I know I am an electrician asking a plumbing question... :confused: let the jokes fly... :p
But after doing several new homes in the Lehigh Valley area, I have noticed that anyone getting an oil fired hydronic heating system often gets a electric water heater and they are hooked together. My question is does this really save that much money in oil bills? If so, I think I understand the basic concepts involved with installation. Please feel free to correct me. However what is the best way of suppling the water heater (Ie: with a mixing valve, directly from the boiler, also should I install a return loop to the boiler with a ciculator pump.? )
Yes I am slightly confused.

SPARKY , IF YOUR USING THE BOILER TO HEAT THE DOMESTIC WATER,THE BOILER WILL RUN ALL YEAR .THIS WILL HAVE A HIGHER BILL.YOU ALSO WILL HAVE TO INSTALL A BFP ON THE AUTOFEED AND A TEMPERING VALVE /MIXINGVALVE TO TEMPER THE HOT WATER TO 125f. BY CODE. YOUR ELECTRIC WATER HEATER WILL HEAT THE WATER UP ANYWAY,YOU REALLY Don't NEED THE HELP FROM THE BOILER ,IF I READ YOU QUESTION RIGHT.BUT IF YOU HAVE A STORAGE TANK ,YES YOU WILL HAVE TO FEED THE TANK AND RETURN IT BACK AND YOU HAVE TO INSTALL A TEMPERING VALVE.ON THE AUQASTAT YOU WILL SET THE TWO LIMITS 20 deg apart .I see then date was a while ago .good luck .I would never recommend a oil fired and electric water heater, costly compared to gas , plus it it will be less maintanance ,way cheaper to ru . Plus the oil fired heater will tear up a liner compared to gas. Good luck.
