I am considering converting from an oil boiler to a hi-efficiency gas boiler that can be side vented. Are these boilers reliable in the long run? Since I have an old 1800 sq. ft. centre-town house in the Ottawa area (Ontario) that uses cast iron radiator system (130 °F), my second question is how common is the Trinity boiler in older cast-iron heated homes. Is there an alternative that I should also consider?
thanks in advance,
