Top quality, at a price.
Good quality product which last for years, it's not the quick release type, so a drain down is required but my heating system has isolation valves on it so no big deal.Not the cheapest but you won't end up changing it every year.

In a stored hot water heating system which has no room thermostat or cylinder thermostat the existing wiring can be used to provide Boiler Interlock by fitting Sundial RF 2 Pack 3.
The L641 is a water temperature thermostat designed for surface mounting on domestic hot water cylinders, it is supplied complete with mounting strap for rapid and easy installation, so draining of the system or tapping the cylinder is not necessary.
