I want to use this as a pipe stat for a towel rail circuit. Is there any way I can extend the capillary probe as the distance is 2.5 meters?
It works by expanding gas, so cannot be extended.

Hi, can I use this to switch a pump on when my wood burning stove with a back boiler gets up to a suitable temperature Thanks
Yes you can.
We would like to order the following please: 2 of the limit versions of the Capilliary Aquastat and 4 of the regular Capiliary Aquastats please, how do we go about this given that the limit version is not on the website?
Please email sales@heatingcontrolsonline.com and they will send you a link.
Does this thermostat have three terminals (common / normally open and normally closed)?
Yes it does.
Could the bulb be used in a dry pocket to control overheat of a therostore tank?
Normally a limit thermostat (with manual reset to switch it back on) is used for overheat protection. This is a control thermostat, so works like the main thermostat. Using a control thermostat for overheat protection may leave the user unaware that the first thermostat has failed. We can obtain the limit version if you need that.
