Outside gas boilers ?? ( Replacing air source).

[Smellydog]

Our old air source is err getting very old and will pack up no doubt soon.
Anyway I was wondering about replacement consisting of fitting an external gas boiler and using 45kg LPG.
In the interest of saving the planet by releasing much needed co2 how feasible is it to use the current system in the house plumbing for the current air source system?
I'm not sure if it's possible for a gas boiler to simply keep a hot tank hot like our air source does now, we don't use the radiator side of the system content with the multi stoves etc.
Could the air source go away and a gas unit drop directly in its place outside?
Thanks in advance for any information.

Im not a plumber, so ud be better asking a decent plumber ( or a few)

I couldnae see it being a problem for a LPG to heat up a water tank.
Does ur hot water come off the tank?
If so u likely need to change some plumbing if u get a combi boiler.

Only thing i d say is search some boiler makers like worcester, etc im not sure if u get an external LPG boiler.
Ive never seen or heard off 1, which doesnae mean u dont get 1.
Usually when ive seen an external boiler its heating oil.
But like i say u really want to speak to a rural plumber

I've seen gas boilers fitted outside on campsites running showers, I think they use them in livery yards too. They're basic but cheap. Trying to get a plumber to fit one might be a challenge though!

Thanks lads.
Yeah I have a hot water tank.
I wouldn't really want a combi I think but something to just heat the tank and hold it's temperature until demand and replace.

Grant boilers are the best at the moment.
Email Phil Wilson Plumbing & Electrical, he's based in Norfolk, ask him if it's doable. He's a clever F u ker...

Whats an airsource?

Whats an airsource?

It’s a fridge in reverse basically. But as per the OP I work on plenty of houses using LPG as I live in a rural area and it’s Oil or bottle gas. They heat the house and water the same. And most are now external boilers. Same as internal but in a nice green insulated case. Take up about the same amount of space ans Air source.

Had a Grant oil boiler fitted outside in July, Eco version with a 10 year guarantee. Much more efficient; we even thought we had a problem with the signal from the Watchman oil sensor as the oil level never seemed to fall since it had been commissioned. Even though outside it is much quieter than the old Worcester Bosch it replaced. Freed up a lot of space in the utility room, now taken up by the solar batteries.

Best be quick Nathan, it’s coming Southward. Just awaiting the Tesco van, already had to clear the paving slabs! Started with a flake or two at noon, got going at dusk (1620 here, ‘beyond the Wall’)

Do away with the hot water tank and just run a Califont of bottles, very common here.

I thought LPG went out of fashion years ago, as it costs way more than oil.

Obviously mains gas is always the cheapest and best option if you have it

Not sure about the UK, but here it depends on when you buy it.

Summer time is the best time to fill the tank (when it's way cheaper), and just top off, just before winter rolls in, so you have enough to ride out the full winter season at summer prices without a winter refill.

If I recall some studies years back, LPG was initially very cheap (perhaps 20 years ago), but more recently it worked out to be 2-4 X more expensive than oil.

I have had oil heating for maybe 15 years, temperatures down to -20C. Very reliable.

Well bloody hell!
The air source has packed up this very day!

Just set the 7 day timer for three burst a day on the immersion heater, that'll be interesting!

Next issue will be freezing of the unit outside....

Very tempted to have it all ripped out and a new stove with back boiler levered in.

I completely renovated my house a few years back.
Tried very hard to plumb back boiler into a log burner.
But just so many cons it wasnt worth it.

Biggest 1 for me being rural in an area prone to power cuts was if no power i couldnt use my log burner as pump would not work.
I also gained an extra room by not needing the hot water tank.

But if u had a 2 storey house with rads it might make more sense
Every house will be different and depend how easy it is to plumb.
