boiler

My Navien was installed 1.5 years ago and from the start, it had an issue with low-pressure water in the winter. The installer came to fix and it worked fine in the summer, however, in the winter boiler start showing error code E302 two or three times a week. My boiler provides heat to TWO...

Hey all: Several years ago when I had never used Hot Water Heating systems, I asked whether it would be a good move to replace it with Forced Air in our northern Michigan cottage. I am so glad that this forum told me I’d be nuts to do that. We’ve really liked the GWA-105N-I natural gas fired...

I have a Weil-McLain oil boiler, hot water baseboard, and the supply line froze (outside tank, overhead line). This happened last year too, so I had added heating oil additive to this year's tank, wrapped the pipe in heating wire and wrapped that in insulating tape. It still froze this year...

Hi, I'm here as a new forum user and could really use some advice. I have a 12-year-old timber-framed home that is covered with SIPs and has an ICF basement. Very well insulated. Live in southwestern VT about 40 miles northwest of Albany, NY. I have in-floor radiant heat in my basement...

Hi I recently installed a Biasi propane fired conventional boiler. It only has a capacity of 4.5 gallons of water, a far cry from what I was used to with my ancient oil boiler that had a high capacity. How it works is, home thermostat calls for heat and fires the burner, when aquastat reaches a...

I currently have a Grundfos UP15-42F recirculating pump on my boiler. There are 3 branches (all on the same zone) throughout the house. The branch with longest run and the most radiators does not get near as warm as the other 2 branches when the heat is not on for very long (> 60 min as when...

Hi All, I am about to start renovating a 280 sq meter listed farmhouse. Walls are solid, single glazing but underfloor heating fitted downstairs and roof insulated to latest regs. Initially, I was keen on a heat pump - but it now seems that these won't be suitable and will be hugely expensive...

Hello All, Im a newcomer here and a new home owner I have just completed a complete new full bathroom install in a single level ranch home from bare concrete in a basement (pic attached)and I am looking to convert some of the remaining space in the basement space to a media/family room. the...

Hi I recently had an L6006C aquastat installed to control the circulation pump for my Biasi cast iron conventional boiler (propane). What would be the best setting for the circ pump to come on and the correct differential? Want boiler protection to prevent condensate but don't want to waste...

Thanks in advance for any help. I recently had a propane boiler installed. Just trying to figure everything out and get the right settings. A little background. The circulation pump is controlled by the house thermostat and the boiler is controlled by a low limit aquastat. What temperature...

My neighbor just went from an old oil fueled boiler to a new gas boiler. The old boiler exhaust went out through the chimney. The new exhaust PVC opens out 5’9” from my garage. (These are old homes built in the 1920s before setbacks from the property line were implemented.) Does this exhaust...

Hi All, I've got a leaking circulator pump on my boiler. It appears that the gasket has failed and the exposure has done some damage to the flange and possibly the pump housing as well. I'm certainly no plumber but I'm pretty handy, so I'm going to try and replace this myself. Here is a link...

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...

Hi, I would appreciate any help on this. I have a 130 yr old house with a 5 yr old Buderus boiler running 3 zones. Two of the zones are fine and working on basic stats. The 3rd zone (upper floor) had a new wire run during recent renovation (by me) and I have since discovered that the wire is...

Hi It's been ten years since I had my Valiant combi boiler looked at, it had been working perfectly fine, but I thought now is the time to get it serviced... big mistake.... A young gentleman came around to look at it. The first thing he did was remove the vertical pipe cover, and bashed one...

I am compiling a list of designers/installers for a new Boiler/Hot Water Heater on the Saint Paul side of MSP. Need to select someone to design a system to replace my 32 year old Weil McLain VHE Series 4 (80 BTUh) with a Triangle Tube 45 Ga indirect tank. Downloaded my energy bill which has...

if anyone could give some ideas that would be great. I have a hot water boiler system that sometimes does not kick on when thermostat calls for heat. It is a 2 zone boiler system with two thermostats. The damper is in the always open position. When not running the water pressure is between...

Hi, I have an NTI T200 combi boiler/tankless DHW - installed in 2003. This for a 2 adult household. Loads are basement underfloor (approx 500 sq ft), one small radiator/towel rack, and a 120,000 BTU air handler (vents in all parts of the house - total 2000 sq ft). The house is older, but...

Hi, I have a NTI Trinity T200 Combi boiler installed 2003 and maintained consistently since then. I've been happy with its performance and economy, although I have also had a fair number of (relatively minor) issues with it - but I'm told these are "normal" (pump failure, igniters failing...

Hi guys, I have an existing 16-zone heating system using 3 Taco SR506-EXP switching relays wired in master/slave configuration. One of the relays failed out, so I went and got a new one, an SR506-EXP-4. Problem is, the old ones communicate with one another via 4 wires, labeled 1, 2, 3, and 4...
