Hi Guys. So with the introduction of the new heat pump water heaters I'm having a problem figuring out which is the best to use. I have 1 bathroom, 1 dish washer and 2 people living in the house. Is there any website or study comparing the efficiency and cost of the 3? i also know this depends on how much water we're using... I don't think we're too horrible. I have a 1 gallon per minute shower head and I'm not sure what the dishwasher uses. We shower together every other day for 15 minutes so that saves on water also
