Hello everyone,

We are currently at the stage of deciding on the heating system for our house construction. We have decided to use an air-to-water heat pump and have chosen the Viessmann Vitocal 200S model AWB-M-E. So far, so good.

Now we need to decide on the controlled residential ventilation system. Our heating installer has presented us with the following options:

1. Helios Controlled Residential Ventilation EC 300 W R
2. HOVAL HomeVent comfort FR 301

According to the installer, the main difference is that with the Hoval system, you do not need to buy and connect a separate enthalpy exchanger, as this is already integrated (or otherwise technically unnecessary, with the same function). The price difference between the two is only €400 (Helios being more expensive), so this is not a major factor in the overall cost. There is some information available online about the Helios unit, but unfortunately not much about the Hoval.

Therefore, my question is: Has anyone already had experience with these devices or with either of them, and can offer some advice? What should be taken into account? Which would you choose and why?

Many thanks in advance for your support!

Best regards,
Michael

Really, no one with experience using either of the two devices? Any opinion helps.

These devices are not very common. The standard (most sold devices) is usually either Valox or Zehnder. There is a lot of experience with these and quick support available when needed. We will be getting a Zehnder ComfoAir Q.

How large is the house?

I would lean towards the Helios with enthalpy exchanger.

The house (built with a timber frame and without a basement) has a total area of 183 sqm (1970 sq ft).

Phew, regarding the living area, it is already clear that both systems are undersized. I would not go below 350, rather closer to 400 (whichever manufacturer).
