I recall reading somewhere that you don't want too much flow through the loops to get good heat transfer. I think you only want about 2-3 gpm per loop. Any faster than that and you will short cycle the heater. So the Taco 013's flow rate of 34gpm worked out about right for my 5 loops (includes...

Mel, I did the LED rope light retrofit in a 4' x 4' double sided fixture about 8 years ago. But used the warm white bulbs that I was never really happy with. So this past fall I took out the rope lights and installed (4) 2' tube light fixtures as shown in the pics...While it works great and...

Last weekend it warmed up and was the busiest weekend we've had in the last 2 years. I had a TF hydrominder fail causing me to scramble to get it fixed while cars were 3-4 deep waiting on the bays...Definitely raises the BP! Today we've had snow, rain, and now freezing rain! So a good day to go...

I didn't use any kind of calculator... Coming up with something that worked as efficiently as possible was through trial and error. My system is energized off the auxiliary output on the weepmiser @ 32°. Basically energizing a 20a 120v relay that powers the loop circulator, the (2) circulators...

I think you won't get answers as to one size fits all. You don't want to run a non condensing boiler at the same temperature as you would a condensing boiler. Non Condensing has to be ran at above 140° (I believe) to keep it from condensing and self destructing with highly acidic condensate! I...

LOL...They actually aren't lying! In the specs, they boast the "Maximum" flows. Its just the moon and stars need aligned before you can get those maximum flows! That's why when going to a demand heater, its extremely important to do your homework to find out how much capacity and Delta Rise you...

Most demands that I know of limit flow to maintain the setpoint outlet temperature. If you look at the Delta Curve (Difference in inlet and outlet temperature) in the manual, the higher the Delta, the lower the GPM flow is to maintain the setpoint temperature. That's how my Takagi works and...

What I posted was actual. There is a readout on the front that toggles between inlet temperature, outlet temperature, and flow in GPM...Mine flows at 6.7 gpm at 40psi inlet pressure. If you look at the graphs in the Takagi instruction manual, the "Boasted" Max GPM stated is rated and based off...

Since there isn't a dedicated Hydrominder Routine Maintenance Thread on here, I thought I would start one. I have a few questions of my own that come to mind for discussion. Anything else that comes to mind, please add. I think this is the biggest. Do you remove the small washer strainer and...

How many GPM and at what temperature? My Takagi 199k Floor Demand Heater puts out 6.7 gpm @ 105°...That's 402 GPH....So yea, they can output a lot. Just keep an eye on the tiny inlet filter if it has one. It will plug easily if you don't have a larger pre-filter.

Thanks IB for the link! More reasons to install the highest Energy Efficient system as possible and let it run below 32°. Don't take chances! My complete system only draws 600w @ 120v and sips NG, so the smallest of gen's will keep it going easily in case of extended power outages. It never...

Not for me! When we bought the wash over 8 years ago, it came with an old Hamilton bill acceptor and party hopper! We thought we had bought a goldmine when the next day the hopper was empty! But only had $9 in the acceptor! LOL...Luckily the wash came with hidden cameras and saw what the guy was...

IB, I had heard the same thing. Plus the website is still up. So confused as to what's going on. Maybe someone will chime in to explain further? I would think that would be a lucrative business to continue?

Maybe so. I was going to send him a head to compare against Vilco, but was not going to send one when I wasn't getting any response.

I tried calling and emailing Dynajet about a month ago...Even left a voice mail and no one ever returned my call or email....Maybe they aren't in business any more? I put a Vilco head in service about a month ago and it is doing fine....

Seems as though when ever my wife and I get away, something breaks down at the wash! It can go months and months and not even a single glitch. But as soon as we leave the driveway, it rears its ugly head! It knows!

That was back in 2015 in February....Here were the stats for the month. 21 days Max. temp was below 32° 29 days Min. temp was below 32° 19 days Min. Temp was below 15° 7 days Min. temp was below zero Coldest night was -15° It was very cold for a long time. My pit grates are 16" wide 1/4" plate...

Ok...I'll play along! As long as it doesn't get rid of my "Thread Killer" status!

I have PS and TF on the same foam gun. PS uses a flojet @ 60 psi and the TF uses a procon pump at 80psi...Neither foam as good as what was in that video. I have new home made foamers I want to try that I know will be better than what's in there now. I wonder how much pressure he's running and...

My truck bay pit froze 5-6 years ago solid enough I couldn't break through the ice. I dumped a bunch of salt on top and poured hot water on till it broke through. I don't think it would have been good if it had froze down into the drain! From then on when I close any of the bays down, I put a 2...
