Worcester Bosch Release Details of Latest Si and i Junior Boilers

The Worcester 28i Junior Boiler

As 1 of the UKs biggest manufacturers of Combi Boilers, Worcester Bosch are always looking to develop their existing range of condensing boiler models.

As such details have emerged that Worcester have redeveloped 2 of their biggest selling ranges – the Si and I Junior’s. Here’s an overview of the main changes:


25Si and 30Si

The Si range has undergone significant change, with the old Si models being changed into Compacts. The name ‘Compacts’ refers directly to the streamlined dimensions of the new boiler units and showcase the biggest difference.

At 690mm (h) x 390mm (w) x 280mm (d), the Compact series follows in the footsteps of the CDI Compact series (unveiled in 2012), allowing homeowners to hide their boiler away neatly out of public view if required in cupboards.

It also has a brand new heat exchanger and comes pre-plumbed, making it easy for installers to fit. The Si range therefore remains a great choice for small to medium sized properties with 1 bedroom.


24i and 28i Junior

The i Junior range of boiler have been revamped to be even more compatible with Worcester’s range of latest heating controls and is now more efficient than ever in standby mode.

However the biggest change is to the hot water temperature control. The previous incarnation of the I Junior series had an automatic hot water temperature, so homeowners were unable to control this, however this can now be set from the boiler front itself. This obviously means the homeowners can look to be a lot more efficient and reduce their heating bills.


Both boilers are covered by Worcester’s excellent warranties and remain fully compatible with Worcester’s range of heating controls. To find out more, why not contact Direct Heating Supplies on 0800 181 4488.

Micro-zoning your building to save energy and money

With gas and electricity bills reaching an all-time high, the idea of implementing energy saving measures must become more than just “wishful thinking” for everyone, whether we’re talking about home owners or business managers.

While most non-domestic buildings are centrally managed with the help of a complex Building Energy Management System, that’s rarely the case with domestic users, who typically require a more affordable system that’s also easier to use.


Thermostatic radiator valves are the simplest micro-zoning solutions out there (and also, the easiest to install), since they’re used for setting the amount of heat users get from each single radiator. While not being extremely accurate, the difference between two consecutive values is quite easily noticeable.

Naturally, by lowering the amount of heat generated by each radiator or switching them off altogether, the boiler powering the central heating system will reduce its output, which will immediately translate into less fuel being used and lower energy bills.

However, basic TRVs offer limited functionality an no scheduling options, which is the reason why programmable TRVs were developed.

Programmable TRVs (wired or wireless) represent the next logical step in the evolution of TRVs, since they grant users extensive micro-zoning options. In fact, one can turn every single room in their house into a heating zone, with its own heating pattern.

Basically, depending on the planned use for the room (or area) where the radiator is placed, home owners can easily set the functioning times and temperatures for the respective unit, using the programmable TRV.

The functioning intervals and associated temperatures create the heating pattern, which is saved within the valves’ memory. Depending on the type of valve, the heating pattern can be set to be repeated over a period or time, or several different heating patterns can be implemented.

By using specific heating patterns that match their daily schedules, users will be able to optimize the radiator’s functionality, reduce the amount of required heating and, as a direct effect, reduce their overall energy bills.

Wireless programmable TRVs are more convenient than their standard counterparts since they enable users to control each valve from a single location (their PC), and implement changes in a much simpler and more straightforward manner.

Regardless of the specific type of radiator control you’ll ultimately decide to go for, it’s very important to remember that even lowering the temperature by a few degrees in a room you’re not frequently using could save you at least a few pounds on your heating bills, and that’s just the start.
