Conventional boilers explained

The conventional boilers are being slowly replaced by combi and system boilers where appropriate (If cold water pressure is an issue, it may be better to stay with this type of boiler).

The system is being fed by 2 header tanks in the loft. There is a pump that is used outside the boiler to pump water around the radiators ensuring the central heating system is working. The hot water is stored in a cylinder which supplies hot water when required.

In addition to this, these systems require hard wired control systems.

The issues with this type of system are

  1. More expensive to operate.
  2. More components to go wrong.
  3. Can suffer with low water pressure on taps close to the tank.
