It doesn't matter if it has a reservoir and it doesn't matter how big the reservoir is, it will always be empty.

haha!! Holy shit that sucks.

So... I'd have to adjust my estimate up a bit...

According to Chatgpt...
what size boiler for in floor heat in a 1800 sq ft single story residential dwelling?
ChatGPT said:
The size of the boiler needed for in-floor radiant heating in an 1,800 sq. ft. single-story home depends on several factors, including insulation, climate zone, and heat loss calculations. However, a general estimate can be made using the following steps:
1. Heat Load Calculation
A rough estimate of heat loss is 25-50 BTU per square foot, depending on insulation and climate: Well-insulated home (moderate climate): 25-30 BTU/sq. ft.Average insulation: 35-40 BTU/sq. ft.Poorly insulated (cold climate): 45-50 BTU/sq. ft.
For an average home in a moderate climate:
1,800×35 BTU/sq. ft.=63,000 BTU/hr1,800 \times 35 \text{ BTU/sq. ft.} = 63,000 \text{ BTU/hr}1,800×35 BTU/sq. ft.=63,000 BTU/hr
2. Boiler Size Selection
Standard sizing rule: Choose a boiler with at least the calculated BTU/hr.Condensing boilers: These are more efficient and can modulate their output, allowing for better efficiency if slightly oversized.Non-condensing boilers: Should be sized as close to demand as possible to avoid inefficiency.
3. Common Boiler Size Recommendations
Mild to moderate climates: 50,000 – 70,000 BTUColder climates or poorly insulated homes: 80,000 – 90,000 BTU
4. Additional Considerations
Water heater combination: If using a combi boiler for both space heating and domestic hot water, size up slightly.Zoning: Multiple zones may impact size selection slightly, but not significantly.Professional Calculation: A Manual J heat loss calculation by an HVAC professional is the most accurate way to size the boiler.

how much tubing is required to plumb 1800 sq ft for radient in floor heating?
ChatGPT said:
The amount of PEX tubing required for radiant in-floor heating in an 1,800 sq. ft. home depends on several factors, including loop spacing and layout. Here’s a general guide:
1. Standard Loop Spacing
PEX tubing is typically installed at one of the following spacings: 6-inch spacing (higher heat output, ideal for colder climates)9-inch spacing (moderate heat output)12-inch spacing (lower heat output, well-insulated homes)
2. General Tubing Estimates
SpacingEstimated PEX Required6 inches~3.0 ft. per sq. ft. → 5,400 ft.9 inches~2.0 ft. per sq. ft. → 3,600 ft.12 inches~1.5 ft. per sq. ft. → 2,700 ft.
3. Loop Length Considerations
A single loop of 1/2" PEX should not exceed 300 ft. to maintain proper water flow.A 1,800 sq. ft. home will need 9-18 loops depending on spacing.Typically, 1/2" PEX is used, but 3/8" or 5/8" PEX can also be used in some cases.
4. Additional Factors
Manifold Location: Placement can affect tubing runs.Room Layout: Complex layouts may require extra tubing.Extra for Waste & Turns: Add 5-10% extra for waste and connections.
Final Recommendation
For an average 1,800 sq. ft. home with 9-inch spacing, you’ll need about 3,600 feet of PEX.
For 6-inch spacing, plan for 5,400 feet.

1/2" looks to be about fifty cents a foot. Nice.

Radiant heats surfaces, rather than the air like forced air does, which ultimately heats the surfaces too... If I were going to do this (and I may) I'd def go with pex. I've got a single story ranch with a full access 4 block crawl...

I could probably do the whole thing in two weekends for around $6k

I know. Don't you read good?

I don't think you'll even need a contractor to design it, it's pretty simple. Figure out how many zones you want, build a manifold. I bet you will find all the info you need on youboob.
Retrofitting radiant heat can be tricky routing the supply and return lines. In-floor would be the way I would go, but that might be a no-go in a retrofit scenario...

Order a nice one from Amazon. In the meantime, get that percolator out of the cupboard and make some real coffee.

Sitting here watching old SNLs on this TBD channel... Not sure which season... Clinton was getting impeached Vince Vaughn is host. Every fucking commercial is geezer drugs and health insurance. Gee look... I'm old.
Anyways...

A friend of my dad's had a brother who was a lawyer. He served in Korea as a grunt then came home, moved back in with his parents and used his GI Bill money to go to lawyerin' school. He was five years with no taxable income so he didn't file. Thirty years later the IRS came knocking, having noticed a gap in his filing. They didn't believe his story that he was living at home going to school and had no income. They averaged his income over his taxpaying life and adding interest and penalties, handed him the bill for his fare share.
