I couldn't agree with you more...

@ June 30, 2007 12:33 PM in Opinions needed on porch decking materials

I built a screened in porch several yrs ago and used 1x4 T&G mahogany in there and it looks great, but it is covered. Next to it on the deck and stairs down to the lawn I used the 5/4x6 mahogany (not the same species...apparently), and it jsut looks like hell. It would just burn off the various finsihes in a heart beat. As well, I put a really nice mahogany rail on the deck and stairs. It too look terrible. I'm fixin' to go composite too. I've got a bit of time for this (have to do the living room, master bath this year)but I'm getting started on the new handrails.I'm going to get some 3" pipe and weld up the posts and railings for poowder coating, then going to use a cable systemn for the "ballusters". The 9/06, Fine Homebuilding mag had a good article on this. For info on the cable rail check out www.cablerail.com, www.ultra-tec.com, www.atlantisrail.com and www.secosouth.com. With three boys you probably want the vert cable so it isn't a ladder to nowhere.... Good luck!

I will be happy to meet to examine the plans/site etc to advise as to the application of the on-demand water heater and the Rinnai DV wall furnaces. May I help you? My cell is 617 834-8751

Not totally familiar with the Takagi, but...

@ June 19, 2007 7:02 AM in Takagi on demand hot water design question (milne)

The problem is typically the minimum flow/temp rise issue. Whenever anyone has a problem with a "water heater" of any type the conventional answer is to "turn the temp up". If you are looking at a low flow faucet and some other restriction, in this case the tempering valve, you should turn the temp down with on-demand. The higher water temp will require less flow to mix to the proper temp, dropping below the minimum flow to actuate the unit. See how your domestic circuit runs iwth the temp valve set at 120 and the unit set at 120. In fact, if you by-pass the temp valve and put 100% capacity to the dhw loop does the unit provide enough hot water to satisfy the customer? That answer will help define the problem and solution. Avoid tempering valves with on-demand water heaters. It is about impossible to get a high temp heating circuit and low temp dhw to peacefully coexist.

Bull Headed Tees

@ May 1, 2007 12:39 PM in Bull headed tees

I was visiting a job at a beauty spa with two Rinnai Continuums piped to a Aqua Booster tank with a 009 Bronze pump supplying the Rinnai's. The Rinnai's checked out fine. Gas pressure was excellent and dropped only .5" with both units working. All mechanical components were working as designed but the system would not run. Here is what I found. The two Rinnai's were about 75' away from the tank and stuffed up into a dropped ceiling, to which I must say that just because they fit...does not mean they go there. The riser pipe came up to a bull headed tee on the cold feed. The pipe went around to the rt to feed one unit and around to the left to feed the other unit. Hot water pipe returned by the same path, met on the run of a tee and fed down to the tank. If one unit was isolated, the other would fire up fine and operate as desired. This was true of both units. When the A-stat called it made the pump, which created the flow which turned the turbine, inducer, spark, gas, flame (in a very short time)and then both units would go into error. The problem was that the Rinnai's were starting fine on the flow, but when the two hot pipes (flows) came togethr into the tee (about 12' of pipe on each side) the flows collided and stalled the flow turbine right at start-up. Perhaps a better way to say it is that it created a kind of recoil. This took place in a short time frame. It would stall the flow turbine just as the board was still proving flame current and properly lock out the unit. When I left the contractor was re-piping to feed from one side or the other and reverse return. I do not understand why folks would try to balance flow with bull headed tees. I'm also interested to see what the flow increase is from the pump. You can read the flow to a tenth of a gallon on the touch pads. This was a new one to me.

Just a question

@ April 28, 2007 11:20 AM in SS Chimney liner

What are you venting? 8" is pretty large. You might be able to downsize.

Mod/con choice

@ April 22, 2007 7:32 AM in Mod/con choice

If you were to pick a new gas fired, boiler for your home for a combination baseboard/radiant system, heat only, 80kbtu load, what would you pick? Why?

Make sure

@ April 8, 2007 8:39 AM in Oil Vs. Propane

if you go with propane to buy the largest tank you can and bury it in the yard. Out of sight, you own it and you have enough storage to buy when you want. I'd go propane too.

@ March 25, 2007 6:43 PM in Tjernlund power vent

If 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

Recirc & on-demand

@ 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!

Ah, spring is just around the corner

@ 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.

Rinnai 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
