Triangle Tube Prestige heat exchanger cleaning
To contractors that have TT prestige boilers installed on natural gas how often are you inspecting and cleaning out the heat exchanger? I know it should be serviced and cleaned every year but are home owners really getting it serviced and cleaned every year? If you are cleaning it every two to three years what does the heat exchanger look like? any photos of the heat exchanger before you cleaned it? Are there any other problems with this boiler that you have experienced after they are in for a few years? The jobs where you switched your customer from oil over to nat gas with the TT Prestige series boilers how much have they lowered their heating bills using nat gas condensing vs old oil boiler?
