@ April 2, 2007 5:48 PM in outside side wall mounted condensing units?www.sauermann.us They make an excellent bracket system. Usual disclaimer applies here. I do represent them.
@ March 25, 2007 6:43 PM in Tjernlund power ventIf the system has been giving problems, definitely clean the wheel on the SS2, clean the air tube as mentioned above and clean the boiler. Start with that as a baseline. How is it wired. Tjernlund is trying to get the wirng to go b1-b2 on A-stat to SS2 to boiler. Put all the calls in series, that way you don't have the various controls fighting each other. It happens. Add combustion air to this system. You are fixing someones elses leavings. By the time you try once or twice unsuccessfully, the system is now yours. The Enforcer will only operate on a call for heat. It is the only unit that is designed to provide combustion and ventilation air and it has a positive lock-out. All manuals are available at www.tjernlund.com. Call tech service at 800 255-4208. Good luck
@ March 20, 2007 8:55 AM in Tankless with recirc?......(JohnNY)When I intially installed my Rinnai I put it down by the boiler/indirect. Whoever plumbed my house eons ago put the master bath at the end of the hw line...so, I wait, with either the boiler or indirect. Having recently remodeled two of the bathrooms I took the opportunity to move the Rinnai right under the bathrooms and to re-pipe with a manifold system and 1/2" pex to each faucet. Basically I eliminated all the 3/4" hw piping. Shorter pipe runs and less vol equals better comfort, shorter wait and better economy. My point is that when installing an on-demand wh, check out the whole system/house and do not simply install the on-demand where the old water heater was. Most water heaters/indirects are a slave to the chimney location. My dv Rinnai doesn't need the chimney. Go ahead and bid the original location (A). Go look for the best location for the new on-demand (B). Tell the customer that B may likely cost a bit more to install but will give the best performance, comfort and economy longer term. On new construction this works too as you can reduce the amount of HW piping dramatically, if you can find the "right" location. We take recirc for granted as a solution, but it wastes a huge amount of energy. Copper pipe is just a piece of fin-tube baseboard without the fin. It is still an excellent hx, and our pipe insulation is not very high R value. I vote to eliminate recirc whenever possible to get the best out of the on-demand wh. I represent Rinnai and the jobs I visit are typically undersized gas lines and water heaters installed on the dark side of the moon.

@ March 4, 2007 6:42 PM in DAIKIN split system A/C ?I try to post my affiliations here just to keep things square, although I got out of line a couple weeks ago and was politely, and correctly, put in my place. Mitsu, Sanyo, Daikin all make excellent equipment. At this time I will be happy to compare anyones equipment to Fujitsu. No bombast, which for me is saying something, just spec to spec. Fujitsu will win, and they are less expensive. Great value! For a 1.5 ton load I would recommend the 18RMLQ. It uses 2 9k evaps. It is still the hp model but the heat does not have to be used...but once you see how it runs you will use it now and then. All of our multies are hp. I suggest a dual to get the benefit of two fans for air circulation. Your other option is to go with two single 9 or 12 k units (models 9/12 RLQ). The most efficient units in the business at 21 seer. They will modulate down to 3,600 btu. For comparison the dual unit goes down to only 5,500 btu in the 9k unit. I think in your home it will be important for the dehu to get the lowest speed operation. Check the Fujitsu site and compare the min/max in H&C. Check the moisture removal rates and also check the min/max on amps. Check the line set length on both the duals and the singles. Great flexibility...but every house has a personality. Did we converse here last year on your house? If you can wait a few weeks I will be in VT and can visit should you care for me to do so. If you want to move more quickly I have an excellent guy in VT who can advise. Your call!
@ March 3, 2007 5:40 PM in DAIKIN split system A/C ?And the AC questions begin. Dakin has pushed strongly into the variable speed/inverter commercial products first and are only really trying to market their smaller size units this year. I say that from a competitors view as I represent Fujitsu in NE. Fujitsu is running pretty much 3-5 seer points above the competition. Buy the heat pump units. They are performing beautifully in the shoulder season (spring/fall)in the heat mode. In warmer climes they can do well year round. Also with the hp models you get the IAQ features. Full specs and all manuals are available at www.fujitsugeneral.com Smaller, quieter, longer line sets, smaller evap, more efficient, oh, and typically less cost.
@ March 2, 2007 4:23 PM in fireplace optionsRinnai is making a FP that is DV which requires only a 4" hole and the unit is 20" deep. It modulates on both the gas valve and house blower and is over 80% eff. Check www.rinnai.us
