1. What are the advantages of volumetric multi-functional heat exchangers?
By installing our heat exchanger, we provide our customers with the following measurable benefits:
- simple and well-proven solution for connecting various sources of heat to a heating system,
- more free space in a boiler room,
- good investment – purchase of a single unit instead of several separate units,
- safe operation – 10-years guarantee,
- profitability without any additional costs during everyday operation
2. Where our heat exchangers can be installed?
We design our heat exchangers to an individual order.
They can be installed virtually everywhere as we adopt their dimensions, i.e. width and height, to individual customer’s needs.
3. Is it possible to connect our heat exchanger to existing heating systems?
Obviously yes.
Our innovative solution allows for modernization of any boiler room.
By using our heat exchanger we can connect various sources of heat to multiple central heating and DHW systems.
4.What is the difference between a hot water reservoir and a heat exchanger?
The difference between these two devices is in their principles of operation. Click here to see the visualization
Hot water reservoirs collect domestic water.
Water in a reservoir needs reheating, no matter if hot water is really needed or not; therefore unnecessary costs are unavoidable.
Volumetric heat exchangers contain boiler water which accumulates heat generated by various sources of heat.
Copper coil pipe installed in the upper part of the heat exchanger allows for the heat exchanger to function as a constant-flow feedwater heater.
Heat exchanger accumulates the heat and heats up the domestic water, both of which lead to minimum loss of accumulated energy (i.e. heat).
5. Is it possible to use solar collectors to heat a house?
By installing a solar-collector system with a reservoir we create a solution adopted exclusively for DHW, and the investment pay back time is twice longer.
By installing solar collectors integrated with a multi-functional heat exchanger we ensure that the heat accumulated in the heat exchanger can be used both for DHW and central heating system purposes.
As the result, the investment pay back time is shorter and the operating costs are reduced.
6. Do we need a cathode or an anode?
Hot water reservoirs require the use and regular exchange of a cathode or an anode.
Lack of their use results in boiler scale deposition and shorter lifetime.
If unused for a long period of time, at the temperature below 70ºC the domestic hot water can be susceptible to the water ageing effect and Legionella development.
By using a DHW coil pipe we eliminate the need to install a cathode or an anode and we avoid Legionella development.
7. Is your heat exchanger capable of supplying hot water to a whole family?
It happens quite often that the capacity of a hot water reservoir (e.g. 200 litres) is not sufficient for a three or four-person family and, as the result, at a certain point the hot water supply runs out which gives a feeling of discomfort in using the DHW system both for inhabitants and guests.
The efficiency of a copper coil pipe installed inside a heat exchanger is 16 l/min, which ensures immediate and unlimited access to hot water.
In other words: HOT WATER NON-STOP!!!

8. Why heat exchangers are combined with solid-fuel boilers or a water jacket fireplaces?
A heat exchanger in combination with a solid-fuel boiler or a water jacket fireplace works as a BUFFER, i.e. an accumulation tank.
Why?
To ensure that sources of heat achieve:
- their nominal power,
- maximum efficiency, and
- maximum lifetime.
Heat exchanger – works as an accumulation tank which accumulates heat surplus generated by a solid-fuel boiler or a fireplace and transfers it to the central heating and DHW systems.
This solution ensures that the accumulated energy can be use at a later time:
e.g. when, at night, a boiler goes off due to lack of fuel heat is not lost.
Accumulated temperature allows for continuous operation of the heating system until very morning and ensures availability of DHW for inhabitants who just woke up.
Another functionality offered by a heat exchanger is that it secures uninterrupted operation of a boiler or a fireplace when the power is cut off.
Correct installation of piping and a pump at the boiler inlet, including a by-pass, allows for gravitational flow of water in a boiler-heat exchanger or a fireplace-heat exchanger systems.
By receiving the heat surplus from a boiler or a fireplace the heat exchanger delays or prevents overheating of a boiler or a fireplace
9. What is the difference between a plate heat exchanger and a volumetric heat exchanger?
Plate heat exchangers only ensure transfer of heat and do not accumulate heat as volumetric heat exchangers do.
10. Why do we need to accumulate heat?
Accumulation of heat from various sources ensures measurable benefits, i.e. reduction of costs.
An accumulation tank is an equipment which concentrates heat – i.e. the difference between what was generated by sources the of heat and what was consumed by the heat receivers.
After the heat has been accumulated – we can effectively use it when sources of heat do not work (e.g. when a fireplace or a boiler went off, when the sky is cloudy and collectors do not work); the heat accumulated in a multi-functional heat exchanger can be supplied to the heating system for up to dozen hours (depending on the capacity of a heat exchanger and the effective consumption of heat).
Accumulation of heat is a very good idea for EFFECTIVE use of renewable energy.
11. What is the system inertia?
The more capacity of a heat exchanger the larger inertia of the whole system.
At large consumption of heat, e.g. several central heating systems – radiators and floor heating plus large consumption of hot water, the tank capacity (i.e. tank inertia) is a source of comfort for the user: all sources of heat are fully capable of generating and supplying heat to central heating systems and domestic hot water systems without interruptions in energy supply.
