once everything is up to temp its about twice the cycles as the old boiler did but the boiler had 500 lbs of iron to mitigate that. But its 95% efficient and the old beast was probably 50%? You could burn your self on the flue pipe.
When things are cold or when running the turbonics mvb fan coil it will suck the heat right out of the ex-changers cycling the unit more often. The reason for turbonics mvb fan coil was because in floor heat is not instant... and when the wife is cold... well you get the point, happy wife = happy life :thumbsup:
for adjusting the temp of the first floor loops, I just did what tekmar does, added another pump that kicks on and off feeding the manifold loop with hot water until it reaches desired temp. At first i didn't do this and the bedroom temps would over shoot its desired temps by 10 degrees during warmer days. Oh, i also put a temp sensor outside and pull the current temperatures from wunderground API.
the old boiler had a tekmar mixing controller which does exactly the same thing for the basement in slab zone @ 100f and cost $500.... raspberry pi does it for $35 :shocked: and I can pick what ever temps I want!
Hydronic systems have many loops and many pumps :laughing:
