Buffer tank

How thick is a wall of your buffer tank have?

Wall thickness is 2.5- 6 mm depending on cylinder size. We choose thickness that is verily suitable for 3 bar pressure heating systems.

I need to move 1000 litres buffer tank, but I have only 80 mm width doorway to that place.

All 1000l buffer tanks except LSX types are available with 790 mm width. These models are marked as LMG 1000 d790 etc.

What are the differences between the LMG, LMT, LVT, LSX buffer tanks?

Particular types differs in number and position of tappings and dimmensions. (height and diameter).
LMT type is best for domestic hot water (DHW), because it comes with huge stainless steel coil or tank-in-tank module.
LMG models have tappings in one row and rare sizes like 650 or 1200 litres.
LSX is best for a small spaces due to special diameters and heights.
LVT is standard buffer tank with a lot of 1 1/2" tappings in 2 rows and 1/2" for thermometers.

Do you provide special buffer tanks?

Yes, we can. As alteration are time consuming, we may charge for this.

Do you offer horizontal buffer tanks?

No, we don't. For better layering, have a look at lower LSX buffer tanks for low ceilings (or also narrow space).

What your buffer tank does stand on?

All buffer tanks are equipped with it's own stand. Any special modifications or welldings is not necessary.

What warranty do you provide for your buffer tanks?

5 years.

What is the lifetime of your buffer tanks?

The lifetime of a buffer tank depends on the external and internal influences that can damage the raw steel. This is mainly oxidation with oxygenated water. In the course of 8 years, we have not yet had a claim related to the lifetime of properly connected buffer tank. Customers order accessories for the tanks they bought from us 8 years ago. Therefore, the buffer tank should last for at least the average lifetime of the other part of the entire heating system.

Do you sell buffer tanks with copper coil exchanger?

We provide only buffer tanks with steel or stainless steel coil exchangers. For joining steel coil and copper tube use a dielectric union.


What do you charge for delivery?

Delivery prices may vary depending on buffer tank size, weight and delivery address. Please contact us for a precise quote.

What is the lead time on your buffer tanks?

It's approx 1-3 weeks. We can provide a very short lead times on regularly sold models. It is a good idea to place order as soon as possible to eliminate problems with delays.

Is a buffer tank on the pallet? How do I unload the tank?

Our buffer tanks are palletised. Normally they are unloaded by a tailift and they can be moved on a flat surface with a pallet truck. For further move, it is necessary to count with a cylinder's weight. You can find any tank's weight data by clicking on the main page on the tank's product line (e.g. LMG) and then click on the specific product type (e.g. LMG 1000 d790 0V).


Do you offer any insulation solution for your buffer tanks?

Yes, we do. Please check our solutions under an Insulation tab.

Can I use thicker insulation?

Yes, but we can provide only jacket with zip tailored to your required sizes.

Hot water

I would like to use the buffer tank also for a domestic hot water heating. Which buffer tank can you recommend me?

For a hot water heating we recommend the LMT type, which have a built-in stainless steel coil module with heat-delivery surface from 3.3m² to 5.1m².

What volume of hot water can be stored in the buffer tank?

Our buffer tanks are equipped by st. steel exchangers only, which works on a principle of heat flow. A heat-delivery surface of this exchanger is the key attribute. This size depends on the buffer tank size (in case of LMG, LVT and LSX types), or size of module (LMT). This information is available on product page of the buffer tank type and size.

Immersion heater

Is it possible to add an immersion heater to the buffer tank?

Our immersion heaters can be screwed into a G 6/4" thread. (on draws sometimes marked also as 1 1/2").

Is your immersion heater equipped with a thermostat?

Yes, all our immersion heaters are equipped with thermostat head for regulation and temperature control inside of the buffer tank.

Is there a space for immersion heater in the middle 6/4" thread on LMT type buffer tank? I'm not sure because of the large coil exchanger.

Yes, 6/4" thread in the middle of the buffer tank is suitable for the immersion heater, and coil exchanger is never in the way.
