Sizing.

All heating systems are designed for the coldest day of the year + some margin. It's a liability thing. You want to make sure your heater can keep you comfortable even when it's -20 outside for 2 hours at night that one day in January.

If you size a home or business hashrate heating system with those rules, then you end up buying 10x amount of miners - but only use those 10 on that one cold day. 90+% of the year, you have ASICs that are never running. Big mistake when the miners themselves are more expensive than regular heating systems.

So we size with a different rule at Exergy - "base load sizing". Effectively, we pick the number of miners you need to cover the "majority" of your heating needs - resulting in the miner running as close to full power as much as possible. This stacks you the most sats from that machine and gets you the best bang for buck / ROI.

On the extra cold days, the traditional heating system kicks on to help the miner out.

Think of it like a hybrid car. The Hashrate heater is the electric motor/battery in the car. were sizing it optimally to get you best gas mileage. Not turn a gas car into an electric car.
