WORCESTER BOSCH 4000 COMBI BOILER REVIEW
When installed by a Worcester accredited installer.
The standard guarantee on the Worcester Bosch 4000 boiler is 8 years when installed with a Worcester filter. But when installed by a Worcester accredited installer it becomes a ten year guarantee. For this reason it makes sense when choosing your installer to use a WAI. WAI’s have been through extensive product training on Worcester products. So you know you will be getting quality workmanship as well as a quality product. Afterglow are Worcester accredited and based in Birmingham, we cover Birmingham, Solihull, Sutton Coldfield and surrounding towns a city’s. So if you’ve not yet found an installer for your new Worcester boiler give us a try. Alternatively you can try the Worcester website as they have a find an installer feature.

ERP RATING A
DIMENSIONS MM HEIGHT X WIDTH X DEPTH 724 X 400 310. THIS BOILER IS COMPACT ENOUGH TO FIT INTO MOST KITCHEN CUPBOARDS
IDEALLY THE 25KW WOULD BE INSTALLED IN A SMALL POSSIBLY TWO BED TERRACED HOUSE OR SMALL APARTMENT. BUT PLEASE CHECK YOUR COLD WATER FLOW RATE OR PRESSURE. IF ITS REALLY HIGH THE 25KW MIGHT NOT BE FOR YOU.
GREENSTAR 4000 COMBI BOILER 30KW NG
CENTRAL HEATING OUTPUT 25KW (CAN BE RANGE RATED TO SUTE THE SYSTEM DEMANDS)
HOT WATER FLOW RATE AT 35°C 12.3LITRES PER MINUTE
COMPATIBLE WITH ALL WORCESTER BOSCH CONTROLS AND 3RD PARTY CONTROLS. BUT THIS BOILER IS REALLY AT ITS BEST WITH THE BOSCH EASY CONTROLLER. PLEASE DONT BUY A HIVE OR NEST TO USE WITH IT AS THEY ARE A LOT LESS EFFICIENT THAN USING WORCESTER’S OWN CONTROLLS.
ERP RATING A ✅
Quiet mark certified only 45 decibels. This makes this the perfect boiler if it’s located upstairs or close to sleeping areas or downstairs in kitchen areas.
Bosch quality. Bosch are famous for making great products and the Worcester 4000 combi boiler doesn’t disappoint. Using the same heat exchanger as the tried and tested I junior. Which comes with a ten year guarantee.
Quick tap feature. No more waisting hot water waiting for it to heat up. Use the pre heat function to warm up the hot water heat exchanger
Looks great. As boilers go the Worcester 4000 is designed with beauty in mind. It’s stylish design will look good on any wall.
Simple to use. The user interface on the boiler has clear wording and tells you if the boiler pressure needs topping up and if there is an error. I really like this feature as user errors can save unnecessary call outs.
Plug and play controls ✅
The Worcester Bosch 4000 combi boiler can use 3rd party controls or Worcesters own plug and play controllers. Including the Bosch easy smart thermostat and the Bosch comfort two controller. The Bosch easy smart thermostat can use weather compensation, adjusting the boiler’s heating output depending on the outside weather conditions. This can give energy saving benefits as well as more comfortable conditions. The comfort two uses load compensation which also reduces the boilers output but by room control rather than weather compensation. For this reason it’s a bit of a no brainer to use Worcester Bosch controls over any other brand to get the most efficiency out of the appliance.
