need help with wiring

@ March 22, 2014 7:14 PM in indirect aqua stat?

At the point of wiring it all together. The Tekmar 161 setpoint is able to communicate on the house network using 4 wires. the manuals don't tell you how to wire it up. it shows how to do an aqua stat or a set point but not a set point to the dhw terminal. can someone that knows tekmar controls tell me how to do the four wires?

thank you

i'm no artist...the box with the x is were the taco sentry zone valves are


@ March 10, 2014 4:02 PM in Flow check.

So you are saying with zone valves and checks in the circs I dont need any check valves installed...


@ March 10, 2014 2:26 PM in Flow check.

going to run 1 1/4 out into micro bubble than to tee 1 to circ for indirect with spring check on return to boiler, after the tee the main line will have the main circ for the zones  going up still in 1 1/4  to the zones taking off  in 3/4 with ball valves. At the end of the zones will be taco sentry valves going back to 1 1/4. This will go down to boiler with a spring check were the return for the HH will meet then both go into boiler. the water feed will be on the bottom of boiler with the drain. I have not decided on putting the expansion tank on the boiler or the bottom of the bubblier, leaning on the boiler by the PRV.

Short of it is the tekmar set point will give the best performance all around becouse everything in the system will be nt4 and able to share all info. That way its one item on SS tank, less things less trouble.

what to use

@ March 10, 2014 1:43 PM in indirect aqua stat?

any old aqua stat work or would it be better to use tekmar set point 161 so they can all talk. If i just use the aqua stat will i need a sensor to know my hw temp?

Flow check.

If the circ. is pumping away from the boiler and the expansion tank and it has a check valve, I use taco sentry zone valves and spring check valves on the return do I need a flow control valve to stop ghosting

indirect aqua stat?

@ March 10, 2014 12:03 PM in indirect aqua stat?

If you have read any of my posts you can see I'm doing a lot to my system. Now I'm still ordering parts and supplies until i have everything to do the job all at once. So the question for today is I'm going to use a Tekmar 420 with the 335 to run my boiler and zone valves, do I need a aqua stat for my SS30 or just a sensor wired into the 420 controller

pvc hangers for PAP

@ March 7, 2014 7:56 PM in pvc hangers for PAP

Can i use pvc conduit hangers for my 3/4 pap?  Ive looked every were to day and nobody stocks 1 pex talons in numbers, the ones that do have are 60 cents a piece.(5 at this supply 6 at this one) So if i order they will be in on Wednesday but still expensive. Can i go to the big box store and pick up a couple of bags of 3/4 conduit hangers for $8 a 100 and use that? I'm running 180 on the coldest days in my baseboard.

pex al

@ February 28, 2014 4:51 PM in pex size

did some looking and found the fittings to use the pex al that didn't involve first born.

the fittings have o rings do i worry about them going bad? the best warranty on comp fittings is 3 years, I'm assuming it has to do with the brass from corrosion

Will i have to do anything special were the pex al goes through the floor or just treat it like copper. and what about hanging it some as pex .


@ February 27, 2014 4:15 PM in pex size

How do you make provisions? would you hold tight in the middle and let expand out. I want it to look nice in the crawl space.
My longest loop will have 10 fittings including the ends, will the drop be to much, should i use 1" to make up for it.
not getting into all the mumbo jumbo about extrusion process, other than flexibility whats the diff in a or b, and does it effect using it for copper fin tube?
The pex al pex is good, but i have ring clamp tool and cant justify the other for 30 connections

pex size

@ February 26, 2014 5:20 PM in pex size

to best match baseboard should i use 1" or 3/4 "
the pex is smaller and then you put the fitting in and make it smaller yet. i wondered if this had a measurable effect on the flow.


@ February 26, 2014 4:11 PM in How, exactly does

what about the wilo stratos eco 16 rfc. I'm looking at this one for a small 4 zone setup in my home. What i under stand it constantly changes based on demand.

your right co no 2

@ February 26, 2014 3:52 PM in How many of you carry

sorry my brain is much faster than my typing. Than why do they make detectors that plug in outlets?

mixing of gasses

@ February 26, 2014 11:52 AM in How many of you carry

If that was the case, why do they recommend co2 detectors be mounted low. 
the specific gravity of co2 is .966 but air is1

I'm just a homeowner but i think that you should be properly trained in what your doing for the safety of all involved.

after more reveiw

@ February 23, 2014 11:35 AM in superstor or amtrol

After doing a lot more searching i have decided on the htp superstor. My next question would be about the size do i need a 30 or 45? I will be using a Biasi B3 boiler, 1 bath room in the house and the biggest user of hot water is the big tub ( it uses 3 gal a min. just on hot. My hot water now is tankless in the boiler so i have no idea what size to get. The tub would pull the water through the boiler than the water would heat up so i never opened it all the way. my cold water sets in a tank next to wood stove so the water is at 60 most of the time.

superstor or amtrol

@ February 21, 2014 9:04 PM in superstor or amtrol

I'm putting in a indirect, so I've been doing some research trying to decide what to get. Both tanks seem to have a reputation for leaking in the past, so i was wondering if they fixed the issues.

slant fin

@ February 14, 2014 4:54 PM in biasi b-3

I used slat fins after i posted about the discrepancies in the calculators. i ordered the boiler yesterday just waiting for it to show. then just have to figure the how i want my zones to go and what controls to run. its so confusing going with this new stuff, if i just put it in like the old it would be easy but a waste of time and money..


@ February 12, 2014 8:48 AM in heat loss calculators

The only two realistic choices is oil or propane.I'm already set for oil with the tank inside, for propane id want the tank buried but then that's a lot of work and extra expense. i have looked into Geo but that would kill my small basement with all the stuff needed, the basement is only10x18 with freezer washer and dryer water softener stairs water tank pump ....
