I installed a Teledyne-Laars boiler on our home heating system about 10 years ago. It has been quite reliable but two years ago the external side of the tubes became covered in soot and could have been due to a poor flame. As a result the unit had to be opened up and cleaned. It has been working fine since though the flame is not the bunsen blue that it should be. I now keep a mirror positioned such that I can monitor the flame in the firebox. I have also installed a carbon monoxide detector to warn of gases that might not be getting up the stack. The bench test efficiency is claimed to be about 80%. With todays high cost of gas, I am considering installing electronic ingintion and stack damper to improve the efficiency which can be a lot lower due to the stand-by losses.
: Teledyne-Laars (Triangle) boilers are widely used in my area for heat or pool heating. They do not require more than normal attention. As they are small-tube copper boiler boilers in a cast-iron header, the flow of water through them should be established at all times and the speed of the water through them should not be excessive (to prevent wear).
