hydronic heating

Working on a commercial lobby with curtain wall areas 18ft high. I wanted to use recessed forced flow floor heaters and radiant ceiling panels to combat the load (0.5MBH/ft / 0.48kW/m). Thoughts on this? I've read the trench heaters accumulate debris, the Arch wants something that is recessed as...

Hi there, I am looking for some second opinion from the wonderful community here. Previously I was using an oil based boiler and recently converted to a Naiven combi boiler NCB240-130H with a 3 zone smart thermostat and aluminum fin baseboard. While looking at the primary loop of the pipe...

I'm looking to replace my Rinnai tankless water heater that is used for hydronic heating (w/ wall-mount convectors) and domestic hot water. The system is open-loop so I want to use this opportunity to make it close-loop as well. Most of the contractors that came to estimate propose Navien combi...

So i'm about to disconnect my old Weil-McLain boiler and hook up a new Navien NCB 240 combo boiler which we've been using for DHW since January. I know, I've already been told elsewhere on here that the NCB 240 is overkill for the size of the house and may likely not work efficiently because...

My brain teaser is this: a 60 year old boiler heats 4 one-bedroom apartments and does a fine if inefficient job. However one bathroom has always been cold, so I added two 1/2 inch copper lines, supply line is about 15', to feed a new hydronic kickspace heater. All existing lines from manifolds...
