Traditional boiler with cold water tank & hot water cylinder
If you are replacing an older model of boiler, the chances are that you will have a regular (also known as ‘conventional’) boiler.A typical regular boiler system incorporates a boiler, extended controls, a hot water cylinder which is often fed by a cold water storage cistern located in the loft and a feed and expansion cistern – also located in the loft.
The advantages of a traditional system are:-
- You have a stored water supply (normally 50 gallons 227 litres).
- You heating system works under a low pressure.
- If you hot water cylinder has an immersion heater (electrically heated) you have hot water back-up, in case the boiler fails.
The dis-advantages are:-
- Poor water pressure on both hot and cold taps, except the cold at the kitchen sink which is main water pressure.
- You heat the water in the hot water cylinder to 60 degrees than may not use it all.
- You have water pipes and cold water storage cistern in the roof which may leak or freeze.
