If you want same old-same old, then we got that in the US.
If you want innovation in hydronics...look to the Europeans...

That's interesting, Larry. I assume that tank is insulated? Or, is it giving up it's heat into the house?

Bill, Most if not all, hydronics tanks with coils in them would be as you assumed, with lots and lots insulation covering them, :)

What is wrong with the US method of just treating the hot water as another zone with circulator to a tank with coil? Seems simpler and better to me.

The key is to transfer the heat left in the boiler into the domestic hot water tank, after the boiler has shutdown. Energy Kinetics figured this out nearly 40 years ago, and still makes their boilers in NJ. If I ever buy another oil boiler for my house, it will probably be from them.

You can't transfer the heat out of a boiler that has satisfied a call for heat and shut down. The low limit control will just restart the burner. Why would you want to do that anyway?

Sure you can - with modern controls. These new boilers don't have low limit, and sit cold between heat calls. No sense letting the heat go up the chimney or into the basement if it can go into a well insulated tank.

A boiler can also be well insulated and have no draft between calls.

Interesting discussion, Different ways add options that maybe have merit for some.
The video is illustrating with wood burned quick and completely...may not be best with coal as it has no issues most times burning slow and continuously.
Oil, as *RobR* speaks of, is another application and he reports of an American manufacturer that uses same basic principal. :yes:

I have used a Laddomat 50? since 1995 and it helps even out the heat

supply and demand.

There are many models depending on your needs.

The one I have allows a large storage tank to be charged when all other uses

are satisfied. In my system the tank is in series with coal boiler so the pump

runs 24/7 and transfers the excess heat from the burning coal to the water .

It prevents the water temperature from going too high .

It also has a bypass valve so if the boiler gets too hot water will circulate in

you radiators to cool the boiler down.

Mine looks like this.. There are many models.

Weil McLain’s one boiler is made over in Europe and shipped over here. Nice little boilers. With many nice features.

I had similar idea, I was considering ending one zone in a indirect tank that would of feed the water heater. Only problem is it doesn't work in the summer.

Efficient no doubt, but at what cost?

The same argument applies to gas mileage. Gas is simply too cheap to trade a car in just because of your less than stellar gas mileage. This boiler is probably almost $ 10,000 dollars here in Connecticut.
