If the primary goal is the prevention of boiler scale and related heat transfer efficiency, magnetic scale reduction might provide positive results. However, when the treated water is exposed to the atmosphere, the benefits and performance degrade quickly and substantially. None of the...

I believe the CG5 is an atmospheric cast iron boiler. Not my favorite for floor heating. A properly installed firetube ModCon can achieve 90+ efficiency, with primary/secondary plumbing, a system pump, PVC air/venting, outdoor reset, and condensate neutralizer. Lots of material and labor for...

What happened to the boiler? Cracked? Hole in the section(s)?

A recent price change for one of my clients...40 seconds per dollar. Anticipating similar pricing at other client locations soon.

Fred is correct…no need to be alarmed, yet. TDS above 50PPM will start to show spots so you’ve still got life in those membranes. Low energy membranes (cold water) are a good solution for increased production. Short cycling of the RO system…it’s always best to have extended run times for the...

I still believe you have a leaking check valve. There are 2 CVs under each of the pumps. The lower CVs are plumbed with poly tubing from the weep solenoid. If one or more of the lower CVs are leaking, that high-pressure leak pushes water back through the weep system water supply and into the...

“more so since it got colder out.” A leaking weep system check valve might be the cause. Consider this possibility: High pressure soap past the leaking check valve sends soapy water into the weep system supply plumbing…through the open weep solenoid…into the water supply. If that’s the case...

Since we deal with freezing conditions every year, our systems are automatic. We fancy. :LOL:

mjwalsh, By-pass valve is for boiler protection. Without the by-pass, cold return temps result in excessive condensation. Providing 130°+ return temps via the by-pass heats the tube bundle and flue faster, reducing the condensation cycle. 1/2" bypass valve & piping might be fully open. Larger...

I am not aware of wifi capability for Nayax. It's either their standard cellular or your LAN. LAN requires CAT5 to each meter box.

Nayax offers THIS ADAPTER for hardwired installations. It plugs into the back of the reader and provides an RJ-45 female socket for the Cat5e/Cat6 network cable. Install a network cable from each meter box to an equipment room network switch. The network switch then connects to your DSL/cable modem.

Eric, My library of Raypak manuals has long been discarded. However, here's a copy of a DHW boiler manual from Huron Valley Sales' website. Page 12 outlines the make-up air specifications for similar hydronic boilers. RayPak Manual No by-pass valve? If so, the boiler is "seeing" cold glycol at...

The "root cause" is closed combustion air vents in the equipment room. Or, improper or closed boiler by-pass valve. Or, both! Operators who block the equipment room vents save on heating expenses and eventually pay for it with heavily sooted atmospheric boilers. Closed or Improper by-pass...

You can simplify the system by eliminating the foam generators and metering valves and improve product delivery with a few changes… 1. Air pressure regulators with gauges feed the FloJet and the air-assist solenoids 2. Run 1/4" poly tubing from each pair of solenoids 3. Connect the 2...

Weepmizer is commonly used in cold weather locations. It will save significant water and keeps folks from using the "free water". Leave the default settings alone...it works just fine. With the default 1 minute cycles: AT 34° water will flow for 6 seconds BY 25° water will flow for 30 seconds...

^ This Citing significant increases in expenses for energy, chemicals, parts...Several of my customers have gone to $5 to Start - $1/minute. IMHO...$2.00/3 minutes (22.5₵/min) will allow you to go broker faster. You're not going into the Car Wash business for the fellowship.

Pulse 1 wire must be connected to Dixmor LED6 Pin 8 (White/Black wire) You're welcome (in advance).
