ᐅ Is a multi-split air conditioning system suitable for heating?

Does anyone here use a multi-split system for heating, for example as an alternative in older buildings when insulation or renovation is no longer worthwhile?
I’m not familiar with the various split systems, but I’ve come across them often as an alternative to conventional heating when insulation and renovation hardly make sense anymore for the current residents.
I would have concerns about noise, drafts, and the resulting dust circulation since it is an air-to-air heat pump after all.
A photovoltaic system would at least be available for the transitional period from spring to autumn.

Grolsch307 Aug 2022 15:12I have one more question: how did it go with the electrician? Did you have to find one yourself? If so, how did you coordinate the timing?
What I mean is, in my case I have to arrange the electrician myself, so I need to make sure they don’t arrive too early to avoid them waiting around, which costs money. But they also shouldn’t be late, or else the HVAC technician might leave, and if any issues come up, I’ll be left not knowing what to do.
About how much does an electrician cost?
Have a nice Sunday 🙂

What exactly are you supposed to provide on-site according to the offer? A permanently present electrician? ;-)
In my case, the power supply line to the outdoor unit – which provides electricity to the entire system – had to be available. I already had electricity on the roof, so that was taken care of.
The HVAC technician connects the outdoor unit to that line, then runs cables along with the refrigerant lines to the indoor units. Done.

What I mean is, in my quotes, I have to hire the electrician myself, so I need to make sure they don’t arrive too early, otherwise they’re just standing around, which costs money! But they also shouldn’t come too late, otherwise the HVAC technician will be gone, and if problems come up, I’m stuck and don’t know what to do.
Approximate cost for the electrician?
Have a nice Sunday 🙂 I’m not exactly sure how much the electrician costs since I haven’t received an invoice yet. Around 150€ (about $160).
I only needed one power cable (3x2.5mm²) for the outdoor unit. The HVAC technician provided all remaining wiring to the indoor units. It would be totally unnecessary to have the electrician do that part. They run the wires through the same installation channels, and the indoor units are connected to the outdoor unit.
So the electrician only needs to install one power cable per outdoor unit, on my side connected to a 16A circuit breaker.
Hello everyone,
I am currently looking for a solution to replace my gas heating system, as it will not last much longer due to heavy calcification. Naturally, an air-to-water heat pump seems like the obvious choice, but I am also interested in possibly using an air conditioning system for heating. Combined with a photovoltaic system, it could also provide cooling in the summer.
The property is an end-terrace house with 120m2 (1290 sq ft), built in 1963 and renovated in 2007 (aluminum windows, pipes, electrical system, and roof).
If an air conditioning system or a multi-split system is considered, it should function as the sole heating source. However, I am wondering how this would work for the bathroom and hallway. Infrared panels could be a possibility, at least for the bathroom.
Does anyone have experience with something like this, especially for very cold winter conditions? What about noise levels and indoor air quality?
Thank you in advance.

I now have a multi-split system with four indoor units.
I can only share how it has been during the summer so far: nicely cool and very quiet. At night, the bedroom window no longer needs to be open, maintaining a comfortable temperature continuously.
Since my gas price is increasing to 15.88 cents per kWh starting from 1.10.22, it no longer makes sense to use underfloor heating with gas.
I will use the air conditioning system for heating instead. It has a SCOP value of 4.6.
In simple terms: the electricity price would have to be above 73 cents per kWh for gas to be worthwhile.
Currently, however, the electricity price is at 30 cents per kWh.
Therefore, gas will likely only be used this winter for heating water, supported by two solar thermal collectors for hot water.
