I have a weil mclain boiler that was installed in 2004. It's

Hi, I have a weil mclain boiler that was installed in 2004. It's a LP version and I have two problems: 1) when I take a shower the boiler comes on, runs its cycle and when it hits 4186 the power to it goes off. The screen is dark, the boiler is completely shut down. I have had plumbers and electricians out here, no one knows what is causing this and it will mean I won't have heat or hot water for the winter. 2) there is a leak somewhere in the system, I lose 2-4# ***** a day. I think we'll be able to put a valve on that to refill as necessary. The boiler itself had a maintenance kit put on it last October so it has been maintained. I really need help as I'm out of options for local service people.

Whats involved in changing it.I would like to install 2x2 tile duct vents. Whats involved in the installation? Which make / model would you recommend?I would like to split the duct work going into one room to another room which has no duct work.

I am looking at a commercial space that is about 6000 sq/ft

My name is ***** ***** I am looking at a commercial space that is about 6000 sq/ft with 20 ft ceilings. The space has no HVAC to speak of other than an undersized radiant heat unit suspended from the ceiling. My question is: for a room of that size, with no existing ductwork, how large of a unit(s) would be necessary to heat/cool the space? How much would such a unit cost?I am in Minneapolis, MN. Thank you!
