Heating, DHW and Cooling

The efficiency of a heating system and the comfort of its users depend directly on the capacity and quality of the buffer tank and DHW storage tank. A well-chosen tank means lower energy consumption, stable temperatures and a longer service life for the heat source.

We manufacture domestic hot water storage tanks with built-in coils and buffer tanks for central heating systems, heat pumps, gas boiler rooms, biomass boilers and solar installations. Capacities from 500 to 60,000 litres — for boiler rooms, hotels, swimming pools, public buildings and industrial facilities.

All tanks in this category are manufactured in accordance with the PED 2014/68/EU directive and undergo pressure acceptance testing. Internal coils are made, among other options, from stainless steel for maximum heat transfer and resistance to water with elevated chloride content.

We support installers and boiler room designers in selecting the right buffer capacity — taking into account heat source output, demand profile, burner operating time and hysteresis requirements. We frequently combine a central heating buffer with a DHW storage tank in a single hybrid system.

Why our tanks?

Optional stainless-steel heat exchanger

On request, we manufacture the internal coil in AISI 304 — for maximum heat transfer and long-term corrosion resistance.

Capacities 500–60,000 L

From mid-sized boiler rooms to large industrial systems and district heating.

PED 2014/68/EU compliance

Every pressure tank undergoes the full acceptance process required by the EU pressure equipment directive.

Buffer + DHW in one

Option to integrate a central heating buffer tank with a DHW storage tank — compact and cost-effective.

FAQ — Heating, DHW and Cooling

The standard rule of thumb is 30–50 litres per kW of heat pump output, with a minimum of 300 L for small systems. For heat pumps with reversible defrosting, the capacity should be larger (50–80 L/kW). We determine the specific value after analysing the system diagram.

Yes — our storage tanks are fitted as standard with coils made from AISI 304 steel (or AISI 316 on request). This ensures long-term corrosion resistance, particularly in soft water or water with elevated chloride content.

Yes. We manufacture tanks with two coils (lower — solar, upper — boiler or heating element) as well as dedicated storage tanks for solar systems with connection ports for temperature sensors.

Yes — all tanks in this category are manufactured to specific order. We can produce intermediate capacities and heat exchanger configurations tailored to your project.
