[Greenbuilding] Opinions on electric tankless HW heaters?

[Nick Pyner]

Indeed. Peace of mind and social responsibility are just as important as
environmental sensitivity. (So make sure your rainwater tank is properly
mosquito-proofed too!!)

I take on board your comment about the height of the element but I have no
idea just how high they are normally located. I assumed they would be as low
as possible. I have just given my neighbour a bare copper tank and I know
the element wasn't right at the bottom. I will get him to measure it.

I am right now in the process of installing a small electric storage heater
with its own kWh meter. It has a 65C thermostat. It probably won't be very
fair but I will see how it compares to yours!

Hi Nick,

Your concerns with regards to Legionella are certainly not lost on me.  As
noted, I keep our water heater at 72?C knowing full well that the
temperature at the bottom of the cylinder is several degrees cooler.  I love
saving energy, in particular electricity, but I'm not going to put our good
health at risk.  At just under 5.0 kWh per day, I don't consider our water
heating demands out of line, but then there are just the two of us and we're
both pretty frugal by nature.

Cheers,
Paul
