I'm a new guy here, and hoping to maybe get a question or two answered. I installed a new CB 5036 about five weeks ago. Heating 1700 sq ft home, not the greatest windows, but insulated good.
The boiler is only hooked up to a 18 x 20 HX in the plenum and the plenum is 18 x 26. I plan on installing the exchanger for domestic hot water and other kick space heaters next summer/fall.
I have the Taco 009 mounted outside on the boiler connected to 1" pex about a 65 foot run from boiler to hx. I have a temperature gauge on supply and return line in the basement. I don't seem to be loosing any heat coming to the house, or very very little. But here is my question.
Lets say the boiler is up to temp (180*), the supply line is at 180* and when the furnace kicks on there is a temp. drop of about 22*. (Return line is at 158*). Is this a normal drop?
Another question is I have a digital thermostat hooked into the furnace. And I can set the span of when the furnace kicks on and off around a certain temp. I have it set to where it kicks on when its almost 2* below the set temperature of lets say (72*).
My furnace would be on I believe about 40 minutes to get the house back to 72*, and then be off for an hour or so. My boiler water temperature has now dropped to about 166*, and doing a burn to get it back to 180* takes about 25 min. Does this temperature drop calculate to about 24000 btu of water heat was used since the boiler holds about 200 gallons? And does my HX that is rated at 120,000 btu, actually would transfer 120,000 btu of heat in an hour if I were able to supply 180* thru it for the hole hour?
Any answers or comments would be great thanks.
