Is an ODR really helpfull

Tony_55

I have a peerless WV3 boiler with Honeywell aquastat and 3 Honeywell 8043E1012 zone valves and no tank - thinking of putting in an electric 50 gall Rheem tank to the tankless 5 gpm coil or an indirect tank in a series connection. Well will an outdoor Reset help in any way in this set up with or without a tank and is Taco/ Beckett or any other a good one . In fact what I am asking is which in your opinion the best ODR for this situation.

ODR

Dump the coil, add an Indirect and zone priorty. I use Taco so in your case add another zone for the indirect and use a  ZVC-404EXP Zone Control then add the Taco PC700 reset card that plugs into the zone control. It's a simple install for a simple system like yours. Use the energy you all ready have being produced and are paying for. Don't add more energy usage as you will be with the elec wtr htr.  Rule of thumb, for every 3 degrees I can run my system below 180 degrees I save 1 percent of fuel.

Have the same boiler

and added an indirect and outdoor reset to the system a few years ago ( abandoned the coil ) . We cut down fuel use 30% . Been at that figure for the 4 or 5 years since the switch .
