Product Highlights
Description
What makes the Alliance SL unique is the Hydrastone-lining. This one half inch lining protects the steel tank from the corrosive action of water. When the water first enters the tank, it is absorbed into the Hydrastone-lining permanently. This water loses its oxygen and becomes inert, non-corrosive water which then acts as a protective wall between the hot water and steel tank. This unique process and design makes Alliance SL water heaters a great choice for domestic hot water applications.

Q: Family of 4, 2 adults, 2 young daughters. next couple of years we will all be showering in the morning (2 bathrooms). will the 50 work or do i really need the 70?
Asked by michael from boston 13 years ago

If you have standard showers with a single shower head and a boiler with a domestic hot water priority control, even a 30 gallon indirect water heater would be adequate. I have two showers, but one is configured as a vertical spa with a large shower head and four body sprays for which an auxiliary pump is used to increase the water pressure to drive the five heads. I bought the 50 gallon water heater based on the better flow rate specifications and have never run out of hot water using both showers. A 50 gallon heater would be a better choice if your boiler does not have a domestic hot water priority control. In either case, a 70 gallon would be way-overkill. With a 70 gallon tank, you would also be heating up a larger volume of water unnecessarily. Domestic hot water priority control is the ability of the boiler to provide full attention to producing hot domestic water when demanded; while suspending heating of the hot water for home heat as long as there is a demand for domestic hot water (during the relatively short period that people would be taking a shower). When there is no longer a demand for domestic hot water, the boiler will return to heating hot water for home heat.
Yes. Fast recovery if water heated by a boiler. We have had 12 people using 4 showers never a problem. But we also heat with a boiler. Jim Sent from Jim Weaver's iPad3
You should be fine we have three adults and one children. The tank is plenty big.
We are a family of 6. We have never had an issue with running out of hot water. I would say the 50 is the way to go. Sent from my iPhone
Yes. We have 2 adults, and 4 kids (two teenagers and two little ones) and it keeps up. We sometimes have 2 showers at the same time or a shower and and a wash load along with the heaters in the winter and it keeps up just fine. The only time I’ve had to wait for hot water is when the furnace has turned off for some reason! (It was bigger than we thought, if you have a confined space to put it in it would be a good idea to check dimensions.)
Q: I am thinking of installing this unit to replace a traditional 50 gal water heater. After reading the other questions and answers, and reviews, I am wondering if I need a new 50 gal unit or if a smaller one will work fine. I live in a small town home, only 1 bath. There are only 3 of us, but if I sell someday, there of course could be more people living here.

I have the 50 and even with 12 house guests and 4 full baths it has never run out of hot water. Your boiler roaches the water with 180 degree water. Conclusion, I would think a smaller tank would be more then sufficient. Jim Sent from Jim Weaver's iPad
I have this very same unit and it is great. There are 3 of us and I have an outdoor furnace which heats this unit. This is probably the best solution to hot water heating I've ever seen. We never need to worry about lack of hot water. I personally would not go to a smaller unit unless space is an issue. This unit should not cost any extra to operate than a smaller one since it holds heat very well.
I'd go with the 50. We are three here as well and it is perfect. Scott Feero
Yah I think the smaller one would be fine but I can’t say for sure since I have a 50 gallon. We have 3 baths and 6 people and an endless hot water supply. Someone with the smaller size would be a better resource.
The smaller unit should be fine for your 1 bathroom townhome. Make sure your boiler is capable of providing enough output and water tank is on Priority Zone. Also note the weight of the unit. Very heavy.

Q: I have a Burnham ES2-4. Will I be able to install an indirect water heater on this unit?
Asked by scoester 14 years ago

Verified Reply- PexSupply StaffYes, you can connect an indirect water heater to an ES2 boiler.
Yes. You'll need to have an additional zone added to your heating system dedicated to circulating boiler water through the heat exchanger in the indirect water heater.
Yes, it is just another loop off the boiler.
My indirect hot water heater is to the furnace a second heating zone, so the controller on your furnace must allow two zones. I am not a plumber, but I'm pretty sure your can replace the controller if necessary.
Yes, you can add an indirect water heater to this unit. You will need to add a zone for the water heater and if you use the burnham hydrostone lined indirect water heater you'll want to have that zoned with a pump as the pressure drop across the coil is significant. If your heating system is currently zoned with zone valves it will be a decent project to reconfigure for the additional zone. You'll also want priority for the indirect water heater. John White Process Engineer
i use a pvg4 boiler with 3 different indirect water heaters 1 for my potable water 1 for my breezeway heat and al50sl indirect water heater just for my house infloor heat runs. i would recemend indirect heaters for boiler systems . i found that just useing a boiler with a mixing valve into the floor runs are not as good as useing a idirect water heater to do the 2000feet of pex runs . i have a 2800 squ foot house and with an 80 dollar gas bill for heat and also potable hot water. im very happy with my puchase
