no you are better off using a site like gawminer.com buy the gear and let them host it. I think you avoid the vat.
It's funny, I've never considered such a hosted service, and I just took a closer look, but the numbers don't add up.
Buying a S3 from Bitmaintech is ~ 390 USD, at GAW Miners it's 499.95 USD. Their hosting service is 0.9 USD a day after a free month versus 1.22 USD on engery costs for a day of running the S3 here at my place (calculated with 340W instead of the indicated 366W on the GAW Miner S3 product page). So the two prices including running costs reach equilibrium after ~ 256 days at a total of around 702 USD, which is way beyond the point to which you can make a profit. That calculation is done without VAT because it would not apply to my (one of the advantages having a company at hands), with our VAT of 20% for the hardware on import and on energy the picture would be different of course.
Calculated the other way around: The hosting service of GAW Miners for 0.9 USD equals a price of 0.11 USD per kWh. Combine that with the premium on the hardware purchase and you will never reach ROI anyway.
However you turn it, it will be a loss.
Your calculations are not including the fact residential electric has utility, fees, taxes. You may be charged for many things so what is $1.22/day in energy costs for you might add an additional $30 of taxes and fees.
Hosted units are flat rate. You can host 10 S3 for $0.90/day and $270 month for 10 of them. Your home may run 10 S3 for $1.22/day and $366 month but you might end up seeing $50-100+ extra for fees and taxes after energy cost.

You are right, especially at home you will barely see ROI, those energy costs won't help when the difficulty goes up you earn less and your margins are pressed against the wall. However you turn it, it will be a loss.
Do any of you here know why the queue on the config is set so high? Is there a big gain from setting it to a lower number or why did they program 4096 as the queue. The discarded amounts are so high...
I can't be the only one can I? I saw all my units with the same high queue, I don't know what to make of it!
