Cast iron gas boiler versus high efficiency gas boiler for heat

[Mark Berge]

I am getting estimates on replacing a old oil boiler with a new gas boiler to heat the rental house. House is 1000 square feet with baseboards. Have gotten estimates $11,000 to replace with a gas high efficiency boiler. I'm thinking maybe cast iron boiler would be less expensive and simpler to maintain? Any feedback. The house was built in 1964 and has 3 br, 2 bath sfam det in north jersey.

Another way?

Know gas is big on the East coast.  You might take a look at using a electrical "Split" system since the house is only 1,000 square feet.  Especially if just one level.  Check in your climate first though, with an HVAC person.

Compare your operating costs.  Gas versus electric; system to system.
