Gas Boiler & Hot Water Cylinder Location

shaneh

Hi all,
we renovating a house and making switch from oil to gas. Quick question has popped up re the location of gas bolier and water cylinder.

Architect recommends we put these together in the garage. Plumber recommends we put these together in a hot press on the first floor. The main reason being that if down stairs in garage if it will take longer for hot water to get to shower & bathroom upstairs. I haven't talked to the plumber yet, will do so on Thursday but just wanted to get initial thoughts on this.

Just some concerns on my side that if we put these upstairs
1) Is it dangerous to have a gas boiler in a hot press that will also be storing linens.
2) Is it also dangerous in terms of potential fumes?
3) Cost. Does pipe to Boiler have to be run all the way by Bord Gais up to second floor?
4) Noise. Hot press will be right beside bedroom so have a concern re noise as well.

Cheers
Shane

1. No but you will continuously burn out the boiler PCB from overheating. I would put the boiler in the garage (balanced flue, of course) & the HW cylinder in the hot press unless you are pressurising the HW circuit.
2. No.
3. No, but by your RGI.
4. Not really. HE boilers are generally fairly quiet.

Thanks Shane. I'm meeting builder tomorrow so will let you know how discussion goes.

If you do decide on together in the hot press, gas regulations state they must be separated into two compartments, as combustable material are not to be stored in with the gas boiler (i.e.. clothes)

Fair point Shane makes with the PCB, but I have plenty on my year schedule that are done this way, and haven't had any PCB issues.

The garage is best for the boiler, easier to maintain there too.

If I where doing it I would put the lot in the garage especially if it was next to the house, including the cold water storage tank. I would then pressurize everything so you would have great pressure all over the house.

If the garage was next to the house you could then easily split the heating into upstairs and down stairs and put weather compensation onto it.

Bear in mind with putting it in the garage, if you ever extend the living space into the garage, it'll be something which will have to move...

Or have a designated plant room in the garage within a foot print and leave the rest for conversion.

The Boiler will always be safer in the Garage. Why not put a Combi Gas Boiler in the Garage. Positioned backed onto the Kitchen and close to the Bathroom no long runs to worry about. Then no need for a Cylinder in the Hot Press. Just put a small Rad in the Hot Press, You then have the best of all situations with more storage space in the hot press.

A lot more considerations than that for a combi, I'm afraid. Combi's are very useful animals but they have their limitations & are not suitable for many installations.

Hi all,
got to meet up with the builder on Friday to discuss with him. The background for not putting the boiler in the garage is actually due to an issue with the garage itself, rather than the pros/cons of a bolier location. The roof on the garage is asbetos so obviously nobody wants to cut into it for the bolier chimney flue. There's no external wall area on the garage either that we can use. We have a bit of a small alcove in the downstairs hallway so we're gonna put the boiler in there and run the flue straight out to the front wall kinda above and to the side of the front door. Not the ideal place to put it but it's the best that can be done. Hot water cylinder and water pump for shower, we'll leave in hotpress.

Not going with a combi boiler as we'll be running kitchen, bathroom and 2 future bathrooms off the water system.

Thanks
Shane

Flue above front door will look terrible. Surely, there would be a better place! Perhaps in the kitchen & cover with a cupboard.
