Flush manifold cabinet Termojet No.01 (4-6 outlets, 435×575×110 mm)

Termojet No.01 recessed manifold cabinet — a built-in (cut-in) enclosure for concealed installation of an underfloor heating manifold with 4–6 outlets in a wall niche. Dimensions: 435×575×110 mm (width × height × depth). Made of galvanised steel, supplied with a decorative door. The solution for new construction and renovation where the manifold and associated valves must be concealed without losing access for maintenance.

Technical Specifications

Operating Principle

The cabinet is mounted in an opening cut into the wall and fixed on embedded anchors or screw fittings. Inside, the underfloor heating manifold with 4–6 outlets is placed together with the main supply connections and associated valves. The door conceals the unit from view while retaining access for flowmeter or thermal actuator adjustment at any time. A depth of 110 mm allows the manifold to be fitted with standard air vents and drain cocks as standard.

Where It Is Used

• New construction. The cabinet is built into the wall during construction or plastering — resulting in a neat, flush-mounted unit with no protrusions.
• Renovation. A niche of the required dimensions is cut into a brick or aerated concrete wall — the cabinet is inserted into the finished opening.
• Apartment or small house with 4–6 floor circuits. Dimensions of 435×575 mm accommodate the 5-outlet manifold with flowmeters or a similar 4–6 circuit manifold.
• Comparison with the surface-mounted version. For wall surface mounting without a niche, consider the external manifold cabinet No.01 of the same dimensions (435×600×125 mm).

Advantages of Termojet Cabinet No.01

• Built into the wall — the manifold unit is completely concealed and takes up no usable room space.
• Galvanised steel — corrosion resistance in the humid environment of a utility room.
• Decorative door — aesthetic appearance, harmonious integration into the interior.
• Size No.01 clearly defines compatibility with the manifold: 4–6 outlets — no need to select dimensions manually.
• Sufficient depth of 110 mm — accommodates the manifold with standard air vents and drain without trimming the valves.

How to Choose the Right Cabinet Size

The Termojet size system is linked to the number of manifold outlets:

• No.00 — 2–4 outlets (335×575×110 mm recessed)
• No.01 — 4–6 outlets (435×575×110 mm) — this cabinet
• No.02 — 6–8 outlets (565×575×110 mm)
• No.03 — 8–10 outlets (715×575×110 mm)
• No.04 — 10–12 outlets (795×575×110 mm)
• No.05 — 12–14 outlets (965×575×110 mm)
• No.06 — 14–16 outlets (1130×575×110 mm)

Underfloor Heating and Heat Pump

An underfloor heating system with a heat pump requires careful installation of all units — cabinet No.01 conceals the manifold and valves while maintaining convenient access for maintenance and adjustment when needed.

Frequently Asked Questions

Will a pump-mixing unit fit into cabinet No.01?
Cabinet No.01 with a depth of 110 mm is designed primarily for a manifold with valves. A pump-mixing unit has larger dimensions and is usually installed alongside the manifold — or requires a cabinet of greater depth. Verify the unit dimensions before installation.

Recessed or surface-mounted cabinet — which to choose?
Recessed (this one) — for installation in a wall niche: looks neat, takes up no room space, but requires cutting a niche. Surface-mounted (external cabinet No.01) is fixed to the wall without a niche — simpler to install, but the cabinet protrudes 125 mm from the wall surface.
