boiler

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...

I have a Burnham hydronics series 2 boiler and it’s only heating the finished basement zone and not the upstairs zone. It started by only heating the front rooms of the house upstairs and now it is heating none of them. The Taco zone box shows there’s a call for heat. And I hear the pipes...

Just bought a house with an older boiler. It's been working pretty well, but I need to replace a couple of zone valves. I am an electrician, and pretty handy with tools but I have no experience with boilers and don't really want to flood or blow up my new place. I can replace the valves, but I...

hi all, I’m trying to troubleshoot an issue with my boiler. If one person is in the shower at a normal hot temperature and another person runs the kitchen faucet at the hottest temperature then the shower will go cold. Any idea why? I have checked the temperature and pressure on my boiler and...

We have a hi-efficiency, natural gas hot water heating system. The maintenance man said that our circulator pump was undersized for the size of the boiler. He said this would shorten the life of the boiler/pump. We don't have a problem with getting enough heat in the house. The house is almost...

Hey guys, new to the forum here but seems like a great resource for this sort of stuff. I'm just finishing my first home build and have installed pex tubing throughout the house. It's approx 2600 sq Ft including the garage (which I also put tubing in and plan on heating). I am located in BC...
