Rated 5 out of 5 by from Perfect fit and works well Really pleased with this thermostat, works well and I was able to collect 10 mins after ordering at 7pm! Connected up very easily to replace an old item that hadn’t worked for years. Needed urgently due to broken gas boiler!

Rated 5 out of 5 by from Immersion heater thermostat. Not all DIY shops stock these anymore. I can get them from my usual supplier cheaper but not on a Saturday when the customer is crying without hot water. To be honest, the difference in price isn't that bad.

THERMOSTAT CHANGE

2 QUESTIONS:- 1. My one already fitted states 12.5A 240V on it, so am I able to use 15A 240V you sell? 2. The fuse in the consumer unit is 15 amp do I need to upgraded this fuse to a bigger amp fuse?
Asked by: Anonymous
Yes, you will be able to replace a thermostat rated at 12.5 amps with one that is rated at 15 amps. You should not change the fuse in the consumer unit. It is the immersion heater element which draws the current in circuit, probably about 12.5 amps. This means that the thermostat, which is essentially a switch, must be able to handle at least that amount. The fuse is there to protect the circuit so should be rated as low as possible, in order that it will blow if the circuit current raises too high for the wiring or equipment without affecting normal operation.
