Circulation pumps, room and boiler thermostats, pure sine wave UPS units and gas detectors – everything for a dependable boiler room from a single brand, in stock in Žilina and backed by technical support over the phone.
updateUpdated: verifiedTechnically reviewed by the ATRIA SK s.r.o. technicians
AVANSA® is a brand of heating and safety equipment distributed across Europe by ATRIA Slovensko s.r.o., based in Žilina, Slovakia. The range covers what almost every family-home boiler room needs: circulation pumps for central heating, room and boiler thermostats, backup power supplies (UPS) for solid-fuel boilers, and gas and carbon monoxide detectors.
AVANSA circulation pumps have a cast-iron body and an asynchronous motor with three speeds, selected directly on the terminal box. They handle media from -10 to +110 °C at working pressures of up to 10 bar. The room thermostats are suitable for controlling most boilers with a switching voltage of 24 – 230 V and come in both wired and wireless versions. During a power cut, the backup power supplies deliver a pure sine wave output, so the circulation pump keeps running and the boiler can cool down safely. Gas detectors with a sensitivity of 10% of the lower explosive limit (LEL) can shut off the gas supply automatically when supplied as a set with a solenoid valve.
On this website you will find an overview of the full range, technical specifications, comparisons and practical advice on selection and wiring. All products are available from the ATRIASHOP.EU online store – most of them shipped straight from our warehouse in Žilina. Installers, heating contractors and resellers can buy on wholesale terms via atria-europe.com. If you are planning a complete heating system, take a look at our specialist website on H.P.W.® brass manifolds as well.

Most people are not looking for a brand but for a solution to a specific problem. Here is a shortcut to the right product.
Measure the installation length of the old pump (130 or 180 mm) and check the thread on the pump body (1", 6/4" or 2"). For a typical family home, an AVANSA circulation pump with a 6 m head is then usually enough, or the economical 4 m version for smaller systems. If you used to have an Aquart pump, we now sell the same models under the AVANSA brand with the same size designations.
If the water heater is far from the bathroom or kitchen, the AVANSA CP 15-1.5 recirculation pump will help. It keeps domestic hot water circulating between the cylinder and the taps, so hot water arrives almost immediately and does not run needlessly down the drain. It has a brass body suitable for drinking water, a power input of 25 W, a G 1/2" connection and a cable with a plug. Add a timer switch so that it runs only when you actually use hot water – for example in the morning and evening.
A solid-fuel boiler needs water to keep circulating even during a power cut. The basis is an AVANSA boiler backup power supply with a lead-acid battery, together with an AVANSA 110 C or 110 E pump controller, which switches the pump according to the boiler temperature, and an STS safety valve for the cooling loop. A carbon monoxide detector also belongs in the boiler room.
The biggest saving comes from an AVANSA room thermostat with a weekly programme – the boiler does not fire when nobody is at home and holds a lower temperature at night. If you do not want to run a cable, choose the wireless 2007 TX model. On the pump, set the lowest speed at which all the radiators still heat up.
A kitchen or boiler room should have an AVANSA gas detector – near the ceiling for natural gas, near the floor for LPG. In a kit with a solenoid valve, it shuts off the gas supply by itself in the event of a leak. The 150MC detector protects against carbon monoxide from a boiler or stove.
The AVANSA pump and thermostat are only part of the system. You will find manifolds with flow meters on the H.P.W.® brass manifolds website, and a heating installer or our technical support can help you size the number of circuits and the amount of pipe.
Six steps, from the pump to protecting the boiler against dirt. Each step links to a page with a detailed selection guide.
The key factors are head, flow rate, installation length (130 or 180 mm) and connection thread (1", 6/4" or 2"). A head of up to 6 m is usually sufficient for a typical family home, while larger and multi-zone systems need 8 m. Pump speed is set with a three-position switch. You will find an overview of the models on the Circulation pumps page.
During a power cut, the UPS immediately powers the pump from the battery so that the boiler can cool down safely. Allow a margin for the pump's start-up current – a 500 W unit is suitable for loads of up to approx. 250 W in total. Help with choosing the model and battery is on the Backup power supplies page.
The AVANSA 110 C or 110 E controller switches the pump on only once the boiler exceeds the set temperature and switches it off again after it has cooled down – depending on how the boiler is used, this can save up to 60% of the electricity and extend the pump's service life. The 110 Z model adds DHW cylinder heating, the 110 R controls two pumps and the 110 S a solar circuit. More on the Thermostats page.
The manual AVANSA 2003 maintains a single set temperature, while the programmable AVANSA 2007 allows up to 6 temperature changes a day according to a weekly programme. The TX versions work wirelessly with a receiver next to the boiler (range approx. 50 m) – particularly handy when renovating older buildings. See the comparison on the Thermostats page.
A gas boiler should always be paired with the AVANSA 100M gas detector – supplied as a set with a solenoid valve, it shuts off the gas supply by itself if a leak occurs. Carbon monoxide, which a gas detector cannot pick up, calls for the separate AVANSA 150MC detector. More on the Detectors page.
The Aras 3/4" magnetic filter captures ferrous debris with a neodymium magnet, while its filter mesh also traps non-magnetic particles from radiators and pipework. The pack includes a swivel boiler connection, a G3/4" ball valve and a spanner, and the magnet is easy to remove for cleaning. Maintenance tips are in the Advice section.

A gas boiler simply switches off during a power cut. A boiler burning wood, coal or coke, however, cannot be stopped like that – the fuel in the firebox keeps burning until it has burnt out. If the circulation pump stops, heat is no longer carried away to the radiators, the water in the boiler overheats and the central heating system is at risk of boiling. The result can be a damaged boiler, leaks or a dangerous condition of the whole system.
The AVANSA backup power supply (UPS) is designed for exactly this situation. When the mains supply fails or the voltage falls outside the normal range, it switches to battery automatically in less than 4 ms, keeps the circulation pumps running and lets the boiler cool down safely. The switch-over is indicated on the display and by an audible signal. The output voltage is a pure sine wave, identical to the mains voltage in your home, which suits the motors of circulation pumps. Once the mains supply returns, the unit recharges the battery.
A circulation pump is an inductive load and may need up to twice its rated power when starting. That is why it is recommended to load the backup power supply to no more than 50% of its maximum output:
Add up the power input of all the pumps the unit is to back up, plus the boiler electronics if applicable. With three-speed AVANSA pumps this is a matter of tens of watts – the 25/6/180 model, for example, draws 93/67/46 W depending on the selected speed.
The backup time depends on the battery capacity and the actual load. Approximate values:
You will find a complete overview of models and specifications on the AVANSA backup power supplies page.
A leak of natural gas or propane-butane can lead to poisoning, suffocation, fire or explosion. The AVANSA 100M detector picks up gas at a concentration as low as 10% of the lower explosive limit (LEL) with a response time of under 30 seconds and triggers a visual and audible alarm of more than 90 dB. As a set with a solenoid valve (G1/2" DN15, G3/4" DN20 or G1" DN25), it also shuts off the gas supply by itself.
Carbon monoxide (CO) is colourless, odourless and non-irritating, so poisoning strikes without warning – a sleeping person may not notice it at all. A gas detector cannot recognise carbon monoxide or smoke. CO calls for the separate AVANSA 150MC detector with a sensitivity of 150 ppm ± 80 ppm and an alarm of more than 85 dB.
You can compare all models and valve sets on the AVANSA detectors page.
A few simple tasks at the right time extend the life of the pump and battery and ensure that the safety equipment works when it is needed.
