Its called a pump overrun…the pump kicks in every now and again to either disperse any heat the boiler may be holding or to just turn itself over as part of its inbuilt maintenance routine, you do not need to get an engineer out.

I have a Worcester combi boiler installed by a national company and I am on a boiler service contract with them.
With the heating system switched off, the pump comes on for a few minutes on odd occasions (usually early in the morning) but no light is showing on the boiler and no heat gets to the rads. The system is working well otherwise.
Why is this? Should I ask a service engineer to call?

It is very difficult to diagnose central heating systems remotely, particularly on the limited information available.

If you have taken out a gas boiler service contract with a reputable company you should telephone the helpline number you have been provided with and an engineer will call to help remedy your problem. If you have not taken out any boiler service agreement npower have a heating repair service which could help. If you telephone them explain your issue you will be provided with a no obligation fixed quote for fixing the problem.

I have a Baxi solo boiler and Range Fortic F4 cylinder, both were switched off for over a month while i was having my bathrooms and kitchen changed. I have switched them back on and the boiler looks like its working and the cylinder is getting hot, however the hot water pressure is very very low from all the taps in the house (cold is excellent). There is no pressure gauge on the boiler or cylinder and i can’t work out what the problem is. Please help.

The boiler is manufactured to the highest specifications by Worcester Bosch and they hold the download manuals.

If you contact their technical helpline on 08705 266241 they should be able to help you.

Having recently moved, the house is fitted with an old Combi Boiler.

The pressure is 0.7 bar and unfortunately the previous owner didn’t leave the manual. Can I download the manual online?

Also could you advise what pressure the boiler should run at and how to increase it. Cant obviously see an external feed loop or valve.

Thanks,

It is important to switch off the heating before bleeding the radiators or it is possible to import more air into the system.

If this is the cause of your problem you could possibly remove the issue by bleeding the system again with the heating off. Have you been successful in using the loop to pressurise your system before in the recent past? or has the filling mechanism become blocked?

If you are still without heating and the filling mechanism does not work it appears that you will need the assistance of a heating engineer.

NAtional installers do install both types of system. The main difference between the system types is that an unvented system you will have hot water stored in the system under pressure. This required expert installation and regular maintenance.

Reading your comment it appears that you have investigated the options in depth and have knowledge of this area. Notwithstanding this if you require further information npower are able to send a Home Energy Consultant to your home to review the installation options and help to select the right boiler for your home.

I am looking to reclaim the airing cupboard which is in the third bedroom of our 3 bed semi. At the moment we have a 15 yr old Baxi back-boiler. with 2 growing children the demand for hot water on tap is only going to increase.

I want to move the boiler and HW storage tank into the loft, do away with the CH and HW headder tanks and balence the cold and hot water pressure.

I need to decide whether to go for an un-vented or vented (thermal store) mains preasure hot water system. Could you please tell me what the disadvantages /advantages of each system are? In addition please could you let me know if anyone can install both types of system?
