Yes I came to that conclusion last night after the 2nd drain down of the system followed by refilling/bleeding rads = same result L9/H9. Will call Ideal today as my usual CH servicing company didn't carry the spares for the HE 24. I have got of a sneaking feeling that if installing a new...

dumb question. where is the AAV on an ideal isar? Is it the capped valve exit on the top of the unit or that the expansion valve?

Yup well aware of its ****e status - but wasn't when we bought the house with it already installed :( anyway it must be worwhile draining it and refilling in the hope it may dislodge the sediment?

So this weekend the boiler gives me this error message and stops providing CH or DHW. Looking at the ideal website they suggest to check the TRV's. I just fitted a new rad 2 weeks back so there may well be something in there. I got some questions and would be grateful for any answers:- - I...

I have tried the reset key but it doesn't do much. I have turned the whole thing off now when I do turn it on I either get d, L9 or H9 status (with boiler light) the boiler itself feels warm so perhaps it does fire for a while. I suppose it could be the pump - not sure :roll:

so 1.5 bar; all TVRs turned full on reset bolier at power. Turned on with CH switched to ON and nothing but a H9 warning. No noise when I turn on hot water tap...looks time for a visit from the central heating company Adam :cry:

Thanx. Pretty certain the pressure is going up except when CH was working. When you say "Expansion vessel needs recharging with air" is that a simple task a DIYer can do or is a job for a service engineer? Also what position should I leave rad thermostats on when trying to recover from...

Hi, A couple of weeks back I installed a new rad and tested the whole CH system for an hour and it worked fine. Yesterday we found there was L/H9 status warning with no HW available so I did some research on here and droped the pressure to about 1.1 bar reset it & it started working again...

Hi, So got the carpet kicker, carpet, underlay and gripper boards to cover a small room 2.5 x 2.5ms. I am going to start out by fixing one machine cut edge to first wall then roll out to the opposite wall but hat I would like to know is how much to overcut the carpet intially? would an...

So today I finally added a new rad to the the spare room (it had no heating before). Drained off the CH loop, bled radiators, fixed new rad to wall, tee'd off the the supply and return pipework, solder necessary pipework, see up or thermostat etc, turned back on water and was pleasantly...

I will drain all the rads then. Only talking 5 in total. Thanks for help

Hi, thx I am putting the new rad in the bedroom upstairs ( first one in the loop from the boiler) I should only need to drain the other rads upstairts right? Adam p.s yes I heard about the reputation of Ideal but it was fitted to the house before we moved in :(

Hi, Tmrw I am going to drain off our central heating loop to put in an additional radiator. We have an Ideal Isar Combi boiler and I have a couple of qustions - Dumb Question:- the pressure is currently at 1,3 bar and if I drain it until the water stops i.e bar 0 can I safely assume there...

Another question. I have got a couple of small windows that I have stripped of the old paint and I want to remove the glass in order to re-putty them. What is the best/easiest way of removing hardened putty from a wooden frame. I have heard of using parrifin to loosen the linseed putty or a...

Just had our spare bedroom re skimmed yesterday and it appears to have dried very rapidly. The plaster didn't specify a time to wait to paint but just that we should paint with matt emulsion let down by 40% water. Getting some pressure to complete the room - any ideas when the earliest I...

I was just wondering if I de-solder an existing 22mm elbow joint and then want to replace it can I simply clean up the pipework with emery cloth and then resolder it or would a compression joint be better? Unfortunately I can't cut one of the pipe lengths shorter for a clean end as it will be...

Being doing a bit of research and checked various websites out there. Finally I used a Wickes .pdf to calculate that our spare spare bedroom(2.4x2.1x2.4) needs a rad of around 1950 BTU so I picked up one today with a 2000BTU rating. The thing is this website says more like 2400:-...

thanks for your tips. For the pipe cutter do you mean this one? http://www.amazon.co.uk/Monument-22pc-Automatic-Copper-Cutter/dp/B0001P0FI6 Is this any good for cutting off very short lengths of pipe i.e trimming 1cm off the flow/return pipes to make room for the Tjoint?

Hi. I want to add a radiator to our existing Central Heating. I have replaced a radiator before and feel reasonably confident about doing the job provided I have done the research. Anyway I have locate 2 x 22 mm pipe near to the place I want to put the rad and have identified the supply...

Thanks. I just ordered the outlet pipe which apparently includes the pressure relief valve:- http://www.gainsboroughshowers.co.uk/parts-store/Gainsborough-Showers/Gainsborough-95-SDL/3346/ and I going to clean out the shower head with some white vinegar tonight
