Rated 5 out of 5 by from Reaction time of thermostat Tried other makes of thermostats but found them not to to be reactive to temperature rise - therefore hot water was getting too hot. Replaced with this Honeywell thermostat and system is now working perfectly.

Rated 2 out of 5 by from Expensive for what it is. Suspected Design fault The centre spindle failed. The whole mechanism depends on this being strong. It is too small in diameter and fails rendering the unit useless. Not worth the money.

Rated 5 out of 5 by from Honeywell L641A Cylinder Thermostat Bought to replace broken OEM. Centre plastic spigot seems to fail through heat fatigue over time but had lasted 10 years.

Rated 5 out of 5 by from Hot product! Hot water on central heating was luke warm. Thought it might be old thermostat. Bought this and it fixed the problem. Really easy to fit in about 5 minutes and works a treat.
