New to the site and have a quick question: Gas boiler in house for heat and domestic hot water. Have four thermostats in the house - simple Honeywell dials - but don't see any zone valves on the boiler. Is this a 4 zone heating system?
Also - water heater is (blue) Amtrol 41 gal 115V. Is this just a holding tank for water that is heated by the main boiler?
Boiler is a Weil Mclain Gold GV-4 (series 2, I think) Serial number indicates a mfr date of 1994.
Lastly, is this considered a combination boiler?
Thanks for your help. Not real familiar with boilers.
