Re: [GBlist] 100% efficient electric heat?

["Heidi Hirvonen" <heidi@sagedesign-interiors.com>]

I am a complete novice at all of this and have been struggling to keep up
and understand the deluge of emails that center around the tankless electric
hot water heater.

My husband and I just bought a house and we will need to replace the hot
water heater.  We are also hoping to use photovoltaic cells.  I am still
struggling with what some alternative choices to the traditional hot water
heater would be.  I thought that the tankless electric hot water heater was
starting to make sense if coupled with PV cells but now I'm not so sure!
Advice?  Guidance?  Choices?  Resources?

thanks much,

Heidi
