whats the price tag on these and how easy are they to install to an existing boiler setupCapeCoaler wrote:Indirect fired tank is the way to go!
Talk to any one who went from a coil in boiler to the indirect tank and you find a happy camper.
It acts as a zone in the boiler system.

NO BUTTS
Excellent suggestion -- sorry I missed it
No pink parts will be exposed in the appliance
your dishes will be cleaner - come out dryer and the family will be healthier!

Depends how long you like the shower and how much water one consumes doing a shower.
45-60 should do it, but your BTU output on boiler is your limitation.
The mixing valve also allows you to keep the hot water hot enough to prevent...

Sorry, I don't get the connection. How does hotter residential domestic water prevent Legionnaires' disease?CapeCoaler wrote: The mixing valve also allows you to keep the hot water hot enough to prevent...

Legionella organisms are readily found in natural aquatic bodies and some species have been recovered from soil. The organisms can survive in a wide range of conditions, including temperatures of 0 to 63o C, pH of 5.0 to 8.5, and dissolved oxygen concentrations of 0.2 to 15 ppm in water. Temperature is a critical determinant for Legionella proliferation. Colonization of hot water tanks is more likely if tank temperatures are between 40 and 50oC (104 to 122o F). Legionella and other microorganisms become attached to surfaces in an aquatic environment forming a biofilm. Legionella has been shown to attach to and colonize various materials found in water systems including plastics, rubber, and wood. Organic sediments, scale, and inorganic precipitates provide Legionella with a surface for attachment and a protective barrier. Interestingly, the growth of other environmental organisms is stimulated by organic sediment, which in turn leads to the formation of by-products that stimulate the growth of Legionella.
So if you store your hot water at 140 deg. F., you wil kill legionella.
Legionella is rarer in small DHW systems as the water turnover is usually very high.
Howvere, extra precaution for elderly people and people with immune defficiencies is recommended.

Water heater gets turned down to save energy and is in the sweet spot.
Lack of maintenance allows sediment build up.
Sediment allows growth.
Low volume spray head atomizes water in shower.
Inhaled water causes...

Well put.
Legionella loves to grow in faucet areators. Hence, this is a big problem for hospitals and nursing homes. Delivery to faucets can only be 110 degrees at these facilities by health code.
One manufacture makes a computerized mixing valve that will allow a "sterilization cycle" that facility maintenance can override and circulate 140 deg. to the faucets (of course with warning to the staff) to help keep them bacteria free.
I know how much these cost and will not be installing one in my home.
