IBC DC 20-125 Piping Diagram

I want to install a new high efficiency combi system, with 2 zones (one fin baseboard loop and one cast radiator loop). I chose this model which is oversized for my heating needs for the 3.2 DHW GPM. I have completely rebuilt this house from the studs on my own and want to finish the job with this system. Where could I locate a thorough piping diagram to insure a safe and effective installation?

Condensing Combi VS Condensing with Indirect Tank

Hey everyone,

Looking for some help on which way to go. I'll try to make a long story short and I'll be happy to answer any questions.

I have roughly 3000 sqft house that is heated by hydronic baseboards in three zones, one for each floor. Currently they are powered by an electric boiler and the cost is killing us. We had a couple $1600 bills over the winter. We live in British Columbia, west coast of Canada and electricity is very expensive here. So, I am looking to switch to natural gas. Speaking of location, our winters are considered mild, at our coldest we get down to about 28F/-2C. Maybe a bit lower in the last couple years

My questions is whether I should look at a combi condensing boiler or a condensing boiler with an indirect tank. I should mention the bottom floor of the house is a suite, so there is a tenant in there who I have no control over when/how they use their hot water. They have a washer and then just domestic taps, no dishwasher.

A contractor I am talking to right now is suggesting a Navien combi condensing unit, which after a short look online I am very skeptical of. All I see are nightmare stories from both homeowners and contractors on the units themselves and the support from the company.

Any insight and advice would be greatly appreciated!

Can I/should I change my header

Hello all. I have a Burnham IN5 with 360edr connected load. I have been replacing a few copper sections of main and replacing a riser. So I was thinking since I had the tools out; should I add the second riser out of the boiler. Would it make a difference. My idea was to add a union before the take off and try and make a drop header if possible. Or should I just leave it be? The current pipe size is 2 inches. Attached is my current set up. Thank you all.

Re: What's your favorite multi-tool? I mean that folding one you keep with you at all times at work.

Yes. We all agree on "the right tool for the right job" thing, and I'm on a 20-year CRUSADE to get my guys to stop using channel locks, but doing estimates and walk-throughs, it's handy to have something in my kit to open a control cover or strip a piece of wire to jump out a couple of terminals. Today I needed a file.

My Skeletool came up short.

Re: Hydronic Baseboard Return Tubing Expansion Noise

or consider adding outdoor reset to the system.

The noise you are experiencing is the rapid expansion/contraction of the pipe when it goes from 70F to 180F.

Outdoor reset controllers will modulate the water temp based upon demand and outside air temp and can help in quieting the system down.
It can also save you some fuel costs.

Re: Big Mouth air vent update

I should have Amazon stock shipped later next week. Unless @Phil53 wants to step up to the plate and handle my retail sales.

I'm handling all orders I have on my sheet here at work before I get to any Amazon stock though so if you want one sooner, best to call and get on the list.

>> then drops back down 28" into the next basement space<<
how does the condensate return from the bottom of this down 28"?</blockquote>

I'm thinking - it's probably parallel flow main from there and terminates at the end somewhere into a wet return...
