Throw backs

Hey Dan, I loved the piece you wrote about steam systems and the guys still installing them. I did a job about three years ago where all the mains were removed, the boiler shoved in the corner and the radiators left on the floor. I had to relocate the boiler, figure and install all the supply and return piping, main vents and radiator vents as well as re-pipe and re-wire the boiler. The system runs on 12oz and is quiet as a mouse. Pretty close to a new installation in my book. My clients took great pleasure in showing the job to their neighbors who had told them to convert to baseboard or burnt air, cause "nobody installs steam anymore" You probably could guess, but I'll say it anyway - they found me through my FAP ad. The club may be bigger than you think ;-). To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Control settings and customers

@ September 10, 2006 10:43 AM in Indirect water heater temps

Hi John, Thanks for the advice, nothing worse than a customer who paid for a top of the line system getting a cold shower. Unless of course they were expecting it. I always explain to a customer that we really don't know how low we can go untill we have gone too far - than we have to back up a little. So far anyone who is wanted to use advanced controls has understood this and most become very proficent at useing their new system. A handfull prefer not to have to adjust things and then we use standard settings to insure the desired inside temps as well as maximum domestic hot water.

I have a Vitola 200 installed on a Vitocell 300 horizontal tank with the Vitronic 200 control. The control allows you to adjust the domestic hot water response and I have a 3 speed circ on the indirect tank. I am going to spend some time with my super heat thermometers and see what I can make the delta t across the coil do. Then I am going to find out exactly what all the coding in the Vitotronic 200 can do - the instructions don't get into specifics about every function. I would like to try to make the delta t of the coil as wide as possable and program the max boiler temp slighly above that and see if the tank can perform with a family of 4 not noticing any difference from the factory defaults. I will post results here when I get them. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Indirect water heater temps

@ September 8, 2006 5:10 PM in Indirect water heater temps

If an indirect water heater needs to supply domestic hot water at 120 does it pay to operate the boiler any higher than the domestic plus the delta T of the coil? The BTU input of the boiler is the same regardless of the water temp it is supplying (not talking modulating burners) so why run the boiler any higher than desired temp plus delta T of the coil? Have any studies been done on this? Anyone tried it on their own? To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Yes we should

@ August 31, 2006 5:27 PM in Not many using this forum

But I think we could use a little direction. The room opened quickly and many people had grand visions for what could be done - myself included. Just don't seem to know how to get started. Little Help? To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Thermal Bulb in the airstream

@ May 14, 2006 10:50 AM in Thermal Bulb in the airstream

Hello Professor, In another thread you mention that the TXV bulb should be insulated even if it is located in the air stream. I have purchased equitment that did not have an insulated bulb, and when I called the MFGs tech support was told not to wrap it. When the system was started superheat and sub cooling were exactly what they were supposed to be. To wrap or not to wrap - that is the question.

Great Day of training on the commercial line in Plainview yesterday. Brenden provided a lot of information and a peek at what's next. He also gave straight answers to all questions including the very rare " I don't know, but I will find out for you" Job well done! Always good to see and talk to Charlie as well. Thanks Guys!

Hey Ron

What kind of circ are you using? A UPS 15-58 on low speed draws 60 watts, and I thought that was pretty good, but you can't put 15 zones on it. Thanks Tom To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Good to see you

@ April 25, 2006 8:21 AM in Siggys Seminar

as well Glen. I trust you have spoken to your Doctor about the side effects, they may be able to make adjustmants if they know about the problems. Old school boiler guys tend to "suck it up" - not good. The form says Patient Complaints, your job is to fill it up.

Siggys Seminar

@ April 21, 2006 7:31 PM in Siggys Seminar

Went to Edison NJ for John Siegenthalers seminar yesterday. A very good day spent in the company of some very sharp people. Johns thoughts on electricity consumption made it clear that a hydro air system is the worst way to distribute heat energy - at least as far a BTU per watt comparison goes. It hit me in traffic on the way home that the best BTU per Watt ratio must be steam - fire the burner and let the vents do the rest. Score another one for the Dead Men. Thanks for a great day John!

The FM

@ April 9, 2006 11:11 AM in Buderus Mixing Station

module just provides low volt output for mixing - it can't tell what it is controling. The card simply opens and closes a mixing device to obtain the desired mix temp. If you use the BFU (optional) it tries to maintain constant circulation in the loop, with it you are getting feedback from the space as well as outside re-set. I have never tried to use the FM241 without a BFU so I can't tell you how it will work. I like the idea of using a single "brain" to control the entire system wherever possible. The 2107 is a great choice for a two temp system with an indirect water heater no matter what mix method you use. Buderus has great tech support available during normal business hours (8-5 M-F), and I'm sure they can resolve your issues with one call. 1-800-BUDERUS USA Let us know how you make out!
