@ May 12, 2013 9:55 PM in Hot water recirculation do they save money?So far I like the system I normally get hot water in about 5 to 15 seconds not sure that is good or bad the temp is around 90. The only annoying is at least once day I get a cold water sandwich and it takes at least 60 seconds for the unit to kick in, i am assuming the small storage tank would solve that as you mentioned. I have also heard people state that i could set preheat but that just bugs me to have the unit running during that that time especially if no one takes a shower at that time. What temp should the aquastat be set too? How much more money am I burning with this feature?

I have done some research on this topic and their seems that some people agree it does save money do the fact your not wasting water, other seem to think your wasting energy because the system is keep the water a certain temp. I got one installed and did not want it installed but their was confusing of the options that were presented. I have noticed that when I shut down the recirulation pump the water temp jumps up to 140 degree and then quickly goes back down to 120. With the pump on the water instant at 99 degrees and never jumps over 120. My DHW is a navien ch240 that is set to 120 for DHW. My concern is that I spending more money just to have instant hot water. I know it's better than heating 50 gallons..
I have also heard that these systems cause Corrosion-erosion within the copper pipes has anyone experience such an issue?
@ February 27, 2013 12:58 PM in DHW recirculating pump & Circulator Remote Bulb Aquastat,Hello
Sorry for the newbie question but what function does a Circulatory Remote Bulb Aquastat do with a with hot water recirculating pump? I have this gray box with a dial on it that is connected to my hot water pipe and I have no idea what it does.

One more question my system has how water recirculating pump does help or should I still turn on the preheat? I should mention that it has thermostatically controlled pump ( i think there is box that is connected to the pipe with a romex wires connected to it) and the high temp board is set to low temp and dwh is set to 140. I will be setting the dwh down to 120 I think this is the cause the issue. I have seen this issue start right after the high temp board was installed and I was told that dip switch 7 and 8 was for hot water, which as you know on the high temp boards switch 8 is high temp and low temp setting. I also learned that if you have high temp set then you must have remote installed to controlled dhw. If I turn on the preheat how much more enery will that use?
@ February 24, 2013 9:41 AM in Ch240 remote installThx for the advice great info I have not had a chance to get the connector or outside sensor. As for the heat loss calc I would assume yes but you never really know. The house is baseboard heat and their seems to be enough baseboard. As for the fumes I have one hardwire CO detector with three feet of the unit, a battery CO within 10 feet and a gas and CO detector within 20 feet none of them have gone off. Could a gas leak outside affect gas composition? I have had three leaks by the union joint before the meter, I hope that issue is finally resolved. To say the least it has been a real experience converting from oil to gas. I will try to take a few Pic today.
@ February 23, 2013 3:10 PM in Ch240 remote installSo the house is built in 1984 so I am assuming it has insulation in the walls, it does have insulation in the attic The house is 2200 sq feet two floors and two zones. I have converted from oil to gas my system was installed by a pro. It has been a real experience to say the least the union joint outside by the meter leaked three times. The unit does a great job and I am happy with it but on single digit days the system struggles a little bit. I can not put the system at the high temp setting because the dhw goes up to 160 navien stated that I need the remote installed if it is switched to high temp. Also I can smell exhaust or a little gas once in a while if I am standing in front of the unit like with in a foot.

What advantages does outdoor reset provide?
@ February 20, 2013 7:35 PM in Ch240 remote installWould the make wire be in the unit and do you know how long that wire is?
@ February 20, 2013 5:58 PM in Ch240 remote installHello
I was wondering if anyone could walk me through installing the remote. Sorry for the newbie question. I open the box that the remote came in I see that it has a female connecter, is there a wire in the combi that is a male connector? I saw the wiring diagram but not sure if I need to run a wire or if there is a wire already in the unit.

Once in a while or I should say at least once a day we do not get hot water and it takes like a good two minutes before any hot water. What could cause this issue?
@ February 2, 2013 5:29 PM in Navien 240Hello
Your both on the money the plumber came out and installed the high temp board. The weird this is that the system starts at 180 and after a few minutes it sets the water temp to 160 then 150. Just weird to me because I am use to the older systems where that water tempter does not change. I was also told today that with these new condensing systems I should just set the indoor temp and for get it. Instead of turning down the temp when I am off to work and turning it up when I get home.

Question about my heating system on really cold days single digit day it takes a very long time for the house to come up to temp. The supply is set to 180 and it does start at 180 but them it seems that the system turns down the system down to 160 even thou the house has not reached the desired indoor temp of 72. I am use to the old style of boilers where the system turns and the water is set to 180, so is it normal for a condensing boiler to be running for longer periods?
