How To Activate The Boiler Room In Blue Prince
Restore power to other facilities via the Boiler Room in Blue Prince.
Are you wondering about how to activate the Boiler Room in Blue Prince? Several rooms in the game have their own unique perks and effects. The Boiler Room, however, is all about functionality. Once it's working, you can restore power to other areas. In some cases, this could even lead to new discoveries.
How to activate the Boiler Room in Blue Prince
When you first draft the Boiler Room, you'll notice several objects and machinery:
- There's a central control panel at the top.
- There are three green pumps--two in the lower section and one in the upper section.
- A couple of red tubes down below can also be rotated.
- You'll notice two switches along the pipes as well.
The first thing you need to do if you want to activate the Boiler Room in Blue Prince is to make sure that all three green tanks are active--i.e. click on their respective valves so that the meter is in the green.
Solving the Boiler Room Puzzle: Lower section
Next, head down to the lower section and do the following:
- The first red tube--i.e. the one near a green tank--must connect to the longer system of pipes.
- The second red tube--i.e. the T-shaped contraption--must be linked to the initial pipe, the pipe leading to the central machinery, and the pipe leading to the fusebox in the corner.
- There's a small switch next to the other vertical pipe, so make sure it's flicked upward.

Solving the Boiler Room Puzzle: Upper section
For the upper section, if the switch is flicked to the right, then it'll open the adjacent doorway. Don't bother with that for now. Instead, flick the switch to the left so that steam is funneled to the machine in the center.

Activating the Boiler Room and connecting to other facilities
All three pipes should be funneling steam into the central machinery. You should then see that the whole panel in the center is lit up. Press the "Activate" button to power up the Boiler Room.
Note: The Boiler Room needs to be reactivated every run using the aforementioned steps. Once you've memorized what to do, you shouldn't have issues moving forward.
Another thing you'll notice is that there's a slider on the panel and it can be moved to the left, middle, or right. These directions pertain to the pathways/doorways in the Boiler Room. Essentially, you can power up facilities via connections made by ventilation shafts and ducts which you'll see on the ceiling. There are, however, a few caveats:
- Ventilation shafts and ducts can only appear in gear-type rooms (i.e. those with a small gear icon on the portrait) or red rooms.
- Gear-type rooms include Security, Workshop, Pump Room, and others.
- Red rooms include the Dark Room, Archives, Gymnasium, and others.
- Even if a facility that you want to power up isn't adjacent to the Boiler Room, you can still funnel power to it as long as you have an unbroken connection of gear-type or red rooms leading to that area.
- If you place others, such as green rooms, bedrooms, and the like, then the connection would be broken as the ducts/shafts won't appear.

What else can you do when you restore power in the Boiler Room?
Here are a few things that you can do once you've activated the Boiler Room in Blue Prince.
- The Boiler Room will remain active for that day even if you make changes to the switches and tubes positioning.
- If you can connect power to the Laboratory, you can complete the Laboratory Puzzle.
- This also works for the Garage, which then unlocks the Garage Door/West Gate Path. However, it's actually a lot easier to just draft a Utility Closet so you can flick the switch in the fusebox.
- You can draft a Pool, which then adds the Pump Room as an option. If you can power up the Pump Room, you can make use of the reserve tank. This allows you to fully drain the Reservoir or sail on the boat.
- Moreover, if you check the lower section of the Boiler Room, you should see a red control box in the corner. You can link the T-shaped red tube so that it lights up. This will unlock Red Rooms outside the manor. If you keep the red tube in this position, the Red Rooms will remain unlocked even on days when you don't access the Boiler Room.
Is there another way to restore power to facilities?
There's also another room that can power up facilities in the manor. It's none other than the Aquarium. However, you need to obtain an Upgrade Disk for it, and then you have to select the Electric Eel upgrade. This causes the Aquarium to act like a powered-up Boiler Room, though you still need to build a connecting path of shafts/ducts to the target facility.
