Add an aquabooster to a gas water heater

hr

if you dual tank you will need a non ferrous circ pump between them. And you are adding additional standby loss.

Could you crank up the WH temperature and add a mixing valve? It would be a simple, inexpensive thing to try first, if you are close to adequate.

You should be able to calculate the tub size and run some numbers to see exactly how much HW they actually need. Large tubs generally need a "dump load" or add a small instantanous.

Someone I know

just had a new 50 gal. gas water heater installed in their home . Due to chimney height and doorway size limits , that's all that would fit . But ..... although the showers have plenty of hot water , he has an enormous jacuzzi tub that is used frequently , and the new heater just can't fill it up in one shot .

I was wondering if anyone has installed a storage tank connected to a gas water heater . And how did they go about piping the heater and tank .

Thanks in advance . Ron Jr.

Ron,

Check out HTP's site. I believe they have a diagram of a booster tank connected to an indirect. I think it will work with a regular tank too. Chris

Thanks Chris

I checked it out and they have the domestic hot of the indirect going right into the storage tank ( as part of the circulating loop ). The domestic hot of the indirect does not tee into the hot of the house . I was wondering if teeing in the hot of both tanks to go to the house would even out the use of hot water between both tanks ? Of course I'd recommend he throw on a good mixing valve too .

He told me

the aquastat is pretty much cranked to max . And this tub is BIG . He also has 4 baths and 2 kitchens . The mixing valve is a good idea , but I think he has his mind set on additional storage . Besides , from a wear and tear point of view , what's the longevity of a tank continously idling at 180 ( maybe ) , compared to 120 spread between 2 tanks ? Are standby losses increased when the temp of a tank is higher ? Thanks alot Hot Rod for your thoughts .

Ron,

I think HTP has got it right. Take the water from the stoage tank only. This way, the water going into the storage tank gets preheated, and will not run out on a high demand. I don't have the drawing here, but I believe there is an aquastat to circulate the water in the storage tank back through the supply/heated tank (and a check valve) if the storage tank drops.

Like Hotrod said, there has to be a non-ferrous pump, at a cost, and most definately a anti-scald mixer for it to work well.I would also fix an expansion tank into the fold as there will be a check between them also.

Geez, that's alot of stuff ain't it? Maybe they should have considered a horizontal tank or a couple of shorties tied together to meet their need? Chris

Ahhhhhh , now I understand

This is a friend of a friend , and I'm trying to get him on the right track . I've only seen this once before , but woe was me , I didn't take a close look at the piping . From what I know , there already is 2 furnaces and this tank on a smallish prefab chimney . So adding another gas heater might put it over the edge . But the way HTP shows it makes sense now . Thanks again Chris .
