6m by 4m Adman Thermastore, will be used by all the family, pool table, darts, exercise, double glazed pvc door and window.

Would like to keep it from freezing when not in use, what are the best economical options??

If it's properly insulated it shouldn't get literally freezing, as the temperature in Ireland averages more than 0C over the day-night cycle except in incredibly rare cold snaps, so you'll just see the temperature fluctuate around that average.

When occupied the most efficient option is a single-room MHRV. This is a UK site but just for examples...

Different models work in different ways. From memory the single-pipe ones work on an alternating intake/exhaust cycle (e.g. every minute or so), the dual-pipe ones work continuously and are supposed to be better in windy locations.

Alternatively you can just rig up the cheapest possible resistive element heater to an accurate thermostat-controlled plug and set that for a couple of degrees above zero.

Some people have had good results with IR heating panels in such sheds and offices, but these tend to be better for situations where the user is stationary as the surrounding air isn't heated, only the biological object which absorbs the IR radiation.

You would need a primary source of heating in addition to this.

That would be way over my head, just looking for something plug n play, maybe wifi enabled, that wont be ultra expensive to run, if such thing exists. Budget 300ish 🤔
