anti scald and tempering valves

Terry_2

I have a customer that I'm hooking up an outside wood boiler with a domestic coil. He wants me to put a temperature regulating valve on it so the water can be set at 120-140 degrees. I've used tempering valves on oil boilers that were used at the boiler but this is going to be 100' from the boiler. I was looking at a catalog with anti-scald valves and they had 2 kinds one for point of source and the other for point of use. Would this be what I want? Do you guys have any suggestions and what do you recommend? Thanks

Look in to Sparco. I couldn't find a web site but heres a tel. number 401-738-4290 Warwick, Rhode Island. I think they make the very best tempering valve.

Good Luck

Tempering Valves

I haven't had a lot of luck with Sparco especially with weird water conditions. I've used the Watts 70a valve with good success. They have two ranges, one I thing is 80 to 120 degrees and the other is 120 to 160 which is the one I recommend.

100'

The '93 BOCA plumbing code that we use here in NH says that if your water heater is 100' or more from the furthest fixture that a recirc pump is required (w/ a timer and a switch). Could you hook that line from the boiler into a Booster tank and then run a mixing valve/ tempering valve off the hot side of the tank.Point of source type.I have used the Taco valve, and Watts 70A. I prefer the Sparco.
Just a few thoughts..Kevin C.Ps. Just make sure that the recirc. line is run in copper not PEX. Pex does not like this application esp,. w/ clorinated water.

Hard water conditions

will be tough on any valve that has to continually move or adjust. Seems either you have to treat (fix) the water or plan on continual maintenance.

I, too, had problems with the earlier versions of the Sparco. They have made some good improvements with the addition of a teflon, I believe, coated components. The chrome finish inside the older version bodies seemed to wear away causing the spool to stick.

They also offer union connections for quick and easy change out now.
Take the old one back to the shop for a delime, or rebuild cartridge treatment. I like to install ball valves at all three ports for quick maintenance and repairs.

I thought Honeywell bought out Sparco? Maybe just certain products?

Pex and domestic water

Don't use Pex? I thought most of the Pex guys have been selling non barrier tube for domestic for years?
I know areas in south central PA where the battery acid they call water has forced them to outlaw copper in new plumbing and most of the guyshave switched to PEx. Is there something we need to know about?
Thanks,
Roy

Pex

What I was reffering to is Pex s' use in a RE-Circ line. ie a Taco 006 Bronze. The constant action con cause the pex to break down.Most manufactuers spefically say not to do so. It is especially bad in clorinated/public water.
HR had mentioned this a ways back.
