aAsk a Tradesman

Hi,
I ,over into a property five years ago which had a newly fitted combi boiler. I have just been informed, from another tradesman looking at my kitchen, that it is incorrectly installed! I am missing the pipe that runs to outside! Could anyone please advise on what this pipe is called ?
Thanks! Julie

I need a new condensing combi boiler for my 3bedroom terrace with 2 bathrooms and have been recommended the Wocester Bosh 30si boiler, is this the right boiler for me??

We have no central heating in our home at all and are currently getting quotes. Everyone is recommending a different make and size boiler and now we are unsure what we should be going for. We have a 3 bedroomed semi, with a bathroom and seperate toilet. What would you recommend ??

Our small bedroom has 2 external walls with the longer one being quite exposed although rendered has recently been sealed , the shorter one has the window and radiator. Our problem is the longer external wall has patches that damp to touch although not black mould yet .The plaster is not damaged and we have painted with a no more damp treatment and dry lined and painted. Would we better to move the radiator to the long external wall ?

Hi All

I have had an intermittent fault with my system since around November 2012. I have the Drayton RF1 wireless stat and receiver and for the last couple of months it has every now and again just decided not to switch on the Heating at the timed selection. It is intermittent no particular time. Seems to work o.k at switch on in the morning (perhaps colder) but usually the timed afternoon heating session it fails to fire and no interaction on my part will make it fire. Stat is working, flame comes up no problem and light turns green on the receiver but does not light up from the boiler and pump. So usually I give up at that point and leave it and then low and behold the next morning at the first switch on time it fires up.

I have not replaced the wireless stat and at the moment everything is
pointing to that, I cannot work out why if the green light was on, why the signal would not fire the boiler, completely bewildered by this! I had also noticed that even on evenings when the heating had worked why later in the evening if the stat switched off the heating due to reaching temperature it sometimes would not come back on when the flame reappeared until next mornings cycle started.

So I've been on the internet and read that the likely cause is the capacitor in the SCR breaking down and not providing the signal to the boiler to fire. But
I don't know if this is correct and if it is, can I get it fixed?

I've had a quote from a trademan to replace the wireless stat and receiver and that came in at £210 which is quite expensive so I would like to explore
if there is a cheaper alternative option.

All advice would be welcomed.

Thanks in advance

Had Worc Greenstar 15Ri LPG Regular Boiler installed 4yrs ago but also need the open fire in winter, even when thermostat is flat out on 30! (boiler too small ?)

last year had heating leak under concrete floor so then re routed ground floor heating pipes overground, (think from rad to rad on one loop?) since then its even colder in house, plumber also notes that pipework from boiler is still small size and should really be 22mm which he will now change from boiler to first rads, he said this will make a difference.

We wonder if the boiler size is too small anyway. house is only 2 bed but large and open plan, over 300yrs old with solid walls and concrete floor. also open to elements one side which is also mainly all windows, we also find water doesnt get very hot when rads are on- ie struggling to do both things!.

Current boiler is only 4yrs old and nothing wrong with it, but only 15kw do we need to purchase a new boiler say 30 - 40kw for this type of property?

Your help would be much appreciated...

We have been having a few minor problems with our Valliant combi boiler (had pressure gauge replaced about 5 months ago and now realised it is not working again - Got a good plumber who says its a problem with a 'split in the vessel and pressure release' he cant replace it as its at the back of the boiler - but can put another to the side costing £260. But he warns us this may not solve the problem as it may be due to the water quality - so power flushing may be needed (£500-£800).

He reckons the Valliant could be 10 yrs old and feels we may be better to replace it with a new combo and suggests Worcester 28i which he will install for £1800 all in.

My questions are:

If we are only intending on living here for 2yrs is it worth the outlay? how likely are we to have ongoing problems with the valliant. At the moment it is working ok despite not showing any pressure. We have only spent about £300 in last 2yrs on service and repairs, which I dont consider to be too bad, but wouldn't want to shell out much more frequently.

Are there any other issues I should consider?
