Can someone check that I am reading a commercial gas meter correctly.

 

2 photos taken 15 minutes apart.

 

Am I right that is 5 cubic m of gas, which will cost something like £1.50? I don't mind being out by a third in my guestimate, but I do not want to be out by 10x.

 

I am asking because we have a BFO gas blower in our gym unit - they divided 20k sqft into 3 and as the first occupant we got to choose and had the one with the existing heating system - and I don't want to find I calculated it wrongly in 2-3 months' time. We just want to take it from frozenballs to training temperature in the morning 1st thing through the winter.

 

 

 

 

Cheers

Thats a reading of 4.6 cubic metres so it’s correct on the calculation. The blown air units are pretty hefty - a 200kw fan unit in a single medium sized industrial unit wouldn’t be surprising so it’s about right. 

 

Bear in mind these units and the heating systems are designed to keep them above 12-14c, not  18-20c. There will be no floor insulation, very little in the walls and roof so you’re trying to heat a very big volume that is losing a lot of what you pump into it. 

IR is better for big open spaces- heats you, not the air.

Thanks Peter - so about 10p per minute whilst it is running. Good enough to know we won't get an umpteen thousand £££ bill without warning. Thanks.

Yep - we need to think it through carefully.

 

Will add a couple of piccies.

This is the whole thing pre-refurb. Length is about 55m, and width a little under 30m. Eaves height is about 4.5m, and apex about 9m.

 

 

Here is the unit during refurb showing the gas heater. Our unit is about 18m x 30m, with a couple of extra spaces on the end - a former dye house and a store.

 

 

When we ran a test yesterday it put the temperature up by about 6-7 Celsius in 15 minutes. A previous test had people commenting on being too warm whilst exercising. Suspect our members are quite inured, however.

 

I'll see if I can find a more recent one with the fit out more complete.

 

It is nice in summer that it keeps fairly cool, as we have double doors one end and a roller shutter the other for a through draft.

 

We need to do a bit of playing around - I think in winter on cold days it will want a whump in the morning to get the chill off, and then perhaps another in the afternoon after the afternoon lull. I think we may get some Far-Infrared type heating for the more sedentary areas such as warmup / yoga stretching / childrens area and reception.

 

Time to collect some data and ask for some feedback from members and people on the current pre-Christmas promotion.
