Energy conservation measures apply to hot water heating also. Water heating is a significant energy user in almost all facilities as it is a major part of total energy costs. Water heating systems usually operate continuously, so their losses are continuous. Inefficiency in water heating is caused primarily by inefficiency of the heating equipment and distribution pipes.

Day to day activities

Field Inspection Check List

• Leakages - check all pipe connections and valves
• Filters – inspect, clean or change
• Pumps
• Ensure thermostat is set according to ‘best practice’
• Timer (time, mode (day/night, holidays) set back
• Actual room temperature

Recommendations, advice and tips

• Regularly clean the pipe system
• Avoid unnecessary use of energy and maintain comfortable indoor climatic conditions in relation to the outside temperature
• The thermostat should be set according to best practice guidance (This will vary from country to country)
• Thermostats should be checked, cleaned and calibrated periodically
• In public areas, Thermostatic Radiator Valves (TRV’s) should be locked or not used
• Switch off extractor fans (in kitchens and toilets) if possible, especially
  overnight and in weekends (they also extract heat)
• Insulate all pipes and equipment in unheated areas
• Installing proper heating and hot water controls can reduce the running costs of your central heating system by up to 20%
• Open south-facing blinds on sunny winter days
• Plant deciduous trees on the sunny façade side
• Use highly efficient electric motors
