Laudromat

JackFre

laundromat systems. I have used a few as three Rinnai Integrity models (commercial) and as many as 8. All are doing very well and operating economically. How many machines and what poundage do you have. One of the advantages is that you store no water. Maximum flexibilty. I can help you with a sizing if you would like and can connect you with local people to assist in installation. www.rinnai.us.

Hot water for laundromat

Any recommendations for a system to make hot water for a laundromat? Tankless? Tank? Boiler with storage? Any ideas?

Constantin

Well, here is my thought process...

Laundries need a lot of hot water to keep the machines running. They also use enough of the stuff to potentially make condensing appliances pay for themselves in short order.

I'd consider the Munchkin VHW for larger applications as its 400kBTU/hr output is pretty impressive. A small buffer tank may help for the situations where a smaller load is calling for water.

An alternative is a highly-modulating gas boiler like the Trinity Ti400 in conjunction with a large HX indirect like a Phase III, ErgoMax, or TurboMax. This could be a very versatile solution.

But most importantly, I would look into the HX's offered by GFXTechnology to pre-warm the incoming water for the water heater with the wastewater going down the drain lines. There is a lot of energy to harvest there, and the GFX heat exchangers are reasonably priced.

Need hot water.............

Oil fired hot water heaters or any boiler with in-directs.
Alot depends on how any washers are used at one time. I would consult with washer man. spec's about how many gallons per machine x number of machines for a start.

Something to keep in mind Turbomax are sweet but depending on which state your from. The models available to me did not have an ASME rating. Its required for installs over 200k. Sounds to me like you would need at least that for a laundromat

Water heating

All of the laundromats I've ever done used Hamilton boilers with storage tanks. They are very similar to Lochinvar set-ups that I've also installed. I don't know where you can find info about the Hamilton boilers but I'm sure you can look to our brothers on the wall or just go off the wall to the northwest corner and get some help.

try RBI

RBI makes boilers and storage tanks for DHW

Consider...

Solar in your plans. A 30% tax credit and NO CAP on total expenditures. THat coupled with a good waste heat recovery systems will knock your gas bills for a loop, and increase the coinage that falls in your pocket.

As for auxilliary, consider the highest efficiency appliance you can get. Like a modulating condensing boiler with a good storage tank.

Before I was in the fuel oil business I owned a chain of laundromats. Most plumbers and heating people have no clue as to sizing a laundromat water heater. If you run out of hot water in a laundromat, it is a big problem. The 2 vendors I would recommend will help you size the units based on the # of washers and gallons per cycle Hamilton Engineering (http://www.hamiltonengineering.com/) and Natco ( www.nationalcombustion.com )

Good luck

hot water apparently not required

Just offer this product in your vending machines, undercut your competition, and omit the boiler altogether

it depends -

on your pounds per hour capacity. Our last project involved 2 - 400 pound, 2 - 200 pound and several smaller machines. A TEA direct fired (1,400,000 btuh with 1500 gallons storage @ 155 deg F)kept up nicely. TEA is out of Phoenix - and can size your project correctly. If there ever is an arguement for oversizing - this is it - running out of hot h2o is a real BIG problem.
