts are just NLA at this point.
@ September 10, 2013 12:02 PM in Rinnai parts neededNelson & Small. 207 775-5666 in Portland, ME. They were the biggest sellers of the 1001 back in the day. That product hasn't been manuf for 15+ yrs now. I just happen to be at Rinnai today, so I'll go see what I can find, if it exists.
The 132 Air inlet elbow is available. The 1004F 520X03 is the right part number. The FOT-40-3. We just looked it up and you can use a part number 1004F-530X01 and use the current vent kit for the 1004 the FOT-151. The 151 is the standard vent which will adapt from a 4 1/2" to 9 1/2" wall thickness
That's the best I can do!
@ September 8, 2013 11:07 PM in Air compressorsKinda sorta off topic, but thought I'd ask. I've got a substantial structural steel project here at the house and all my compressor filtration gear got lost in the move west. What do you use to filter and dry your compressed air? I don't want to pump a bunch of moisture into my plasma cutter. Thanks for the help
@ September 1, 2013 10:52 AM in Electric Heat???Would be a propane fired Rinnai Energysaver. Easy install and easy to take with her on the way out.
@ August 25, 2013 10:51 AM in centro therm pipingI think, is not melting the pipe. Your problem is that when you have a fire you will be pulling the smoke into the intake of the boiler, and it will not be happy. Somehow, you need to separate these two systems.
@ July 25, 2013 9:45 AM in I Often WonderThe best approach is the direct approach. Call Jeff Pope and ask him. He's a good guy and he is accessible!
@ July 18, 2013 12:07 AM in Rinnai boilerRinnai has a few different combis. The 75 & 110 use a plate HX for DHW. The 175c has a 6 gal indirect and the new Q85 & Q130 Premier's have a 24 gal indirect. What were you quoted?
