I can't get to the pump without taking the floorboards up in the bedroom above the boiler so that hasn't been touched.

I've managed to get in the loft and get to the header. It's got water in and pushing the ball cock down is letting water in but the bottom of the tank is full of gunk. I've back filled from downstairs and have got water in all rads. Turned on boiler. None of the radiators are getting...

I know it's Sunday but I'm hoping there is someone around to stop me from having a nervous breakdown!! I have drained my system to carry out some work. When I drained the system I did so from the bathroom radiator as I didn't have a drain cock anywhere. This drained the bathroom radiator and...

No idea I'm afraid, I'm at work and the Danfoss is on the wall at home.

No problem :D Would you be able to have a quick look at the wiring diagrams I posted and see if it's likely to be an easy switch over? I'm also struggling to figure out where the thermostat would go? Obviously the bathroom and the kitchen are a no-no, but that then leaves the choice...

The Danfoss is wired into the boiler in the kitchen. Why couldn't the new unit go there? I understood that there are 2 parts to that Horstmann unit - the wireless thermostat and the receiver? So the thermostat sends messages to the receiver and the receiver then sends messages to the...

This is what I currently have: http://heating.danfoss.co.uk/PCMPDF/2468v05.pdf This is the wiring for the Horstmann one: http://www.horstmann.co.uk/files/1314/0014/7617/RF_Programmable_Room_Thermostat.pdf How easy to swap one for the other looking at the relevant wiring diagrams?

Something like this? http://www.screwfix.com/p/horstmann-hrfs1-programmable-room-thermostat/93829

Can confirm it's just the 2 pipes feeding the cylinder. In terms of the danfoss unit I'm happy with its functions as a timer unit so it is just the thermostat that's required. What I wasn't sure of is does the thermostat have to be wired into the boiler or can it be wired into the...

We only get hot water when the immersion has been on, once it's been used up, we have no more hot water until the immersion kicks back on again. So, I would assume this means the boiler isn't heating the water? The time control for the boiler is the Danfoss 103e5 that I mentioned earlier...

If that's the case, what is the best way to use that? I assume that if the control is on low, then the radiators will be cooler and therefore take longer to heat up the room and ultimately use more gas? So if I turned the control up higher, the water temp in the radiator would be higher...

The boiler is a Potterton Flamingo RS13: http://interpart.partsarena.eu/System/DATA/Dx/DS1/installation/2108/I02-2108/I02-2108.htm That guide is from 1976 so shows how old the boiler may be! As far as I have always been aware, the hot water is fed from the cylinder which is heated by...

I've lived with it like that for 7 years since I moved in - no wonder the gas usage is always horrific when the heating is on. Presumably that's why the boiler seems to be always firing up even when it's on as there is nothing telling it that the rooms have warmed up? I have read it's...

I've currently got a Danfoss 103e5 control unit connected to the boiler which just provides on/off function. As I would probably go for a wireless thermostat, does the control unit for the thermostat completely replace the Danfoss unit or is it possibly to wire the thermostat into the Danfoss...

Hi all, I've posted a couple of previous questions which have helped me this far but I want to be sure I'm doing a decent job as I'm making the effort so just after a bit more guidance. I managed to get the central heating drained down using a 3/4" hozelock connector to the bathroom...

Sorry to sound thick, but is that straight vertically or straight horizontally or doesn't it matter? There is some pipework that runs under a floorboard just inside the back door that is easily accessible so would I be able to fit the drain tap to that section? Also, can the tee fitting be...

I thought that might be the case! The lockshield valves are leaking on a few of the rads, one of them is completely gone so I've had to close it. So I'm going to drain the system and fit new lockshield valves, possible new TRV's too as the ones we have now are not doing the job properly...

Morning all, Sure this will be a quick one for someone to answer........ I've searched high and low on the pipe work for a drain point and there is definitely not one on any of the downstairs radiators. The only one I have found is this one which is located on the pipework at the side...
