Hi Terry,
I bought a house last year with an hydronic system (I've never owned one before so this is a learning curve although I am fairly handy until things get too complicated) consisting of a Dettson boiler with 3 zones. The house is a bungalow with the basement as one zone and the upstairs zones 2 (all the bedrooms) & zone 3 (livingroom, dining room and kitchen). Zones 1 & 2 work fine. Zone 3 has 5 baseboard rads (they look like electric baseboards but have the copper pipe runnning through) and is the farthest from the boiler. The first rad in this zone (from the boiler) gets almost hot (extemely warm?) and then the other 4 get progressively cooler even when we set the thrmostat to 25 or 30 C. My boiler is running around 15 psi when heating. I thought it might be air, so I put a self piercing saddle valve in the 4th rad (2 rads away from the return) and bled the line but it didn't really need to be bled. I was going to try and flush the zone but didn't know how. The only valve I could see is a bell shaped fitting in the water entry pipe. Any suggestions?
cheers,
Kim
