Re: Heat loss calculations. who does em?
If you do the work for the contractor, they never learn and will become to expect your free service all the time and quickly. How do you expect to do 20-30 a week someday?
You will burn out and and only anger your customer

Re: What is your longest running Combi Boiler without ever needing Service - excluding maintenance.
2006 Buderus GB142/45 Combi still running 4-Zone. Plenty of service calls, and replaced parts, now getting harder to find electrical components, but still working albeit, my fins in the HX are showing their age.
Will need to replace soon.😒

Re: BTU kW Sizing - I am pretty sure this is a stupid question but you decide!
@hot_rod I actually am not sure how warm the floor itself gets. I would have to measure to be sure. Certainly not hot, but comfortably warm.
I have 200 amp service, so I should have enough. I do have a ducted system as well. I generally only use it for AC, but it does have a heat strip in it in the event that I want to use it for heat.

Re: AO smith ECC code
Ditch the HP WH… junk.
Tankless gas would be my recommendation.
Electric tank HTP Everlast section option.
If doing Electric tankless you will need A LOT of power. 200 amp min service.
Very large wire 6 or 8 ga wire and 4-6 spaces in the panel.

Re: Floor Closet Flange Toilet
We stopped using Fluidmaster when the company owner passed and manufacturing was moved to Mexico. In NYC, 3/8 copper tubing is required for a toilet and hose is not permitted. The Mexican plastic Fluidmaster tubing nuts began cracking in half and leaking water below the valve.
We had a full time job of replacing them with brass ones. Couldn't keep up with them. Every week we'dget two or three.
Around that time, Fluidmaster introduced a model with a brass stem and nut, but the damage was done.
We've replaced them all with American Korkys.
Re: Rinnai E110CRP Error : E 02
If the gas pressure drops, that means the gas valve opened. The issue is not likely to be the gas valve.
Maybe when you re-assembled, the ignitor or flame sensor moved and shorting to somewhere.

Re: Should I stick with tankless coil?
not me,,i have a coil and it works great,i just turn off the boiler with a switch so it only runs when we need hot water,,takes about 5 minutes once the boiler is up to temp,, i have all the hot water i need for a shower,,also i clean the coil every couple of years,thats makes a difference,,everyone that bashes a domestic coil don't know what there talking about,you just have to know how to use it

Re: Should I stick with tankless coil?
Having said that if you are in an area like me where the boiler runs 6 months a year a coil is actually pretty efficient since if timed properly your hot water needs are "free" while boiler is making radiator steam. In 6 off months of non heating a coil is more wasteful but a payback on ROI for a standalone will be years out if like my case. So I stuck with the coil. I use approx $20-25 worth of natural gas/month in summer months including cook stove and boiler coil, so a standalone does not make economic sense for me, a wall hung will never pay back. Even a storage tank will be slow on ROI. Another downside of coil is if/when they fail later in the boilers life they can be impossible to remove without snapping the bolts or causing other issues. My last one went 23 year which surprised me, it was very crusty when removed from the boiler though!
