The Glow-worm Climapro is a hard wire two channel programmable room thermostat allowing the user to control the temperature and time of the central heating and hot water either together or at totally different times of the day, 7 days a week.
At Boilers2go we recommend the Glow-worm Climapro Programmable Room Thermostat for use with all Glow-worm gas boiler models for greater control over the central heating and hot water temperature and times. Also the Climapro can help improve the energy efficiency of the boiler and help towards lowering the users annual gas bills and reduce their homes carbon emissions.

In a closed central heating system water cannot be compressed so any increase in the volume, created by an increase in temperature, needs to be accomodated. This is done with the use of an expansion vessel, when the water in the system is cold the pre-charge pressure of the system forces a diaphram in the expansion vessel against the tank towards the inlet. As the temperature increases the expanding water volume pushes against the diaphragm creating additional volume for the water to enter the expansion vessel. As the temperature decreases the pre-charge pressure forces the water from the expansion vessel back into the central heating system. This maintains a constant pressure within the central heating system and helps to reduce energy and water consumption.
