I am in the process of replacing my HW & CH programmer. The current Siemens RBW9 unit has the dip switch (5) set as gravity fed. However, I have a grundfoss pump and what I believe to be a Y-plan system with a three way valve, hot water cylinder in the airing cupboard with a cold water tank and...

I am having a new Viessmann 100-W 25kW heat only boiler fitted and trying to decide whether to go with weather compensation or something like a Tado thermostat. Currently we normally use the heating from about 3:30pm in winter until about 8pm on 20c then I let it set back to 15c from 8pm until...

Hi everyone, I am looking to change my DT90e thermostat for a Danfoss TP7001 (battery version) and would like some guidance / confirmation as to the correct wiring up. I currently have the DT90E with the Brown wire in A and the Black wire with Brown sleeve in B. There is nothing in C, the Grey...

Hi, I am hoping someone can give me some guidance. The job I want to do is simply to change a dimmer switch for a normal on/off switch. I have done this many times before, but not seen the kind of wiring I have on this one. The dimmer switch is for a bathroom (outside of the door), it also...

Hi everyone, I have a Worcester bosch 19/24cbi boiler and would like to know what you think the best position is for the dial on the front and if there is a difference for winter or summer? The dial on the front has a dot at the 3 o'clock position, but the manual doesn't explain it at all...

Hi, Today I noticed paint peeling off the wall just above the skirting board in the lounge. Upstairs there is a WC, I believe the pipework for this is further over though. Anyway, I went to check outside and discovered the outside wall brickwork to be very wet and the moss in that area...

Hi, I have a worcester bosch 19/24 cbi. It was very noisy, however after using some fernox f2 this has dramatically improved. The issue remaining is that when I switched on the hot water, the boiler fired up for initially about 15 minutes, then went off for 3 or 4 minutes. After having...

Hi, I have a Worcester Bosch 19/24 cbi boiler. The question is: Would I be better going for Worcester Bosch's cover to get their specifically trained Engineers for this boiler, or does it really not make any difference and is the same as going with any reputable and competitive company?

Hello, Please excuse my naivety, but I was wondering if somebody could shed some light on a boiler problem for me and give an opinion for the second issue as to whether it is normal or not? 1. The boiler (W-Bosch 19/24CBi) sometimes will refuse to re-light (if at all) for heating the DHW...

Hi, I recently purchased a Honeywell DT90e and it has been driving me crazy as it seems too sensitive, turning the heating on and off constantly. I agree the temperature remains quite even, but often the boiler fires and the rads barely even get luke warm. Surely this is a waste of gas...

Hi, I believe there is something wrong with the way my boiler is operating and wondered if you guys had any ideas? I have an open vent system with a Worcester Bosch 19/24cbi boiler. The problem is that although the boiler ignites fine and seemingly runs ok, after an initial period of...
