During the winter I had concerns about my heater not being able to hold temp or rise while on constantly for 40-60 min. I verified that the temp on the control panel was an accurate reading with both a digital and mercury thermometer. 97 – 102 were all accurate readings. When it was 60 F outside it took up to 25 min to raise 1 degree with top half open. During first winter I had no issues with heat.
Also I have been periodically having one speed pump # 2 shut off anywhere between 10 sec and about 10 minutes after turning on. I clean my filter every week and am not sure why this would happen.
