Vaillant set with a 120-litre storage tank
A set consisting of a Vaillant atmoTEC/turboTEC VU CZ/SK low-temperature boiler with an external VIH R 120-litre storage tank is suitable for a typical 3-4 person household with average hot water consumption. It's a popular mid-range volume - sufficient capacity without an unnecessarily large storage tank.
Here you will find models such as Vaillant atmoTEC plus VU 200/3-5, 240/3-5 or turboTEC plus VU 202/3-5, 242/3-5, each with a VIH R 120 storage tank. The boilers are low-temperature (non-condensing), so they have lower efficiency than condensing models - suitable especially when replacing the same type in an existing system. If you're setting up a new system, we recommend also considering condensing alternatives.
When choosing the output, base your decision on the heat loss of the building; for the storage tank volume, base it on hot water consumption - for a smaller household even 70 litres is enough, for a larger one we recommend 150 litres.
