1.5 to 2 bar , but ours is lower than the house & we have 650 to 700 meters of pipe in the ground
That’s a lot of pipe for a new build but you do get much colder winters than us. We’ve only got 400m and an 8kw system but I do sometimes wonder if I should of pushed for 600m. Would of only been two extra hours with the digger
