Free with your BOXT
Honeywell Wireless Smart Thermostat RRP £199.99
Get the latest in central heating technology free with all wall-mounted combi boilers from BOXT - it's available as an optional upgrade for other boiler types. Control your central heating from your phone. Adjust room temperatures, set timers or switch the heating on or off, whether you’re in the house or not. It’s easy to do it all from the intuitive touchscreen on the thermostat, too.

We protect your boiler for free too
We put a FREE filter in every BOXT, worth up to £130 RRP. It filters nasties from the system water to protect the boiler and keeps it in top condition for longer.
