Underfloor heating only performs as well as the manifold and controls behind it. A well-balanced stainless steel manifold gets hot water where it needs to go — but it's the thermostat, wiring centre and actuators that decide when and how much. Engo Controls gives UK installers a genuinely flexible way to control a UFH system, whether that's a full smart wired setup, a wireless ZigBee install with no chased-in cabling, a simple hubless wired system, or an electric-mat retrofit in a single room.
This guide breaks down four affordable ways to pair Engo Controls thermostats with a stainless steel underfloor heating manifold, plus the wiring centres, actuators, gateways and installation accessories you'll need to finish the job properly.
Four Ways to Control Your Underfloor Heating
Every Engo Controls UFH setup starts with the same manifold — the difference is entirely in how the thermostats talk to the wiring centre. Here's how the four approaches compare before we go zone-by-zone.
1. Wired UFH (Smart Hub)
230V wired Engo ONE thermostats connect to an ECB8-230 wiring centre and E30NC-230 actuators, with an Egate-Pro-UK gateway added for full app and voice control. The most fully-featured option for new builds with first-fix cabling in place.
2. Wireless UFH (ZigBee)
The same Engo ONE thermostats communicate over ZigBee 3.0 to an ECB62-ZB wireless control box — no core cabling between rooms and the manifold cupboard. Ideal for retrofits, extensions and rooms where chasing walls isn't an option.
3. Wired Hubless UFH
EONE-16W or EONE-16B thermostats wire directly to an ECB8-230 wiring centre, or drive electric mats directly via their own built-in 16(2)A relay — no separate ZigBee gateway or control box needed for app control.
4. Electric UFH
For tiled rooms without wet pipework, an EONE-16 electric thermostat pairs with 150W/m² peel-and-stick heating mats for a fast, low-disruption single-room retrofit.
Why the Manifold and the Controls Have to Be Chosen Together
A stainless steel manifold with 2 to 12 ports sets how many independent zones your system can run — but each port needs an actuator, and each actuator needs a signal from a thermostat via a wiring centre. Undersizing the wiring centre for the manifold you've fitted is one of the most common UFH snagging issues on site.
Rule of thumb: match your wiring centre zone count to your manifold port count, and choose wired, wireless or hubless Engo controls based on how much first-fix cabling is realistically achievable in that property.
Engo Controls UFH Systems Compared
| System | Thermostat | Wiring Centre | Actuator | Gateway | Best For |
|---|---|---|---|---|---|
| Wired (Smart Hub) | EONE-230W / E40-230W | ECB8-230 | E30NC-230 | Egate-Pro-UK | New builds, full app control |
| Wireless (ZigBee) | EONE-230W / E40-230W / EONE-BATW | ECB62-ZB | E30NC-230 | Egate-Pro-UK | Retrofits, no cable runs |
| Wired Hubless | EONE-16W / EONE-16B | ECB8-230 | E30NC-230 | None required | Simple, budget installs |
| Electric | EONE-16 | N/A — direct to mat | N/A | None required | Single tiled rooms |
Wired UFH: Engo ONE Thermostats, ECB8-230 Wiring Centre & Egate-Pro-UK Gateway
The wired smart setup is the most complete Engo Controls UFH system. The EONE-230W (or the more compact E40-230W) mounts flush on the wall and connects directly to the ECB8-230 wiring centre, which in turn drives an E30NC-230 actuator on each manifold port. Add the Egate-Pro-UK gateway and every zone gets app scheduling, temperature history and Alexa or Google Assistant voice control — all while continuing to work locally if the internet drops.

Wireless UFH: Same Engo ONE Thermostats, ECB62-ZB Control Box
Where cabling between rooms and the manifold cupboard isn't practical — a barn conversion, an extension, or a retrofit into an existing screed floor — the wireless system swaps the ECB8-230 for the ECB62-ZB. It's the same EONE-230W, E40-230W and EONE-BATW thermostats, communicating over ZigBee 3.0 instead of a physical wire, with actuators still switched locally at the manifold.
Engo Controls
ECB62-ZB ZigBee Smart Control Box, 6 Wireless + 2 Wired

Wired UFH Hubless: EONE-16W & EONE-16B with ECB8-230
The EONE-16 series is Engo's Wi-Fi-enabled wired thermostat range — available in white (EONE-16W) or black (EONE-16B) — with a built-in 16(2)A relay that can drive underfloor heating loads or electric heating mats directly, or signal the ECB8-230 wiring centre for a wet UFH manifold. Because the Wi-Fi module is built into the thermostat itself, there's no separate ZigBee gateway or ECB62-ZB control box needed for app control — a straightforward, self-contained option for wired zone-by-zone control.

Frequently Asked Questions
Do I need the Egate-Pro-UK gateway for wired or wireless Engo UFH control?
No. The ECB8-230 (wired) and ECB62-ZB (wireless) wiring centres will both run a full underfloor heating system on their own. The Egate-Pro-UK gateway is only needed if you want ENGO Smart app scheduling, remote access, temperature history or Alexa/Google voice control.
Can I mix wired and battery thermostats on the same system?
Yes. The EONE-BATW battery thermostat and the wired EONE-230W or E40-230W can sit on the same ECB62-ZB wireless control box, so you can use battery stats in rooms without a supply cable and wired stats elsewhere.
What's the difference between the wired hubless system and the smart wired system?
Both use the ECB8-230 wiring centre and E30NC-230 actuators. The smart system adds ZigBee-capable EONE-230W or E40-230W thermostats plus the Egate-Pro-UK gateway for app control. The hubless system uses the EONE-16W/EONE-16B thermostats, which have Wi-Fi and a 16(2)A relay built directly into the unit — so app control is available without adding a separate ZigBee gateway or control box.
How many ports do I need on my underfloor heating manifold?
One port per heating zone/loop, matched to your wiring centre's zone capacity. The stainless steel manifold above is available from 2 to 12 ports, so it's worth confirming the room count and loop lengths before ordering.
