My latest install

Aaron_in_Maine

This my latest install. And the old steel it replaced.

Actually I will the guys wife runs a little in home day care so they keep track of fuel usage. I will have numbers next summer. I am curious as well I used the hydro level outdoor reset and wired the circulator to that instead of the ZVC. I want to see if holding off the pump until 120 degrees makes a difference in how clean the boiler is.

I'd say 30-40 % reduction in oil consumption.

Robert O'Brien

More like it with that combo, fire it at 85% of max and see what the stack temp is!

Robert O'Brien

Bet it's higher,most widely spaced pins and sections of any oil boiler. Easy to service and uses fuel, an oil man's dream

Looks like a nice install Aaron. This is no offense against your workmanship but one the things that pisses me off with Pro-Press is that if you don't have a way of holding the pipes in place during pressing you can't keep them plumb and level.

Aaron_in_Maine

Yeah the pro press tweak gets my OCD going every once and a while. I switched back to tees instead of premade welded headers because there is always that one branch that was just a little off.

Megapress is even worse for deflection. Whenever possible, I strap the pipes in place before pressing.

Simply elegant!!!

Looks great Aaron. Anything is an improvement over that Trianco that was in there. I still like to solder just for that reason, but we have had long posts on that subject. Excellent job

Looks good nice and simple.

I do have a question though isn't it better to run a separate pump for the DHW then through a zone valve?

Robert O'Brien

With priority,what's the difference?

Looks great Aaron! Down here in MA we're hiring installers/technicians with experience. Would be nice to have you! Is there an outdoor module connected to the hydrostat?

njtommy

There isn't, aslong as the flow rates are correct. I think I remember reading Taco not recommending them for use with Indirect storage.I tryed looking it up this morning and couldn't find it.

Aaron_in_Maine

Marz, yes I used the hydrostat out door reset tied right into the aquastat. Njtommy, I have the indirect set on priority I have done a few of these setups and they work well. I wouldn't be surprised to see them wanting a pump for the indirect. The heat flo indirect is piped in 1 inch on the heat side. The 3 section boiler ran one cycle to heat the indirect from stone cold and then shut off just as the indirect was satisfied. My supplier shakes his head every time I order saying I should use a 4 section because of the indirect. He only keeps one 3 section in stock for me everybody else buys a 4 section for this setup. I always say I have not had a problem. I set the indirect to priority, set the temp to 140, put a mixing valve on the tank and mix to 120.

Robert O'Brien

Zone Sentry ZV's add the equivalent restriction of 8' of straight pipe. Nothing even worth discussing. No one thinks twice about a conventional gas HWH with an input of 40K but a 65K boiler/indirect combo won't produce?

njtommy

null
Nope no you can't.

4Johnpipe

We use zone valves all the time for indirect as long as the system pump can provide the proper flow. i usually use 1" ZV for that zone.

njtommy

I've seen it a hundred times. Maybe this is why I was thinking it. I don't know, but I always run my tanks up in the 140s and mix down any way.
