I have 8 double rads and 4 single on two floors. The pump is a Wilo 50 5m located on the top floor and there is a Honeywell 3 way diverter valve. I have X100 inhibitor in the system. The boiler is on the ground floor. Rads take about 45 mins to heat up at which point I can hear a couple air...

Thanks to both of you for replying. It is a 32 amp MCB and I think I will probably change this to 20 amp as suggested. I am reluctant to pursue my neighbours as they are both quite old. I am not sure if they themselves was responsible for the drilling or if they had a contractor in. I...

Hello All, I would appreciate some advice. My MCB ( sockets ) tripped. I reset it and it tripped again after 10 mims. Then it started tripped straight away. The MCB controls the sockets in my kitchen. I called a electrician who told me in two minutes that the entire kitchen would need...

Agile, I'm confused. Are you saying that if water is dripping within the heat exchanger then this is classified as dangerous. I thought that any overheat situation the reset stat would kick in. BTW, it sounds more like trickling when I place my ear against the boiler casing even when the...

Following on from a previous post about the installation of a restrictor ( which works fine ) I have another problem. After installing the restrictor and refilling the system I seem to have air in the heat exchanger which will not go away. The boiler heats all rads fine and hot water is...

Just checked it again and the vent pipe is on the return pipe to the boiler. The screw air bleed is attached to 6" 15mm copper pipe which is soldered onto the 22mm copper pipe using a reducer. Thinking about it, it seems to me that the whole sytem would not work if anything more than 6" of...

I bought a Conex 22mm gate valve BS5154/B 9 Bar / 120c ( hope its the right part ) The configuration of the sytem is as follows -: The pump is located in a cupboard and is connected from the boiler flow pipe 12 inches above the pump is the 3 way mid position diverter valve. Right off...

Checked the feed tank today and all seemed o.k apart from some surface scum, this being due to the Fernox inhibitor in the system I am told. Took off two rads and flushed them out and replaced them. The feed tank water level dropped and filled the rads fine. I can only guess that the feed tank...

Checked the valve today and read the following Motorised valve details: Honeywell 9238 Other numbers: V4073A 1039 T50 Brass Ts88 Pump details: Wilo -110 running speed 2, 2000rpm Hope this helps Thanks again

Thanks for the reply! There is a 3 port valve next to the top pipe entering the hot water cylinder. Every time someone opens a hot tap in winter the house drops in temp while the hot water heats up. I really thought that slowing down the amount of hot water from the boiler to the cylinder...

Following on from a previous post, I would be grateful if someone could answer a question. I have a Potterton Profile 80e running 12 rads and the problem is that when the hot water cylinder switches on the temp in the rads drops off to almost cold. At the same time the boiler starts to...
