I have a Woodmaster 4400 and i have noticed that its preformance is dropping. The boiler could keep up with heating the house no problem to about -10 degrees then it would have a hard time recovering when the thermostat is turned up. This has been the case for the last 4 years. This year it does not seem to be able to bring the house up to temp when it is in the low teens outside. Nothing has changed this year compared to previous years other than our house he been more and more insulated. I am suspecting that the w to w plate heat exchange is plugging up. I use well water for fill ups and treat with woodmaster treatment each spring. The owb is holding temperature no problem. I would like to clean the plate exchanger but have to cut it out as there is no tee on the pex lines. I may cut the pex and put in tees with a valves so i can easily clean the exchanger in the future. Do i need to clean the oil burner side of the exchanger? I have done nothing with the water on that side ever. Could it be another problem? I believe the circ pump is about 10 years old. Its a taco 011. Could that be getting tired and slowing the amount of hot water to the oil boiler?
