Custom 6mm Sheet Metal Buffer Heat Accumulator for 30KW Wood-Fired Boiler in Basement

Will we see pictures after insulation?

How much did the tank upgrade cost?

I see a lot of professionals, maybe you know where to find a diagram on how to make a buffer, how big it should be, how to connect a 13 kW stove, gravitational, pump-assisted, DHW boiler in the installation

You drink Tyskie. Good.?

Hello,

Does the tank rust from the inside or is it somehow protected after cutting and welding? (sooner or later I will look for a supposed solution)

Other question...
We have an old oil stove at home and two 1000l tanks for resin oil.
There was a thought of converting the oil furnace into a pellet / eco-pea coal because it is supposedly possible for about PLN 3,000, but I thought the other way around, can resin tanks act as a hot water buffer or will they rather drown?

In the future, we will probably try to buy an air conditioner with the functionality of a heat pump and heat the water in the buffer with it.
The problem with the ready buffer is similar to the author of the topic.

Bringing in a ready-made buffer would be equivalent to demolishing a wall or demolishing a wall with a window. In other words, a considerable cost and the risk that something will collapse / crack (old buildings).

Does such an idea make sense?

Kind regards

Limescale should be deposited from the inside. Generally, in central heating installations, black elements are used instead of galvanized because corrosion is a lesser problem than scale. Even a stone can somehow seal any possible micro-leaks.

If it is really an epoxy laminate, it will withstand 80-90°C without any problems. I would be more afraid of polyethylene tanks, although it should also withstand - look for acceptable operating temperatures for devices made of an analogous material. The softening point of polyethylene and similar information.

When I manage to get there (because they are pressed into the corner of the boiler room), I will see if it has any markings. Previously, these tanks contained fuel oil for the oil furnace. On the other hand, the stove worked for 2 seasons and then the fuel shot up so much that I can sell the whole stove :P

But who will buy it and why?

It's not about whether corrosion is a "bigger or smaller problem" but about the fact that zinc as a steel protection fulfills its role at temperatures up to about 50 degrees C. In higher temperatures it is even harmful to steel (and copper) because instead of protecting it, it increases corrosiveness . It is generally prohibited in central heating installations.

Because most of my knowledge in the field of home CO solutions, I'll say that somewhere I came up with a thesis that at some point the stone will get into the installation and is supposed to be an anti-corrosion barrier ;P

Nevertheless, the thesis arouses quite controversial emotions, which is why I do not take it seriously

Hello
A house in the design phase.
He plans to replace the boiler with a wood-fired boiler with a storage tank at home.
As the boiler room is quite small, after installing a 1000l buffer there will not be much space left.

Solutions:
- Boiler and accumulation tank in the boiler room. Maybe we can take the bathroom, which is through the wall with the boiler room.

- There is a bathroom on the first floor directly above the boiler room. I could allocate a corner for a tank in this room. Reinforce the wall structure with a reinforced column to transfer the load. The boiler would perfectly fill the tank by gravity. The question is how the circulation pumps would cope with the distribution of hot water to the ground floor and first floor.

- Place the tank outside the building. For this purpose, make additional insulation and secure the pipeline well.
Alternatively, place the tank in a sealed concrete tank and make a boiler-buffer pipeline connection.

- Allocate space under the stairs for a buffer. Weld the cuboid yourself and adjust it to the rest height.
Initially counting the tank could fit 2000l. Open system, working at 1.5-2 bar. Does anyone have a self-made or commissioned tank?
How does such a tank behave, is it not deformed, is there no leakage?
The pipeline between the boiler and the buffer is about 4.5 meters long. Is this distance allowed? What diameter of the pipeline then: 1", 5/4, 6/4?

Your opinions please?
Thanks
