gas line from hosue to workshop

[dazzler]

Doesnt help none but I just love a wood fire in the shed.

Helps cover up mistakes as well.

for example we are on bottled gas here and I could not have the gas bottles alongside my outdoor split system airconditoner that I purposely poured a slab to accomodate the bottles, as it was within the point of ignition allowable range i think but might be corrected is 1.2 mtrs but inside where you have the gas bayonets in the house you can have a power point right next to them and there is no restrictions what is the go there also,over the years i installed mains power to houses and the gas fella puts his pipe in the same trench and the gas meter is located directly below the switchboard? Is there any gasfitters out there who can clarify the regulations on this

I had thought of that, if someone can point me to an electric heater that is as cheap (or cheaper) to run than a gas heater ( shed is about 35 square meters).

I also thought of running hot water from the existing water heater, but concerned about the amount of heat loss for about 25 meters of pipe.

Mate you would be better off using a little 25litre plug in job that goes under the sink, assuming you only want it for washing up. Running gas that far for a space heater and HWS you may have to increase the size of the WHOLE gas service from the meter, and may have to increase the size of the meter itself. As it sounds you may have the original gas service working flat out already, it all depends on available pressure, lineal lenght of pipework and megajoule ratings of all fixtures. Hope this has been a help.

Ignition source not within 1500mm of exchange bottles and 3500mm for in-situ fill bottles
No dramas under a switch board but it states that you need a minimum clearance above it for seviceing, 500mm I think and as long as it meets venting requirements.
In a trench a gas pipe needs 100mm clearance from an electrical conduit provided the conduit is marked along its lenght otherwise its 300mm.
As far as bayonet fittings go common sense prevails here, the question had me stumped but I couldnt find anything in the "Bible". Though most modern heaters need power anyhow so you wouldnt place a bayonet fitting on the opposite side of the room to the GPO.

mate ya only kiddin me about using poly pipe to carry the power arnt ya? you are going to use heavy duty conduit correct!

nope, I ran the poly with orange conduit inside that, for the power to the new shed I will be using just the orange conduit. (poly is about 2" diameter, wall thickness is about 5mm)

gas meter was replaced about 8 years ago, the *metal pipe running from that is a little over 1" OD, the heater, HWS & oven / cooktop are connected via 1/2" copper

the origianl 90-4star rated HWS (and I mean origianl, as in almost 30 years old) was replaced with a 135lt about 9 years ago, the -5star central heating unit is being replaced with a 4 or 5 star unit this year.

I will check the ratings of the current heating unit, we did notice a drop in the gas bill after the new HWS went in. The meter should have a rating on it somewhere as well, right ?

Thanks for the reply


*looks like 1" 1/4 OD gal water pipe to my untrained eye

cheers wonderplumb your a wealth of information

[wonderplumb]

Yeah the meter itself will have a rating in cubic metres p/h and the regulator will have and outlet pressure written on it or on a sticker, usually 1.38kPa or 2.75kPa. Without looking at the pipe it sounds like it would be either 3/4nb or 1"nb gal. If it is 1" gal you may be ok, but as I understand VIC has some pretty tough rules on gas, we all follow the same australian standard but each state has a governing body which has its own standards, and therefore overrides the AS5601. I also know that VIC is pretty critical on where gas space heaters are placed, I dont know the size of your shed but it may be too small an area. Im only throwing suggestions out here mate to give you a heads up but please consult your local gasfitter, as I cant quote victorian specific rules.
