I am replacing my oil boiler with an electric one as backup . My wood boiler is hooked up in parallel I think it is called . It has its own circulator and pumps the water through the oil boiler and back to the wood when the temperature reaches 190 degrees . I would like to hook the electric boiler up in the same way but the electric has 1 inch piping where as the wood boiler has 1 and 1/4 inch . My question is would reducing the water flow through the electric boiler by that amount be ok ? My current setup is simple wood/oil . I don't have any type of storage . Furnace room is too small for it anyway . Thanks
