## Description

Backer 7" Standard Thermostat Manually Resettable The Backermatic BMST Thermostat is an ideal solution for retrofit to existing installations as it is possible to bring your old system up to the new standard by simply changing the thermostat. Alternatively it can be incorporated into any of our Immersion range (Backer type VC) to enable the Immersion heaters to meet the new standard. Our new range of BMST thermostats incorporate a secondary safety cut-out, which is independent of the main thermostat. The new thermostats have a second set of contacts which open and limit the water temperature to 98 degrees centigrade should the primary thermostat fail. The second cut-out is non-self-resetting. FEATURES: BMST thermostat with integral secondary non-self-resetting safety cut-out Cut-out is independent of the main thermostat Can be retro-fitted to old immersion heaters Rod length of 7 inches Fits Backersafe VC range immersion heaters BMST7

Review: Great replacement - This rod was ideal for my tank and works well
Review: Most common fault on an immersion heated is a failed thermostat. - This Backer thermostat has a tapered point - what that means is it can fit most immersion heaters. I've bought three of these over the years - if a thermostat lasts about two years that is good value for money considering they are mass produced and subject to 3kw load. The third one I bought I'm still keeping as a spare years after I fitted number two. A plumber will tell you you need a new element - always try a new thermostat first, a new thermostat might cost you about £20 but you can but an element and thermostat as a unit for about £26.

## Questions & Answers

**Q: Which one will I be getting? The pictures show two different thermostats, I need the first one.**
A: The BMST7 shown in the first picture is no longer made - but stock still exists in the system.  The BMST765 is the new version - the only difference being the head colour/style - as Backer now buy the heads from Cotherm. - This info is valid as at April 2023.  Certain sellers will have run out of the old style.

### ⭐⭐⭐⭐⭐ Great replacement

### ⭐⭐⭐ Misleading photo of product
*by C***P on 1 September 2025*

It arrived very quickly. But it didn't look like the photo on Amazon, which matched the one I was looking to replace. I assume this is because it is a more up to date version of the same model, as it had the same model number, but I found this very misleading. In the end, we didn't need to replace the thermostat, but have kept it as a spare, so I can't comment on if it works or not.
