| Sep 4, 2021 at 17:38 | comment | added | Alessio Sangalli | @ThreePhaseEel 5HP 60gal dual stage 170PSI compressor; the pool is 18x36, 3-1/2 to 8ft deep, I think 26kgal. The plan to heat it up is to install solar heat (not photovoltaic) panels first, and MAYBE in the future a heat pump, that has not been spec'd yet (hence the 100A panel at the pool) | |
| Sep 4, 2021 at 16:25 | comment | added | ThreePhaseEel | @AlessioSangalli -- oh, and how big is the pool planned to be? | |
| Sep 4, 2021 at 16:08 | comment | added | ThreePhaseEel | @AlessioSangalli -- how many HP is the air compressor? | |
| Sep 1, 2021 at 23:28 | comment | added | Alessio Sangalli | @FreeMan OK I applied for a permit to lay gas pipe to the garage. I did not cancel the electric tankless idea, but at least I should have an easy way to upgrade to gas later. | |
| Sep 1, 2021 at 4:13 | comment | added | Alessio Sangalli | @ThreePhaseEel I have three 20A, 120VAC circuits that each serve three "double" outlets. There is a circuit dedicated to the dishwasher and another dedicated to the garbage disposal. | |
| Sep 1, 2021 at 2:45 | comment | added | ThreePhaseEel | @AlessioSangalli -- last but not least, how many circuits serve the kitchen countertop receptacles in your existing house? | |
| Sep 1, 2021 at 2:20 | comment | added | Alessio Sangalli | @ThreePhaseEel oven = 9.2kW at 240VAC, range = 11.6kW at 240VAC | |
| Sep 1, 2021 at 2:07 | comment | added | ThreePhaseEel | @AlessioSangalli -- can you get us the kW ratings for the range and oven in the main house? | |
| Aug 31, 2021 at 14:59 | comment | added | Alessio Sangalli | @FreeMan well, it's not really about what my mind is set to, but what the permits say. It took me several months to get them and this is what it is for now. | |
| Aug 31, 2021 at 14:59 | comment | added | Alessio Sangalli | @ThreePhaseEel the pool pump is a variable speed "16A, 3HP" at max load The weldenrs, plasma cutter are all dependent on the settings as far as current, but they all call for 50A breakers. It's pretty unlikely I will use more than one at the time. The milling machine is only 3HP. If needed I could create an accurate table of the peak loads, what do you think? | |
| Aug 31, 2021 at 14:53 | comment | added | Alessio Sangalli | @ThreePhaseEel hey no, the house has electric (induction) range and electric (double) oven. Both have their own 50A breaker. | |
| Aug 31, 2021 at 12:13 | comment | added | FreeMan | I'll jump on the on-demand water heater bandwagon... Sure, your demand might be low at the BBQ, and even in the garage, but I'll bet that you're going to use it far more than you'd imagine, once you get used to having it there. Since you've got gas at the grill for cooking, why not use it for hot water? Don't know the piping in the garage, but the long-run says it'll be cheaper to bring gas there for your showers than electric will. Then again - it's your place and your mind seems to be made up... | |
| Aug 31, 2021 at 11:39 | comment | added | ThreePhaseEel | @AlessioSangalli -- I take it the main house has a gas range too? Also, can you provide us info about the current draw of the heavy tools in your garage, and the HP of the pool circulator pump please? | |

| Aug 31, 2021 at 3:07 | comment | added | Alessio Sangalli | @EdBeal, as English is not my Language, I sometimes write in a way that is too convoluted, I apologize for that, and let me clarify: the BBQ area will have two sinks, for convenience. The electric heater will provide warmer water useful to rinse down greasy hands. It's a (fancy?) BBQ area, nothing more. The garage will have a bathroom, I predict, to wash greasy hands from working and I also put in a shower for convenience. As you can see the usage will be light. In the house I have a 200k BTU/hr gas heater that I am very happy with. | |
| Aug 31, 2021 at 1:05 | comment | added | Ed Beal | Just chiming in as an electrician that would say think 3 times about on demand electric, they are fine for a small booster but you really want gas. on demand I have had gas on demand and loved it but after multiple west coast homes that even went back to tanked after upsizing services to be able to handle a large electric I would not go that direction, just consider blackouts, no joy for electric hot water , but if you have gas your generator can provide water even in the country, my big generator can’t push a large water heater if electric, think again and remember electric rates , going up! | |
| Aug 30, 2021 at 23:53 | comment | added | Alessio Sangalli | The new garage will be about 810sq ft with a 63sq ft bathroom. House is about 2800sq ft and I don't really have much going on there. Clothes dryer is gas, furnace and water heater gas too. No Air Conditoining. I am pretty sure I never use more than 50A for the house :) | |
| Aug 30, 2021 at 23:47 | comment | added | Alessio Sangalli | About water heater: I have a tankless gas heater installed in the house. I love it. However for the two sinks that I will install in the BBQ area, the usage pattern, installation location (directly under the sink) favor the tankless electric. With a 100A panel, there should be no problem. I will have gas for the grill/griddle/wok. I have worked on controllers for 500kW pumps, so a fully resistive 20kW load is not really that impressive... :) | |
| Aug 30, 2021 at 23:06 | comment | added | ThreePhaseEel | How many square feet is the garage going to be, and do you know the size of your existing house + its loads for that matter? | |

| Aug 30, 2021 at 22:34 | comment | added | manassehkatz-Moving 2 Codidact | Seriously consider traditional tank water heaters instead of tankless. The on-demand power for tankless is insane. If you had gas it might be a different story. But consider that the 18kW tankless heater is roughly equivalent to two car chargers! A typical 50 Gallon "regular" heater will have 2 x 4500 W or 2 x 5500 W elements only uses a 30 A 240 V circuit. Your 18kW tankless will need more than double that. | |
