WiFi Heater Install — When to Go Permanent, and When a Plug-In Is Fine

WiFi Heater Install — When to Go Permanent, and When a Plug-In Is Fine

WiFi-controlled panel heaters, convection heaters and oil-column heaters have taken over the room-heating market. Redwood, Rinnai, Goldair, Devola, Bromic. The question that comes up on nearly every install: does it need to be wall-mounted and permanently wired, or is a plug-in setup good enough?

What the rules say about permanent vs plug-in

Two things drive the decision: clearance distances and the manufacturer's instructions.

Clearance distances are non-negotiable. Every panel and convection heater has minimum distances it has to be kept from curtains, furniture, ceilings, the floor, and combustible materials.

If you can hit those clearances with a plug-in unit, plug-in is fine. If the only viable heater position doesn't have a socket nearby, you've got two choices: add a new permanent socket in the right position, or wire the heater in permanently.

When a permanent install is the right answer

• The heater is a fixed feature of the room — wall-mounted, staying in that position for years.

• Bathroom or wet-area heaters need permanent wiring with switching outside the wet zone.

• Underfloor heating is always permanently wired and switched.

• Higher-wattage units (2kw+) are often more reliable on a permanent connection.

• You want it on a timer or BMS separate from the heater's own controls.

When plug-in is fine

• Smaller units (under ~1500w) that might move between rooms seasonally.

• Rental properties where the landlord wants the heater to come with the tenant.

• Rooms where wall-mount doesn't suit.

• Heaters on castors — explicitly designed to be moved.

There's no shame in plug-in.

What a typical multi-heater install actually looks like

Three heaters across three rooms in one go: two rooms get wall-mounted permanent installs off existing nearby sockets, with a new spur for one of them. The third room gets the heater on castors, plugged into a new properly positioned socket. Whole job typically takes a half-day for a two-person team.

What to ask your sparky before they quote

• Will the heater locations meet manufacturer clearance distances?

• Where are the existing sockets, and will any of them work?

• If a new socket is needed, can it come off an existing circuit or does it need its own?

• Is the existing switchboard set up to take a new circuit if needed?

• Will the install be tested and certified?

How Cosine handles it

We come and look at the rooms with the heater boxes in hand, mark up where each one will sit, work out what wiring's needed, and quote on that basis. Certificate of Compliance issued for any new permanent wiring.
