ᐅ Night Storage Heaters vs. Air Conditioning / Infrared Heating

Nilius80Dear forum members,
I am hoping to support my decision-making process regarding the installation of a new heating system.
Current situation:
1- Two-family house, solid construction, built in 1960.
Heating is provided by night storage heaters, using a night tariff.
Completely new windows with double glazing were installed in 1993.
In 2005, the facade and roof were fully insulated.
The roller shutters were also replaced at that time and are now externally mounted or are venetian blinds.
However, the house is not used as a residence but as office space (Monday to Saturday).
Hot water demand is low, limited to handwashing and cleaning, supplied by small boilers (a total of 3).
Due to the insulation added in 2005, heating demand has significantly decreased, with about 50% less nighttime electricity consumption.
Most rooms have a PC and other electric devices that generate some basic heat. In some rooms, no additional heating would be needed; for example, the server room also warms the floor of the room above.
In most other rooms, it is sufficient for the night storage heater to run at about one-third capacity.
The fan is hardly ever used.
Heating season runs from mid-November to the end of February.
In the attic (2 rooms), an air conditioning unit was installed in 2014, mainly for cooling, but it can also heat the two rooms adequately. After about 15 minutes, it reaches 20°C (68°F), then runs in automatic mode about 5 minutes per hour. The warmth is not very comfortable, but tolerable for work.
My current problem is that the old night storage heaters are gradually failing; they can no longer be properly controlled and sometimes only operate at full power or not at all. :-(
I have been researching heating options for weeks and am torn between air conditioning systems for all rooms or infrared wall heaters. I have also considered a natural stone heater.
Does anyone have experience in a similar situation?
Who has experience with infrared heaters or air conditioning as the sole heating system?
What is your opinion on natural stone heaters?

ErikErdgas2 Jan 2017 10:22Hello Nilius80,
I think the first step should be to determine the heating demand. Are the office spaces used continuously, or are there frequent tenant changes?
I would recommend consulting a qualified energy advisor who can carry out a thorough data assessment and, based on that, present various options. Besides the installation costs, you also need to consider the operating costs and, for certain technologies, maintenance costs.

Hello,
I agree. One clear issue here is the absence of a hydronic heating system for generation, distribution, and transfer.
Electric direct heating is significantly and noticeably more expensive compared to other systems, but from an investment standpoint, it is moderate.
Best regards,
