Eko has landed :)----- questions though

[CANUCK GLAZIER]

Hey boilers!!

I picked up my eko25 the past weekend and maneuvered it into the house with the use of ski-doo dolies, imagine that a canuck with ski-doo dolies

Anyway I took Nofossil's advice and made room for water storage, wood tank with epdm liner. It should hold aprox. 600 gl.

My question is the dip tubes for the storage---- is there a particular height to place them and location in tank? ie. side to side or end to end. My tank's interior size is 35.5w x 84 l x 48 h. How much room do i allow for expansion?

I'll be insulating and constructing the lid today, I am waiting for chimney parts to arrive . I'll have to wait till I'm home again from working out of town to complete that.

I'd love to post some pics of my "green machine" but alas I'm on dialup and the whole upload would likely take the longer than my install

Love the cool nights, cant wait to finish the install.

I'll have lots of questions regarding easy control hookups later.

thanks in advance for helping guys!!

Pretty exciting time - I remember when mine showed up.

Don't want to throw cold water on your party, but if it's an open tank, I hope you're using a flat plate heat exchanger. Circulating water from an open tank through your boiler will lead to premature corrosion due to the continual supply of dissolved oxygen. There are things you can do to reduce the threat, but best is to keep unpressurized storage water separate from pressurized boiler water. I use copper coils submerged in the tank, but at the current cost of copper a flat plate heat exchanger and a circulator looks like a better deal.

If you go this route, you want the incoming water to cause as little mixing and turbulence as possible. You want to maintain storage stratification.

Hey Nofossil,

Thanks for responding. I forgot to mention that yes I am going to use a flat plat exchanger. In all the excitement I plum forgot

Anyway I have to leave after this weekend and won't be back for another 3 weeks. Good news is all the chimney parts will be in and that will be the only outside work for the install. Then all the fun stuff.

What I was wondering Nofossil is based now on unpressurized storage and my current dhw(oil fired)
I know its alot of work for you but could you sketch a basic set-up of pumps, controls and stats and mixing valves for me as I will be assisting a plumber friend who has never hooked something like this up before. He kinda knows what I want but any of your expertise would be greatly appreciated.

Thank you again,

Your northern boiler buddy

You can take a look at what I'm doing - the schematic is on my website, in my signature below. I have a simpler example using pressurized storage in a sticky at the top of this forum section. With a little imagination, I think you can modify one or both to suit your needs.
