Can anyone Recommend a thermostat

Hi,

I have underfloor heating hooked up to a boiler and buffer tank - and for efficiency's sake wanted the following:

- when the tank temp drops below 35C - start the boiler
- when the tank temp goes above 55C - stop the boiler

the idea here is to have the boiler come on for a decent amount of time and not have it stopping and starting all the time if just one temp controlled on/off.

I assume this requires 2 stats and some controller.
The only thing I've come accross is a single temperature stat.

Can anyone suggest a stat/controller that allows 2 temps to be set?

This one should be what you are looking for . Have one on my boiler it allows you to set on and off temp.:D
