Thanks J the G, why do I need both?

No it is definitely a 15i system boiler. So I presume that u just disconnect the old pump on the old vented system and the microswitch will turn the boiler on or the system boiler will sort out the start up itself

A couple of installers have mentioned this, So going from vented system to system boiler WB 15i, possibly. They tell me that they have to take a live from where the old pump would be removed to the new system boiler. I don't understand this as I would have thought that when the microswitch...

Thanks, I have another question regards system boilers, will start new thread

Thanks again, have heard of tundish, just remind me what it does, thought it was to do with vented HW cylinder

Thanks Ian Boiler would probably be a WB 12ri. If the pressure vessel was to go in the airing cupboard which is not on an outside wall then I presume that a copper pipe would have to run from the A/C to an outside wall for discharge? What is O/H. ? Thanks

I assume that a conventional boiler doesn't have a PRV so if you are going to pressurize the system where do u put the PRV , with the pressure vessel going in the airing cupboard? Is it a case of putting one in the pipework near the boiler or should it be near the pressure vessel or doesn't it...

Ok thanks, it will just go from the boiler down and connect to a soil pipe a couple of feet away.

Ok, those r all fair comments but has had good online reviews.........if that means anything. Also the quote has said that I may need a condensate pump, I know what the condensate pipe is but under what circumstances would u need a pump Thanks

Looks like the new way to give a boiler quote is by submitting images to the installer and he would then email a price. So , a picture of the old boiler, outside wall with existing flue and airing cupboard, if appropriate. Just wondered what the regulars thought about doing a quote this way? Thanks

Yes, I know that WB get a lot of flack on here and realise that prob not the best boiler but at least they will come and sort it if it does break down. Having said that I know a couple of people with a WB, never had any trouble.

That makes sense, suppose better to have someone who knows the boiler inside out. Than possibly only fitting his second one Thanks

Thanks for that, just that decent looking small co came round and is obviously pushing Vaillant which I don't want because of their lousy customer service and if you call them out under warranty u still have to give your credit card up front in case it's not a boiler problem.

Installers seem to have their preferred choice when it comes to fitting boilers. Some prefer fitting WB some Vaillant, etc. when questioned they will fit other brands ie Vaillant preferred will fit a WB. Is it better to stick with the boiler that the installer prefers simply because all his...

Thanks for that advice Hugh

Hugh Thanks, I,ll probably bring forward, if I have to shorten the plastic soil pipe going into the vertical soil pipe what's the best way to cut it? Dilallo Well at least the tiles matched the bog.

Hi All I am about to replace a WC and this old Ideal Standard has a unusual built in pan connector. ( swan neck style) Does the connector in image 3 look about the best to replace it with ? thanks

Wickes?

Not sure if u have a Bathstore near u but they do Denver at special of £60 and good reviews.

I am going thru the same dilemma myself, an ancient system going pressurised, I would go for open vented again but it is not possible because the f& e tank is no higher than the boiler. So I have no choice but take the risk. Chances are u will be ok but the risk is there and when u look at...
