Tekmar and GSHP

@ May 21, 2010 8:52 AM in Tekmar and GSHP

I use tekmar stats and controls with my Knight Boiler and would also like to use them with my GSHP.  My heat pump supplies heat to five zones of IFR and chilled water to two Unico units.  One Unico is currently using a 544 for the cooling and connects to the Knight via a zone manager 336 and BRM 420.
I was looking to use two 336 zone managers for the five heat zones (with 541 stats) and the other cooling zone (with a 544) and a 420 BRM on off/on mode to control the GSHP.
I am having a little trouble getting my head around this.  Will these components do what I am describing and how do I handle the reversing valve with the 420 (not sure I can).
Any help is appreciated. 

Thanks

thanks Big Ed. currently the cold supply to the instant tankless runs into a storage tank and is preheated via de-superheater and then on to the water heater. Over night the water in the storage tank will reach set-point - 122*. So, first shower of the day you need to mix the hot way down. As the preheated depleats you need to adjust the temp in the shower. If I supply both the HWH and the storage tank with separate supplies and then put a mixing valve beyond them would the water temp be consistent? Or, if both are at the same set-point (tank and HWH) would it stop pulling from the storage tank as soon as the temp dropped?

supplemented hot water

@ April 18, 2010 9:34 AM in supplemented hot water

I have a GSHP with a de-superheater that heats water in a storage tank. This water in-turn supplies my instant hot water heater with pre-heated water theoretically saving gas.

The result at the shower head is very hot water early in the shower needing to be mixed down and then adjustments throughout until the supply of pre-heated water runs out.

My thoughts to correct is to put in a mixing valve after both the instant and storage tank allowing the hot water temp to be constant.

Any other ideas?

Thanks

Mitch, The house I live in is radiant/warmboard/geo. Love it. The house with the furnace is a house I rent out (landlord).

A little help. While my own house is all radiant i have a house I rent out and the furnace just died. My oil Co. / Heating Co. is suggesting a Bryant with a Rialo burner as a replacement. Not sure the make of the old furnace. Any comments or suggestions? Thanks.

Geo Buffer

Thanks, I'll check it out.

buffer tank

@ March 22, 2007 11:40 AM in Geo Buffer Tanks

I have a 5 ton geo. i have supply/return to the unit, return from the radiant loops and then two supply tappings. I think the tappings could be smaller as long as I maintain the two supplies to ensure flow. Thanks for the drawings.

Geo Buffer Tanks

@ March 19, 2007 11:55 AM in Geo Buffer Tanks

Can someone offer information, or send me in the right direction on these two questions? A) How do you size a buffer tank in a Geo system? Mine is water to water with five zones of radiant and 2 hydrocoils on it. B) A good scorce of tanks. I need five 1-1/4" tappings. My current radiant system is not a "closed" system dure to the buffer tank. This causes some problems with air in my system so I would like to replace the tank. The tank rrently a 40 gal tank handling five heating zones and two cooling zones. It was suggested to me that the system may perform better if I added more mass via the buffer tank. Thanks

@ February 3, 2007 7:31 PM in Money and Sex (from Mike T., Swampeast MO)

we need more information here. Has a money loss calc been done on this relationship? What kind of piping does she have? Is the live in boy friend condensing or not? What kind of sex...I mean heat emitters do we have? This sounds like a job that he should let someone else take on. Keep his money and run.

AC drain piped to

@ November 17, 2006 11:22 AM in Condensate Drain

I know this has come up before. My AC condensate was piped to the waste vent. Now that the cooling season is over, the water in the trap has evaporated and, yes thats right, a wonderful odor is wafting from the vents. Took me a few minutes to noodle that out but that is what it is. Any simple fixes that anyone knows about? Thinking of installing a much larger trap that will hold water through the winter.

Same basic setup I have

@ September 9, 2006 12:34 PM in Geothermal with mod/con?

That is the same basic setup I have however I use the Knight to provide primary heat to three zones and then use a Flatplate exchanger as a separate zone to preheat the return water for the geo as back up. the geo runs 5 zones of heating. This preheat zone works on an aquastat with the setpoint set below the low end on the buffer tank primary aquastat. This way, if it is cold enough that the Geo can't keep up and the buffer tank falls below the limit the Knight starts the preheat and brings the buffer back up to temp. I haven't worked out a "lockout" yet for the cooling season when the buffer is at 35*. As far as efficancy, this system is in a new "sip" house with Warmboard throughout. When compaired on a SF basis with the old house and Oil FA, it was 8 Cents better per SF. That was 3 years ago when I was at 14.5 KW. I am up to 20.5 KW now. Good old LIPA on LI.

Plumbing Problem

@ August 27, 2006 4:30 PM in plumbing problem

Was hoping someone could help me here. I am having a drainage problem, a blockage of some kind it seems, in one sink of my double sink bathroom vanity. It seems only to take place in the morning when I am shaving and brushing my teeth and no one is using the second sink. I can't figure it out but it maybe a black and white issue for the seasoned professional "wallie". I am hoping you guys can help me before the problem becomes catastrophic and I have to call in the plumber. If you guys come through it would be the cats pajamas. I have attached a picture that may help in the diagnosis. Thanks

@ April 28, 2006 12:02 PM in Question for all home owners

I did build the most efficient house I could. SIP, radiant with Warmboard, Geothermal Heat Pump with back up mod/con boiler. I choose not to give anything up but my free time and put in lots of sweat equity. I think the real answer is to educate the consumers so they can make the decision. So many have no idea what is available. That starts with open minded, progressive builders that are willing to try new products and ideas. There are so many out there that would never think of building anything but a stick framed house or put anything in it but a forced air system. I know a lot is driven by costs, however, most people I know take out a mortgage for a new house, usually for 30 years. Any up front cost (amortized over 30 years) for a more efficient envelope, built with new products that need less maintenance over the years, that is heated and cooled with more efficient equipment will cost you far less in the long run and is a great financial decision. Our seriously confused government could help by leading the way. On one hand they will offer tax credits and rebates for “Energy Star” building, solar installations and geothermal installations (which is good) but don’t require these innovations in the new and retrofitted government buildings. Our Local, State and Federal governments should all spec. energy efficient and environmentally friendly building techniques in every new or retrofitted government building. What’s that? It costs more to build it that way and our taxes will go up? Yes, that is true. But who do you think is going to be paying for that natural gas and electricity that will be used in those buildings. Our taxes will go up anyway to pay those increased costs…for years. Thanks. I feel better now!

@ April 17, 2006 2:05 PM in Geothermal for Radiant

I've got water to water geo with 5,000 SF of Warmboard radiant. Works great. Make sure you size properly. I use the Geo for cooling as well, hydrocoil. I compromised the heating capacity so as not to oversize for cooling. If I were to do it again, I would have put in two staged units. As it is, I suppliment and backup with a Knight 80.

Either you are very young or I am getting old (the latter I think) not to know Harry Chapin. That song holds a place in many a father’s hearts and serves as a reminder of how important it is to spend the time with your children. In Harry’s case, as posted below, he died far to young and didn’t get to see his children grow up. His son has followed in his footsteps but has not made quite the same mark on the music world as Harry. Hug your kids and SPEND TIME WITH THEM no matter how old. Harry knew what to do but didn’t get the chance.
