Visio Drawings

@ April 17, 2014 11:03 AM in Visio Drawings

I do Visio drawings at work for our mechanical rooms, for pricing and just for reference and as a sales tool. I am wondering who else uses Visio and if anyone has a good stencil database. I have acquired some from drawings and made some but would love more. Let me know. Thanks

High windows in heat calculations

@ February 12, 2014 2:49 PM in High windows in heat calculations

Do windows up at 8'-9' high play a big part in the heat-load calculations?

Where do I put them

@ February 7, 2014 11:32 PM in Zone valves - on supply side or return?

I put them on the return side. I see them on the supply side sometimes. I don't see any differences between the two. That is just where I prefer to put them.

Not Upinor from description

@ February 7, 2014 11:25 PM in Radiant heat zone not letting water flow

Upinor valves don't have manual levers or require a kit.
Also if you over-tighten one they will leak flow when closed

duel fuel boiler

@ February 6, 2014 11:56 PM in thinking of electric boiler

Electro Industries makes a top notch electric boiler that is set up with a duel fuel control.
If your electric company has a program for being able to shut off the electric and switch to gas this boiler is setup for that.

hard to say

@ February 6, 2014 11:37 PM in Radiant heat zone not letting water flow

Hard to say if it's frozen. If you are sure the motor valve is installed correctly and there is a little flow through there it could be frozen. The backup of water could just be pressure coming back from a frozen point.
What kind of motor valve do you have? brand/model

1. With a air/floor thermostat you can keep your floors at a minimum (whatever seems comfortable for you) while maintaining a constant air temp.
2. A ductless system is good for backup/air conditioning.

As far as the comfort goes, you can't beat it!

I use a eco testr Ph2. I bought it at a local gardening store. Works great, also purchase a bottle of solution.

how far will a nitrogen tank get me?

@ August 25, 2011 2:58 AM in how far will a nitrogen tank get me?

OK while airing up a radiant or snow-melt system dragging around my old Emglo compressor is a pain in the .... uhhh  back! I know Nitrogen systems can carry more pressure. Has anyone used this for filling a system and figured the cost difference?
Your thoughts please!

have you used the sensaphone units? Looks good.

Looking for good internet or phone based relay system

@ April 12, 2011 12:07 AM in Looking for good internet or phone based relay system

I am looking at installing a Honeywell AQ series control but am looking for a good wifi or landline based relay system. With the AQ it would work well for a vacation home. You could call into the relay system and turn vacation mode on or off.
Thanks

OHH YEAH!

@ November 22, 2010 1:46 AM in Taco 2006 EBV Zone Valves

I've installed literally hundreds of the EBV series valves. And I have replaced about 50 +-
with the updated heads (not the sentry) and have fixed most problems. I switched to Taco from the old White-Rodgers that you unscrew the green cover and then the 4 screws to take off the head due to not wanting to have to bleed out an entire system to replace one. and after installing hundreds of them all i've had to do it fix a few end switches on the old WR's. Makes me rethink my decision! interesting to see the new Sentry's

My experiences

@ August 21, 2010 10:29 PM in tankless gas water heaters

I have had a few experiences with them and not overly positive. Keep in mind the old adage you get what you pay for. I have installed many and would recommend
Rinnai first. then Noritz. I have installed many of both and think they are top of the tankless market.

other thoughts

@ August 21, 2010 6:15 PM in I will have a biler. Should I install tankless water heater?

I like tankless (Rinnai in particular) and have installed many. One issue I'm starting to see more is with high efficiency appliances. They just inject a small amount of hot water at a time and some appliances it's not enough flow to turn on the heater. I have seen this in washing machines and dish washers.
On another note I have installed the TT Excelence and have had no complaints with them at all!

OK

@ July 11, 2010 2:55 AM in Stat wiring

if I got this right. You will need more than 3 wires. you can run it from your ac unit. R,Y,C,G and be fine on the ac side. For heat you can hook up 2 wires W and C to a relay to power the coil side of the relay. use the dry side for your boiler TT contacts.

Hot Rod's right

@ June 10, 2010 12:29 AM in Small Electric Boilers?

I've used many electric boilers and found them to be crap!
I have been using only Electro for my electric boiler applications for about 3 years now and have had no problems.
Available with: outdoor reset
staging elements.
For use with duel fuel setups
QUIET ELEMENT STAGING!!
I don't work for them just really like them after using other brands!

Pool Question

@ June 9, 2010 1:40 AM in Pool Question

OK I have a job that has a 63,000 gallon pool which pumps aprox 80 GPM. I have a 400K BTUH wood boiler. I have two TT Titanium MF260 heat exchangers with pool flow in series and boiler piped in parallel. Can't figure on how to figure what I need for a flow rate through the boiler side of HX. Would appreciate some help.
Thanks in advance.

I believe Upinor has one.

@ June 1, 2010 1:39 AM in Heat Loss Program

I had one installed in my laptop which has since crashed and I have not re downloaded it. Check their site. It is FREE!

It's all in the stat!

@ June 1, 2010 1:20 AM in Radiant Heat under exotic woods?

I personally use Upinor 501S stats to monitor floor temps and set a max to make sure the floors don't look like like a scaled down version of surf waves. Another good aspect of the setpoint stat is that you can maintain a constant floor temp which customers love. Is usually a quick upsell in a house installed by someone else!

maybe?!?!?!

@ June 1, 2010 1:15 AM in Digital Aquastat

Easier to read. Other than that just aesthetics or style. 

Love TT's!

@ June 1, 2010 1:13 AM in TT Solo 110,,

I have installed many TT's and love them. Part of this is the self cleaning (stated from the factory) HX. Leaps and bounds from the aluminum HX's that need constant attention!!

tap tap

@ June 1, 2010 1:03 AM in Airtrol and Expansion Tank Maintenance

I can tap out a standard expansion tank to make sure the bladder is not busted or out of air but those old ones are much harder to tap out.
