What are the issues with tankless water heaters? I have heard them described
as having "issues", but I haven't read anything that describes what they are.
They are very popular where I live. Any info? Thank

Hello Wrenches,
Is there a good way to estimate the power that will be consumed for
electric water per person per day? We are estimating the amount of
power that will be used by an all electric duplex, and the water
