5 year-old Carrier heat pump, two stage. Had a maintenance check and the tech says I need a new TXV. Do you agree?
Suction pressure 93.3psi
Superheat 15.7°
Vapor Saturation 28°

Indoor temp was 68. Don't know indoor humidity for sure, but outdoor humidity was low that day - probably about 40%.
My system is only a few years old, and it doesn't seem to perform as well as it did a few years ago. I have had it serviced by the installer every year. Recently I had the installer out, and they...
Just to close this out, turns out to have been a bad control board. Got a new one and has been working fine since. As always, thanks for all the helpful feedback.
So, system seemed to work fine overnight, was keeping house at set point most of the day today, and then suddenly shut off again. I guess if there is a leak they would be able to figure it out...
Yeah, I am concerned there might be a very slow leak somewhere. How would you find a slow leak?
We had a high velocity heat pump system installed in our house last September. Outdoor unit is Carrier, indoor is Unico. The system is 4 ton, 2-stage, with variable speed blower. House is 2400...
Ordinarily the additive would void the warranty. I wonder what the long terms effects are going to be.
No, not even close to 70% of the time at any temp we have had so far.
I don't think the heat pump has any problem keeping up down to low temps. It is just that the upstairs gets a fair amount warmer than the downstairs due to duct set up, which is the opposite of what...
PHM: When you refer to the number of outlets for the length of the duct runs, do you mean to say that a longer duct needs more outlets, or a longer run needs less? For what its worth, the large...

I had a high velocity heat pump installed this fall in our older house without preexisting ductwork. Haven't had much chance to use the A/C but we have been using the heat pump when temps are in the...

I have heard about an industry-wide problem with thermal expansion valves failing, supposedly due to a chemical used in scroll compressors of recent manufacture. I am wondering if this is a defect...
Okay, pecmsg, so how would you do it?
Unfortunately that would not work well for me because the constant circulation keeps the temp even in the back of the house. When we do not have constant circulation, the back bedrooms get a bit too...
With respect to the dual fuel thermostat, I think what my installer said was that if he connects the circulator to the thermostat it will turn the circulator on and off on demand from the thermostat,...
Don't worry, not doing it myself. But, surprisingly, even Buderus doesn't seem to have a good answer to this, so figured I would get some pro opinions.
I have just one zone and convectors.
...
So, it seems there is no great way to automatically coordinate the Buderus with a heat pump. Apparently I cannot get a thermostat that switches from heat pump to oil at a given temperature absent...
I can tell there were some strong opinions on this one. :whistle:
Decided to go with the Carrier, primarily because they advertise a slightly quieter unit.
The quote says 10 years on both, so if nothing else I can hold the installer to it.
10 year for both.
Basically comes down to whether one is better, or quieter, than the other.
Help me choose - Lennox XP-16-048 or Carrier 25HCB648? Same installer, Unico variable speed air handler, price is virtually the same. Installer does more Carrier than Lennox, but does both. ...
I am installing a high velocity AC system in my house this fall. I have oil heat (Buderus w/ logamatic, room sensor, and outdoor reset) and I am thinking about going with a heat pump so that I can...
The conventional estimates I received would only utilize one return, at the top of the stairs on the second floor, same as the HV system. That is why I am concerned about performance. I don't think...
I think the HV guys would say that operating costs would be about the same, since the unit doesn't have to work as hard to reach an even temp, but not sure I believe it. I would really be interested...
Planning to install a/c in my stone 1940's house. Have been using window units for a few years, which work well and cost me next to nothing in operating costs, but for a lot of reasons we would...
so, just to clarify what I did to get constant circulation, the Buderus system always runs on constant circulation when in "day" mode. The only time it does not run on constant circulation is in...
Steve - I use constant circulation because my daughter's room over the garage gets cold, and leaving it on constant circulation helps keep the temp even throughout the house. That is something I...
I bought a Buderus oil boiler last year with logamatic control and room sensor. It has taken some work to get it dialed-in just right for my home. For example, I had to set it to constant...
The odor is right near the boiler (not the tank). No odor when it is not running. It does seem to go away after it has been running for a few minutes.
Hi all,
This is our second year with our Buderus 115/4 section boiler, with Beckett NX burner. It has taken a while to get the programming/settings right, but I finaly feel like I am getting...
Got a Buderus 115 with logamatic control, room sensor, and outdoor reset a few months ago. I have noticed recently that the actual indoor temp is a fair amount higher that the setting on the room...
Gravity, I don't know what any of that means ("journeyman techs, member of ACCA, combustion certified"), but that is the kind of thing I am looking for. Thanks.
Look, I don't need a new boiler. I am just looking for a new oil company. I don't need or necessarily want the cheapest, it is just that mine is consistently $.30 per gallon more than the...
no gas on my street. would cost $16,000 to extend the gas main.
I am shopping aorund for a new heating oil company, as my old one is getting to be just too expensive, even though I like them a lot. Other than searching for reviews of various companies online,...
Ok, here's the info from the printed ticket. Let me know what you think.
T stack 363.7
Co2. *11.35
Eff 86.5
Ex air 36.5
Oxygen 5.8
Co. 15 ppm
Co airfr 21 ppm
Inh2o draft .0044
Sure, will do it later tonight. Keep in mind, these are from after he made adjustments.
Thanks, guys. I think the "not enough air" comment was probably dead on, as the guy who came out said I definitely needed a regulator.
I do have a copy of the analyzer results.
You may be right about the set up -- they apparently did not do any testing at the time they turned it on (that's the think with the sensor they stick in the boiler and chimney, right?). I had them...
p.s. - the sludge was very "oily" feeling.
As many of you know, I had a Buderus oil boiler installed a couple weeks ago. Yesterday, I noticed a lot of blackish-green, oozy sludge dripping from the smoke pipe at the joint where it takes a...
R Mannino, according to the manual, in the "RMSETBACK" mode, which only works with the room sensor installed, the circulator shuts off during night mode unless the room temp drops below the set temp,...
OK, sounds like primary/secondary is not a big concern with the Buderus, and probably not something I can make them change now, at least not without paying for it. (Does Buderus say anything about...
Ok, so I guess I don't really understand what primary secondary piping is. Can someone give me a simple explanation? How would that be different than what I have?
As for the circulator running,...
if i did this right, these should be pics of my new installation.

Yeah, I think that is exactly what happens -- it is getting rid of excess heat into the house, which is fine when it is cold out, but not so great when warmer. It may be mostly a matter of getting...
