Ditto above about great place [emoji106]- I also use Pex Universe Supply, they have better pricing in some items and great for plumbing fittings etc. Sent from my iPhone using Tapatalk

You’ll have to decide as to what cost factors are key for you. First cost versus operating cost. Agree that Radiant be real nice, but realize it’s not a option for quickly warming up working area. Id consider it for keeping shop warm full time at whatever temp you desire. Then for the...

Tall yellow in one area could be caused by deterioration around the gas orifice or air shutter. Too much air flowing in that area. Your cleaning process will expose it if so - good luck. Cool old heater [emoji106] Sent from my iPhone using Tapatalk

Not at all an issue. It would be a Closed loop hydronic loop, They s/b filled/pressurized to have ~5 psi minimum at high point and systems get purged of air on fill set up. Then have an air separator/removal device in line after heat source at pump suction. Sent from my iPhone...

If cost is the main driver, consider radiant or a fan coil unit maybe. Sent from my iPhone using Tapatalk

LAARS mascot nice choice, they have very good install manuals that will help you with piping needs and venting etc. follow the manual for best results! I don’t think you can find a boiler with low enough firing mode for small heat lo adds like you’ll have. All you can do is make sure...

Pump sizing is easy, once boiler decision is made. Then need to know how the Pex is laid out. And distances and piping layout. Sketch that our and could assist you as needed in pump sizing. Keep the loops close to same lengths to avoid requiring balancing, and keep lengths at 200 ft...

As far as the non ox barrier - be sure that you use only non ferrous piping and components. No steel only copper, brass, bronze, stainless steel. Basically treat the system as if it was a potable water plumbing system. This will prevent oxygen entrained water from corroding the piping...

I saw the $100, so if it was $ 60 with gas, and say 5 months heating season that is $ $ 200 year savings ..... do the math on paypack period when you factor in the true total install costs + maintenance on hieff condensing gas heater to determine true “savings” . Some folks don’t calculate...

Curious as it varies depending on where you are, utility company. have you calculated the BTUH costs if electric versus gas already? Sent from my iPhone using Tapatalk

Your idea sounds good to me, I’ve been involved in hydronics industry many years by the way. And radiant heated a couple if my personal homes and garages in past. A major issue is to have proper design to minimize heat costs and install issues. First and foremost is perimeter and slab...

I’ve used “320 adhesive” - it seems very similar to contact cement. Sent from my iPhone using Tapatalk

Oh and if you are new to pipe insulation- try using mitre box and hack saw blade to mitre cut the 90 elbows from the 6’ tubes. Then glue. Ends up looking cleaner and seals better. Sent from my iPhone using Tapatalk

Yes on insulation on all piping you can. Your goal should be keep the heat in the fluid to get it to floor. If you need good source check out Express Insulation on web. They even have sheets if you find it necessary to enclose sections that are piped to tight to use pipe tube type. And...

Look at “Retroplate system” website. Many variations on final look, that or similar is used at Depot type stores. If you have any experienced installers near you I’d suggest look at their work. I was sold on it when I saw it on my contractors warehouse floor. I’ve got my 2000 sq...
