I am having a new central heating system fitted and have been given the option of two boilers Worcester 32 compact or Worcester 34 CDI classic. The 34 CDI will cost £200 more than the 32 compact. I gather that the 32 compact can fit in a kitchen unit but this is of no importance as it will be fitted in a bedroom. There is one bathroom in the house and this is unlikely to increase in the future. I wondered if there is much to choose between the two and whether it is worth paying the extra £200 for the 34 CDI?
