Yet Another EFM520 Install Thread!

I would love to have one of those!

Not really in my budget though.

That looks very similar to an "Extenda-a-hoe" boom mounted to the back of the truck.

Ingenious........

My vote would be for self propelled all wheel drive concrete burial
vault trailer with an extended boom.
The only issue is having enough 1/2" plywood for it to ride on to
avoid sinking in the ground with it.

Made some progress today. Cleared the boiler room, cleaned and painted the floor. I know it's unnecessary and will get messed up during the install. But I wanted to do it and I can touch it up after the install is done. I dry fitted the returns. Yes there is no bypass. Here's my logic. Feel free to shoot it full of holes. First I run the circulator pump between the oil boiler and the coal boiler 24/7. They are on opposite ends of the basement. It costs some $ to run the circulator and I'll burn a little more coal also as a result. I don't care. With water constantly flowing through the boiler I don't think there is a need for the bypass. Secondly It seems to me that with a bypass I'd be drawing return water up the bypass and into the supply being pumped away from the coal boiler. I don't want that. I want the return water to go through the coal boiler. Ok fire away! Damn sideways pics again! I'm going to retake them!

I don't think you need the bypass with the circulator running continuously.

If you're taking the photos with your iPhone hold the phone horizontally instead of vertically. The photos should post correctly then.

OK I'm a slow learner but I think I got it now!

I do the same, we are used to holding the iPhone vertically. Then we have to remember to go into "camera mode".

At least I think that's the reason.

I just realized while looking at the pic that I have the shut off valve and the purge drain in the wrong order.

Couldn't be more pleased with Supplyhouse.com. Prices are good and they got the stuff here is 24 hours. First shipment was free because it was over $99.00. Second one was $6.95. I think that's outstanding. I went to the 3 largest plumbing supply houses here locally and all had Chinese crap!

Oh!!! You're right!!!

Could you show a drawing of the circuit between the oil and coal boiler and the zone or zones?

With a constantly running pump you may already have your loop.

Would it be better to place your boiler return line off to one side or the other to allow

access to the hot water coil if needed in the future?

Lookin good CK! I like the paint job, but I bet StokerDon says it needs a stripe or two!

You can try this kind o' crap all day long but you won't get fired from this job!!! You are supposed to say - this is a test, there is something wrong in the pic (that I did on purpose....as a test.....), see if you can find it!

Barney - All of my zones come off of the supply side of the oil boiler. There's an indirect water heater, a water to air heat exchanger and two baseboard zones. There is 1/1/4" copper running from the coal boiler supply into the oil boiler return. Then the supply out of the oil boiler runs back into the return of the coal boiler. It's very simple but then so am I so it works for me. I won't be using the water coil. If I had a solid plate I would just eliminate it.

Actually Stokerdon was ready to start plumbing last Saturday after the boiler made it into the basement. He wasn't thinking paint at all. I needed to hit the brakes and think and plan a little bit. I should be ready to start real plumbing on Saturday this coming weekend.

Make sure you have enough Elbows. You don't want to have to substitute a Tee.

YUP!. Your system is "pump away" so you need a shutoff valve below the power purge valve going into the return.

What you have there will work. I see you put a Tee in the one return. If you put a Tee in the supply, you can always add a bypass later if things change.

Did you reduce the crossover pipe to 1" or is it just my bad eyes?
