Presentation Transcript

  1. HOT & COLD WATER SYSTEMS

  2. HOT & COLD WATER SYSTEMS To heat a property with a boiler, water is heated and then distributed to rooms pipe work. Heat is introduced into the rooms via convection radiators. RETURN FLOW RADIATOR RADIATOR BOILER RADIATOR RADIATOR RADIATOR RADIATOR

  3. HOT & COLD WATER SYSTEMS A boiler with a cold water header and hot water storage tanks can be used to heat a house. Alternatively, a combination (“combi”) boiler may be used. Combi boilers are suitable for small dwellings, and simultaneously supply hot water for heating and sinks / taps.

  4. HOT & COLD WATER SYSTEMS Cold water storage tank Hot water storage tank Boiler Radiators

  5. HOT & COLD WATER SYSTEMS Gas meter with incoming mains and isolation valves

  6. HOT & COLD WATER SYSTEMS Close-up of a gas meter readout

  7. HOT & COLD WATER SYSTEMS Gas governor and meter in a large University building

  8. HOT & COLD WATER SYSTEMS Above: Domestic cold water storage tank. Right: Hot water storage tank

  9. HOT & COLD WATER SYSTEMS Hot water boiler.

  10. HOT & COLD WATER SYSTEMS Isolation valves: if the handle or screw head is parallel to the pipe, then the valve is open.

  11. HOT & COLD WATER SYSTEMS Flexible filling hose of a combi boiler

  12. HOT & COLD WATER SYSTEMS Inside combi boilers

  13. HOT & COLD WATER SYSTEMS The burner of a combi boiler in operation

  14. HOT & COLD WATER SYSTEMS The boiler house of a University building under construction.

  15. HOT & COLD WATER SYSTEMS Hot and cold water is distributed via insulated pipework

  16. HOT & COLD WATER SYSTEMS Pipework in a small domestic heating and hot water system

  17. HOT & COLD WATER SYSTEMS Large panel radiator in an office building.

  18. HOT & COLD WATER SYSTEMS Above, radiators, with fixing brackets and thermostatic radiator valves.

  19. HOT & COLD WATER SYSTEMS Under-floor heating can also be used to heat a building. Hot water is pumped through pipes which are set into the floor screed. As heat rises, it warms the floor slab and the air in the room.
