If you have an existing hot water for heating system you will find that the Worcester Greenstar 18Ri boiler is suitable for your home and is an ideal replacement boiler. This is a regular boiler and typically for the design of a regular boiler it will include additional components in the central system such as a hot water cylinder for storing hot water. The capacity of this hot water cylinder will limit how many bathrooms or shower units can be fitted to this boiler.

  • A great advantage is that it can fit inside a kitchen cupboard.
  • Producing NOx and CO2 emissions at a low level makes its good for the environment.

    For a compact new build 2 bedroom and 1 bathroom(with shower over bath) house, the developer is installing a regular condensing boiler with an unvented hot water cylinder. Space is at a premium. Can we install a combi system with no cylinder instead ? What size combi system would you recommend?

  • Boiler Systems says:

    There are several types of condensing boiler ( regular, system and combi) and the choice must take into account your personal needs and the installation options in the property. It is possible to install a combi to conserve space but you also need to take into account the hot water demands you will have at any one time. A combi boiler will only deliver to one hot water draw off at any time whereas an unvented cylinder will give mains pressure to as many taps as needed.

    The power rating for the boiler cannot be calculated without visiting the property, the calculation must take into account the heat losses for the property.

    npower are able to send a Home Energy Consultant to your home to review the installation options and help to select the right boiler for your home. This visit is free with no-obligations on your part and will also enable an accurate quotation to be developed for a new boiler.

    We recommend you take advantage of this before you finalise your decision.
