I currently have an oil fired boiler and a tankless heater that I want to upgrade. My house is 30 years old. My questions are:
1.) What brand for a boiler 2.) What brand for a Hot Water Tank? 3.) Direct or indirect for water heater? ( When calling for quotes to replace the system I have gotten two recommendations for the hot water tank, one says direct for efficency, the other states indirect because they are aluminum and will last a life time were the direct will be 5-7 years tops.
