David and I decided to go with Myson hydronic radiators, fed by solar hot water using the Phoenix system, with a gas back-up if necessary. The white Myson radiator above is made in France and is the LST style -- that is, low surface temperature of 100 degrees F. Better for kid's inquiring fingers than the warmer models.

Below is their standard color in white, but you can do custom colors and finishes too, as we are presently doing.
Myson also makes this bench (below), which is a great option if you are short on space in your mudroom or entry hall as we are.
Another great way to heat bathrooms is with a Myson hydronic towel warmer. Comes in many finishes, including the one below.
We just got the radiator back from the auto body place we used - painted the white radiator a brown/bronzey color that works with our cocoa walls in our bedroom. We're thrilled with the result.
