Indirect Hotwater Heater

Joe Brix

why you getting rid of it? Weil's indirects, which are relabeled Triangle Tube's Phase III tanks are the best value, IMO. What about a booster tank and keep the tankless coil if it's still OK. Heat transfer products has some nice storage tanks.

All,

My heating setup currently consists of a Weil-McLain WTGO 4 section with an electric hot water heater plumbed off of the tankless as a storage tank. THe hot water that is being made is awesome. My concern is with the storage tank. What I want to do is plumb in a indirect hotwater heater, on a seperate zone, and eliminate the old electric hot water tank. Could I get some suggestions as to which indirect would be the best in my setup? I'm looking for something in the 40 - 60 gal range.

I expect you will see a change in your electric bill when you change over. Look for an indirect that loses no more than one degree per hour. You can find them with only one half a degree per hour heat loss.

I don't want to get rid of the tankless if I can help it. It's the water heater that is being used for storage that concerns me. It's getting old and I want to be ready to change it. I will look into heat transfer, thamks. Just so everyone knows, the electric water heater is just a storage tank with a circulator on it. It is not being powered by 220 or 110 to create hot water. Any other suggestions?

Why not just replace the Aquabooster tank? Tanks made for this purpose are available and have a longer service life than electric water heater tanks{no elements to leak} and as you already know the output can't be faulted

A booster tank

would be just like your WH, just in stainless steel. Should last longer. You have a bronze pump now circulating the DHW through the coil, right? If it's OK, you can save the cost of replacing it. If the tankless coil was leaking and had to be pulled, I'd consider an indirect instead. A straight booster tank swap should cost less then an indirect.

I guess this is what I am looking to do. But lets say the tankless coil down the road stops working the way it is now. Can the booster tank be used the same way as an indirect water heater tank? What is the cost difference between a booster and an indirect?

Thanks Joe

The only unknow is the tankless coil. Yes, I have the circulator you mentioned, but cost is not the driving issue here. Reliabilty is. I want to add something that I don't have to touch for 10 - 15 yrs. The tankless is about 7 - 8 yrs old. I don't want to add the booster then add the indirect, or something else, 5yrs later.
