Now I have to admit my knowledge becomes a little vague at this points so please forgive me.... In terms of a sealed system, I believe it is. Its not a combi, I have a water tank upstairs and a filler tank in the loft. I don't believe I have anyway of telling the pressure, no obvious dials...

Thats right, the boiler fires up, or appears to. I have tried again this morning but no heat emerging. I don't know whether i may be causing damage doing this so have switched off again. I don't think a lockout is occuring. As I say, there is a 'click' every twenty seconds or so, but I am...

Hi All, We had a Grant 15/21 'Utility' oil fired condensing system boiler with a standard flue pluming kit and 'Magnaclean' system cleaner fitted on the 13th March 2012. It was serviced last year and its been great all over the winter. We had out tank filled yesterday but the heating has...

Wow, thanks for all the replies. In answer to the question, no, I have not changed anything, no bulbs or the like. I am happy for the fan to operate with the light switch, or not at all really. So I probably need to get the control panel off and have a proper look then (obviously with...

Hi there, We live in an oldish house that has had a downstairs toilet added and an en suite in the master bed room. Both of theses rooms benefit from a fan which is turned on when you use the light switch in either. The fan is in the loft and it is connected with ducting. Normally the fan...

The black screw on top was pretty much turned all the way to the right, does that sound correct as a setting? I basically replaced like with like buying an auto air vent from screwfix for a fiver. Fitted it no problem and doesn't seem to be leaking (famous last words). This time the screw is...

I have just been up and turned off the valve. I also took a picture and dried everything off, just to see if water appears anywhere else. You can see on the top of the valve a wet patch, so water appears to be coming from the very top. I wonder if this has been leaking for a while.

Morning, I have just woken up to water coming through my daughters ceiling, which is always a pleasure! So, I have been up in the loft, half asleep, and I think I have traced the problem to an auto air vent valve which I am presuming is on the heating system (which is off) which is leaking...

I have just been in the kitchen and timed what the boiler was doing. It seems to run in 3 minutes cycles with 1.45mins on and 1.15 mins off. Temperature has gone up to 17c at the thermostat since turning boiler up with radiators definitely hotter to the touch.

Well I definitely need more radiators in the kitchen, its a big room that did have a oil range thrumming away which now has an electric over instead, I do need more heat down one end. Anyway, I have pushed the boiler output up to half way from the minimum it was on. We will see what happens now.

Well I just did a test and I am a bit surprised. As I say, I have never adjusted the output on the boiler. So I twisted the knob clockwise, so I could answer the question, and there is not much play at all. It will turn perhaps a 1/4 of the way around, so when it is fully clockwise (the output...

Thanks for the reply. I will need to do each room of the house as I get round and decorate. There is insulation in the loft spaces although the extension roof is non-accessible. I did have the roof off last year so I know its insulated. I guess I will loose a fair bit of space off rooms...

Thanks for the replies. dcawkwell - funnily enough I was just going onto their website I will check it out. D_Hailsham - I am not sure, if I take the front off the boiler there is a knob marked "Heating Temperature" - there are no values around the outside although it is marked, similar to...

Most of the radiators are doubles but not all have convector fins. I am planning to add an upright radiator to the kitchen anyway. When we originally had the boiler installed the plumber sized the radiators and I think he said they were about right, but evidently not. Is there an easy way...

Hi All, I moved house a year ago and upgraded the heating system (oil). I have been insulating where I can to try to ensure the house is as economical as possible. My house was built around 100 years ago and has had a couple of extensions. The last of which appears to be a cavity wall where...

Hi there, I moved into my end of terrace three bed room house about a year ago and I installed Grant 15/21 oil conventional boiler to run my eleven radiators (all with thermostats but all at maximum). Oil usage has been around 1700 litres with about 200 still in the tank from that. I am...

I am in the process of updating our bathroom and this includes moving from a laminate floor to a tiling floor. On removing the old flooring i noticed the concrete was quite damp, i put alot of this down to the fact I had a radiator leak the day before. Anyway, I have waited three days now for...

Yeah, I thought that too. Right, the walls it is then!
