6 QuestionsQ: what size gpm circulating pump is required for approximately 125,000 BTU input, 3 zone, hot water furnace
Asked by Gene 14 years ago

Verified Reply- PexSupply StaffThis depends on the flow rate and head pressure in the distribution lines. Taco has a good instructions for circulator sizing at the link below. http://s3.pexsupply.com/manuals/1289252668477/41390_PROD_FILE.pdf
Q: my home is broken in to 3 zones, one that's 1238sf, another that's 432sf and the 3rd that's 400sf (total of 2070sf). will this boiler be appropriate for my heating needs?

Verified Reply- PexSupply StaffThis unit would provide about 49 BTUs per square foot, which is a safe figure for a house with standard insulation in most parts of the United States. To find out a your home's exact BTU requirement, you would need to perform a heat loss calculation.
It depends on many factors such as what zone of the country you are located, how well the house is insulated, how many windows and doors or other openings you have, how many feet of baseboard, etc. For the most part, this should be sufficient to heat a little over 2000 sq ft. You not only don't want to undersize your unit but also you don't want to oversize it too greatly as the excessive cycling of it will cut into it's efficiency. Good luck!
Hello, there a many factors to consider including insulation, direction windows face, desired temperature rise, etc. Here is a quick guide: http://www.ehow.com/how_7316740_calculate-btus-needed-home-heating.html I am not sure if this only applies to a forced air unit or boiler as well. However, the temperature rise would be the same for both.
It would take more BTU's than 102,000.
You will need about 115000 Btu's and it also depends on how old your house is and the region where u live. Ahan Nelson
Q: I am replacing a old oil burner. I am interested in using this boiler (cga-5) for my 2000sq home. My question can I set this up for two small zones in my basement and one zone for about 1000sq. ft. for a total of 3 zones?

Verified Reply- PexSupply StaffYou can. The boiler will work with as many zones as you want it to, provided that it is capable of supplying sufficient BTUs. Creating zones will require extra thermostats, controls, and either zone valves or circulators.
Q: i have oil boiler now with 2 zones would this be compatible conversion
Asked by dan 14 years ago

Verified Reply- PexSupply StaffYou can use this boiler for two zones with proper piping and zoning equipment. You should also confirm that it can handle the heating load for the building. Keep in mind that this is a propane boiler, not an oil boiler.
This is a propane fired boiler and will obviously not directly replace your oil fired boiler. As to the output capacity, you will have to compare it with what you currently have for the correct sizing. Multiple zones can be accommodated as long as you do not exceed the rated output for the total of all zones.Hope this helps!
i also switched from oil to propane and have two zone system but only have one zone working at this time because of remodeling. this unit is a great choice, was an easy install and have had no problems with over the past two winters.
Q: My current propane boiler provides hot water as well as heat to my residence. Is the weil mclain cga-5 a suitable replacement?

Verified Reply- PexSupply StaffIf you were to purchase this boiler, you will also need an indirect water heater for the domestic hot water.
Q: Where can I see a chart of a water piping in and out of the boiler? Especially, isolation valves?
