Hot water baseboard heating system gurgles a lot
Hi. We just moved into a house with a heating system that is oil-fired with hot water baseboards. The house was built around 1990 and these are 'modern' low profile baseboards, not tall vintage type with bleeder valves. Often, when the circulating pump starts up, the heating system does a lot of gurgling as the water moves through the baseboards. Am I right that this is happening because there is air in the system, and more water needs to be added? Am I also right that this WATTS valve right near the expansion tank is the answer? How do I use it properly? There is no pressure gauge on the system. https://preview.redd.it/rtcww89danqe1.jpg?width=3129&format=pjpg&auto=webp&s=b53d7c3fd054c7be6dfdc0ae0725fc1b12dd7fdd https://preview.redd.it/i050j58danqe1.jpg?width=3024&format=pjpg&auto=webp&s=eb6276d10b61d57e89e44254b613847b85dd76ed submitted by /u/MacProCT [link] [comments]
