Boiler and tank sizing and questions

[Danlaundry]

Opening a new Laundromat by end of year, have equipment mix but can not decide on boiler and tank to use. Looked at Hamilton, RBI, Weben-Jarco and Raypak. Was going with 85% efficiency or 95%+ efficiency.


Questions for 95% plus efficient boilers:

95% cost 2 to 3 times more but do you make it up in savings? If so how long does it take?

Will 95% corrode sooner thus having to replace boiler and better off with 85%?

Have a recirculation pump to machines thus will have heat loss there. Does this diminish the 95% efficiency?


Questions for Tank:

Is concrete lined or glass lined better?


Sizing:

What size boiler and tank do you recommend?

This I have heard many answers to from 600,000 BTU to 1,000,000 BTU and 300 gallons to 600 gallons.

Here is my equipment mix all SQ:

7 - top
21 – 20lb
7 – 30lb
6 – 40lb
8 – 60lb
3 – 80lb

Thanks for your help

Is an Alliance dealer putting together that store? They been looking for "whales" in my part of town. Vegas slang..
lots of big iron. You got somewhere around 30k capita per sq mile?
Natco should be on your short list, a recirc pump does take away effc, you pump hot water thru cold lines, and loose. If you have a busy l'mat then you really do not need recirc because hot water will be in the lines all the time. If you get sold up the river on cash flow and how easy it is to make money in this biz than you need a recirculater for your bank account.

Most laundries do half their volume on weekends so you need to size your system for it's peak usage.
Hamilton Engineering has a program that you can imput all your info and they can size it for you.
The phone number is 800.968.5530. You can speak to their sales manager or go right to the top and talk to Jeff Deal the owner.

Pete,

If you have mostly High Efficiency machines you should really put in a recirculation pump. I have 30 Neptunes and 2" water lines and open 24/7. Without the recirculation pump it would take several hot washes before any hot water would get to the washers after a slow night. All of my hot water lines are insulated right down to the hose connections.

If you are not open 24/7 you could put the recirculation pump on a timer that turns on about 30 minutes before you open then shuts off an hour or so after you opened. This would ensure hot water for your first customers, but yet still be somewhat efficient.
