I’ve moved house recently and have now got a 2004 Vaillant EcoMax 835 with a very basic central heating control system – on off times and water circulation temperature. There is no 7 day programmable timer or room thermostat, so we are not running it in the most cost effective or energy efficient manner.
How difficult is it to set it up with a wireless thermostat controller?
I’ve had a quote of £175 for supply and fitting of a Honeywell unit. I suspect that the kits costs around £80 so the rest is the plumber’s mark up and fitting cost. I don’t mind paying if it is a complex job, but if it can be done easily in 5 minutes without risk of knackering everything up I’ll do it myself.
