LPG gas flow rate stupid question

[bluemonkey]

this might sound stupid but i have a glow worm cxi24, the manual says the Maximum heating gas flow rate is kg/h 1.44

does this mean that if i have a 47kg gas bottle, it will last 33 hours (47kg/1.44kg/h=33hours)

as i am trying to work out why one cylinder has lasted me 4/5 days

 

[Dotty]

Sounds about right to me.

This is a very expensive way of doing it, I can't believe your gsr went along with it. Either.....

A. Get costs for a bulk storage tank.
B. Have your boiler ripped out and install oil.
C. Move.

 

[lame plumber]

yes if you have it on heating only continuously, and your heating system never reaches operating temp so your boiler wont modulate, if you leave the hot tsap on continuously it will use 1.98kg per hr, which is why I'd never install a boiler on lpg as its sooo expensive, moreso if you dont have a bulk tank. lpg cyl are ok for a cooker but you need to reconsider your heating options if you want to be able to survive in the long term.

or I could have said I agree with croppie, doh

cheers, i just moved to the property, rented will be out in 10 months, when contracted is up, the boiler is less than a week old, there is a bulk storage tank, but i couldnt afford the amount that the gas company wanted to delver me gas,

cheers for the answer, it is just so i know why i am using loads of gas

 

[Dotty]

Who hooked you up to the gas bottle?

 

[bluemonkey]

i bought the stuff, as i couldnt afford to get gas delivered as they wanted £600 miminum delivery and a 2 year contracts off me, didnt have the money at the time, but the 4 plumbers who my landlord had out not one said it would be expensive to run, compared to tank

 

[bluemonkey]

a 47 kg gas bottle holds 92 litres, and cost me £49, so works out at about 53p litres

avanti wanted 56p per litre

 

[Dotty]

That's not answering the question.

Who hooked it up?

 

[bluemonkey]

the plumber who fitted the boiler, is that what you mean

 

[Dotty]

Hopefully he tested the pipework. He should've advised you that you needed an automatic changeover regulator to take two bottles at the very least.

 

[bluemonkey]

i have 2 set up at the mo, got the gear to set up 4, just wanted to know why it use 1 in 4/5 days

all pipe work went in new, as the old stuff was condemed, there is about 1.5 m of gas pipe work at most

 

[lame plumber]

might be that its leaking away as well if there was no gas when the install was put in, as an air test isnt sufficient to check a new install

 

[bluemonkey]

there was gas, about 1/2 a tank when the boiler went in, just had a fresh tank delivered the day after, and switched over to the full tank, so i could judge how long it was going to last,

 

[Whyme]

I agree with croppie and lame.Bulk storage or your gonna have a problem for life...have you got upso and opso valves fitted..

 

[Dannypipe]

.have you got upso and opso valves fitted..

I doubt he's gonna know this tbh!

 

[bluemonkey]

no idea, so if i have large tank then i will use less gas,

 

[Whyme]

Thats the frightening part, like are they sited near drains is there a blast wall, are they near trees that drop leaves etc etc etc

 

[Dannypipe]

no idea, so if i have large tank then i will use less gas,

No, you'll use the same, but buying in bulk is cheaper.

 

[Whyme]

no idea, so if i have large tank then i will use less gas,

no youll probably use the same but it will be safe and above board...

 

[Whyme]

No, you'll use the same, but buying in bulk is cheaper.

you beat me again doh..

 

[bluemonkey]

so is it not safe and above board, i will try and upload a pic tomorrow if that helps

 

[bluemonkey]

i found that buying in bulk was more per litre that the 47 kg tanks, 56p to 53 p, but i can budget better with the 47 kg tanks

 

[Whyme]

bulks best pal becauase the storage cylinder will be well away from your house and you wont run out as fast, there are very specific reg for sitting lpg cylinders because of the potential of explosion and the gas being heaveir than air. supprised it was all ok'd on cylinders (being a house and not a caravan) tbh.

 

[dancinplumba]

Nothing wrong with running house on bottles, it's not dangerous 🙂

 

[Mike Jackson]

I think there's a bit too much scaremongering going on in this thread. The OP has said that the boiler and cylinder set up were installed by the same guy. Surely we can assume that he was gas safe unless otherwise told. All the OP wanted was to know if his gas consumption was about right and you've scared them half to death.

 

[Dannypipe]

I never said it was dangerous!

I just said bulk should be cheaper....but it sounds like it's not for the OP. The trouble with bulk tank is you often get tied in to having to get your gas from the tank supplier. So you can't shop around.

Steady on danny, no one said you did 🙂

 

[Dannypipe]

Good point!

Where do you by your gas from? Its minimum £70 a bottle in east anglia. 0.77p per litre.

Could easily get through a bottle a week with the cold weather we have been getting.

I didnt mean to scare anybody and never said his install was dangerouse, just letting him know of the importance of siting so he knows if his cylinders are fine even if the installer fitted them or not. again appologies for apparantly scaremongering..
