Tell me it was worth it.

Thany-you for your reply. Do you thing that I need a tempering tank?

Found this old thread about hot water coils, custom made coils and using them for heating baseboard heat.

Good reading, so I'm bumping it to the top.

i'm bumping it again......thinking about installing a coil in my stove going to the water heater and a 4' baseboard in the bathroom whick is right next to the water heater
heres my shopping list so far:
24" hilkoil kit
grundfos UPS15-58FC
does the whole run have to be made in copper? can i use cpvc or pex?

How long is the run and how much would u save? I would use copper if it's in the budget.

This has been a very interesting thread for me as it has made me stop and re-think my plans. I had a coil installed in my Koker but have yet to hook it up. My current electric water heater is almost 18 years old and I am going to be replacing it soon. I've already secured an estimate to replace the water heater and plumb the coil, tempering valve,etc. But, I never considered a tempering tank. Before I commit to tying in the coil directly to my water heater, are there advantages to using a tempering tank. I know that if the pressure relief valve blows on my planned setup, water will collect in a catch pan and then drain into my sump crock. I like the idea of being able to route this blowoff for a useful purpose.....or even using some of the heated water for another heating zone?

thanks

With such a smal coil a tempering tank would be useless. Plumb the coil into your tank with a circulator. Unless u have small children u don't need the tempering valve.
