ᐅ Hydraulic Balancing Report

Hello,

does anyone have experience with hydraulic balancing? The reason I’m asking is that my heating technician prepared the attached report without consulting me first. Unfortunately, we installed a completely different type of flooring. That means, upstairs in the children’s rooms we have floating cork flooring, and in the hallway and bedroom, laminate. Only the bathroom actually has tiles.

Now I have the problem that in winter, the temperature upstairs never goes above 21°C (70°F), no matter how I adjust the heating.

Should the heating installer have used smaller pipe spacing, i.e., everywhere RA10?

I know remote diagnoses are always difficult, but I want to find out if there could already be a planning error in the hydraulic balancing.

Hello,

Be glad about that, at least errors are documented! ;-) The heat generator is probably a heat pump – right?

Why? A client must know what they want! Accordingly, the sizing of the heating surfaces and hydraulics is based on that.
Whether it is correct here, I rather doubt! Looking at the room heat loads, pipe circuit lengths (VA), I suspect a complete mess!
Is there a controlled ventilation system with or without heat recovery?

Winter? We haven’t had that yet! Rectifying deficiencies after the fact due to lacking correct planning, sizing, or execution usually leads to more or less significant problems, typically higher energy consumption! ;-)
The causes are diverse: incorrect heating load calculation, insufficient consideration of controlled ventilation (if present), incorrect heating surface sizing, faulty hydraulics, etc.......

For what reason? Uniform pipe circuit lengths in a building are, to me as an expert, one of the first indicators of a flawed system!

Not always. If the planning and sizing are already flawed, what good can come from it?
