Strengthen beam due to hole drilling?

[Mlwd]

I am going to install geothermal heating. I want to place the pump so that the collector hose needs to pass by a beam in the ceiling of the basement space where the installation will take place, see photo. Due to conditions outside, I cannot run the collector hose into the house on the other side of the beam. The installer wants the hoses to be run horizontally along the ceiling.

This means making holes through the beam. With insulation, we are talking about 75-80 mm Ø on the holes.

The beam measures 145 mm (height) x 125 mm (width).

The holes will be placed far to the left near the support in the wall.

How should I think about reinforcement?

Screw and glue solid angle brackets on either side of the lower edges? Angle support against the inside wall?

Hello
Is the insulation inside the wood really necessary?
Otherwise, it's just the floor on top of the beam, right?
It should be possible to drill holes without major issues if you stay in the middle of the beam since the beam needs to be more rigid than strong, given that it only handles floor loading.
Otherwise, screw glue in multiple layers and reinforce.

Hello
...

Thanks for the reply.

Yes, there's flooring on top. Joists across the beam and on these floor particles and so on...

According to the installer, insulation is needed there as well. I tend to agree, don't want to risk any condensation that might be absorbed by the wood, even if it's just a little.

Drilling in the middle doesn't seem like an option, the installer wanted to avoid bends as much as possible. The holes, therefore, need to be placed at the top of the beam.

Thanks for the response.

Yes, insulation is absolutely needed, otherwise there will be condensation and after a few decades the beam will have rotted away...
