Rated 5 out of 5 by from Boiler Looking around for a Worcester 30kw combi boiler at my usual merchants to be told either not in stock or waiting on delivery so over 5 days shortest before I can collect. Check screwfix website as advert online kept popping up on search. I normally don't do this type of method as sites want details and have been bombarded with spam messages, . However screwfix was a breeze and had the boiler I require and can deliver 1-2 working days which saves me time. Also cost of boiler was the cheapest.

Is 20 kilowatts enough to heat 9 radiators in a 3 bedroomed house with one bathroom ?

Asked by: Nickj1000
Hi Nickj1000, Generally speaking a 20kw boiler is enough to heat 9 radiators. There are, however, too many variables between properties to conclude whether or not this boiler would be suitable in this case. You will need to consult a central heating professional to select the correct boiler size for your house. If you would like to discuss this further please don't hesitate to contact us at Worcester Bosch Technical Support on: 0330 123 3366.

When it says not compatible with solar panels, what exactly does that mean? Solar panels go through inverters and a battery bank to ensure continuous supply at 230v

Asked by: markythesparkykinda
Hi markythesparkykinda, Some of our combination boilers accept preheated hot water from a solar heated hot water cylinder via the use of a temperature sensor accessory on the incoming cold supply in the boiler. The Greenstar 2000 cannot accommodate this system. This is what Screwfix mean when they say it is not compatible with solar panels. If you have further queries concerning this don't hesitate to contact Worcester Bosch Technical Support on: 0330 123 3366.

Installing Nest Thermostat with this boiler

The placement of the external 230v control panel is not obvious; The visible connections are [2xground/+/-] (left hand side) & [TW1/thermometer/I3/Bus] (right hand side). Where is the external control panel within the unit?
Asked by: Lambo94
The switch live is labelled as LR. Please ensure you definitely have the Greenstar 2000 and not the Worcester 2000 as this was not compatible with third party controls.

What flue goes with this boiler

Asked by: Danielfinleyarlo2021
This depends on what configuration you are planning on doing, but any of the current wall hung boiler gas flues would be correct.
