@ February 10, 2012 11:05 AM in Grossly over sized furnace but properly sized a/cThe homeowner can throw a bunch of money at a very poorly designed and likely installed system and it still will not work correctly or efficiently. Put a properly sized multi or at least two stage furnace in, see how the comfort is and modify from there. There are times that you just have to sit the customer down, look him in the eye and give him really bad news. It will be better for you too, I think!
@ February 3, 2012 9:33 AM in straighting out a system ,what to do?Clammy, I won't try to help with the piping. I kinda met myself coming around the corner trying to understand what you are faced with there;) Something that may be of assistance to you however in demonstrating sealing/insulating methods to the homeowner is an article in the current Fine Homebuilding. Martin Holladay, wrote, "Air-sealing a Basement". It gives good details on sealing the rim joists. Good luck!
@ January 29, 2012 1:54 PM in Need about 18,000 btu's to heat small apartment any ideas.Nets out about 17,500 btu's. This is one of the ideal applications for this unit. have to deal with hot water in another way. Other heating option is a 410a mini-split.

Worth a read.
@ January 27, 2012 11:21 AM in noritz tanklessunless it proved necessary. Every system has a personality and a very small percentage of the units (100k+) I've been involved in required an expansion tank. If you are worried about it, place a plugged tee in the piping to accommodate your expansion tank should it be proven necessary.
@ January 23, 2012 11:26 AM in Noisy tankless heaterdisconnect the radiant tankless and use the tankless as a water heater as it was intended. Put in a proper boiler for the radiant. You will be happier and so will the equipment. Generally, groans on start-up are fluid restriction, possible flow control valve problem, crapped up HX or gas valve problem due to inadequate gas size/pressure. Or maybe a vent issue.
@ January 20, 2012 10:54 PM in Monitor boiler partsNelson & Small, Portland, ME. 207 775-5666. If they don't have them they can likely direct you to the other Monitor distributors. Isn't Monitor still in business
@ January 20, 2012 4:39 PM in Rheem or Bradford White ?Are tank cos still making standing piot units?
@ January 20, 2012 4:26 PM in condensing heat boiler or heat pump?No ductwork. Keep your steam system operational and push the majority of your heat load onto the mshp. Ac will be done by them also. Great zoning, comfort and economy for both your heating and cooling needs.
@ January 8, 2012 9:16 PM in Power Venter QuestionsIs that when your "system" is being cleaned, "every couple years" that the power venter is getting the thorough cleaning treatment as well as the burner/furnace. Frequently the power venter is ignored.
@ January 4, 2012 9:48 PM in My setupTell us what you have, fixtures, location of hot water source vs hot faucet locations, fuel current and desired. What are your goals? Future load increase? How many people? Narrow it down for us?
@ January 3, 2012 7:54 PM in How to Value a Fuel Oil Businessthis can work. With the wrong person, well....! If you are interested in turning the business as mentioned before, you need professional advise. Start with your accountant and lawyer and have them talking so you can get the advise you need. LOTS of implications for taxes, liability, etc
@ January 1, 2012 9:12 PM in How do you handle this customer?What you have to do is to tell them to have a bit of faith for a couple months and let the gas usage tell the story. I went thru this countless times with the Rinnai Energysavers that were sold in New England. With them, the stat was on the unit, which was in the living space, and the sensor is located 2" off the floor. As well, there was a room set-point number on the display too. In some cases it was as you describe, where a different setting from the original system drove them crazy. My favorite was when they would have a $3 pocket dial thermometer across the room and that would be their benchmark. I cannot tell you how many times I would cover the temp indicator with black tape and tell the customer that all I wanted them to do for a week was use the up/down arrows until they found the place where they were comfortable. Then and only then could they pull the tape. Whatever it read was their new benchmark. I did not care what it read. I only cared that they were comfortable, economically! The gas bills bore out the logic.
Net/net, you just have to get across that it is a new "system" and while it will keep them comfortable, it may do some things differently. The driving analogy works pretty well. Ask him what he drove at 65 mph in 1955. Then ask him what he drives at 65 today. Are they different? Good luck! Keep us posted on this please. I'm always interested to hear what works in these situations.
@ December 31, 2011 7:16 PM in Tablet use?Is my choice. Got one as soon as it came out and love it. I hardly carry the laptop any more. For me, when I was in a basement I could call up tech/troubleshooting info for that particular piece of equip. Really nice getting info when you need it rather than having to leave to get info. The kids got me an ipad2 for Xmas. Nice kids!
I have the wireless and 3G. A must in my opinion.
@ December 27, 2011 7:56 PM in Rinnai E110CP explosive ignition and low heatI worked with Rinnai as their rep for many years. I no longer do so, but over the past few years since the intro of the boiler, I solved ignition issues, delayed and no fire, by changing the gas supply. Turn off the gas cock and tie in a 20 lb cylinder of known good gas at the drip leg for the test. Certainly, I cannot say it is the gas, but with a new tank set, the change has worked. At this point, after all you have gone thru, it is worth a try.
@ December 21, 2011 8:29 PM in One for the (really) Old Timers!To that, but now, I'm such an old timer I can't remember;)
@ December 19, 2011 9:16 AM in CPVC vs pexLooking over the 3M Cuno site there is much to digest in water treatment. They don't make it easy. As well, I'll be looking into the piping suggestions. Much obliged!
@ December 18, 2011 5:56 PM in CPVC vs pexWater treatment is in the equation for sure, but also want an understanding of the options pipe wise. Much obliged!
@ December 17, 2011 11:01 AM in CPVC vs pexHave any of you used the CPVC water piping for domestic? Turns out I have a 6.2ph on my well, which precludes the use of my preferred choice of copper for the re-pipe of the house. The house is an old place with galvie...whats left of it. I just ran a new underground water supply from the well as well as conduit for underground service. I'll be replacing the old bathrooms once I get the permitting in place (my delay at this point, not theirs).
I had pressure drop problems with pex in the old house and don't like the idea of oversizing the tubing to overcome the bushing effect of the pex fittings, especially on the hot side. I've never used the CPVC for water before, but it looks like this may be the best option at this point. Any experience with the CPVC? I will look into water treatment as well. With the exception of the ph, the water is excellent.
@ December 5, 2011 10:53 AM in Rinnai Tankless Water Heaterit is probably 5 yrs old. It would be worth flushing the unit with 4-5 gallons of white vinegar. Using the service valves, pmp from cold thru to the hot side. Do not pump from hot to cold! Your description of the issue is a classic for an undersized gas line. The rumble etc. The unit is trying to fire and does so, but with a winter load, on your house and the whole system, the gas pressure is just a tad low. Teh unit knows what it wants to do but air fuel mixture is compromised and it will sing. If you are lucky it will sing a tune you like, but I've not found that yet. In the summer with reduced demand on the gas supply system the unit can do its thing.
BTW, when you flush it, make sure to clean the immersion sensors at the upper rt and at the hot water outlet. Two small while wires connect them. There is a very small O-ring on the sensor. Don't lose it;)
@ November 22, 2011 10:38 PM in geothermal worth the investment?Until you go to all the classes you can and have a very clear understanding of the features/benefits/costs you cannot make a reasoned assessment as to whether you should get into it or not. If, after all the training, you decide not to get into it, you will be better able to serve your customers needs based upon a solid background.
I did a bunch of them for the "very wealthy" back in the late 70's. I wouldn't put one in my house. I'd get really good at mini-split heat pumps, because they are getting better and better at a fraction of the cost/hassle...and with your savings you can put in a modcon with them, if you insist;)
@ November 19, 2011 11:42 AM in Chimney Liner-Insulated or Notdo it right. Definitely insulate the liner. This is especially so on an exterior chimney. If it is a straight shot I'd suggest looking at MG Dura-vents Duraliner. I represented Dura-liner a few decades ago when this product was introduced. I am working with it today on my new home where I found a full length liner in the old chimney. I have to add to it. I had forgotten what a neat system that was. IF you can get an approval from the manuf and AHJ to go down to 4" you can line with pellet vent. It is L-vent, double wall and an excellent liner system...again, with approval. At 38" I'll bet the 4" would whistle right along. Check Appendix E in NFPA 31. I cannot find my copy right now.
