In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Hi all I am hoping you can help. I will try to keep this brief.
We converted our home from oil to high-efficiency gas in April 2016. We have four heating zones. Three of them are Hydro air zones and one small zone over the garage is baseboard. I have nest thermostats on all four zones. For completeness we also have the gas line connected to an outdoor heated swimming pool as well as a gas log insert in one of the fireplaces that has been there since before we moved in 4 1/2 years ago.
This is our second heating season with the new system. It’s a navien nub 150. Our house is 4000 sf.
Last season our issue was that the baseboard zone never reached desired temperature. It just can’t do it. It used to be able to do it when we had oil but now it will not reach above 62°. The system just constantly cycles. We did have them put a Mitsubishi mini split unit in that room at the time of heating conversion. We did this because we wanted air conditioning in there since it is over a garage and is swamp in the summer. So I could have heat if I wanted to. Last year was not a huge issue since we had a mild winter and I only realized this lack of hitting desired temperature late in the season. That is where the kids play so I am not in there all the time.But I try not to use the Mitsubishi for heat because I am afraid that during the cold winter’s we will burst pipes feeding the baseboard. I realize I can just remove these but I am determined to figure out what the hell is wrong with the system.
This year including today our heat has gone out four times of the last 10 days. The error message is always the same. E 003 indicating an ignitor failure. Apparentlythey have replaced this twice and they have replaced the control panel inside the boiler is well. I am not sure what they are going to do today. Of note today I was successful in manually resetting the unit. Is currently producing heat although I don’t know for how long. It is literally 0° outside so I’m hopeful we fix this system.
My question for the group is do you think this could potentially be an electrical problem that keeps shorting something out inside the boiler? I ask this because on one of the days where we did not have heat my electric oven also did not work. When they came and fixed the heat the oven worked again. However they do not appear to be on the same circuit so if there is a connection it must be magical!
We pay a ridiculous amount in heat. For the month of mid October to mid December in New England we just use 280 servings. We only keep the temperature at 68 Max and down to 62 at night. There are no draft anywhere. We have had a significant amount of insulation work done including around windows and in the basement and in the attic. I just don’t get it. We are paying more for natural gas with all of this insulation work then we did with Order. Neighbors with homes of similar size use a 3rd to 50 percent less than what I use And they haven’t had all of the insulation work done .And all of their zones apparently work!
Do you think that the zone with the baseboard is the issue? If the zone is constantly calling for heat and is never satisfied I realize that is obviously definitely not efficient. But why would it not work? It used to work when we had oil and all of the other zones work currently. Could it be the water set temperature? Without really make that big of a difference? Is the fact that the boiler keeps breaking down somehow indicative of why that one zone would not work? Any help would be appreciated.
