NG Combi Boiler versus indirect tank and boiler setup
A combi boiler seems like a no brainer from the specs and what folks are telling me.
Right now we have an oil cast iron boiler that is 150kBTU. It has the domestic hot water and house baseboard heat feeding a 3350 sq foot house. The unit often short cycles and seems a bit oversized. A heat loss analysis is currently underway the right way to help determine actual needs.
Making the assumption that the ultimate choice of a unit is sized correctly for the house, people are telling us the unit will work perfectly for our needs. Our overall requirement is to run two showers and heat the house. If that means buy a bigger unit, no problem here. Naiven has some bigger units in our budget with 7.6 GPH, else Bosch or Triangle Tube 96kBTU Output at the smaller end. I am just the average homeowner trying to understand real-life experience from people that know more than me.
Has anyone installed a combi boiler in a regular suburban home with 4 bedrooms and 2.5 baths in New Jersey area like climate? If so, how do you like your unit or how did it work out?
Looking for real-world experience on this one. The job is half the price going this route.
