TANK TYPE WATER HEATER INDIRECT WITH DOMESTIC PRIORITY

I can not recommend many online suppliers but some of the ones I can are:
www.pextubingstore.com  and www.bostonheatingsupply.com 
These are people I have worked with, they sell quality products, for the best prices and stand behind what they sell.
They will also give you 5% off on purchases if you use code Fred Seton for a reference.

Using a design, with loops up to 500' of 1/2" pex with a single manifold next to the heater in the mechanical area will heat very large homes. This design allows as many thermostat controlled zones as you need. It eliminates using a pump for each thermostat and manifolds scattered throughout the home. 

USING A SINGLE PUMP AND ZONE VALVES FOR EACH ZONE
IS THE SIMPLEST AND MOST EFFICIENT SYSTEM.

ALL PLUMBING BETWEEN HEATER AND HEAT EXCHANGER MUST BE PEX OR COPPER OR BRASS
