The electric boiler is basically a beefy, in-line hot water heater which, being in a closed system, does not have as great of a temperature lift from source water to output as a DHW inline heater would.If gas is more affordable in your area, then rather than ripping out all the existing supply lines and trying to install ductwork for a furnace - which can become expensive quickly, particularly if multiple levels or stories are involved - you could simply replace the boiler with a high efficiency (95% AFUE) gas fired boiler.

That being the case, you need to become an expert on analizing the costs yourself.Here is what I would suggest: Spend many hours at Home Depot and/or Lowes to familiarize yourself with costs on typical rehab items such as flooring (carpet, tile, travertine, etc), toilets, bathroom vanities, sliding mirror doors, interior doors, baseboards, door casings, light fixtures (celing fans, etc) paint costs + paint supplies (tarps, brishes, rollers, etc), windows, sliding glass doors, kitchen cabinets and countertops, sod, trees, plants, bushes, ground cover, etc.

Holy smokes, I was born in Allentown.
