Thanks Jay. Now that electricity & gas costs are skyrocketing, I'm being kept very busy supplying folk with our very energy efficient tankless water heaters. Hello Mr. or Ms. Bent Nail. Is the heater just for the sink, or for a shower etc' too? I have a couple that will work fine for you: One will need to be drained, the other has built-in freeze protection. We also have wonderful gas tankless water heaters. Please call me at 1 800 851 9891, or e-mail me and I'll send you some info. Or maybe I'll just send it to your e-mail address, if that's ok. Isn't the internet wonderful! Regards to all, from Brian.
