OP-BM/1HTWF01 WiFi Boiler Module / Immersion Heater Control — 16 Amp
Add app control to an existing boiler or immersion The Optimum OP-BM/1HTWF01 is a WiFi universal boiler module and immersion heater control. It lets you put an existing 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.

PRICE INCLUDES VAT & FREE DELIVERY ACROSS IRELAND 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 across Ireland from our base in Rathcoole, Co. Dublin. Q: How much does the WiFi boiler module cost? A: It costs €113.52 including VAT, with free delivery across Ireland. 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 collect from our Rathcoole store. Supplied by Shamrock Electrical Supplies, Rathcoole, Dublin.
