the house I bought has a steam boiler from 1984, and its super rusted on the bottom, I think its time to replace it.

thanks, for the informantion

Lol, reducing temp is not equal to increase in efficiency

It is too often heard that “your boiler size is too big, “ this should be told to the plumbers, not the house owners. The plumbers want to make money so, they always install over capacity of boiler to their customers. The plumber treat the homeowner as an idiot

Love your Vid! Thanks! im also doing SHW! at Guilt Free Hot Water,,nothing to sell but i use a small 20 volt 25 watt DC Pump to cerculate

How can we do a beat loss test if the boiler is broken? I just bought a home, boiler was working and the next day after closing the boiler is dead... it was a 175k BTU and I got an estimate from a plumber about fixing it. He recommended a new 200k BTU.

i understood completly everyrhing

Is oil boiler or gas boiler better ???

How does a consumer find out the minimum firing rate, it does not seem to be a specification that the manufacturer publishes in their literature or owners manual?

Very informative vid, thanks for posting it. Contractors seem to just want to replace your unit with what you had. I have a 35 year old unit, the house since has had energy efficient windows, siding installed. The boiler is also in a heated space in a lower level closet (high ranch). The old boiler seemed too much for the size of the house and based on fin tube feet in the house it is. Would love to do the heat gain loss calculation but seems difficult.

This is for space heating a home. I'd like to see a video on how to reduce the cost of owning a hot water circulator ruclips.net/video/9q5V8k2R7wc/видео.html

Modern boilers don't boil water. Only steam boilers do that. Modern boilers are high tech water heaters.

...lol...''even when your pumps at its smallest state''...poor use of 'words'..lmao

Don't purchase a Crown Boiler, from a Company Called surplus city liquidators, very dishonest, Be careful they , Advertise on AMAZON, BUYER BEWARE

Nothing has changed in 120 years, all the new crap has High ROI and low life span - Keep an eye out for the New H N-P I Electric Water Heater - Cheap 75% saving of power, - Lower cost to buy, 1/2 the weight, 100 year lifespan - No explosion hazard

I am sure you can still buy handbook with all info you need on INPLIX. Just google it.

How do you work this when your using a primary/secondary pipe scheme? They always have a primary pump and either a pump for each zone or z valves and a single secondary pump.

so how do you calculate correct size? if its 4 btu per square foot, theres no difference going to each room, and multiplying 4 by x amount of sq in each room. you still end up with same amount of square feet in the house.

My boiler takes 45mins to heat up room by 2 degrees on cadithrial ceiling.

Nice, good information and explanation, Rinnai in US is offering the single three speed circulator with multiple zoned valves, way to go I guess until and unless any one knows a better brand in US. My only concern is the Rennai E110C may not be sufficient for a house between 2000 to 3000 sqft during extreme cold days of below 20 F weather

Hi, I like this presentation. Very informative. What is meant by "the boiler very quickly reaches temperature" around 1 minute and 20 seconds? Are you talking about the boiler very quickly producing the heat required for the applicable zone to reach its desired temperature? Thank you!

That Looks like a SuperStor Indirect Stainless Steel water heater (lifetime warranty) featured in this movie

Great summary, thanks!

The USA is way behind the UK and other parts of europe with this type of system , in the UK we have been using a single pump multi zoned system for the last 30 years +

Hmm ...published on Jun of 2012 but zero comments? What gives?

Excellent presentation. Thanks.

Excellent ! Clear ,simple and factual . Thank you,keep up the good work.
