[Greenbuilding] Nyle HPWH Update

[Paul Eldridge]

I received my Nova Scotia Power bill earlier today and our energy 
consumption during the most recent billing cycle is down 25 per cent 
even though our space heating demands this fall were 25 per cent higher.

Our new Nyle heat pump water heater certainly deserves at least some 
credit for this; by my accounting, it has cut our DHW costs in half, but 
perhaps the single largest share of savings can be attributed to the 
reduction in the runtime of our dehumidifier (the Nyle heats our water 
and, at the same time, dehumidifies our basement, thus providing two 
services for the price of one).

On an annualized basis, our total household consumption for our now 
all-electric home has fallen to 8,635 kWh/year and I fully expect that 
we'll get this below the 8,000 kWh mark in the coming months. With 
various efficiency improvements and by converting from fuel oil to 
electricity, we've cut our utility costs by over $7,000.00 a year.

Cheers,
Paul
