Gas Boiler Location

strife

Hi,

I’ve just recently bought a house and I’m in the process of renovating it, iv I need to decide on where I’m going to place my gas boiler and I was just wondering if anyone can tell what I need to take into account when deciding on a location?
Are there criteria to be met or can I just place it where is most convenient ?

Check the manual, there are different types of boilers for different situations.

Read the manuals, the main thing is that the outlet be placed somewhere that it won't create a nuisance or cause damage, because there is a lot of vapor.

You can do quite a long pipe run from the boiler to the outside wall nowadays, if you really need to. But it is best to put it on the outside wall.

To do this right, you need a dedicated circuit from the boiler to the hot tank, and it is good to keep this in mind when you are placing things.

Obviously you need to be near the 3/4 inch gas line and any existing central heating pipes.

.

You can but new regs from rgi state that all concealed extended flues must be accessible for inspection , so no nice tidy tight boxing to cover the flue allowed without access to it ,
Also remember the condense and safety valve discharge will have to get outside also .
Best idea would be to fit it to an external wall , saves a lot of hassell. , also if gas has to be upgraded it makes it easier to get to the boiler .

+1 to outside wall, used to be considered best practice (and all installers stuck to it) now we are reaping the 'benefits' of long concealed flue runs.

It's considered such a big issue, in the UK they have now made the regulation retrospective, and from 1st Jan 2013 any home that has one that hasn't any inspection hatches (at every joint) will be isolated!!!

70 apartments in Dublin were shut down for safety in one complex shortly before Christmas for defective concealed flues that we're recycling

Installers, remember to always FGA the air intake test point when available (even on your €45 service?)

Don't put it on a bedroom wall . . . .

My Mother in law had central heating fitted in the mid 90s courtesy of Board Gas, an older lady living on her own, they explained to her that the boiler had to be on the inside of an external wall (correct), and that in her case they would locate it on the bedroom wall (all boxed in of course), "ah sure you wont know its there missus, everybody in your estate has them in the bedroom thesedays" Sxteen years later and the thing is still a curse, the room is no longer the bedroom, its the boiler room/ laundry room. Under the stairs would have been the best option, but it would have involved more pipework, longer flue, and more hassle for the installers I suppose?

the modern condensor boilers are a lot quieter

antoinolachtnai

The older boilers - you couldn't really put an extended flue on them, because they didn't have a fan -.

DGOBS

Haha, the type without a fan (natural draught) were the quietest of all!

Mine made a bit of a roar anyway. The 'au naturel' Potterton Netaheat Profile 60 was a good bit noisier than the new Viessmann 100-w I got installed recently.

Got mine stuck in the attic last October. It's great,don't hear a thing(regardless of how quite modern ones are meant to be),it dosn't take space in a room,and no chance of any leak in a bedroom,etc.
Must get round to getting a co2 detector,but there's no real need.

Is the attic not above a room that a leak could pass into.
Why is there no need for a co2 detector

Rangi

It possibly could,but would have to pass through the plasterboard ceiling. I'm going to fit a detector or two anyway,just to be safe. For the sake of €25 each,I think it's worth it.

gdavis

is the boiler not above a bedroom?no leak possible???

anuprising

to clarify things ,what you want is a CO detector (carbon monoxide )
CO2 is carbon dioxide

As Anuprising says its a CO Detector you need....
I have installed quite a few in attics... just sorted my own (finally) and have my Worcester Bosch 18i System boiler (small house!) with DHW diverter kit in the attic. Flued out through the roof with a vertical flue and flashing. Gas line run across the attic to the boiler which is almost directly above the hot press so easy to split the system! Condensate out through the soffit down to soil stack and safety valve pipework beside it down to ground level. I also spoiled myself and installed Weather Compensating controls for the boiler with outside temperature sensor!! Fantastic bit of kit!!!:D

Never seen a netaheat natural draught?
Profile 60e? Was fanned flued (forced draught)
Profile 60, have no data on it, nor on Pottertons database (so assume it a 60e?)

Love those Viessmanns and Vialliant, super quiet

Yeah and i also typed co2 , and i fit carbon monoxide alarms must of been something in the air ............................... hopefuly not CO :eek:

I'm a Viessmann Junkie myself. There bringing out a new boiler in a few weeks. Me looking forward to it:)

DGOBS

I believe Baxi have a new offering, couldn't be anything other than an improvement from the Megaflo IMHO!

What problems have you had with the megaflo , ive never come across too many issues eith them , i think they are a pretty reliable boiler for someone whos on a budget and cant stretch to the likes of a veissman or a worcester.

DGOBS

Has installers put them on scaled systems and that heat exchanger really does not react well to scale (understood they system should have been cleaned)

Have had passing gas valves, failed pbcs, on that they decided it would be a good idea to have different pcbs on all models throughout the range...grrrrrr!!.....rather than the engineers being able to set the correct fan speeds via a pot, or a code plug like some other manufacturers, the water pressure switches on the first models were prone to airlocking (a first!)

And in general the warranty guys seem to always be busy, not a great sign
