I had originally planned on having the pumps at the boiler until the guy I get my stuff from suggested that I shouldn't because of heat issues with the Alpha pumps. Makes more sense to me for them to be at the boiler too.
I just have concerns with regards to sizing for the pumps. As wreckit87 mentioned, the 100 ft run is pushing the max for the Alpha pumps. Is it possible to put two pumps in the 100 foot run ? Say one at the boiler and one in the house ?

Plumbing / Re: Copper VS PEX

My place is 3000 sq ft with DHW and that's it.
So, going from the LogStor to 1" PEX and then to 1" copper like I originally planned wouldn't make much sense ?
Maybe best to just byte the bullet and go right from the LogStor to copper ?
I was trying to avoid the cost of the copper for the long run along the ceiling from the wall where the LogStor comes in to the furnace. But, I guess if I loose to much heat and have to replace later it just costs more in the long run ?

Plumbing / Copper VS PEX
« on: September 11, 2018, 07:28:29 AM »
I am installing a new Polar G2. I have LogStor 1" going from the owb to the basement. Once inside should I continue with 1" PEX or switch to 1" copper ?
I am told that most installations these days are done with PEX but all the pictures I see of installations of systems by users of this forum seem to be copper. I had planned on doing PEX once inside from the LogStor until I got near the furnace, about 12 ft, then turn to copper for the run to the exchangers and then back to PEX for the returns at the point I switched to copper for the feeds. Then, it was suggested that I just run PEX for all of it. Any suggestions would be great as I am new to this and want to try and make as few mistakes as possible...

Thanks for the reply wreckit87...in the house is fairly simple. I will come through the wall and go up about 8 ft. Then across about 12 ft to the furnace and a 18"x18" water to air exchanger. From there across about 8ft to a 30 plate exchanger for DHW then back out to the boiler.
I was told about the heat issue with the ECM circulators from the somewhat local guy I have been getting my supplies from. I am new to this so, I'm really not sure what I should be using. I just don't want to be using a lot of power to operate these pumps year round. That is why I was looking at the ECM circulators. I also don't want to be running into circulation issues with under powered units.

Hi Everyone
I am doing the install of my Polar G2 boiler. I'm trying to figure out what pumps to use and where they should be located. I was looking at the Grundfos Alpha 1 pumps.
I have two runs from the boiler both using LogStor 1" pipe. The house run is about 100 ft and slightly downhill to the basement. I thought it best to install the pump in the basement for this run ?
The second run is about 50 ft to my garage and is uphill I would think about 5 ft by the time it gets into the garage. I plan on putting a ceiling heater in there so it would be another 12 ft to the ceiling. I understand that the ECM pumps can't be mounted in the back of the OWB because of temperature issues...I don't know. If that is true, what options do I have for the garage run ? I would like to have energy efficient pumps on both runs if possible.
Thanks
Dave
