The guy who quoted me the 24K outdoor unit and the 15K and 18K indoor units pointed me to Daiken's installation pdf: Multi-Zone Combination Table Install the indoor unit according to the table below, which shows the relationship between the class of indoor unit and the corresponding port. The...

I did not ask for that, and not a single one said anything about doing a manual J.

I have no idea if this helps in any way. I looked at my natural gas usage for heating the house and it averages 1000 therms per year at worse. Very roughly estimating my boiler efficiency at 90% at best. So I needed 90,000K BTUs/year at worse to heat my house. I followed instructions from green...

I'm in Northeast Massachusetts. We have gotten some estimates on a mini-split system with 2 heads. This is not for the whole house, it is just what we can afford to do at this time, and to tackle the 2 worst areas in the house during the summer. Heating during the winter would be a positive, but...

I do not know about the flu analyzer. I did exactly what you suggested. Thanks.

I have a noisy Grundfos UPS26-99FC pump. Sort of a clunky sound when running. A few months ago it had locked up, but switching the pump to high speed got it running again. But, then the noise started increasing. So I ordered a replacement cartridge from supplyhouse. I noticed about 3/32" play in...

There was a weird white coating on the bathroom window about 5' above the exhaust and on a first floor window about 15' away horizontally.I've tried a bunch of window cleaners and chemicals and it does not remove it. I can get some off using a single sided razor blade, but even that is very...

Forgot the picture

The original installer piped the intake and exhaust from my Navien NHB-150 incorrectly according to a new plumber we called out for maintenance. The town inspected and OK'd the installation. I've attached a picture of the outside piping. The intake comes out of the house on the right of the...

Thanks that makes sense. A tankless has the domestic water flowing thru the heat exchanger whenever someone turns on the hot faucet. Simple, but I could not understand it on my own. Thanks again.

I have gotten 2 different opinions on flushing my Navien NHB-150 boiler during annual service. The installer, who no longer services or installs boilers, would flush the system during maintenance. A new plumber who came out says it is not necessary to flush. I looked at the Navien website...

Thanks, I did not have that manual.

I did what an old plumber taught me. Took the metal end of a screwdriver and placed it against the Taco pump, the other end went into my ear. It sounded like a motor/gear moving smooth. I then did the same with the Grundfos, that has a consistent rattle noise, but that pump has been working on L...

I did not see any codes after I came home and turned it back on. My wife first saw what she described as red gobbledygook flashing, and then seeing the E001 code before she turned things off.
