Launched in June 2013 the Worcester Bosch Greenstar 30Si Compact is the big brother of the 25Si combi boiler.
Despite being able to deliver a flow rate of 10.7 litres per minute its compact size (it measures 69x39x28 cm) means you can install it behind a standard sized kitchen cupboard.
The hot water output would supply enough hot water for homes with one bathroom but would be poor choices for properties with multiple bathrooms.
With a Seasonal Space Heating Efficiency Rating of 94% the Greenstar 30 Si is more efficient that the old Si range and can be used with a wide range of optional mechanical digital and wireless programmers.
You can control the Hot water and heating separately allowing the flexibility to save money by reducing the temperature of one or both but you will need extra controls (like a room thermostat and thermostatic radiator valves) to get the most efficient set up.
This boiler is recommended by the Energy Saving Trust.

Reviews
A combi boiler is the cheapest replacement method as your conventional system will almost certainly require some expensive alterations to bring it in line with todays Building Regulations which is a mandatory requirement The combi system or any other for that matter would require the valves to be thermostatic on the radiators except one and in that room a room thermostat would have to be fitted(unless of course you already have them). The hot water cylinder will need to be replaced with a high efficiency one and they are several hundred pounds without fitting. As has been stated you will get all the hot water you need at the turn of a tap but do get a good boiler. I personally favour Baxi, Glowworm,Potterton and Worcester Bosch but there are others. Do yourself a big favour and get 3/4 prices inc BG if you wish and you will see a huge price difference between BG and any others although I understand BG are lowering theirs and their systems are no better or worse than any reputable independent installer. Get recommendations from friends if you can rather than just picking from the directory.
