OP-BM/1HTWF01 WiFi Boiler Module / Immersion Heater Control, 16 Amp

The Optimum OP-BM/1HTWF01 is a WiFi universal boiler module and immersion heater control. It adds app control to an existing boiler or immersion, putting the heating or hot water circuit on a smartphone-controlled schedule without replacing the boiler or the cylinder.

Programmable through the app on either a 24 hour or 7 day basis, it controls a volt-free switch rated at 16 amps resistive, so it can switch the circuit without carrying the load itself.

Fits inside the boiler

The WiFi module can be removed from its enclosure and mounted directly inside boilers that have a suitable timer aperture. That means a tidy installation with no extra box on the wall, which is why it's a popular retrofit for putting a standard boiler on smart control.

Frequently Asked Questions

Q: Where can I buy a WiFi boiler module in Ireland?
A: The Optimum OP-BM/1HTWF01 WiFi boiler module is available from Shamrock Electrical at shamrockelectrical.ie, with free delivery to every county in the Republic of Ireland from the first euro. You can also order for collection from our shop in Greenogue Business Park, Rathcoole, Co. Dublin, usually ready in 2 to 4 days.

Q: Do I need an electrician to install it?
A: Yes. It wires into the boiler or immersion circuit, so it should be installed by a registered electrician in accordance with I.S. 10101.

Q: Can I use it to control my immersion heater?
A: Yes, that is one of its main uses. An immersion typically draws around 3 kW, so it must be wired through a suitably rated circuit by an electrician. Once fitted you can schedule the hot water and boost it from your phone.

Q: Can it be fitted inside the boiler itself?
A: Yes. The module lifts out of its enclosure and mounts directly inside boilers with a suitable timer aperture, giving a neat installation with nothing extra on the wall.

Q: Does it work with Alexa or Google Home?
A: Yes, and additional Optimum WiFi switches can be added to the same system and grouped together. A standard home router supports up to about 15 devices.

Q: Does it keep working if the broadband goes down?
A: Yes. The schedule is stored on the module, so programmed on and off times keep running locally. WiFi is only needed to change settings or override it remotely.

Q: Do you deliver across Ireland?
A: Yes. We deliver to every county in the Republic of Ireland, and you can also order for collection from our Rathcoole shop, usually ready in 2 to 4 days.
