Dilema - where to put boiler - indoors or out

[furryfriends57]

Hi DIY experts
You all seems to have great advice so wonder can I ask for advice on where to our boiler. We are building a new house and the options are to put the boiler in the garage and use a zero heat loss pipe to bring across the heat or put the boiler in the untility room and pipe to heating oil in. The garage option is the most expensive but we are worried about the long term degeneration of the pipe and that we may lose heat. If anyone has experience of either or any advice would appreciate it.
Thanks, FF

Will your heating controls be on the boiler ? If so i'd go for utility room. We have a combi boiler in the garage and it's a pain in the arse going out to flick the heating on/off in this erratic weather.

Thanks for your reply Blacktea. Good point but we will have the heating controls will be indoors so we can switch it on and off remotely. Means we will have two pipes (one hot water and one cold water) and a cable running from the house to the garage. We just dont know if its worth the extra expense of all the extra work.

Ours is in the coal shed and I would rather have it indoors to save the heat lost from the connecting pipework.

I don't suppose ours has a proper zero heat loss pipe (the system was clearly done on the cheap like so much of the DIY previous owners have done here), but the line from boiler to house is always frost-free.

We are considering having a porch/utility extension and will put a new boiler in there if we do.

Put it indoors. If it is in an unheated place like a shed or garage, it will be at risk of freezing, so it will turn itself on and warm the pipes at intervals during cold weather, especially at night. If the electricity is ever turned off or fails in winter for some reason it will freeze and burst anyway.

Zero-loss pipe sounds like a perpetual motion machine to me. No such thing. Insulation slows down the rate of heat loss but it will never be zero.

Modern boilers can be very small if that's what you're thinking of.

If it is a combi, then when you turn on a hot tap, you will have to wait for hot water to travel all the way from the boiler to the tap. This may be quite tiresome if it is a long pipe.

Thanks for all the replies and its good to see consensus is for indoors. For any of you with indoor boilers is there any smell of oil where the boiler is placed. Thats a concern we have with DD in the house. Am assuming modern boilers dont suffer from such afflictions.
Piglet Id have to agree with you re zero heat loss pipe, I too find it hard to believe its 100% heat loss forever.
Abzs have heard a few stories like yours, which is no consolation, where the insulation isn't good and you can see the line in the snow / frost where the heat is being lost. What a pain and can understand why you want it moved.
Oh the joys of all these decisions, would love a new warm house but am so afraid we will end up with something we wont be happy with cause everyone seems to advise differently and dilemma is who to believe - thank heavens for MNers who are impartial

I don't think our boiler has an oily smell. I surveyed a house last week that had an older oil boiler in the kitchen (old school behemoth, size of a washing machine) and didn't notice any smell there either. I would think there shouldn't be, unless there is a problem and heating oil worries me less than gas in that regard.

CatB loves the frost free path that leads almost exactly to the cat flap in the coal shed door. She has a spot on the shelf above the boiler top taking advantage of the frost setting that fires the boiler when temperature drops.
