Fireplace 4-Hot Water Exchanger Installation Process and How It Works

Recently I have been thinking about installing an exchanger to the central heating boiler. Solid-fired boiler, fired from the top, regulator, thermometer, forced circulation,
oops sine - which is probably the most typical one possible.

I think so. The exhaust gases must have a certain minimum temperature at the chimney outlet to prevent tar condensation/soot deposition. I found information that the temperature should be no less than 70*C.

Due to the fact that the stove heats circulating water to 65*, the exhaust gas temperature is much higher. Of course, a lot of heat is lost in the chimney.

If an additional air-air exchanger was installed between the stove and the chimney and the sensor was placed at the top of the chimney. When the furnace is started, the sensor would be cold and the exhaust gases would go straight through the exchanger. However, if the outlet temperature exceeded 70*, the receiving fan in the exchanger would be activated
part of the heat.
In this way, only as much heat would be lost as necessary to maintain draft and prevent condensation. The rest would be used either to heat the basement room or to preheat the air supplied to the furnace.

And the question is: has anyone encountered such a solution? I looked for it, but I found it
only air-air and air-water exchangers for use in fireplaces. However, none of them was equipped with a sensor at the end
chimney.

Hello colleagues.
I have a question.
I have a Hajduk 14KW fireplace
The fireplace heats well, but I would like to buy a profile heat exchanger.
Exactly like that

At home I have a Vailant Ekovit gas furnace - probably 50KW condensing, but due to the large area of the house and terrible gas consumption fees, I would like the fireplace to additionally heat water to relieve the gas furnace.
And now the question is whether this exchanger is suitable for this?
Is it a good exchanger - structurally, because its undoubted advantage is that it will hang above the fireplace, so it should be efficient.
I`m waiting for your opinions.
Thank you

Dude, post the link to the manufacturer`s website because the Allegro auction is expiring so it has been removed, it`s hard to say whether it will be useful without knowing what exactly it is.

Sorry, I`m giving you the link now

Well, this exchanger will be suitable provided that you install it properly and tightly in the fireplace, you can`t do without a pump when it comes to heating the domestic hot water tank, and it would be best to do it in an open central heating system.

Well, that`s the problem with tightness.
Kwasiak works at high temperatures and I am afraid that the chimney will leak where two pipes will lead out.

Which option would you choose, the one I mentioned earlier or something like that

I don`t know which exchanger will be better and which one will be more efficient.
I`m waiting for a reply from you

The latter option is more advantageous. There will be no problems with heating the boiler.

And I have a problem, I have a workshop about 70 meters away, there is an attached room with a fireplace, a regular one without a built-in water jacket, I am going to buy a jacket mounted on the exhaust pipe.

I want to connect the ST 120l 1-E JUNKERS tank for this purpose


and under it there are about 3 central radiators and hot water under 2 taps. Will it all pass the test?
according to this scheme:


kind regards

I have such a 1 meter exchanger on a flue pipe, 3 radiators and an underfloor heating system connected, approx. 50 meter of pipe + tank approx. 100 l, it works without any problems, the pump turns on periodically, unless I burn the fire in the fireplace very strongly, the system will rock so much that the pump works continuously (temperature on the pump controller 55 degrees)

Hello everyone. I would like to seek advice regarding the exchanger. Namely, I would like to build a fireplace that will distribute heat using a fan (distribution pipes are installed in the ceiling above the plasterboard), and install an exchanger that would be used to heat the bathroom floor and heat a boiler of about 100 liters. The floor area is 6 m2. and the total heating area is 57 m2. I`m thinking about a 12 kW fireplace and a meter heat exchanger. Can such solutions be combined? And if so, how can I make it blow warm air through the channels? I am asking for professional advice.

Hello

I have a LaVita goat with a water jacket. According to the seller, power 14kW = 10 kW mantle + 4 kW fireplace through radiation, glass and casing. In my opinion, the power gain is reverse jacket 4 kW and casing 10 kW. The small volume of the boiler and therefore poor flue gas swirl result in, in my opinion, poor boiler efficiency. Once lit, the goat emits visible embers from the chimney - I burn it with dry seasoned wood.
This prompted me to build an acid exchanger to increase the thermal efficiency of the goat. Everything looks like in the attached photos. Exchanger connected in parallel. Power cables hidden in the plasterboard construction.
The power of the system has significantly increased. My only dilemma is whether there is condensation on the surface of the exchanger? Does the condensate damage the goat heat exchanger? I have no way to check whether condensation occurs at all.
Maybe change the exchanger connection to serial? Would water from the shell enter the exchanger at the outlet and condensation would not occur?
