Hot Water Baseboard Heat Not Warming the house

in THE MAIN WALL
I have a 954 sq. ft. house that we recently remodeled. I live in Colorado and it is mighty cold today. I just got the heat installed on Monday. I have a Navien NCB-210 Comb-boiler that is providing the hot water for this system. My water going through the Hot Water Baseboard is 160 degrees, but my thermostat won't move above 59 degrees and this system has been running since monday night. What do I need to do to get my house warmer without having to use space heaters?

    How do you know the water is 160˚F? If it's a gauge on the boiler, much of that water might not actually be leaving the boiler room.

    Can you post a photo of the boiler along with nearby piping, valves, and pumps?

    Well the boiler says supply temp and return temp. At one point I checked the return temp and it was 158. I am not at home currently, here are the pictures I was able to get sent to me. The pipes on the left are for the hot water baseboards which goes down to a taco recirculating pump and then to a honeywell zone valve I believe.

    A supply of 160˚F with a return of 158˚F clearly indicates a piping and/or pumping issue. Who installed this masterpiece? Do you have a piping diagram? How about a heat loss calculation?

    You didn't pay someone to install that, did you?

    I'd say, it had to be done by a drunken handiman, but I wouldn't want to be disrespectful of drunken handimen.

    LOL!!! at least they definitely used primer on the pvc vent pipe! I have no idea what is going on there.. I also like the yellow extension cord for the pump power. Classy!

    Call me crazy, but I think the washing machine hookup is one of the more creative things there....just don't bump it too hard.

    Seriously you need to measure temps out at the baseboards. And were the base board footages sized to run lower water temps.

    If you have a delta of two degrees there is some serious, piping, pumping issues. Are you sure the water is even leaving the boiler??

    Gordy...Follow the supply and return down, to what resembles a by-pass. That's their P/S. Circs in series through the boiler.

    Your problem could be a number of things. But assuming the circ pump, zone valves etc. are all working a common problem is an air lock especially on a new installation.

    Your right Paul....don't open the window whilst in operation either.

    LOL....You can't open it. It's a casement and hits the vent.

    So this is a DIY, right?
    I think your immediate problem is that you are air locked and you have not provided a means to purge the system.
    As noted above there are significant issues with the installation. Some present a serious safety concern. The venting by the window is one. The t&p valve location and restriction is another.
    I think you need some help making this safe for the occupants.

    By the looks of that mess,the installer should step back,put the tools down and let someone who knows what they are doing come in and rip it out and fix it,wow what a nightmare!!

    land7443.........Seriously, that installation is dangerous. You can't exhaust an appliance next to a window. The piping is completely wrong. The expansion tank will most likely rupture around the threads, positioned like that. Before that happens, it will probably pop and ping as the water expands into it.

    Apart from all the issues that have been mentioned, the Navien MUST be piped in primary/secondary as the manual shows. The way it's piped now is not p/s and is causing flow to short circuit out of the boiler and right back in.

    Sorry to see such a mess.I hope you know the installer and it was someone trying to help you out.Please tell me a heating company didnt do that.From what I see the only answer is to rip it all out.Navien sells a manifold that connects to the heating side and makes the install idiot proof,maybe look in to that.How is the boiler being fed and is there a backflow,i cant make it out.Call the guy back and get your money returned,that install is probably going to void all warranties on that unit.Act quick.

    I am far from an expert, but does a house that size really need that size boiler? 100k for 954 sq ft? I guess if it gets cold enough and the insulation is that poor? Just something that popped into my mind when I read this.

    No it should not but then a navien does not make that small of a unit.

    Kind a like I got a cheap price for this car with a 455 motor when I would pay more for a 1.8 litre even though it's all I need mentality.

    They make at least one unit small in that series?! Of course given the "quality" of the install I doubt much thought was put into a heat loss calculations. Haven't heard anything more from the OP, I wonder what they are thinking? Hopefully they can get this squared away.

    You probably could have used a 50 k boiler. Navien does not make one that small

    It's a combi boiler and you need a lot more btu's to heat domestic water instantaneously.

    As a homeowner who lurks here quite often, I was in a similar situation. Not nearly as bad as this but thanks to the real pros on here, they will help you. They will give you the straight skinny despite what your installer says. I am looking forward to seeing how all of this pans out.

    In reading the responses to this thread I find maybe we are a bit harsh myself included. While we are all geared in a way to be quick to criticize a less than stellar install we are here to help.

    Sometimes comments are to put forth the severity of a particular situation.

    I only say this because the OP has not returned to get advice, and who knows what is being done if anything. Probably due to humiliation as to what who ever installed this thought was an easy task.

    I guess what I'm trying to say is we should be more tactful about how we evaluate, or criticize that's all Ja.

    We never initially know if the installation was done by a homeowner, friend, or a Pro sometimes. I believe this was a DIY since no follow up has happend yet. Maybe due to a little humility.

    You're right Gordy. I reallized it too late. We need to be tactful. It's kinda like having a new mother uncovering the babies face, and the damn thing is horrifyingly ugly. You really shouldn't scream out, or faint, no matter how hard it is.
