greenwood 100 install

[lizard]

I am installing a gw 100 right now. The supplier sold me 1" pex pipe for underground, then I ran 1" copper inside to dhw and infoor heat. I am being told the 1" is only good gor 71, 000 btus. Will I be ok.

I am also wondering if I should pipe as a open or presurized system.

Any help would be great, thank you.

Pex size depends on how many gallons per minute you need to move. This is determined by your heating load not what the supplier tells you.

Do you know what the heat loss of your house is?

Also how far is it from boiler to load? Is the pipe already buried? Who makes the pipe?

I do not know the heat loss. I am heating my basement floor infloor heat sq ft 2000.

I have already buried my pex it is 1" insulated ina plastic tube. The pex runs 65' to house and then switches to 1" copper for another 45' to 20 plate heat exchanger for dhw and lopped in to infloor heat.
