Has anyone had any success in preventing their boiler from short cycling?

Well they suck ass when you fit a dumb thermostat. With a proper weather compensation thermostat they work great.

That's true, but it also makes no sense that one radiator in a zone, which could be your whole house, dictates whether the rest of the building gets heat.

Your smart thermostats are only good for comfort - weather comp is good for efficiency as well. And how about return temps?

The Vaillant one I am suggesting isn't even "smart" in the sense I think you may be assuming. It is just the proper thermostat for that boiler.

I am speaking from experience here btw. I had a 7.5k refurb (new Vaillant EcoTec 624) and opted for Hive as I had the TRVs and knew no better. I did extensive research and realised I would have been significantly better off with the Vaillant controller with weather comp. I was too far down the road though and lacked the proper wiring center. And I wanted smart features which are an additional gateway module.

Oh no, it's not smart at all.

I know having weather comp would be great, but I normally have the flow temp set around 50-55C anyway, so I'm not sure it would make a great deal of difference to consumption.

The issue I have with all these things are that the upfront cost is high, but gas is very cheap, so the ROI would be long.

Fair -- I think your 75£ idea is neither here nor there though. At least top up 50 and get Hive/Tado and get the smart/program the timer from your phone or do nothing and extend the wire.
