It is a two zone system. One side of the home is on one zone and the other side is on the other. Here is my problem.

It is heating well and water is coming out of all radiators downstairs and main level. Barely any heat is coming from the upstairs radiators and no water is coming out when I bleed. There is air that comes out but then nothing comes out after awhile.

I believe there is a lack of water in the system. I have traced the water intake from the boiler and there is a pipe going to the hot water tank. I ensured both valves were open on the line but nothing.

The pressure gauge is at zero when it should be between 35 and 40. Which I believe is from the lack of water in the system.

If this is indeed a water shortage problem how can I add water to the system?

I can provide more info if required and pictures. I would really like to get this one fixed asap.

Thanks for any help, well appreciated. ]]> HVAC TremblayElec http://www.contractortalk.com/f6/three-level-house-boiler-system-68439/ http://www.contractortalk.com/f6/friedrich-2-ton-heat-pump-fan-speed-68361/ Thu, 19 Nov 2009 02:38:19 GMT We just installed this unit - MY24CF mini split and the only issue is on heat mode it plain out ignores the setting on Fan speed. Has it's own mind. Getting cool up here, but we could run the a/c cycle and worked fine on whatever the selected speed was.
We have a 3 ton unit with 4 room units feeding off it and they respond on heat mode to the different fan settings.
With the 2 ton unit it might blow fairly hard one time then next time you check it is barely moving. It does blow quite hot air.
Outside temp has been mid 50's

Since the boiler has to run to keep hot water for daily use, even when home heating is not required, I have been investigating having a propane-fired Rinnai tankless system installed. I could shut down the boiler during the months when no home heat is needed (probably 8 months out of a year) and just use the Rinnai for daily hot water needs. I was ready to give the go-ahead for this installation until the guy who did the service/maintenance on the boiler came the other day.
He mentioned something I have never heard of...a "Triangle Tube Indirect Fired Water Heater" http://www.triangletube.com/Triangle...?CatID=6&PID=2
He said he uses one with his oil furnace and has seen a 25% reduction in oil use.
What to do? Anyone familiar with these Indirect Fired Water Heaters?
Just looking to save some money in the years ahead and would appreciate any feedback. ]]> HVAC Robie http://www.contractortalk.com/f6/trying-cut-energy-costs-dilema-68350/
