Re: [GBlist] tankless water heaters

[Ron Cascio <rcascio@beachin.net>]

I remember reading in Environmental Building News some time back about Rinnai
tankless water heaters and a new direct vent model which was supposed to come
out soon. I too plan to use a tankless water heater soon on our own house and
followed up to see is it is out yet. Here is an E-Mail I just recieved from them
this morning.

Mr. Cascio,

Rinnai presently has a direct vent model available. It is a model number
REU2402-FFU. At the end of January, Rinnai will be offering another
internal unit, model number REU2532-FFU. Please contact Dan Driscoll at
(800)621-9419, ext.244 for more information and specs on this product.

Thanks for your intereast in the Rinnai product line. If I can be of any
further assistance, please contact me at (800)621-9419,ext. 209.

Sincerely,
Gary Williams
