Useful Information:

It is important that you service your gas boiler and other gas appliances annually in order to ensure 
 your gas appliance is safe to use. 
 

It also helps keep your monthly gas bills down and your boiler operating at its optimum efficiency level.
This will help prevent against costly breakdowns and in the
 long run will extend the life of your gas boiler and put money back in your pocket. When you have your boiler serviced make sure to get a copy of the flue gas analysis and keep it safe until the next service is due, the next engineer in turn will be able to compare performance with the latest service analysis and make any adjustments as required.  

All gas work is carried out in accordance with IS 813 (Domestic Gas installation Standards).

Heating controls explanation:

Heating controls consist of the following, which can be considered as zones or zone control. The independent control over certain areas or upstairs, downstairs, hot water circuits. Most systems can be upgraded to fully integrated heating controls with minor pipe work modifications. Control packs consist of: Digital programmer, room thermostat, cylinder thermostat, motorized valves and wiring center. 

This is a quick rundown on how they actually work.  Programmer calls for heat then sends a signal to the Room thermostat which senses that it is below the desired temperature on the thermostat which sends a signal to the Motorized valve telling the valve to open that a heating call is required. Motorized valve sends a signal back to the Gas or Oil boiler to activate and start heating until the thermostat reaches temperature.


Fully integrated heating controls could save between 20-30% annually on your fuel bills
