@rhysdavis6525منذ 2 سنواتThanks again Mike! Fantastic videos, I've learned so much from you, you're like my second teacher. God bless you and never stop, we'll always be here! 2

@thealexanders7828منذ 2 سنواتThis was a great video. I always wanted to know how these values were calculated. I knew of the heat load calc, but I never saw any HVAC consultant do one! Thanks for sharing! 1

@JohnBaker-vu2hbمنذ 2 سنواتI would like to see how you do a load calc for forced hot air and ac. 4

@bnice12منذ 2 سنواتEco Tec is fantastic, so user/installer friendly. I hope that a mag separator was installed though being as that it was a cast iron to stainless fire tube modcon. 1

@asalazar7696منذ 2 سنواتGreat video mike thanks , what if u install a combi boiler how much more Btus should u add ? 1

@modestohodesto7140منذ 2 سنواتGreat video M Pipes. Few questions if the original boiler is 130,000 btus why is make up air a concern with a boiler with half the btus? Also most id="hidden4" class="buttons"> if not all combi boilers have 2 btu ratings one for heat and one for domestic hot water. Lastly turn down ratio is only useful when an outdoor reset is installed. Keep up the great content. ....وسعت1

@jeremygrund8623منذ 2 سنواتMike, I’m happy to hear you talk about to Eco-Tec. I have installed 6 so far in the last 2 years. Really have come to love the unit. Piping is very accommodating. Love the manifold they provide. Wiring is also incredibly accommodating. I love that they provide SPACE for the wiring it gives you the ability to really be intentional about doing clean work. They also provide like Bosch a wall templet you can hang and prefab anything you like. One difference is they need to have a thermostatic mixing valve on the domestic hot water side. But man they are a great machine. ....وسعت2

@Tsikuraمنذ 2 سنواتI always wondered one thing with cast iron boilers and multiple zones. If that boiler is not a modulating unit and only the kitchen area calls for heat id="hidden8" class="buttons"> (30k btu), won't that cause cycling on the boiler? What is usually done to help the boiler work more effectively? ....وسعت1

@michaelsannuti270منذ 2 سنواتDo you do all these calculations as a part of a free estimate?

@
@desmo8755قبل 5 أشهرAppreciate your thoughtful approach, but it looks like the sizing is based on the available baseboard and radiant capacity, not heat loss of the house. id="hidden9" class="buttons"> What if that was sized wrong to begin with? I have found even 300 miles north of where you are here, in a nothing-special older house, 30 BTU per square foot is ample (70 degree delta). This client of yours has enough radiator for 45 BTU per square foot. And will need a larger boiler to service that, but isn’t the bigger concern that if there’s too much radiator area the return temps could be too low? ....وسعت
@
@mikegrabowski2052منذ 2 سنواتMike what is the going hourly pay rate in your area
@
@jasondelo4354منذ 2 سنواتSo would it be safe to say that it’s roughly 50 btu per square foot for new construction? Cause that’s what I get when I ask google. I’m doing a new construction in the north east.

@DCHVACمنذ 2 سنواتYou should do a video teaching us how to size for air conditioning.

@mikeray4002منذ 2 سنواتSeriously you need to add the Lefty Lucy righty tighty dinosaur logo somewhere on that shirt I'd buy one if it had it. LoL
@
@rustyshakleford5230منذ 2 سنواتI'm in Upstate New York and I would say probably 80% of the boilers I come across in houses more than 100 years old are oversized or grossly oversized. id="hidden11" class="buttons"> They sized the boilers back when insulation was a luxury and double windows were a massive luxury. One of the old guys told me that they used to size boilers just off the number of bedrooms. ....وسعت2
